Topband: Electric Fence QSB

[Bruce]

Interesting observation:
Listened on  160 meters at mid-day I noticed S-8 electric fence pulses.
I checked the front to back on my Beverages to determine the origination
direction and was southwest. Then noticed the signal had slow QSB.
Electric fences can be / (are) spark transmitters. Propagation is
possible.
My questions are:

1. Anyone experienced this before?

2. If yes, did you find the source?

3. If  yes, how far away way was the source?

4. Anyone else in the Northeast USA hearing this noise signal?

Thanks, Bruce
