[Elecraft] KPA100 has 0.1 w indicated, SWR 1.0 during tune test

Good point. I would think so.

Wouldn't that (failure in coax confection to K2) prevent the receive from
working? I have good reception, but no TX.

Did you dislodge the connector on the coax between the KPA100 and the K2
main board? If in place, is it oriented correctly? While keyed, it can be
reversed by a clever person, Hi! 

You can see that connector by simply removing the K2 side panel. Usually
take if off when replacing the KPA100 just so I can see the cables and
connectors clearly. It's easier to plug the power and RF cables in AFTER
putting the KPA100 on than trying to do it holding the KPA100 up enough to
see in from the top.

I am attempting the C1 adjustment to get correct SWR. Unfortunately, with a
dummy load on the SO239 port and the power knob set to 5w, pressing TUNE
just gives a beep followed by 0.1 1.0-1. Adjusting C1 has no effect at all.
The receive audio does cut out while tune mode is on, then reappears when
off.

I get the same behavior whether 8r is set to norm or hold.

I'm guessing there a break in the transmit RF path somewhere.  *sigh*
