[RFI] RFI Identification Help

[Doug Scribner]

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.
