Hi, Sergio, Thanks for the note!
I think you are exactly right. I thought about but did not get rid of the path to the diversity antenna. Clearly I should have ;) Let me know if I can help in any way! 73, Roger W3SZ -------------- Original message ---------------------- From: Sergio <[EMAIL PROTECTED]> > Hello Roger, > > nice piece of information from your side (as usual).
