[South Florida DX Association] Hams at work- Interesting Video

>   Hi Norm,
> Kanzius is definitely on to something. Also, its the best use of the 
> 27 MHz band (former 11m band) that I can think of!

> Back in 1979-80 I was involved with Q on a similar project with the VA 
> hospitals in Miami and Tampa.It was during the days of de-bunking the 
> RF scares. We actually built a microwave diathermy applicator and 
> controller for cancer research. It was controlled by an Apple-II 
> computer (one of the first personal computers that I ever used). The 
> motivation was to prove that RF can be healthy also. It was the 
> application of microwave energy using focused beam and controlled 
> based on many implanted thermal probes. There are multi million dollar 
> versions of it available, but the prognosis for that approach is poor. 
> To target the cancer you must be able to focus the beam, and that 
> means going up in frequency. But to be able to penetrate well into 
> tissue you need to go down in frequency. Dillema!  We used the 915 MHz 
> ISM band for the tests (same as commercial microwave ovens). Cancer 
> cells are slightly more prone to die than healthy cells ... they die 
> at a degree or so lower than healthy tissue, and since blood irrigates 
> them poorly, the application of RF tends to work, somewhat. Kanzius

> The Kanzius breakthru is (1) he's discovered a way to make cancer 
> cells more vulnerable by injection of RF lossy materials [one can ask, 
> why not just inject a powerful drug into the cell mass, and yes that 
> is done too], and (2) by making the cancer cells way more "RF-lossy" 
> than healthy cells he can just blast the whole body with a uniform, 
> unfocused RF (27 MHz ISM frequency -- 11 m wavelength! There is a 
> better ISM frequency: 13.68 MHz). The lossy parts will heat up way 
> faster than the healthy parts, and die off at a faster rate than 
> healthy cell. But anything containing water will heat up too, so there 
> must be a balance. Hence the needed research to perfect the new technique.

> As far as lighting up a fluorescent tube: do you remember a lecture on 
> antennas that I gave way long ago at Moto? I lit up fluorescent tubes 
> with a 5W 2m handheld radio to show where the E-field was strongest 
> (its at the antenna tip). Use the tip of the rubber duckey on a 5W+ 
> handheld, keying it on and off as you poke around the tube. It will 
> light up! Its a great experiment -- once to light off the tube, keep 
> the TX keyed and move the tube down the antenna/radio and across your 
> arm to the shoulders. The tube stays lit!  Your arm is part of the 
> "antenna"!!!

> There was an added "feature" to the video-recorded version of that 
> lecture: we didn't know it during the recording, but the hand-held and 
> lit tube produced interference on the wireless microphone feeding the
