The only thing that comes to mind, Mark,
absent a failed component someplace, is
perhaps one of the ribbon cables is
incorrectly installed. Good luck!

I will contact Elecraft tomorrow, but posting in case someone

I just put together a new KPA500 kit. When I select Operate, the RX
through the amplifier is significantly attenuated, many 10s of dBs.
The amp will also amplify even with nothing connected to the PA Key
RCA jack. It seems to amplify OK, 35W in gives 400W out. In Standby
the RX and TX pass through the amp as expected.
It seems to me that it thinks PA Key is enabled all of the time, so
when I switch to operate it is in TX mode immediately. I do not see a
short at the RCA jack.
Any idea of what is going on?
