Hi Ed,

I would look first for issues with coax connectors, like junk 
connectors, connectors that are not wrench-tight, poorly soldered 
shields. Also, I would look carefully at bonding in your station and in 
your home. Study http://k9yc.com/GroundingAndAudio.pdf  or N0AX's recent 
ARRL book on the topic of grounding and bonding, which incorporates the 
concepts in the pdf.
