Function Generators

Since much of this information comes from the mid to late 1990s, it is obsolete due to the number of new function generators that are now available for Rife and other RF work. It is provided for historical purposes or for those renovating old machines.


I have decided to add on the Entrainment Circuit to my system, I am using a Geny-2 as my MOR generator, and thus I have to make a slight modification to Jim Bares ciruit diagram. Thus instead of using 3 BNC connnectors I am going to use 2 CB Male Connectors which are hooked into the cirucuit board and 1 BNC connector which I plain to hook into a BK4040 for the Gate in. Mr. Turf suggested I use the following diagram when re-wiring into the circuit board.

"There was a BNC to male CB plug cable made by the Geny folks that allowed the Geny output to use a BNC splitter and be connected with another generator. You could make the same thing for yourself, just get a male CB connector.

The pinout is

4 pin Miccolor9 pin conn
1green3 (common)
2white1 (signal)
3red5 (NO Tx)
4black4 (NC Rx)
Shell7 (ground)
The mic pin 4 is not used. The Geny switches its pin 5 (CB pin 3) closed when it transmits which makes the CB transmit, which is the same as pressing the mic button. This allows the Geny to stop the CB transmitting when the Geny is done running frequencies. We often tie this to pin 1 so it is always grounded, and the CB is always transmitting when it is on."

>I cannot tell from anything I have read if a voltage reducer is necessary on the Ramsey

It isn't. On-off switch is built into the voltage amplitude switch. (Which is a pain in the butt because you have to recheck your voltage level everytime you turn it on, unless you put a mark on the Ramsey and are fairly accurate about turning the knob to that mark).

Mine, in squarewave mode, is adjustable from slightly above 0 volts P-P to at least 3 volts P-P.

>What is the frequency capability of the device?

There are two frequency modes. In the one mode: 0.1 Hz to 5999.9 Hz in 0.1 Hz increments In the other mode: 1 Hz to 59999 Hz in 1 Hz increments



Ramsey works real well. No voltage reducer is necessary and voltage is adjustable enough to overdrive CB (to get outside of CB Hz limitations) to 1.8 volt w/o problems. The only downside IMO is no pulsing is available via the unit. A unit to pulse the signal can be made and added to where the signal is output, but it is beyond my limited electronics knowledge now.

Don is selling a unit that has keypad entry and has pulsing (don't have his URL available this moment). It is fairly reasonably priced. I don't think it is has high enough voltage for a pad device though w/o modifications.

I would like to see one that is reasonable that also has high enough voltage to be used as a pad device as well as variable pulsing.

You find it, please let me know.

Good Luck,

Bob Carver


>I am considering purchasing another function generator,


My brother just bought one of these (SG100A) with the option of upgrading it to a 50Mhz model that will be out in a few months. It is a really nice unit and not expensive when compared th HP and Wavetek generators with the same capabilities. We just got it his rife system going this weekend so should be able to say more about it later.

He also got a MFJ_969 tuner that works really well with Ralph Hartwells Transmission line instead of Balun. It has a built in dummy load as well as a roller inductor.



Hi Turf,

I see that you are interested in squarewave generators. I don't know if you know about the one that I developed or not, but I'll include an attachment about it below. It is computer controlled and is cheaper than the other generators, although not as portable.

Take Care,


************************ Attachment *****************

I have developed a squarewave generator that is PC based and is a combination of a software program which I call RifeGen and a hardware device which I call SquareOne. It will run on any old IBM compatible PC, 8088, 286, 386, 486 or pentium except Compaq brand computers and possibly Commodore brand computers don't seem to be truly IBM compatable. It uses the speaker port of the PC to output the signal, which is then fed to the SquareOne. The signal produced in a PC in this manner is not suitable to be used as a squarewave without modification because the wave can look like a poor squarewave, a triagle or even a sine wave. The SquareOne takes this very ugly signal produced by the PC and turns it into a nice square wave, does frequency division, beeps when finished, displays signal activity of the output, varies the amplitude of the output, etc. So the software and hardware are needed together. It does require the PC to be opened up and a jack installed between the speaker and where it connects to the motherboard. No soldering is required because I have everything wired to 2 connectors which just need to be plugged together.

I have many features built into RifeGen which are not available on other squarewave generators. RifeGen has 100 banks of up to 36 Program Groups (3600 Program Groups). Each Program Group can contain up to 30 individual frequencies, sweeps, burst mode or waver modes. In addition to the automatic program groups, there is an immediate mode where you can quickly run an individual frequency, sweep, burst or waver. Burst mode operates at a burst repetition rate from .1 Hz to 8 Hz, user adjustable. Waver mode will waver around a central frequency. The deviation from center, step size and step duration are all user adjustable. All of the parameters such as burst frequency, deviation, step rate and duration per step are user adjustable from either an options screen or dynamically within the program groups.

Program groups can also be used to hold logs if you wish to keep track of sessions. Also a "Master Frequency List" is included with different conditions and their associated frequencies. This allows rapid program group creation without having to look up frequencies in a book. Just copy and paste into a program group, add times and options, then run it.

Frequency range is from .185 Hz to 10,000 Hz in steps from .005 Hz below 37 Hz and steps of 1 Hz from 37 Hz and above. You can run all modes within this range either immediately or automatically within program groups. I currently have 2 output interfaces, Bare/Rife and Biotec. The Bare/Rife interface has a variable output from 240 mvac rms to 1.8 vac rms to a BNC connector. The Biotec interface is a DIN connector with 5 v P-P, +5 v and +12 volts.

Neither the Ramsey or Kinneman have any of these features. Also they have slow rise times on the leading edge of the Sq wave.



This may be late news, but anyway -

You can find some info on the Ramsey SG-550WT on their web site

Choose "Hobby & Amateur Radio Kits", then "Test Equipment"

The Ramsey comes wired & tested for $270, or in kit form for $160?

The phone number to Ramsey Electronics is (800) 446-2295 and their hours are 9-6pm EST. I hope this helps.


Global Specialties: 800-572-1028 <A HREF=""></A> have a function gen you should like. Model 2003 is a synthesized unit with 16 memory slots, freq DC to 1.6Mhz, offset, 20 V p-p.

The F1B Kinnaman has a variable voltage output and a variable pulse rate. It is not adjustable for duty cycle.



X-Sender: (Unverified)

Hi Brian. Our generator, the Semoia pg-4 is a manually controlled gen., with a range of 1-9999 Hz. in 1 Hz. steps. The voltage is adjustable (0-2.5V), though the duty cycle is not. This generator has a very fast rise time (I don't remember offhand what it is); though it is lacking a keypad. Ed Heft revamped the Kinnaman for us, removing the analog freq. dial and installing a voltage adjustment (0-2.5V) -- I find that the Semoia is not susceptible to RF in the lines and in the air, as the Kinnaman tends to be (I find it tends to crash when used with our normal tube configuration, which is an inconvenience) This is the generator in practically all our R/B machines these days, and it's manufacturer is working on a fully programmable version this Spring.

We may be able to sell a very limited number of these on urgent request (there are a limited number made, and we use a lot of them.

RE ----------------------------

I have a Ramsey SG-550 and I remember measuring the rise time as being fairly poor, something on the order of 120nS. Also, the duty cycle quivers about and is preset by a potentiometer which is very hard to set precisely. This would cause the harmonic content to be unpredictable (maybe a good thing?). I also own a B&K 4040. This generator has very poor frequency control (analog RC oscillator) but a very good square wave. I have measured its rise time at 18nS.

If you are modulating the radio through the audio circuits, though, I don't think the rise time of the generator is a concern. The poor frequency response of the audio circuits would preclude any worry about the square wave quality. This could probably be improved somewhat by reducing the value of the ceramic RF bypass capacitors that are used in the audio circuits, if someone wants to go to the bother. Still, you're contending with active devices that weren't spec'd out for fast switching times. And don't forget the audio output transformer. With its very high inductances and core losses, it will eat most high-frequency energy for lunch.

Bottom line --- I think someone should only be concerned about a generator's rise time specification if they are going to use it to directly modulate/gate/switch the RF circuits. This is the only modulation approach that closely translates the square wave quality to the RF modulation envelope quality.

BTW, any generator having a lousy rise time could be greatly improved by running the square wave through a high-speed buffer amplifier with hysterisis. This circuit "snaps" to a high or low voltage when a slowly-changing input reaches pre-defined thresholds. There are IC's designed just for this purpose. If anyone is really interested in experimenting with this, I'll research the books and forward more info.



On an unrelated note - it's really nice to be able to program the entire session into the frequency generator, and then forget about it. No wonder you guys don't take SWR/power readings for every frequency, you don't have to go near your equipment to change the frequency.

