Cortland,
Thank you for reinforcing my point about the FCC's deplorable lack of guts
and common sense with emissions. The situation for TV receivers, plus the
general lack of radiated emissions requirements testing below 26 MHz for
Part 15 devices, sure does raise havoc with HF communications.
One has to wonder what the story would be if the US was to ever have a
licensed, active ham as an FCC Commissioner (not likely anytime soon - if
ever!) who gets clobbered by garbage emissions from Part 15 devices in
his/her home or from neighbors. Oh well, worth a few chuckles.
