Ok so I just found a problem when digging around in the radio.  Looks
like the screw in the top of the KAT3 board wasn't replaced.  Putting
that screw back in makes the radio show the signal at S1.

Good eyes! That's a real easy one to forget since it's nearly hidden under
the lip on the rear panel. 

You're not the first to have strange problems caused by a poor ground at the
KAT3 because that screw is missing. 

Because of the work I do I've had my K3 apart - literally from a
fully-assembled rig to a kit of parts again and everything in between - more
times that I can possibly count. 

I have some small containers in which I put the hardware when disassembling.
If I'm disassembling parts that include critical but close screw sizes -
such as the front panel bezels - I use more than one container. I always
start with *empty* containers. 

When the radio is back together, I check to be sure the containers are
empty. If not, I go hunting for where I left out a screw or a washer.
