I've mentioned my rfi problems here in the past, but I just noticed
something I hadn't before. If I sit on a frequency where the rfi is
present
it will abruptly cease in about a minute, and move up or down in frequency
roughly 30 kHz to occupy another point previously unaffected, and on and
on.
Is what I've described indicative of a particular source of rfi?

Possibly something like central air, heat exchager, etc. Possibly something
that uses a thermostat or timer.