The Kinnaman F1B produces only positive offset (0 to +X volts) squarewaves. There is no on-off switch. You have to unplug it to turn it off. You can adjust the gating frequency. The max frequency is 9999. The F1B's output voltage level is adjustable from 0 to 5 volts. It came preset to 0.43 volts (IE. squarewaves ran from 0 to 0.43 volts). It came with minimal documentation. (For example, exactly what does 'deviation' mean?) It has a 90 day warranty - but only if the case is not opened. (So they wouldn't let me take it apart to see what's inside. Darn.)

With the 0 to 0.43 volts, and a frequency of 2182 Hz, the falltime of the squarewave was less than 50 ns. (I didn't get around to looking at the risetime.)

The husband of the dog-owning couple found the 4Hz gating to be mildly annoying. I, as always, felt nothing.



I'm Gary Dickerson of D&H Solutions LLC. We have just finished development of GENY-1, a PC expansion board that plugs into any available 8 bit ISA slot from the original PC to today's Pentium II with 512K RAM. The software is DOS based and has been tested to run all versions of DOS and Windows. We designed GENY-1 this way to allow universal usage. Also, to all those like myself who just cannot bring themselves to depart with there older model PC's when upgrading to the latest and greatest, this allows you to blow the dust off and put them to some good use.

Before I go any further, I would like to take this opportunity to publicly thank Jim Bare for all his time and effort in helping us test and fine tune GENY-1.

I also want to thank all those who have responded to us off list about their interest in GENY-1. I will reply to each of you as soon as possible. For the time being I will try to answer as many questions as I can in this e-mail. I am currently constructing a WEB page that I hope will be ready in about a week.

GENY-1 grew out of my own personal frustration with setting frequencies after building the Rife/Bare unit using the Lodestar Model AG-2603AD to generate the frequencies. This is a very fine unit, but I was spending more time setting the frequencies than running them. Anyhow, I hope GENY-1 will make life a little easier for anyone interested in purchasing one.

OK, lets answer some questions.

Q. What exactly is GENY-1?

A. GENY-1 is a Programmable Digital Frequency Squarewave Generator. The unit consists of a PC circuit board, a 10 foot interface cable and a diskette containing the software. The frequencies, time intervals (from 1/10 second to over 15 minutes per frequency) and squarewave shapes are all user definable. The squarewave shape defaults to 50% and only requires optimizing at frequencies below 200 Hz or by those researchers wishing to experiment.

Q. What equipment will GENY-1's cable connect to? A. GENY-1 can connect to any desired device you'd like. All we need is the Model of your particular device and if we have the pinouts available to us we will custom make your cable. If your device is not listed in our reference books we will require the pinouts be supplied to us. The documentation that ships with the unit includes GENY-1's cable pinouts for anyone wanting to make their own cables for other devices. Future cables can be ordered from us as well.

Q. How many frequencies can be inputted at one time and can they be saved? A. The software allows for 16 pages of 16 lines for each page for frequencies to be inputted. It has 3 modes, Stop, Next, Repeat. "Stop" will run anywhere from 1 to 16 frequencies and stop after the last one. "Next" will continue on to the next page if your protocol has more than 16. "Repeat" will run a page of frequencies and then start the sequence over and run until manually stopped. You can save multiple files of 16 pages each and they can even be shared with other GENY-1 users via e-mail attachments.

Q. What is the range of frequencies for GENY-1? A. GENY-1's range of frequiences is from 2 Hz. to 20,000 Hz.

Q. What is GENY-1's output voltage? A. We put an attenuator (to regulate voltage) onto the GENY-1 board. The range is from 0 to 3 Volts Peak to Peak. The board is jumpered to ship with an optimum fixed voltage for those not interested in experimenting. For those who are, move a jumper and get your scopes out.

Q. Can GENY-1 do swing and pulse frequencies? A. GENY-1 can be configured to provide for swing or pulse frequencies.

Q. What is the price of GENY-1? A. GENY-1 sells for $199.00 U.S. plus shipping & handling. For shipments within the U.S, add $15.00 and shipments outside the U.S., add $35.00. Shipment for now is via FedEX. I'm looking into complementary shipping options to lower those rates and hope to offer a choice in the future. NOTE: Florida residents please add 6% sales tax.

Q. How do I order? A. Send your Name, Shipping Address, and the Name and Model # of your device, along with your payment to:

D&H Solutions LLC 12088 Anderson Road Suite 134 Tampa, FL 33625

Make payments in U.S. dollars to: D&H Solutions LLC

The WEB page will have an order form to make ordering easier and we plan to offer credit card ordering in the near future to make payment easier.

Q. Is GENY-1 warranted? A. GENY-1 has a lifetime warranty on both parts and labor. We will repair any GENY-1 board free of charge. This warranty is even transferable to a new owner if you should no longer require the unit. Shipping both to and from D&H Solutions is not included in this warranty and will be the responsibility of those sending us the unit.

Q. What is your e-mail address? A.

I hope I have answered most of your questions. I'm sure there will be others. We welcome all questions, suggestions & comments.

Thanks for your interest.



>I have taken the liberty to include a reply I recently got from Mr Hanson >about his device and his comments abour the lomo 'scopes and Nassen's >condenser... > (I asked him if I could use a laptop pc with his device) > Hi RYB, I don't recommend that SquareOne be used with a laptop. Most laptops with an external earphone jack don't put out a strong enough signal to drive SquareOne, so a preamp is necessary to boost the signal level. The trouble with this is the tremendous amount of RF that is generated by B/R device. The preamp also amplifies the RF and it can end up messing up the signal. Regular PC's don't have this problem because the signal going to the speaker is a higher level, so no preamp is necessary and the RF doesn't bother it. Laptops will work with SquareOne when it is driving the Biotec 2000 because the Biotec doesn't generate RF like the B/R does.

I recommend just buying an old PC... 286, 386, 486, etc. It's better if you can find a PC AT clone and not a proprietary manufacture such as Compaq or Dell. You need one with a speaker that is connected to the motherboard with a thin 4 position connector (outer 2 wires connected), with +5v on one of the leads. Most PC's use this type of connector, but it is better to check first. If you don't have one like this, they can be purchased very cheaply and just use it as a dedicated device.

I furnish a jack/connector assembly that gets mounted in an available back slot plate. It has 2 connectors attached to it. You need to unplug the speaker and plug it into one of the connectors and then plug the other connector back into the motherboard. It basically puts the jack in series between the motherboard and speaker and will cut out the speaker when SquareOne is plugged in.

RifeGen is basically a DOS program, but it will run in a DOS window running in foreground of a windows environment (Windows 3.1X or Windows 95). I don't know if it would run under Linux. I guess it depends on if the tones get routed to the speaker port while running under the Dos enulator.

I don't have a web site up yet, but my brother just took a picture of SquareOne a couple of days ago with his new digital camera, so if you have some way to view a .jgp file, I can upload a picture to you. Maybe I could upload it up to my free Prodigy page if I can figure out how to do it.


Adjusting the duty cycle of a squarewave generator even SLIGHTLY causes drastic changes in the amplitude of both the even and odd harmonics of the signal. In fact, I have found that to suppress all the EVEN harmonics, the duty cycle must be EXACTLY 50%, within a fraction of 1%. Also, ANY distortion of a sine wave creates harmonics. I'm sure that in Rife's day, they certainly didn't have the technology that would be needed to precisely control the harmonic content. Heck, WE can't even do it, unless we implement high-speed digital switching circuitry with crystal-controlled time bases, and even then there's a chance of phase shift and rise/fall time degradation when going through the switching/modulating stages.

As I mentioned in a post some months ago, the slight difference in duty cycle between all our function generators (and CB component tolerance) could very well be a contributing factor in the varying effects between our B/R setups. In fact, I'm SURE of it if it's the harmonics causing the effects. ...Tom


(Voltage input from func generator to CB discussion - when people talk about voltage level on this list, they are usually referring to Vavg, not Vpp, which is what would be measured on a meter on DC setting for a 0 to +V 50% duty cycle square wave. On a square wave, Vpp = 2Vavg. To get Vpp levels, multiply by 2.)

5 volts will distort the wave. you can see this on an O'scope. 1.8 volts will distort the wave too, but only between 300 and 11K. Below 300 and above 11K, the 1.8 volts will bypass the CB and enhance the wave significantly.



From what I can tell, the Kinnaman as modified by Ed Heft is a good choice for a BRG signal generator. Ed has made it programmable with a keypad input and 0-2.5V voltage regulator. It holds 17 (I think) frequencies which are run in order for whatever time chosen.

Only problems with this model I can tell from reading reports are

1) Susceptible to noise. I figure I could overcome this with chokes and such.

2) Goes to 0V output for 12 seconds when changing freqs. This means that the extra "Kinnaman" mod to the CB as described by Bare in his manual must be made (which I made anyway). Otherwise, the tube will go off and may not light back up after the 12 secs is up, and if the tube does not light and the SWR is high (which is certain) and the operator does not notice, components start frying. Also a concern would be SWRs which went south for certain frequencies, and are not noticed. I am now confident that my SWR will not change drastically between frequencies, though.

