[RFI] Power Line Radiated Interference Limits

[Charles Plunk]

Oh, I would try to exhaust all other tactful ways of getting it fixed 
before pointing out reg's to them. If they worked with you 7-8 years ago 
then likely they will now. But I understand if you are trying to get 
prepared "just in case". Knowledge is power they say.

I would be prepared to explain to them why you believe its power line 
rfi and not another source. Such as a way of identifying the 120hz. 
There are ways to do this. I usually record the noise and expand it out 
on a audio manipulation program such as Audacity and count the 120hz 
spikes. Others do it differently.

And of course, you have shut down your main breaker to your house while 
powering a receiver on battery to try that first?

After doing those things, hope your power co is large enough to have RFI 
location gear. Mine is small thus I find the poles myself with my 
accumulation of various gear, some homemade :-).
