[Elecraft] Using K3's Pre-amp

[Don Wilhelm]

Adam,

While power lines can be a noise source - cracked insulators, dusty 
insulators, arcing transformers, etc. - those power lines can pick up 
noise generated by some other source and carry it long distances.

A good way to track down noise sources is with a portable AM radio.  
Some have loop antennas that are very responsive to orientation, so 
looking for the null in the noise pattern can often help lead you to the 
source.
