This as a VERY serious problem for all radio users -  there seems to no 
longer be any interest in control of incidental RF radiators.  For 
example, when I got an FCC field engineer  to come out and test some 
noisy LED traffic signal systems, he said (paraphrasing), "Yes, I can 
see none of these are meeting Part 15 requirements, but hey, people can 
just listen to the stronger signals that get over the noise."  And 
shrugged and went back to the office.

I did a study of the noise problems for FM broadcast reception due to 
locally-generated noise.  You guys might find it interesting as it 
really applies to the whole spectrum (I just needed to focus on our 
industry in particular). I've posted a copy of the resulting paper on 
my website at

Since it's not something likely to end up in use on the ham bands I 
wouldn't
waste my time worrying about it.  Let the broadcast people take care of 
the
problem, if there is one.  The commercial FM and AM bands have 
degenerated
to little more than a vast wasteland anyway.

I'm far more concerned about all the consumer crap on the market to-day 
that
dumps buzzies and hash all over the HF spectrum, with apparent impunity 
.
