I'm hearing an S9 "click" at just about
once per second, everywhere on 20meters
where there's not a powerful station's
signal. It clicks for maybe 3-5 seconds
then stops for a few seconds. Not always
symmetrical (3 sec noise ~ 10 sec no noise).

Click sounds like what I'd imagine a charging
and regularly discharging capacitor might do.

Freq independant, it's everywhere on the 20m phone segment.

Do you live on the country side? Could it be a farmer's electric
fence? If not that how about the ignition system on a gas central
heating system

We live on a small suburban ranch. We have elec
fences as do some neighbors. Ours is off for testing.
I'm not sure what a furnace is. It's 100 degrees this week
(unseasonably low) in Phoenix..;-)

After sniffing around with the MFJ, and finding
my rain gutters seem to be resonating at about 30Mhz
I moved my dipole a bit so that the coax doesn't
cross the gutters. Now the coax goes from top of
mast to ground, and gets buried under about an
inch of sand on our beach. Previously all of
the coax was suspended above physical ground.

The click seems to be gone.

Perhaps the gutters were receiving neighborhood
clicks and rebroadcasting them into my coax.

Hmmm...30 MHz gutters...Maybe I'll work some
10 meters.
