> If it is a buzz as you describe, then you might be on the wrong track.

Maybe. Maybe not.

Newer chargers, at least all I have seen, are sharp pulses that make 
tics. Most of the fences around here have newer chargers, but there 
are a couple old ones around here that buzz when wires get close to 
posts or have bad splices.

Older fence changers are long periodic raspy buzzes that cycle every 
few seconds. 

Of course small transformers with thermal overload switches, like 
doorbell transformers, can cycle off and can other things 
like electric heating devices.73, Tom W8JI