3) Price. From what I can tell, price is $385 for full up model from Heft, which includes gating, voltage regulator, programmability, and keypad. This is about $100 more than the Ramsey, I think.

4) (forgot to mention in original post) Hard to program. No matter how many cryptic key strokes you make, though, it would become easier with time and IMO worth the trouble.

Even with these concerns, it would certainly be worth it to me to be able to program in the frequency set and not have to manually set it every 3-5 minutes or so. It may also be the solution to those who use long lines which may adversely affect the operation since they don't want to be too close to the tube.

Why don't more people use Kinnamans?


Because it's overpriced, cumbersome, kludgey device that, unfortunately, is the only Thing available for programmable portable use...


I'm using Bob Hanson's SquareOne (excellent device) for my home/research R/B And I'm building up a portable so that I can reach out to those that can't get to Me.. Anyway, I got the manual for the Kinnaman and was I ever disappointed...

I've talked with Bruce Stenulsen urging him to address the need for a better portable Device. He is "on-it" and hopefully will someday make available something worth Using....I just hope I can wait for it but, alas, I may have to buy the Kinnaman anyway...

P.S. I guess I've been spoiled by the features of the SquareOne... grain-of-salt...<G>


I recently worked with another Ramsey, integrating it into a BRG. I don't know how everyone works with these. I am getting close to knowing what I am doing, and it takes me about 20 iterations of component positioning and changing cable lengths to get it where I think it is working well.

Perhaps it was the black-faced palomar in this system that passed a lot of harmonics that made it so tough to build it to perform well. After working an hour or so with it, I broke down and put the transformer in the Ramsey and grounded the case, using a shielded power cord as I did on the last one I made. This was not enough. I also had to make the CB to Ramsey cable as short as possible (about 5") _and_ choke it, otherwise the Ramsey display would kick off or go haywire.

I found one setup where the Ramsey would work with an approx 18" CB to Ramsey unchoked cable and not kick off (as long as I did not touch any metal in the system), but it did not produce a CB tone until I choked it AND turned the Ramsey power up ALL THE WAY. Since leaving it cranked up this high (5Vpp) was unacceptable, I rearranged until I got it right.

Lesson here is, it can appear that your Ramsey is working correctly, but not causing the production of what I think is a powerful wave. A good way to check out if your system is -

Tune to a medium frequency like 2128. You should hear the CB tone. Crank the voltage from the Ramsey all the way up to 5.0Vpp (2.5 VDC on a meter). If the wave looks significantly different (gets focused where it was fuzzy before) or the CB start producing the tone where it was not before, it is not optimal. The system I built with the black-faced palomar produces audible tones down to 100Hz, and the beam stays amazingly focused down to 1Hz, but it does need to be turned up to 3.6Vpp (1.8VDC) to properly modulate at low frequencies (under I suppose 300Hz), even though the beam looks fine without doing so.

It should do it all the time at this frequency level.

It's being shut down by the RF. Use a choke on the power cord into it as close to the box as possible. If it's a thin cord, wrap it through the choke as many times as possible.

Second, keep the CB to Kinnaman cable as short as possible. Since you are using the CB cord and microphone, I would recommend making a CB mike connector to BNC coax cable (RG59). Pinouts are given in the CB mod file in the Rife notes section of my web page.

Third, (I don't think this is possible in an F1B), ground the func generator case, and the rest of the components.

Fourth, try different component positions and short-as-possible coax cables (7-12 inches instead of 18 feet).

If these measures fail to prevent the device from shutting down or going haywire, it is necessary to put a clamshell RF choke on the CB to Kinnaman cable. A number of people do it and get good results. On one system I built, it produced a louder CB tone (and better harmonics) because the cable otherwise had so much interference on it.

Put a fan under it blowing up with the bottom of the case removed. This will provide optimal cooling. Some people get by with merely putting a heat sink on the back of the CB using the small nut and bolt which hold the power transistor which gets hottest (glued to the back of the case).



>Do you have an opinion for the best duty cycle to use on an accurate >function generator that does not drift? 50, 51, or 88%?

Fourier analysis of a variable duty cycle square wave shows that the voltage harmonic amplitudes are given by the expression: Vn=Sin(n*Pi*D)/n where D the duty cycle is defined as the ratio of pulse on time to the period of the waveform, n is the harmonic number, and Pi is 3.14. The expression is normalized so that a 50% duty cycle (D=.5) and n=1 gives a voltage amplitude of unity. The variation of relative power levels with harmonic number and duty cycle can be calculated by squaring the voltage expression. Notice also that the power levels are symmetric about D=0.5. That is, the harmonic power for any n is the same at D=.1 and D=.9.

If you know how to draw the time variation of a sine wave you can easily show how the voltage harmonic amplitudes vary with duty cycle by plotting the total range of duty cycle (0 to1) on the horizontal axis. Then it is seen that V1 varies as a half cycle sine pulse where it is zero at the ends and equal to 1 at D=0.5. The second harmonic V2 has a full cycle. It is zero at the ends and at d=0.5, and +.5 at D=0.25 and -0.5 at D=0.75. The third and higher harmonics are plotted in similar fashion. Because of their sine wave nature the higher harmonic amplitudes will oscillate rapidly with duty cycle. The question of the best duty cycle is difficult to answer. I personally believe that the first or fundamental is the most important. This is based in part on the general range of frequencies that seem to be useful as well as the significant decrease in relative power levels as higher harmonics are considered. For example, the eleventh harmonic has a relative power level 121 times less than the fundamental and the 101 harmonic has a power level 10,000 times less, assuming equal resistive values with frequency. A spectrum analyzer is a remarkable tool for viewing power levels that vary over a wide dynamic range. It can easily view signals whose power differ by 100 million times or 80 dB.

To find out if harmonics are effective at all, a person sensitive to a certain frequency could be tested by switching from square to sine wave operation and noting if they can tell the difference.

I thought this may help someone with this problem.

There are two problems I have found with the F1A or F1B Kinneman unit cutting out.

#1 During startup of the light, the circuit in the F1A would short out and just give a blank display. You would then need to turn off the unit and back on with the power to reset it. Fix is to put a ferrite choke ring 1/4" thich 3/4" ID, 1.25" OD approximately on the BNC line out of the Kinneman. This will block feedback RF into the unit and stop the shorting out. You can use the small ballun ferrite ring with wire off taken out of your tuner (exculding MFJ 962 models) if you have added an external 912 for your balun.

#2 While the light is running, touching the power wire or BNC coax cable wires or the metal back of the F1A would cause the Kinneman to short out and the output would go out and the dashing lines would come across. The fix is to adjust the length of the coax cables between the CB and Amp and or the Amp and Tuner, and or add a length of coax 3ft to 18ft between the Tuner and external 912 balun. I have found that an 8 inch coax was necessary between the Amp and Tuner to fix, with a 3ft between Tuner and 912 and a 9ft between the CB and Amp on one unit. This will be unit specific. I had to set the Amp on the Tuner for the coax to reach.



>From Sat Jun 20 23:26:41 1998

My F1B cutout problems were solved with three steps. Not sure if they were all needed, will indicate. My problems were pretty much as Kent described on the 18th run -- during the 17 before that the unit was well behaved generally, the only thing I noticed was that if the unit were moved, or the power cord touched, it would reset even if nothing else was running! On the 18th run and every run after that it went haywire, resetting after 30 seconds or so. Still not quite sure why but seems to have been RF coming back from the CB while the amp apparently went south (sigh).

I use a 6 foot 52 ohm BNC cable to go from the FG to the CB mic, to which I've grafted a BNC connector instead of the two screws method. Better connection.

Here are the fixes to mine:

1. Ed & Goldie Heft copper-lined the unit with what looks like 0.05" copper sheet. It's not a great job but looks functional. I'm not sure how much difference this makes.

2. Standard Radio Shack square RF choke on the power line coming in to the unit, about 2" before the plug into the FG. The power line picks up a lot of RF and feeds it right into the unit. This change by itself really helped but didn't cure the problem.

3. Replaced the standard 9v 200ma power supply with a 12v 500 ma power supply. The slightly greater power really seems to make the FG much less sensitive to stray signals as you would expect. I think this is really a good fix. The F1B is rated from 5v to 14v input power so 12v should be just fine. You could also drive it off your 12v DC power supply, in that case you'd better put two chokes on the FG power line as lots of interference comes back to the power supply from the CB and amp grounds.

Haven't had to try a choke on the line from the FG to CB.



