Any guesses as to the origin of the mystery
noise bugging me this morning would be apprec.

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.

S9+ stations seem to override the click.
S7 stations don't override, the click
comes right through and clobbers reception.

Station is "backyard remote", battery powered,
asymmetrical wire dipole.

I found some recordings of electric blanket
noise via k0bg's site. It sounds very much
like those recordings. Both of the elec blankets
in my home are off and unplugged. Neighbor elec
blankets? They would be probably 100' away from
the closest point to my antenna.

Noise just started this morning. No new elec
or mechanical devices running at my home.
Turned off the A/C, fans, elec fence, light
dimmers, pool filter etc. Three computers
run inside the house, as they have for
years.


Anyone have a guess at this 1 Hz click noise?
TIA -

Hi Lumpy,
I had something very similar a couple of years ago. Noise was burst
about a second apart but continuous unlike yours. I went throufg
everything in the house that could cause it. This went on for a couple
of months until I was riding down a road about a mile from the house
and heard it on my cars AM radio. It was coming from the ranch I was
riding by. I am pretty sure it was from an electric fence charger.
About the time I figured out what was causing the interference they
moved the horses to another pasture an turned off the fence. I
shouldnt have any more problems, the farm was sold and they are
buiilding houses there.
