I remember a while back I was asking the same question about using my K2 and KX3 with my KPA500/KAT500 combo, and Eric responded that the KPAK3AUX Optional KPA500 to K3 AUX Cable Set cable should be left disconnected when using another rig besides the K3. I was debating on using a DB-15 data switch so I wouldn't have to keep plugging/unplugging the cable.

I wasn't expecting any kind of comms between the K3 and the KPA500 that affects the STBY/OPER switching. It does seem that a power on/off cycle for the KPA500 is required to enable that switch. Is this designed to work this way or is this a flaw in the design or maybe a missing mini-feature of configuring two different transceivers with the KPA500. I admit to not scouring all of the documentation yet on the expected functionality of the STBY/OPER switch. 73, phil, K7PEH On Apr 22, 2014, at 4:14 PM, Don Wilhelm <[email protected]> wrote: > Phil, > > Let me get this straight - the KPA500 is communicating with the K3, then you switch to the KX3 and the KPA500 does not talk with the KX3. > > If that is what is happening, I would expect that to be the case. The communications with the K3 is not synchronized with the attempted communications with the KX3, so a reset (power cycle) of the KPA500 may be required. > > 73, > Don W3FPR > > On 4/22/2014 7:02 PM, Phil Hystad wrote: >> Some follow-up questions: >> >> OK, I have the KX3 and K3 configured with the KPA500 and KAT500.