Folks, Recently I have been having problems with my Kinnaman losing its programing, displaying strange codes, blanking out and changing the program on its own. The problem for this was found to be a High Voltage Constant Ignitor ( 15 kv ) I used during pulsing and lighting the tube. The Kinnaman would malfunction whether it was a attached to the unit or not. A 1' BNC cable was all that was needed to pick up the HV and delete the programing. Seeing as how I also had the unexplained problem before using the HV ignitor; I feel it was caused by the Grill Lighter I once used to excite tube the tube on start up. This problem, using the HV ignitor, has been corrected by a new type wrap that requires no ignitor during pulsing the carrier. It appears to work on every tube but a quartz but, it makes the quartz easier to start and runs lower SWRs in the B/R mode pulsing the FG only. Averaging below 1.2 to 1.35. An attachment of a JPG file will be sent on request of this wrap. Send other type format name for the picture if needed. The Kinnaman is my choice of FG for B/R work. The Lodestar was used until the problem of the HV was found. The Lodestar was not effected by the HV. Tuning of Frequencies was with the unit off. Must be an art to operating one of these things. So far I have not found it. Very good for a backup though. Thought I would pass this along to those of you that have been having unexplainable problems with the Kinnaman programing.



SquareOne is basically a stand alone unit (not a plug in card). It connects to the speaker port of the PC. The reason that I didn't recommend it with laptops before is that most laptops with a speaker jack don't put out a very high drive signal. It isn't sufficient to drive the SquareOne box unless a preamp is added. With a preamp added, it boosts the signal enough, but it also is more likely to pick up stray RF floating around the room making it somewhat unstable.

What this fellow has done is taken the SquareOne circuit board out of the metal box and mounted it in the laptop battery compartment. Then he tapped directly into the speaker drive circuitry where there is a much stronger signal. By tapping directly into the speaker circuitry, the signal there is just like in a standard PC and there is no need for a preamp and RifeGen/SquareOne work beautifully. The Biotec can be driven very nicely with a laptop,SquareOne and preamp because there isn't any RF to mess the signal up. You need to get inside the laptop to get to where the signal is stronger so the RF doesn't interfere for using it with B/R.

I think that he used an AST 386 for his first unit. If I could find a cheap source of laptops, I'd probably do this myself. I know that you are an electronics guy, so you probably wouldn't have too much trouble doing it also. It takes someone who isn't afraid to open up a laptop and start hacking it <G>.



Kinnaman is positive offset square wave. It is not biphasic, so if negative side is being counted and measured, it is just not there with the Kinnaman.



>and Run a Ramsey at 12 vdc...the power supply say 12 vac on it?

The output of the 12 VAC just feeds into a bridge rectifier inside the Ramsey. You can run a Ramsey on 12 VDC; the bridge rectifier will "do the right thing."


Increasing the output voltage level of the FG (or amp) can make a dramatic difference in the performance of a BRG. Where the beam looks weak and pearly, or there is not good modulation at low frequencies (looks fuzzy and not coherent), or the CB (or tube) tones cannot be heard above 1000Hz, cranking the output level up as high as a 0-5V square wave (2.5VDC as measured on a multimeter for a 50% duty cycle) may help a good deal. It seems to depend on the length of the CB to FG cable (and the power of the amp). The shorter it is, or the more interference from the wave, the better the beam looks for increasing voltage levels, to a point.

Some have recommended using as high as a 0-3.8V square wave. Mine works well at up to 0-5V in my current setup, where the CB to FG cable is 18". This is much too long in opinion, but a length that is required for this setup which includes 2 FGs.

When cranking up the voltage, the CB and amp must be well cooled since the main failure mode will be from excess heat, according to Bare. Mine does not get too hot even at these levels - I have 4" fans mounted below the CB and amp plus a fan above the amp. I think it may even run cooler since the SWR is lower.

When using high FG voltages, there may be a problem with clipping and therefore generating less harmonics, especially at higher frequencies where the device seems more efficient. I have not scoped it out or used it enough at these levels in this setup to know. For now, I associate the performance with "the louder the tone the better".

With a high voltage level from the function generator, I can hear the tone as low as 200Hz. Using my "normal" output of 0-1.2VDC, I start hearing it at around 1000Hz. This is with a blue-faced Palomar. In a more recent system I built with a black faced palomar and a very short (4") CB-FG cable, I could hear the tone at 200Hz even with 0-1VDC on the FG (Ramsey.)


I am using the Original Kinnaman, powered from my 13.8 vdc supply and with the voltage reducer removed from the output. Voltage at the mic is approx. 5v. As you might imagine, I have a good strong pulse in the 18" U-tube. I have been running at this voltage for several months with no major problems. Every 5 or 6 sessions I have to clean the jacks with a brass brush because the pulse gets blocked. (I suspect this problem is because I used RCA jacks between the FG and mic.


The adjustable voltage reducer will give the maximum of 5 VDC when turned to full adjustment clockwise.

What are you measuring the voltage with??? A VOM will not be accurate an if you are using the AC range, the best will be 0.707 of the peak. As I have been told, the VOM cannot be fast enough to accurately measure the value. You are not the first to run into this, That honor went to Dr. James Bare back almost 3 years ago. The only way to accurately set it is with an oscilloscope which is what to set it to before shipping.

The unit has a voltage regulator and the program in the E-prom will shut down the unit if the output is not within spec. Its either OK or no output.

You could unsolder the variable resistor, but, unless your really proficient at soldering and desoldering, I'd prefer you send it back to us for the removal if you really need it out. We've had a couple of units with literally many blown components that it was uneconomical to repair. The cost of trouble shooting time was more than the assembly costs plus parts made it a loss.

Hope this helps Ed & Goldie.


> I want maybe 1 - 3 Hz sweep

In this case, the Kinnaman is the cheapest generator I have seen that will perform sweeps. They can be set for each frequency entered. The sweep is called "deviation" (I think it is a sweep, anyway. It may be stepping through them one at a time). It also pulses at a user selectable rate (set at powerup so will pulse (or not) all frequencies in that session). It costs $375US delivered in the states. Main benefit of it is it will run through 19 frequencies automatically. Lots of quirks, but I still recommend it.

Kinnaman works fine for a single frequency in my setup if you set the frequency then keep the hand away from it while the tube is on. There is probably a way to set up or ground the equipment even with a large tube like I have in the system while allowing the user to touch the Kinnaman, but I have not found it.

I have two function generators in my system and when I want to run single frequencies, I use an old Wavetech 288. I noticed them for sale on the net for $1500 used. They don't pulse automatically, but can with external sync. They can be controlled through a 488 port in back (need a 488/232 converter card). They have a knob, keypad, sweep modes, 0.001Hz - 2Mhz generation capable (and will pass 20MHz I think), self-calibration, big (blue) display with scrolling, and lots of other features.

I have experimented once using the Kinnaman to input freqs to the FM input of the Wavetech. I was considering using a "main" disease frequency on the Wavetech (like 2128) while running the other frequencies on the Kinnaman and see if that was effective. It was interesting, but when Kinnaman goes into the 12 second wait state between freqs when running in auto mode, too much RF feeds into BNC-BNC connector (I am guessing) and Kinamman, as usual, goes wacky. I suppose I can choke the BNC-BNC cable or make it shorter (using a 3' now) to see if I could control the wackiness.

> Can I set a sweep function and then adjust the audio knob while its > going ?

There is no knob on the Kinnaman. Keypad only. The Ramsey has a knob and also has the benefit of being able to go to about 60KHz (vs 9999Hz in the Kinnaman), but does not have pulsing or deviation. The case can be grounded and this helps prevent FG from going wacky.

> Do the Kinnamon units have both knob setting and programmable > push button? Do they read to ! Hz or less ?

I assume it will run 1Hz, but I have never looked, nor have I tried to set it lower. I will check tonight.


>> Are there any techies of you out there that can tell me >> what the rise time of a good quality square wave would be.. [snip]

*** I hate to be evasive, but the answer to your question is application dependent. For the B/R, going from 100 nano seconds down to 10 nano seconds rise time would result in a non-measurable improvement in the CB output.


I have now experimented with a number of tubes. I have some idea of what makes my Kinnaman go whacky and shut down. As I thought, it does appear to be a factor of the long tube and power applied.

I have experimented with

Cheb - 18" straight with getter, 18" straight without getter, supertube (30" x 2" diam)

Allred - 26" straight, 24" bubble, 28" bubble, and 24" triple bubble.

All are high pressure tubes. Black face palomar used. All tubes wrapped with my new method (conduit holder electrodes rather than copper sleeves) except now defunct triple bubble. All components choked very well with clamshell or torroid ring chokes, with both clamshell and torroid ring on short signal line from FG to CB.

With either 18" straight tube in the system, the Kinnaman acts fine, I can touch it all day long and it is stable at all power levels of the amp. With the supertube at high power or the 28" bubble at any power, it will usually shut down when I place my hand on the keypad. With the 24" bubble or 26" straight, it will usually shut down on high power, occassionally shut down at medium power, and sometimes shut down at low power. The 24" triple bubble would shut it down at any power level.


