Default Shortwave diathermy

Just in case anyone is still interested in shortwave related topics in this N.G.,
here is a startling photo and description of what RF can do to human tissue:

http://www.snopes.com/photos/medical/electricfence.asp

When I was a kid, our nearby hospital spit out lots of RFI from diathermy equipment,
and there was a quite predictable schedule for the QRM on several bands, but I don't
remember the frequencies any more safe to say that it was strong on fundamentals
and harmonics over much of 80 through 10 meters.

Think about that photo next time you microwave a wiener.

They used it at one of the local hospitals, and it would put a nice
harmonic on CH 23 on the CB, and was really annoying. I was close enough
to hear it all the way down on channel 11 or so, and the "Boop-boop-
boooop!" was easy to hear all over town..
