I have had a number of RFI instances and less than 50% are power line
related. So the question of what if they (the power company) find the
problem is in a house or business is very possible.
Here is what I have found:
1. Door bell buzzers.
2. Bad switches in my power panel.
3. Defective motors in fish tanks.
4. A bad UPS at a software company
1/2 mile away.
5. A defective motor on the AC at the same software company.
6. Defective electric fences.
7. TV sets that generate noise.
8. Touch on lights (160 and 80).
Another problem for underground utilities is bad grounds and lightening
strikes. The problem usually stops between 7 and 10 Mhz.
Power Companies have full work loads already and at best they will have a CB
sniffer.
Private homeowners and businesses do get FCC letters just as do the Public
Utilities. So its probably up to the ham to find the problem and ask for
help. The FCC is usually the second level of help.