After many days and nights of research and testing, I have finally designed a transmitter that produces an output of exactly 11,780,000 Hz. which is the only cancer virus frequency that has ever been found in the notes of the late Dr. Royal Raymond Rife.

I have removed the c. b. transmitter from my Rife/Bare Device, and installed my crystal-controlled 11,780,000 Hz., 5 watt transmitter in its place. The only signal now going into the beam ray tube is Dr. Rife's original cancer virus frequency.

A simple single pole double throw switch could easily be connected from the outputs of both the c. b. transmitter and from my transmitter in order to use the 11,780,000 Hz. signal, or the audio modulated, channel 14 c. b. signal seperately. [A pulsing circuit could also be added to my transmitter if desired.]


I make no medical claims for my transmitter, and it is suggested that, if anyone attempts to duplicate this device, it be used for legal experimental research purposes only, and in strict compliance with any and all FCC rules and regulations. NEVER CONNECT THE OUTPUT OF THIS TRANSMITTER TO AN ANTENNA.

I shall in no way be held liable for any adverse effects produced by the construction and or use of my device. The use of this device is at the sole discression of those wishing to do so. I AM NOT RECOMMENDING ANYTHING. I am only stating that I have now added this transmitter to my Rife/Bare Device, and it appears to be working. It causes the beam ray tube to produce Dr. Rife's original cancer virus frequency which is 11,780,000 Hz. [11.780 MHz.]

>From Thu Oct 22 01:30:02 1998

PLEASE DO NOT USE MY PROGRAM, PCRIFE. It has a serious problem.

It appears that not only does the output frequency become incorrect as the frequency increases, the error is variable and apparently uncorrectable! It turns out that the problem is in the way that Quick Basic crunches the numbers for the speaker port.

Apparently, the code in Quick Basic reads the system clock interrupt, and then does some math on it to determine when to pulse the speaker port. The code apparently must discard any fractional remainder. The result is a rounding error which causes incorrect frequency output. Since it's inherent to Quick Basic, it cannot be corrected by user programming.

For instance, setting any frequency between 2997 and 3005 Hz will produce exactly 3005 Hz for an output. This means that some frequencies are not possible to generate, and makes PCRIFE unusable for Rife/Bare work.

I've tried several things, to no avail. I have concluded the problem is inherent in the Quick Basic code, and cannot be corrected by simple programming. It looks as though I'll have to go back to the drawing board - or at least to the coding sheets and take a different approach. It seems that the specific frequencies I used for testing produced accurate outputs, and so I missed the problem. But, no excuses - I goofed on this one. :(

In the meantime, please don't use the program for Rife/Bare work. I'll post a note when I get a revised version online.




I don't know if I've mentioned this before on the lists, but besides all the other quirks of the Kinnaman, the one that has potentially the greatest impact is the way it will not accept a frequency in the first location as it will in locations 2-19.

If you always leave 728 in the #1 spot, this is irrelevant. But, if you frequently program different ones with the "fast method" it makes a difference.

When entering frequencies, times, deviation into the Kinnaman, you can merely punch in the value, then the +- key to step to the next parameter, the value, the +-, ... then when location is displayed, the up arrow to step to the next frequency. After some practice, it is not that difficult, and I can program in all 19 freqs in about 2 minutes. However, the first frequency will not be accepted when this is done. When the Kinnaman is turned off then back on, it _will_ use the frequency that was last programmed into it in that manner.

What I do to ensure the first frequency is changed is put it in manual mode while the location entry is set to 1, enter the frequency I want for the #1 spot while the generator is on, then hit "E" to enter. Then go to automatic mode to program the rest.


You don't have to do it that way, the "RAM" memory on the Kinneman will remember the last frequency that was programmed into it reguardless of what is showing in the display window. To easily fix this after changes have been made and you are ready to begin the automatic program just go to location one and then +/- to display the first frequency you have in location one and hit "E" as this will then update the "RAM" and you can then start the program with that frequency.

Many - if not most - sound cards have AC coupled inputs, and will not respond properly to square waves. the input coupling capacitor will severely distort the waveform, resulting in incorrect values when the program attempts to analyze the signal. The effect is much worse at low frequencies.


Has anyone looked at the low frequency output of the Ramsey on a scope? when I run my tube at say one cycle per second, the (visual) on/off cycles are not of even length. Moreover, after the "on" (saturated beam) part of the cycle, the power levels fall briefly to zero than return to a slightly higher level although the plasma has a washed out non collimated beam. I suppose that if the generator output is not biased, that is the signal goes negative instead of going to zero volts, that would explain the triefield reading, but does the plasma look different on the negative part of the cycle? I guess the question is, at the risk of asking the obvious, why is there a difference in plasma when the modulation waveform is on one side or the other of ground? Would there likely be a greater effect if the tube actually turned off each cycle? Is this achievable by biasing the generator output and is this easily (sure) accomplishable? Also, when I press the mute switch on the ramsey, the plasma assumes the condition of the (negative?) side of the pulse; the CB is transmitting the carrier wave, I its a question of what; voltage bias of the carrier frequency?

The proximity of my hand to the generator makes a big difference also, creating a larger visual pulse.


Max, You're absolutely correct about the lack of symmetry of the Ramsey's output. I also noticed it when I built mine and put it on the scope. If I remember correctly, one of the potentiometers on the circuit board is to adjust the symmetry of the square wave.



Kinnaman "codes" for inputting gating rate:

125 for Kinnaman is 4 Hz 100 for Kinnaman is 5 Hz 80 for the Kinnaman is aproximately 6 Hz. 50 for Kinnaman is 10 Hz


A new programable frequency generator has been designed specially for Rife experimenters. The output frequency is very accurate with a maximum error of 0.003% of the displayed frequency. The frequency range covered is from 1 to 32000 Hz in 1 Hz steps. The generator will store up to forty frequencies and durations which can be arranged in four banks. It has an output gating function which can be selected for each frequency individually. There is also a frequency sweep mode for scanning a frequency range.

>Great! Something I have been looking for is a portable programmable >function generator that holds more than 19 freqs. > >What are the dimensions?

The ProFreGen is very compact, dimensions are:

3.6 in. (91mm) W 6.2 in. (158mm) D 1.2 in. (30mm) H > > >How does the sweep work? Can you set a range of, say, 2000-2200hz >at 10 seconds apiece at each 1hz (or other) freq, or would you have to >break it up into 40 freqs?

Select a start frequency eg. 2000Hz and an end frequency eg. 2200Hz and a dwell period which can be from 1 to 120 seconds. The output will start at 2000Hz and increase by 1Hz after every dwell period. When it reaches the end frequency it starts again at the start frequency.

>What do you mean by 4 banks? 10 freqs per bank? Do you have >a programming manual you could post to your site? > The banks are designed to provide flexibility when programming the frequencies. There are four 'banks' or 'programs' A,B,C and D. The start number and end number are selected for each program. These can be from 1 to 40. Programs can overlap so that frequencies are used in more than one program. eg. Program A: 1 to 15 Program B: 10 to 20 Program C: 21 to 30 Program D: 31 to 40 In this example, if de-tox freqs. are programmed in nos. 10 to 15 then they will be used by both programs A and B.

I will update the web page in the next few days so that it answers all the questions I have received.

Ralph is quite correct in describing how a PC generates the sound. The reason that it increments in steps at the higher frequencies is due to the fact that the TIMER chip uses a 16 bit divisor to calculate the frequency. I wish that they had used a 24 or 32 bit divisor. Then accuracy would be far better at the higher frequencies.

Notice from Ralph's example that the frequency error is always in the positive direction and never in the negative direction. What I have done in RifeGen is to include an algorithm which changes the point at which it jumps so that it will have both positive and negative error direction. This has the effect of reducing the maximum error by approximately 50%.

Since most of the MOR frequencies are less than 3000 hz, the potential error is generally less than 3 hz. The low frequencies are extremely accurate. If the MOR frequencies for a given pathogen follow a bell shaped curve (as commonly thought), then computer generated square waves should be adequate.

Here are some desired vs actual frequencies measure with a Fluke 8060A digital meter while running RifeGen/SquareOne:

Desired Actual measured .185 .18500000 (calc) 1 1.00000 (calc) 12 12.000 20 20.015 72 72.00 95 94.99 120 119.99 125 124.99 304 303.0 444 443.0 464 463.0 664 663.2 760 758.9 727 726.1 787 785.9 800 799.1 802 801.2 880 879.2 1550 1549.4 1865 1864.1 2008 2008 2128 2127 5000 4992 6000 5996 10000 10025

As you can see the higher frequencies have the greater error.

I hope that this helps.

Best of Health,



Hi All - After 19 months of effort and many unsuccessful attempts to make the "perfect" programmable, we have our newest model available which I will say is "almost" perfect. This unit is engineered specific for RifeBare Systems but may well work on other devices where absolute control is required.

