Hello to the collective brain:
I am now, for the first time in a nearly forty-year career, dealing with FM
RFI complaints from a new FM station facility (15kW ERP/ 400' HAAT).
These complaints include demodulated audio in PC speakers, garage door
openers that no longer work, as well as the customary "I can no longer pick
up a station I used to hear that's 95 miles away," etc. My experiences in
this area have all been with AM stations as the facilities over the years
I've had with FM have been operating from towers in wide-open farmland or in
the swamps of Florida (I always seemed to be the C.E. for an AM with its
site located in densely-populated residential areas). AM RFI in some
respects, is easier to resolve inasmuch as good grounding can resolve most
I'd like to hear of the experiences/solutions from all of you on this board.
I believe sharing these would be of benefit to all of us.
