Doug, this might be a street light cycling at night. It's a little fast of
a
cycle, but they only come on at night.
Suggest you drive your neighborhood at night with a BC radio and you
should
be able to find this if it is a light,
while observing it go off and on.
The noise is very strong as the light comes on and quiet when it goes off.
Good Luck,
Lee K7TJR

Symptoms:
Primarily on 160. Although it is also present on 40 and 80. It is much
stronger on 160
Only on at night...after dark.
Cycles On and Off at set intervals. 20 seconds On and 30 seconds Off.
Produces S4-5 spikes every 2.5 to 3 Kc
A neighbor less than 1/4 mile away recently installed an electric fence. I
do see regular spikes, very short in duration. Not really that much of an
issue.
I have verified that it does not come from within my house.
I have a picture of the interference on my SM-5000 station monitor if
anyone
thinks that would help.
Any assistance would be greatly appreciated. It has really put a damper on
my 160 operation.
Doug - K1ZO
