The LAST thing we would want to do is involve the FCC in this. Far 
better to police this ourselves.

As to checking your own rig -- someone who knows what they are doing can 
use a P3 connected to the IF of a radio with a bulletproof front end to 
take "before and after the fix" screen shots of your signal and compare 
them. You need to be loud enough at the station doing the measurement 
that you're at least 50 dB above band noise. I made the P3 measurements 
on the 7600 on 10M when the band was dead, with a station 10 miles from 
me. http://k9yc.com/K6XXAmpTalk.pdf  There are several other P3 traces 
done during a contest with many signals present, looking primarily at 
two very strong ones.
