Roger,
As others have said on this list before, you can spend a lot of time
speculating as to the cause of an RFI source. What matters is to go find
the source. If you think it is about a mile away, get a portable receiver
(or a rig that runs on 12 VDC) and go for a drive, including suitable
antennas for the band(s) of interest. You certainly need to figure out if
it is from a power line source or a house/business. So, as the realtors
say, location is everything.
