Guest guest Posted August 20, 2006 Report Share Posted August 20, 2006 Hi rpautrey2, Why would you say that? This just happens to use a good freq generator chip. From an experienced tech's point of view it looks good to me. One of the nicer kits I've seen. Most don't even have an enclosure, let alone silk screened panels. The B & K 4011 you mentioned tends to drift and certainly doesn't go anywhere near 20MHz. Most of the test equipment on ebay " is " junk in that the people selling it don't even know how (or care) to test it out. They usually say something like " everything lights up " .

Guest guest Posted August 20, 2006 Report Share Posted August 20, 2006 Hi Bil, Look up the Elenco FG500. A rock solid little analogue function generator that can be foun at under $50 online at many dealers. As far as p.p. voltage is concerned, even 3v is more than adequate. " It's not the power, it's the precision. " I think this one is 20v p.p., I may be wrondg Dr. Ian MacLeod, Ph.D. Bil Green wrote: Here's a 20MHz frequency generator kit at an amazingly low price http://webtronics.stores.yahoo.net/kit10120fung.html It includes the enclosure (with labeled front and rear panels) The output is only 10VPP AC. To use as a pad device you could apply +/- 9V (two 9V batteries for instance) or more (instead of +/- 5V) to the output stage when building this. There is an output level control, which also allow you to adjust for positive offset.

Guest guest Posted August 21, 2006 Report Share Posted August 21, 2006 Hi rpautrey2, As I mentioned in the first e-mail this voltage can be greatly increased. The output of most function generators is only 15VPP. A small amp is need to boost the signal unless large pads are used. BTW, your body resistance is much higher than 50 ohms. So the output voltage will be closer to 10VPP. 50 ohms drags the voltage way down. This kit is for people that can't afford a 20MHz function generator (they ain't cheep).

When giving the voltage output specification for a function generator the norm is to give P-P and RMS voltage within a specific frequency range, with a specific type of waveform( example - Sine, Square, Triangle, Pulsed, etc.) with a specific output impedance and into a certain load( open circuit,50 ohms, 500 ohms, etc.) The output of the device is 2V( not 10V or 20V) P-P and up to 20MHz in 3 ranges with coarse/fine variable freq. control. That is not very good adjustability/resolution. There is no frequency counter and it is a kit. That is all we really know about the unit.

From what I have read about his equipment from the late 1940's, it may have never worked. 9) Read Clinical Electrotherapy by and Currier if you want to see what really works. This is a mainstream medical textbook and yes, they do cure infections with electrotherapy. 10) I own a BK 4011A and it does drift( readjust ), and you have to warm it up for about 10 minutes to become a lot more stable, but it works for what I use it for every time. It also has a frequency counter, a whole lot more ranges and adjustment, 20V P-P with an open circuit (10V P-P with a sine/square/triangle wave into 50 ohms), and I didn't have to build it. 11) Bob Beck duplicated the Rife/Crane Pad device ( modified Eico 377/Heathkit)with a more modern BK 3011 and the addition of a stepup transformer for higher output. I am sure it was no more stable and drifted just as much as the BK 4011A. 11) If you are using squrewaves with full positve dc offset as Hulda suggests, and microbes have a bandwidth, readjusting frequencies because of drift may be beneficial. 12) Low voltage does have it's place in electotherapy. Iontopheresis and tissue regeneration are two examples. Becker,M.D. has demonstrated this. 13) My point is this, the BK has it's applications in electrotherapy as do other devices, but sick people should not have to weed through fraud, ineffectiveness, quackery, placebo effects, poor advice, misunderstandings, misdirection, incompatability, complications, etc., etc., etc. Autrey Quote Link to comment Share on other sites More sharing options...

Guest guest Posted August 22, 2006 Report Share Posted August 22, 2006 Wow! Impressive Resume' I can only say that it doesn't require a huge resume' nor does it necessitate a lengthy list of qualifications in order for one to become an efficient and effective researcher in this field. I will not take this statement apart, nor will I dissect and destroy the inaccuracies in application of ideas, that is not productive. Go forth and experiment folks ... you are all doing a great job! My team and I have gleaned so much valuable information and made valuable contacts (we have even hired two of you) in our research.
