[Elecraft] KX3: nearby noise post-mortem

[Don Wilhelm]

Nick,

The wire should run outside.  It can and should be buried.  It does not 
have to be down very far, but deep enough it will not be damaged by the 
lawn mower or shovels if you should dig in that area.
A perimeter wire around the house would not be a bad idea either, it can 
divert a lightning surge such that it does not punch a hole in the 
foundation.  If you are also using the wire for that kind of protection, 
it should have a ground stake each place where the wire makes a turn - 
lightning likes to move in a straight path.

73,
Don W3FPR
