Hi Don,
Correct me if I am wrong.
The back panel diagram of the K3 shows two BNC's labed RX antenna. I
thought the thread originator was referring to this input path for a RX
antenna. It's what I use for RX antenna input.
I see "spark gaps" on the inputs on those pages you quote. I don't see
a carrier operated relay for the above BNC's. If it is there. I don't
see it on the schematics. The relay that is there is to complete the
rx/tx circuit when the BNC's are not in use. At least that's what I can
glean from the circuit.
The aux antenna BNC didn't come till later when the subrx and diversity
reception became a reality. It does have a real relay that goes click,
click with too much RF. It also has a spark gap protector.

All the antenna configuration diagrams in the K3 manual show a COR on
the RX ant input.
See pages 41 through 44.

There is no COR on the RX antenna input (it's not needed, I think.)
