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.
