[RFI] Power Line Radiated Interference Limits

[Charles Plunk]

Looking back in the archives of this group should yield what you seek. 
Pay particular note of Ed Hare's response on the subject for regulatory 
standards. Part 15 mentions "harmful". I guess what is harmful to a 
moonbounce operator maybe different from what is harmful to a 80m op. 
For me, as of the last 8+ months or so I am free of 120hz rfi except 
distance sources and they are very intermittent so I can easily live 
with that (sometimes using NB but not very often) and do not consider it 
harmful for me. But the 20db over S9 I use to have definitely was.

Here is a sample letter at the ARRL website which specifies the Part 15 
sections although it does not go into detail but I'm sure you could 
google that; https://www.arrl.org/fcc-power-utility-letter

Let us know how it goes.
