KRC2 not working after PA upgrade

[Dave Glenn]

I recently had the 100 Watt amp added to my K3.

I went to set it up with and use with my transverters and KRC2 menu item
shows -

Cabling looks good going from 15 pin on the K3 to the 9 on the KRC2.

 

If I power cycle the KRC2 while the K3 is on it shows Turn On PA and is
locked up.

 

Is there some setting I have forgotten?  

Tnx, Dave N6TEB

Dave,

AFAIK, the addition of the KPA3 should not have any effect on the
operation of the KRC2.

Check the jumpers in the KRC2 against the AUXBUS configuration for the
K3 on page 23 of the KRC2 manual.
The two indications of K3 menu for the KRC2 show "-" and the "Turn On
PA" message are making me think that there is some kind of conflict on
the AUXBUS signal internal to the K3 or KRC2.

Pin 9? The KRC2 Auxbus connection is on pin 6. Use pin 5 for the ground connection. If you used pin 1 for ground that should work also.

The 100 watt amplifier should have no affect on KRC2 operation, recheck your internal cabling to make sure everything is OK, and recheck the Aux IO cabling.
It should be:
K3 Aux IO: Pin 2 — KRC2 pin 6
K3 Aux IO: Pin 5 or 12  — KRC2 pin 5

Make sure the W jumpers are set properly. If you are connecting the K3 to the KRC2’s XCVR port, be sure that W16 is installed. In general you can remove Ws 17-23.
That is all that is needed.

Power cycling the KRC2 should have no effect on the K3. If you have changed W1-8, power cycling will have affect on the KRC2, however.

Give me details of your setup and I’ll work with you to get things going.
