Thanks to suggestions from Dick Dievendorff, the problem seems to be an interaction between the XKPA100, and the software I was running, DXLab Suite, in particular Commander. I had continuous interrogation turned on. If the software was started before the station equipment, in confused the power-up of the KXPA100 which occasioned the other bad behavior. By turning the continuous interrogation off, the order of power up and software does not affect things.

Folks,

up til today my combination in the subject line has worked flawlessly. Today a couple of problems surfaced. (1) the power switch on the PX3 is intermittent for ON, always works OFF. In other words, it does not always power ON when asked to, but always powers OFF when requested to. Not a big deal, but would be nice to fix...

(2) the KXPA100 would not come on; in trying to track it down, I observe that the PA mode in the KX3 was OFF; setting it to ON, the KXPA100 turns on, and the Sys Fault LED flashes, then it turns off the KX3 PA mode and itself OFF. Big deal, and would love to fix it.

I have rechecked all the cabling and removed and reinserted it i to no avail.

Thoughts or suggestions?

Thanks & 73 de Dave, W5SV
