Some other thoughts and tips.
(1) Is the breaker circuited only to your shack, or are there other
rooms and locations that is on the circuit?
(2) Since electrical noise is rich in harmonics, try using an aircraft
scanner, or if your two meter walkie goes into the aircraft band, use it
with a short antenna -- perhaps a beam to sniff out the noise. The
aircraft band is AM, and is several harmonics up. Since it's harmonics,
the TX power is much weaker and localized.
(3) Maybe the HF rig has gone bad. Try borrowing another HF radio and
see if you get the same results.
