Last night I had to move some cables around with in the rats nest behind
my K3. Unrelated cables, so I thought, they were for the VGA output for
the P3 to add a data switch before the external

Sam, I run the KX3 line: KX3 to a KXPA100 to an Ameritron ALS-600 to the
KAT500. Little lines all over the place, and hi-power LMR-type coax out of the
linear. Cardinal rule, I am told, is to avoid those high power RF coax cables
as much as possible in proximity. For instance, never drape a

It sounds like the Auxbus is no longer connected from the KPA to the KAT/ K3.
Make sure the 15 pin connector is solidly connected on both sides at both the
KPA and the KAT. Also, make sure no pins in that cable are bent.

That was my thought Jack. I just re re checked, no bent pins, and both

The KPA is still set for RADIO= K3, right? Shortly after power up, the KPA will
send its on state to the K3 using the Auxbus, but only if it is told the radio
is a K3. The symptom is that this is not being received by the K3. The logical
conclusion is that something is blocking it. Nothing
The only cables changed during my clean up were:
I removed the VGA cable from the P3 (the one that went to the external
monitor)
I then took that end that had gone into the rear of the P3, and inserted
it into a 4 way switchbox.
I then added a new VGA cable from the switchbox to the rear of
Yes RADIO is still set for K3.
Last night I had never even touched the cable that went between the
KPA500 and the KAT500. Unless Murphy got in here while I was sleeping
and broke a wire inside the cable that hadn't been touched...
yea I know stranger things than that have happened b4, hi hi.
Connection to Pin 2 somewhere in the K3 to KAT500 cable is broken!
thanks to *all* who pointed the way to troubleshooting the problem!!!
