Heck, no one wants hf (at least around here - and the FCC has no authority
in Africa). It is VHF and above where the money is. Who wants a cell phone
when someone can come on yelling "audiooooooo ..." from 5 states away?
Nope, hf bands are probably *reasonably* safe. My bet is that 220 and 440
are the next to get hit, but I hope I'm wrong.

Safe from direct use, but not from pollution like BPL...
