Hi Chuck,
Thanks for the detailed description of your problem and how you were able to
find it. I have power line noise prevalent when dry and windy. You can watch
the noise floor jump up and down. When it rains or not windy it usually is not
present. When present the noise floor on 40 and 15 meters is 20 to 25 dB
higher. Using the Flex Wide Noise Blanker I can get the noise to drop almost to
normal, but as the arcing comes and goes rapidly with windy day the WNB keeps
trying to reobtain lock.
I have narrowed it down to what I think is a single pole on right front corner
of my property. I will try the binocular trick at night. It is supposed to be
windy tomorrow with drying conditions.
The good thing is I know the person in charge of the group that would respond
to RFI noise complaints at the local utility company. He has been very
cooperative in the past.
