Hi all...got a lot of direct and via list replies. Thanks. Here's the
additional information:
First thing I checked was the bandswitch -- I was on 160. Got burned by
that. once I did not try other bands.
I do hear the relay actuating when I am in OPER mode and I key up.
Using an MFJ989B to show forward and reflected power. When in STBY and I
key up I get forward power. When in OPER the relay clicks when I key up but
nothing forward on the MFJ989B.
I am not sure that there is continuity with the relay activated -- Easy
enough to check.
