OK. I just checked the manufacturer's site. The specified voltages are:

11.5 KV when the entire fence is "open circuit" and 2650 Volts at 500 ohms.

even less at another.

300 Volts, if that is an accurate measurement,  indicates an impedance of 
less than 60 ohms. (2650/500=300/X)

There is DEFINITELY some sort of short-circuit somewhere in that fence 

I REALLY think that even you could "feel" a 2600 volt pulse!!!! I know I sure 

Also, the unit is specified for use in small to medium pastures, whatever that 

There is most certainly something wrong with the installation. My suggestion 
to disconnect, completely, the bottom strand of the system, then to re-check 
its performance with only the top, completely clear (supposedly) strand would 
at least make the issue more clear.

Someone else here with far more experience than I with farms and electric 
fences also said that in his opinion there was definitely a problem with the 

Have you yet compiled the info we have tried to share with you and 
presented it to the other fellow?

Have you taken this man to the point in his fence system where YOU felt 
almost nothing and had him "test" it himself?

If you cannot convince him of 1) your competence in such matters, and 2) 
that there IS a problem with his installation, and 3) that it is MOST LIKELY 
his installation that is causing severe interference to your federally licensed 
radio station, then maybe you had better consider calling in some "bigger 
guns" if such exist in your area.

To my way of thinking, this has gone far enough.
