Doe it only come on at night? I've had faulty street lamps in my
neighborhood that have made similar noises. The lamp starts up then goes
out. The restart sequence makes a lot of noise, then the cycle repeats.
Look for intermittent or flickering street lights.

TT'ers,
I have some ugly new noise at the QTH. Starts out low and quickly
builds to S 5-6 (RF gain up, 500 hz filter) for 10-20 seconds, and then
abruptly stops. It seems to cycle about once a minute. The Omni 6+ NB
does a good job on it, but when a strong adjacent signal starts up
(within 10 Khz or so), I hear the guy's CW as raspy noise in my
passband, and its strong enough to wipe out weak sigs. The occurs when
the noise is strong. When the noise is absent, I don't hear the garf
from strong adjacent sigs.
Any idea on what this type of noise is? If its from a power line or
transformer, would it cycle like that?(I'm going fox hunting with a
portable AM radio tonight).
What causes me to hear the raspy CW when the noise is there, but not
when it isn't, and is there anything I can do about that?
73,
