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
