[TowerTalk] RFI Identification

[n8de at thepoint.net]

Tony,
Sounds like an electric fence with a leakage or discharge path.
Any farms in the vicinity?  How about someone with an electric fence  
to control predators?
We have one here and it make the exact sound you describe when one of  
the insulators on a fence post leaks.
Good hunting.
