Solution 4:

Remind the neighbor that interference from an electric fence is not
permitted.  Even though such interference falls under the umbrella of
"incidental radiation", it still must not interfere with the operation
of a licensed radio station.  There are some fairly recent (within the
past 5 years or so) cases where the FCC got involved in this type of
problem, and some substantial fines were assessed.   A search of QST
archives should turn up some of Riley's correspondence on these issues.


Attempting to work out the issues with the neighbor may be useful, as
electric fences are not supposed to radiate, and there may be repair
actions that can substantially reduce or eliminate the problem.  
However, I  advise  anyone with this sort of problem that the only
assistance you should provide is in identification of the noise source,
and monitoring to verify that repairs have been effective.


Do not under any circumstances attempt to repair the equipment
yourself!  Not only can such equipment generate hazardous voltages,  if
you make a repair, successful or not,  you could find yourself liable
for damages should anyone subsequently be injured by this same system.  
You could also find yourself sued for the cost of later repair or
replacement under the assumption that since you are not a professional
service person for the device, whatever you did "caused" any subsequent
problems.
