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.
I seriously doubt it's "lack of guts", although common sense is another
issue.
If you look at their recent history you should easily identify a trend.
Look at what they did with LightSquared, violating their own rules in
the process. Look at the revolving door from the agency to high places
in industry. Not saying they have a conflict of interest, but when they
have to violate their own rules to please the present administration it
might lead to an atmosphere of trying to please...well, use your
imagination.
OTOH shortages of personnel and funds have always been a hallmark of the FCC
Whether it be over regulation or lack of enforcement in specific areas
it is endemic across many agencies, not that I'd accuse any of them of
favoritism or wrong doing. Far from it. I'm sure they "Want" to do as
their charter says if they were allowed to do so.

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.

TV receivers are not tested for radiated emissions below 30 MHz.
From FCC MP-3:
http://transition.fcc.gov/Bureaus/Engineering_Technology/Documents/measureme
nt/mp3/mp3-1985.pdf
8.2 Electromagnetic field: 30 MHz to 1 GHz
Any equipment to which it is applicable shall be measured for
radiated radio emissions from all units, cables, power lines and
interconnecting wiring.
IMVH (yeah, right)O we could ask the FCC to revisit this standard, now
that TV receivers have screens large enough to be significant radiators
all on their own.

Mike,
They most likely DO pass "testing standards". That shows what a piss
poor
job the FCC has done with regards to emissions on so many devices.
Remember, the "warning" label on Part 15 and similar devices says that
the
device must not cause interference and it must accept interference.
Right.
Per the FCC, you can go tell your neighbor to not use the TV during
whatever hours you operate. Lotsa luck.
