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:

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.

Circa 1960s - Used to get a beautiful scrolling pattern
on one of the Lower VHF TV Channels when the local
Hospital {three blocks away} was running one piece of
their Medical Equipment.

First checked the TV and Antenna and Grounds.
Next checked the TV's AC Outlet and found that
it was reversed : Rewired it correctly and no more
beautiful scrolling pattern.

That is interesting, was the TV on of those hot chassis types by
chance or standard linear power xtranformer power supply?
