Perhaps it fades off higher in the band (in the phone portion) because your
antenna is more responsive down in the CW segment?
Do you know what direction it's coming from? Try peaking it with your beam.
It may be a sharper peak on higher band - like 10 meters. I'd also try
using your 6 meter and 2 meter beams to do the same in that direction for
possibly even sharper peak. (set to receive on AM)
Then take a handheld VHF / UHF radio (on AM) and walk out in that
direction until you find the pole where it is strongest. That may provide
some further clues as to exactly which pole is the source. After all . . .
there is some specific source out there causing the problem.
Knowing which pole is the source, will help your power company crew fix it
faster.
Please keep us posted. That way, we all benefit.