Has 20 programmable banks, variable pulse (gate), etc. etc Won't crash with RF buildup. Guaranteed! For details on the "Hammerhead" .....(price - picture - specs) goto:

Thanks Don Tunney


To answer your Speaker-1 FAQ's, here are the specs:

1. It will run in any old P/C, XT or AT, DOS ver-2, and up. 2. There are an unlimited number of MS-DOS files. 3. Each file contains sixteen pages. 4. Each page contains sixteen lines. 5. Each line has the following functions:

Set Freq. required freq, from 18.21Hz to 62,799Hz

Run Freq. actual freq, rounded up or down, due to the p/c hardware limitations, at the higher frequency settings.

Run Time. from 0.1secs to 999.9secs. (17mins)

Pulse Mode from 0.05secs to 99.95secs. (20Hz max)

Swing Mode. from 0.1% to 100.0% of th Set Freq, at a step rate of from 0.05secs to 99.95secs.

Sweep Mode. adds from 0.01Hz to the Set Freq, at a step rate of from 0.05secs to 99.95secs, for from 1 to 9999 steps.

Shape. the programmable duty cycle is not used, due to the p/c hardware limitations.

Being able to change the Shape, or duty cycle of the square wave is very important to the correct functioning of the Rife/Bare system, let me explain:

For those of you that have access to a second CB, turn it on in close proximity to the R/B system, set to channel 14 with the squelch open and volume up. Do not transmit as there is no antenna. Run your R/B system with the following:

Set a freq of 2.00Hz and run, you should hear the clicks through the second CB. Are there 2 or 4 per second?

For those of you with a Geny-1 or Geny-2, try the following:

Set Freq 5.00Hz Timer 10.0secs Shape 50% Set Freq 10.00Hz Timer 10.0secs Shape 99%

Notice that the first ten seconds sounds a lot like the second ten seconds? Now try the following:

Set Freq 5.00Hz Timer 10.0secs Shape 99% Set Freq 10.00Hz Timer 10.0secs Shape 99%

Notice that the first ten seconds sounds like half the frequency of the second ten seconds?

Now repeat the tests with 50.00Hz and 100.00Hz, and 100.00Hz and 200.00Hz.

From these simple tests you should have noticed that for frequencies below 200Hz, the CB can not follow the frequency with a Shape, or duty cycle of 50%, the modulation envelope was not designed to do it. Tom Young's special mods may fix this problem.

For those of you with oscilloscopes, twist about 20 turns of wire around the coax between the linear amp and the antenna tuner unit, clip the probes to each end of the wire, and measure for depth and cleanness of modulation. There should be no ringing, or false pulses of the plasma tube. Try these tests and also experiment with other shapes and frequencies. If possible, try adjusting the square wave voltage during the tests.

My system was built from James Bare's book, using a modified, (cut D14), Uniden Pro 510XL and I found the best CB modulation with the following:

a Shape of 90% for freqs from 200.00Hz to 100.00Hz a Shape of 99% for freqs upto 100.00Hz.

I hope this information is of use to you all, stay well.


I was able to study the ProFreGen at the Rife Conference, and was able to obtain one. There are two models. One is mainly a frequency source for Bare and similar equipment. The other one ( which I got) also puts out plenty of voltage for use as a pad device up to 30,000 Hz.. It also can be used as a frequency counter. It stores 40 frequencies in 4 programs. It has sweep capability. It also appears to put out enough voltage for use as a Beck blood cleaner. The unit requires 12 VDC power.

It is uneffected by the output of R/B or EMEM2/3 type devices. I have powered an EMEM3 with one for the purpose of running a sweep. The EMEM3 puts out a bit more power when the internal 555 circuit is used due to the longer duty cycle. The ProFreGen also has an adjustment for the output voltage when used in the R/B mode. Dick


Hello Rifers,

I have read through the archives of the rife list and had not found a program that could generate a nice square wave with a programmable duty cycle and a programmable sweep of frequencies through my Notebook and soundcard. So I went out to find a program that could do this. Here are my findings:

* - A rifer mentioned that an update to this program can generate square waves with a programmable duration. ie, run the executable with pcgen143 wave3.lst, placing entries of <freq> <duration> in this file and it will run. I would like to investigate this further if I could get a copy of the RIFE modified version of the software.

* - provide a programmable sweep rate, but no square waves :(. Good news is that it is free and has source code come with the zip file if anyone wants to go ahead and modify it to do this.

* Goldwave 3.22 and Cooledit 96. These two provided the ideal solution. Goldwave has an expression evaluator, so I came up with two formulas to do what I want:

- Square wave with programmable duty cycle

((int(2*t*start_freq)%2)*(int((2*t*start_freq)-(((1-duty_cycle)/2)* (int(2*t*start_freq)%2)))%2)*(int((2*t*start_freq)+(((1-duty_cycle)/2)* (int(2*t*start_freq)%2))%2))*2)-1

- Square wave with programmable duty cycle and linear sweep from start_freq to end_freq.

((int(2*t*((((end_freq-start_freq)/t_total)*t) + start_freq))%2)*(int((2*t*((((end_freq-start_freq)/t_total)*t) + start_freq))-(((1-duty_cycle)/2))*(int(2*t*((((end_freq-start_freq)/t_total)*t) + start_freq))%2)))%2)*(int((2*t*((((end_freq-start_freq)/t_total)*t) + start_freq))+(((1-duty_cycle)/2))*(int(2*t*((((end_freq-start_freq)/t_total)*t) + start_freq))%2))%2))*2)-1

where: * t=time, Goldwave has this as the variable x-axis. * start_freq=start frequency, eg: 480 * end_freq=end frequency, eg: 582 * duty_cycle= % of square wave cycle to cycle, eg:enter 0.1 for 10% * t_total=total duration of the sample, eg: 120 for 2 minutes

The easiest way it to cut and paste the formulas above and replace the desired values for the strings into the formula. NOTE: The t (time) variable must NOT be substituted for a value.

Be warned though, the calculations themselves take a while. On my Pentium 166, it took 30 mins to calculate a 2 minute sweep at 44Khz. I use this sampling frequency to obtain the high harmonics necessary for a square wave. Once done, I save the file, a 15 second file is ~1mb. A 4minute file about 20mb.

The Advanced Cooledit Pro can help if you have a slow PC. You could generate a 10second sample, then use the Stretch function (maintaining pitch) to make the sample longer. It can also ramp the sample at the starting and ending so you don't get a massive jolt at these points when looping stops then starts.

Once I've done these, I put together a playlist using Cooledit 96 of my favorite frequencies, the number of times to loop each one and the order that I like. When I set this to play, I can read, watch TV or do any other sitting activity while applying the desired frequencies.

The downside of this solution is a bit of mucking around, needs some decent CPU capability and hardrive space, but once that is done, it works well and I have a lot of flexibility to alter the waveform.

I would like to hear from other rifers on the best shape of waveform so that it enters the body as a squarewave. Somewhere it said that the body is like a capacitor, so the wave gets distorted by the body. If someone can describe the best waveform, I will endeavour to convert this to a formula for entry into Goldwave.

To good health,



To stabilize the Kinnaman is easy. Cut out a sheet of aluminum that the Kinnaman can be strapped or velcro'd to. Then attach a wire from one of the grounds ..say the side of the CB and the other to the plate. Should settle right down. Another trick is to replace most of the power wire from the transformer with shielded microphone cable from Radio Shack. I've found the RF getting into this line is the big culprit in the Kinnamans instability.

I run a Model C Kinnaman at over 300 watts now and have little to no problems with it, as long as I have it on a ground plane.


============================= I have been running some tests to see if the F-Scan unit can be integrated with an R/B. I've found that it can. Here is how to set it up. First get a clam shell type RF choke from Radio Shack and wrap it around the power wire to the F-Scan. I place it so that it is just before the on/off switch, and wrap about three turns of the wire through each half of the RF choke before closing it. Without the RF choke the system gets a little sensitive and may work a bit erratically. You can do this to a Kinnaman unit to help stabilze it as well. There are two output jacks on the F-Scan. The best is to use output jack # 1. This is the jack that is used for the Clark output and also for scanning purposes. Flip the switch nearest the #1 output jack downward so that the unit will output square waves. The other two switches should be up. The second switch can be up or down, down drops the output to 1 volt, but the unit seems to run fine with the switch up at 10 V. You can use output jack # 2. To do so set the output knob to about 25. You can move the switch nearest the output knob up or down as you wish. I couldn't find that it makes any difference if you do. This switch shifts the square wave output to either positive offset or balanced. At frequencies below 100 Hz, it helps to turn the output up to about a setting of 50. If you use the Clark output jack ( #1 ) the unit will work fine below 100 Hz as is.

