You might want to help out the local pwr company by giving them the
"pole number". Where I live this is a vertical strip with 5 digits on it.
The folk I have talked to when reporting a light out or other problem
have greatly appreciated this info.

The street lights we have in our city (Bloomington Mn.) have a little device on top that senses when it's getting dark and to turn on the individual street lights. When that thing goes bad or if the ballast inside the light fixture goes south, these lights can produce ungodly amount of on and off noise. I have found these things several blocks away from my QTH with interfering noise. Sometimes when they are in failure mode they will be on steady during the day. So if you have this type of street light drive around for several blocks away from your QTH, night is best as these things will be on bright for a half minute or so then suddenly shut off, wait a few more seconds and you will see them start to come on slowly and that is the time they generate their noise, awful noise and on the low bands, 80 meters which I use. Fortunately for me the local power company has responsibility for maintaining these lights and they have been responsive to my calls, depending on other
wo
rkload priority.
I'm not saying this is your noise source rather just sharing my experience with
on off type noise, as another poster mentioned it too.
73 and I hope you can find it.

Upon further investigation I have discovered that the interference is also
present during the daytime although it is much lower in amplitude. It still
maintains the same On/Off cycle.

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.
