Jay, Stuart, Clark, Mike, Jim (and others I have probably forgotten to list),
Thanks for the help! The problem is linked to an antenna switch -- an MFJ
1702B. I use a delta loop on 40 and a dipole on 30; the switch goes back and
forth between these two antennas. Once I changed the coax run so that it
went directly to the back of the Argosy, the BCI was gone! (I should have
known better - this switch drives my synchrodyne/direct conversion rig crazy
with noise when I change antennas! Obviously, there is a contact issue
here.)
I am very grateful for the help.
Thanks!
