I've experienced this several times Rick. Once, it was because I had
dismantled my control setup and when I reassembled it, I forgot to use
the null modem cable between the K3 and RRC. The other times [three
maybe], it's been a bad RS-232 DE-9 connection at the RRC. I think it
is only one pin ... apparently all DE-9 jumpers are not created equal.
I use a mechanical A/B switch too.

I seem to be suffering a recurrence of a very old problem (years ago) for
which I don't recall the solution:
I have a real K3 at the control site, controlling a K3 at the remote site
via RRC-1258 MkII boxes. I have a mechanical D-SUB 9 pin switch to route
the control site K3 serial port to either a local computer or the RRC. When
routed to the RRC and operating normally, when I turn on the K3 it begins
to show its power-on banner in the VFO B area, then mid-way through that
scroll detects that it's in TERM mode with an RRC connected, powers up the
remote K3, and all is well. However, that doesn't seem to be working now.
The control K3 comes up and fails to detect the RRC. The power-on banner
for the control K3 completes its scroll and the radio operates locally. I
think it is slipping out of TERM mode. I can force it back into TERM mode
with a long hold of the CONFIG button, but then it never turns on the
remote radio. If I turn off the control K3 and then back on, it apparently
has forgotten it was in TERM mode.
Any advice?
Thanks,
