We had the opposite problem here in NH. The aluminum wires are held to the
insulators with aluminum wire wraps. The wraps would arc when dry conditions
existed.
Morning dew or rain would make it quiet. Dry days in winter would be the worst,
the noise would wipe out AM,HF, and weak FM band signals. I swept the area with
an
aircraft HT (VHF-AM) and a 4 element beam. Narrowed it down to one pole by
tugging on the guy wire to pole and setting the wires into motion to confirm.
Power Co
came out with a sniffer (VHF/UHF?) and confirmed the location. All three phases
were tightened and the QRM went away!