If the F-Scan is too close to the R/B when it is operating, you the operator will be too close to the tube and pick up a lot of RF. As you try to press the key pads on the unit, the RF in you will destabilize the unit. It is best to use a Pencil with a rubber eraser to press the key pad if you are really close to the tube. Use the eraser end of course on the key pad. Once the unit is running and left alone it works fine. I've done scans and then output the frequencies through my R/B and the unit performed flawlessly. No problems at all were noted. So to summize - Use output # 1 , first switch down other two up. To use output #2 set output to 25, third switch can be up or down. I like the way the unit works with the third switch up. The other two switches are up. Below 100 Hz increase output to 50. With my Uniden 66XL I was able to get a very clean output to about 14K, above that power dropped off some. By 40 K the CB shut down and didn't seem to be passing anything.

The use of the R/B, U tube, Argon, 6.5 Torr, with CAFL freqs at 3 minutes each. SWR 1.8 to 2.0. Watts, 50 to 60. Distance from tube, 4 to 5 feet. Gating or pulsing was set to 4Hz. Cataract freqs: 1830, 1600, 9999, 1552, 2010,1335, 496, 400, 160, 1654, 2187, 2195,2203, 2211, 728, 464, 784, 880. At 3 min each that is 54 minutes. Significant progress in the reduction of cataracts was accomplished in one to two weeks. Application of the protocol requires repetitive exposures at 3 minutes each every day. Volunteer reoported that the reduction of wiping glasses was down to just several times a day to occasionally. Blurred vision has been reduced about 90%. Time span, one week. The use of EMEM 3 device was also effective. The EMEM 3 unit uses a straight Phanotron tube, but it does not have a radio. Both Argon, 6.5 Torr and Helium, 75 Torr, are effective. Standard ball type Phanotron tube was not used. Frequency generators used were Kinnaman, ver 1C, and ProFreGen, from UK, Bob Haining, for the R/B. The Kinnaman does not work with an EMEM type device. The ProFreGen works with both the R/B and the EMEM 3. Results vary with each volunteer and that may be due to the age of the cataracts or other contributing factors. It is recommended that the normal exposure to antibiotic freqs be conducted to reduce contributory factors. Volunteers did not use supplements. Good diets were in order. It may be that the use of supplements would enhance the results and even reduce the time required. ==========================

In working with some frequency sets that were produced by the F-Scan on myself, I found one that opened mine and my wife's sinuses rather well: 1395 Ran this for 5 minutes then 160 for 5 minutes (which has always helped her sinuses and sinus headaches), and back to 1395 for another 5 minutes. It completely drained one side of her problem sinuses, and started to relieve the other side. Initially it physically drained mine and I had to grab some kleenex. Second time it just opened up a stuffed nose.

One cps higher had a negative effect on my wife and she had me stop running it. Did not try a lower cps.

Other frequencies that worked on me were: 952 and 942 Others on the list had some problems with 952, so be careful. But all the above frequencies work well on myself.

Take care, Bob D.


We use the Rifetech units and have had 100% success with the following set run at 180 seconds @ 50% shape (for fall 2000 cold and flu) 20, 26, 48, 60, 72, 95, 125, 180, 300, 444, 522, 555, 727, 787, 802, 880, 1500, 1550, 1865, 2050, 2720, 4868, 5000, 6989, 7001, 7009, 7702, 7762, 7767, 10000 God bless ===================== 5 days ago a delightful lady came to see me with a huge worry on her mind. She is in her mid 40's. Just been to the optometrist and her eye ball pressure had gone from 16-left/16-right, 3 years ago to 26-left/26-right. The optometrist had given her the run-down about Glaucoma and she was really worried. Last Wednesday I ran the Glaucoma freqs with her sitting about 5 feet away from the tube. 1600, 880, 787, 727 all for 5 minutes each. She didn't feel anything from the treatment. Next day (Thursday) she had her eye's tested again. Now 22-left/24-right. Still high but a little improved, the optometrist called for a second opinion. An appointment was scheduled for Monday (today). On Friday I ran the Glaucoma freqs again for 5 minutes each. Still no noticeable hits. After reading a little about Glaucoma and blood sugar levels on Saturady I ran the Glaucoma freqs for a third time on her on Sunday (3 minutes each) and the Diabetes freqs for 3 minutes each except for where Turf's instruction said longer on specific freqs. 20, 35, 465, 6.8, 440, 484, 660, 727, 787, 800, 803, 880, 1850, 2008, 2127, 2000, 2003, 2013, 2050, 2080, 5000 I did not repeat the 880, 787 and 727 in the Diabetes as these were in the Glaucoma. Again, no noticeable hits or detox effects. My client came singing and dancing to see me this afternoon with the news that her second opinion readings were back to normal 15-left/16-right. The Optometrist had run numerous checks on two different machines and the readings were valid - he even retested the first instument that his associate had origionally used on her, it also read 15-left/16-right. The Optometrist was really mystified. She is now going to be re-checked each month for the next 6 months to check her progress. We agreeded not to Rife her again to see how she goes. Although she is now going to get her blood sugar levels checked with her MD. Results like this just blow me away. If you could have seen the light in this ladies eyes and the bounce in her step as she came up the stairs to see me. Ken U. ===============

Only if your function generator is capable of 80% to 95% duty cycle (or whatever it is that you get out of the given 555 timer circuit).

Probably the best one, IMHO, is Fred Walter's program FreqGen, the latest version of which is available at will let you generate specific lists of frequencies, run sweeps, scans, set dwell time, pulse the freqs, set different freqs in each sound card channel, and set the phase between channels.I use it with my signal processor to obtain variable pulse width waveforms. There is also a slightly earlier release archive of FreqGen with instructions available on my web site.

The sound card in a computer generates very good sine waves, but very poor square waves, so you need to square the signal, using something like my signal processor.For more information, on this, please see my web site at

Go to the Rife Projects page where you will find an index page listing in chronological order the various projects I have been working on. Look for my Signal Slicer SSQ-2 and my SSQ-2P phase processor.Either one will work fine to generate good square waves from sine wave signals.




This issue of frequency generation is a perennial one that keeps coming back - I think some definitive clarification is in order, I'll address each point separately and hopefully lay this to rest once and for all!

This is basicaly true but can be slightly misleading in that sound cards do not suffer from the same problem in the same way as the PC speaker - this needs some explaining.Firstly let me address the speaker issue.The PC speaker is NOT capable of producing accurate frequencies under ANY circumstances, no matter what anyone claims (there are some people writing software and making claims to that effect).The reason why it cannot is a hardware issue and nothing to do with software.

The PC speaker is connected directly to the output of a timer chip in the PC.Basically, the timer can switch the speaker output high or low within certain time intervals.This will create a square wave by setting the output low for a certain time and then setting it high for the same time, then back to low again etc.

However the timing is limited to the timing resolution of the timer chip itself.The timer in the PC is based on very old technology and for compatibility is run with a master timing reference clock of around 1.8 Mhz (this is incredibly slow by modern standards).What this means in practice is that the timing resolution of the chip cannot possibly be better than (1/1.8Mhz = 0.55 microseconds).This sounds quite good, but is actually very poor.What it actually means is that the output wave can only be timed in integer multiples (whole numbers not fractions) of 0.55 microsecond steps.

Now when you go from one frequency to another each successive frequency will differ from the last by a certain timing fraction - there comes a point as the frequency increases where the step from one frequency to the next is less than the timing resolution of the speaker timer chip - when this happens the frequency becomes inaccurate.In the case of a PC (ALL PC's!) this "break point" occurs at 1341 Hz for 1 Hz steps.In other words the PC speaker output will give a frequency no more than 1Hz out for any frequency below 1341 Hz.Above that point it becomes inaccurate and what you ask for is not what you get.

The output from the speaker driver circuitry is a square wave but if the speaker is left connected it won't stay anywhere near square.If the speaker is removed the wave will be better but it will degrade in any connecting wire. So a good square wave is near impossible from the speaker output without extra circuitry.

Now to address the issue of sound cards.Sound cards can create waves by digital sampling.An analog signal is synthesized by lots of samples.This can create accurate SINE waves up to one half the sampling rate of the signal.

In the case of modern sound cards the highest sampling rate is 44 Khz so it can reproduce sine waves accurately up to 22Khz (in theory). In practice however, some special filtering is needed to avoid what is called aliasing noise and not all sound cards have it.

But a sound card cannot synthesize an accurate SQUARE wave for the same reason as the speaker circuit - the timing resolution of the sampling is the limiting factor - in the case of the speaker the timing resolution was (1/1.8 Mhz=0.55 microseconds).In the case of a sound card the timing resolution is (1/44Khz=22.7 microseconds) which is much WORSE than even the speaker!In the case of a sound card creating square waves the limiting frequency for 1Hz accuracy is approx 209 Hz!So a sound card cannot produce accurate square waves (to within 1Hz that is) above 209Hz!

However, the SINE wave output is perfect up to around 20 Khz IF a very good low pass filter (with sharp cut off above 20Khz) is applied through external circuitry.An external circuit to make a square wave from this sine will produce accurate square waves in the audio range.

Whether perfect square waves are necessary or not for Rife work is a separate issue.As I have explained on my web site the original Rife machines and the Hoyland variants used pure sine waves for modulation, NOT square waves and they worked just fine - and Rife's original principle was that a single pure frequency could kill pathogens.So it's not correct to say that ONLY square waves will have beneficial effects.However in practice most people find that square waves seem to work better for pad type devices.

> > This subject is discussed briefly at > (although this does not mean I > specifically recommend that product).

This web site is a very bad example unfortunately!The whole site is full of technobabble and pseudoscience and the page in question contains very dubious material.On that page is a claim that voltages below 12v cannot produce perfect square waves - this is complete rubbish because the wave shape has nothing to do with the final voltage, you can produce perfect square waves at any voltage within the limitations of the actual circuitry used.

Also the oscillosope trace shown on the site is faked or the oscilloscope is faulty!If you look at it carefully the whole wave is sloping to the right - on the falling edge of the wave, the trace actually goes slightly BACKWARD along the x-axis - this is impossible on a normally connected oscillocope - unless it's faulty!What this would mean is that the oscilloscope was capable of going backward in time which is ridiculous!

Also this site promotes CD's to produce Rife frequencies.CD's work the same way as sound cards, they cannot produce accurate square waves above 209 Hz and also as Ralph Hartwell has pointed out in the past, the timing of commercial CD players can drift significantly.

As always, I strongly recommend that people research the technicalities of any product before believing advertising claims - many in the Rife game are quite ridiculous if not outright cons.

I commend your efforts to produce a definitive site with rea information about various devices, it's badly needed.

Agreed, this is absolutely correct.Not only that but PC's generate all kinds of high and low frequency electrical noise which will appear in the output signals.

Also agreed - a PC doesn't even come close.That's not to say that a PC can't be useful in simple home applications but as always extra circuitry is required to clean up and/or shape the signals.

This is not strictly true.A DDS (direct digital synthesis) chip which can produce very accurate frequencies is not expensive (about $10) but such a chip won't work alone, it needs supporting circuitry to keep the output clean.The required quality and complexity of the supporting circuitry and the whole build quality of the machine is much more expensive and critical than the frequency chip itself, skimping on this circuitry will give very poor results no matter how good the chip is.Such circuitry need not be expensive but the design effort is greater.

The price of some commercial machines bears no relation to the quality of the circuitry.An example of this is the F-scan which is ridiculously overpriced and contains extremely poor quality circuitry - if anyone is in any doubt about this, set an F-scan to sine wave output and look at the waveform produced on an oscilloscope, prepare to be horrified! Also check the frequency accuracy with a calibrated frequency counter - you will be surprised there too.

It has a chip capable of producing clean, accurate frequencies but lacks the supporting circuitry to actually make it work properly. The output of a cheap PC sound card on sine wave is actually better than the output of an F-scan.

So in a nutshell, price is no guide to quality and there is little justification in terms of actual circuitry for the prices of many of the machines out there today.

Seconded - ALWAYS get someone to check any device on real test equipment like an oscilloscope and frequency counter.

Also agreed.In my own research I've found time and again that certain conditions will cause pathogens to GROW - the signals will stimulate rather than kill them - others will wipe them out.It's not just a factor of frequency in general, but in most modern machines frequency is a critical factor that should not be ignored. There is a very fine line between between stimulation and mortality and even if you know what you're doing, caution is always necessary.

Finally, just as a separate issue.Windows 2000 (and XP) are based on Windows NT.The technology is different than the one used in Windows 98, ME and earlier ones.Basically, the NT core contains mechanisms to protect I/O devices from being accessed directly by user programs (it's possible but complicated).A program that accesses direct I/O (like the PC speaker) on an earlier platform will NOT work on NT, 2000 or XP unless it is designed to specifically access specialised API's in those operating systems or has a full custom device driver compliant to NT core standards.The program will run but may not give any actual output - or may bomb out with protection error messages.

I went to and downloaded the F100 software.All I can say is *excellent*.This is exactly what I have been wanting in a rife function generator interface. Of course, I cannot comment on the hardware since I have not used it, but from the specs it appears that it should be just as competent hardware-wise.

Once the software comes up, there is a blank screen with three buttons, Run, Hold, and Stop. All you do is start entering the runtime parameters and frequencies.See the F100 guide.txt for a list of them.

Here's an example of programming the Abdominal Inflammation set from the CAFL, using the typical 3 minutes (180sec) per frequency at a 1Hz, 50% duty cycle gate rate.# indicates an optional comment line.

# Abdominal Inflammation dwell 180 pulse 1 50 380, 1.2, 2720, 2489, 2170, 1800, 1600, 1550, 802, 880, 832, 787, 776, 727, 465, 444, 1865, 146, 125, 95, 72, 20, 450, 440, 428, 660

THAT'S IT!Enter the first two lines to define the dwell and pulse parameters (or have them in a template,) then cut and paste the desired set from the CAFL or other frequency list.It took me less than 1 minute to create that set!Commas are not necessary between the frequencies, and they can be in a column instead of rows.

Here's something just as good.Set up a scan from 2000-2600Hz at 10 seconds per 1 Hz (with 4Hz gating)

# Scan 2000-2600 10sec/Hz dwell 10 pulse 4 50 sweep 2000 2600 1

That also took less than a minute.

There are other interesting features like "fuzz" (sweep up and down about the set frequency), goto (create loops in a set), and vduty, which linearly extrapolates the duty cycle based on the frequency.

There are batch mode commands for running the sets (with or without the GUI) so that you can have a bunch of icons in a folder, each one a different frequency set.Click and run.

What a giant leap forward in function generator interfaces!


I've recently developed a high speed gated pulser circuit using an SCR and a minimum of parts. Produces a positive offset on cycle of the gated frequency. Using this today for the first time I ran up as high as 200 Hz for a gate rate. Not the typical 2 to 6 hz we have been using . The idea for the high speed gate came from Rife using a 60 Hz gate on his device. The purpose of the gate is to produce entrainment between two objects of the same frequency.

A quote I found on Entrainment is:

> Entrainment is defined as the tendency for two oscillating bodies to lock >into >phase so that they vibrate in harmony. It is also defined as a >synchronization >of two or more rhythmic cycles. The principle of >entrainment is universal, >appearing in chemistry, pharmacology, biology, >medicine, psychology, sociology, >astronomy, architecture and more.

In other words - if one targets an area of the body, or infectious organism with a frequency that it is resonantto, that frequency may be ineffective. The reason is this....The area of the body, or infectious organism may not be entrained to the frequency. That is, it is has a different beat than that of the music (frequency ) being played. The two are not dancing to the same music!If the external frequencies entrainment rate lacks adequate intensity,or adequate rate,there will be no entrainment to the external frequency ! An analogy to this would be performing a popular dance song at too slow a beat. The song and instruments would be in tune, but the beat would be too slow to make anyone want to dance. Same would occur if the music was played at the correct tempo, but was played so softly no one could hear or "feel" the beat.

Starting about 16 Hz some intense effects from the frequencies were noted. By 60 Hz effects were very intense. I only ran at 200 hz for a short amount of time due to the intensity of entrainment effect. One must match the gate rate to the audio frequency. Too fast a gate for the frequency produces no effects.

Did a bit of looking about the web, and it seems that various organs in the body may exhibit entrainmentof the cells that make up the organ.This does not necessarily cause entrainment of the rest of the bodies organs to the one rhythm. Many organs show entrainment to various light/circadian rhythms. The object may be to force the organ or infectious organism to accept the new entrainment, and thus make allow for the full transfer of energy from the resonant frequency.

Will report as more work is done. Will post diagram to produce the pulser once am convinced that this is safe. Right now am running it off two frequency generators Will make up a small 555 circuit to interface as the pulse rate oscillator. About 30 dollars in parts, 1/2 of which is the cost of the BNC cables. Should work with electrode units too.

Could you tell me exactly what is needed to turn a function generator, such as one of those in your post, into a pad type (Rife) frequency generator to "zap" using the various frequencies in the CAFL list, as an example. I have a Hulda Clark "zapper" but it is restricted to only a few frequencies used to kill parasites, but I really like the Velcro bands that are used for the conduction, strap them on and go on with other work. I would like to adapt them to a more flexible frequency generator like the ProGen 4050, which I think is a super buy considering its upgrade potential. However, for now and for many of my friends who are looking for an inexpensive FG unit, what does it take to make one of these "off-the-shelf" function generators a pad type frequency generator?


Steve, I use my Geny-2 ( that I use for a R/B machine that I put together) connected to a 40 Watt PA amplifier from radio shack. I use the sticky pads that are used with the "tens" units that the Dr's. use, you can use any kind of frequencydevice with this type of unit. Works GREAT!! Lee Elder
