GM John: I'm not seeing that problem here with KPA500 s/n 234 and a recent K3/10 (s/n 54xx). I'm using FW 4.39 in the K3 and FW 1.11 in the KPA500. (Gary sent me this most recent FW for the Amp on Fri).
I changed the PWR ON config in the KPA500 to "STBY" and the only thing it affects is the power setting when turning the Amp On. Changing bands from either the K3 or the Amp doesn't change OPER to STBY or STBY to OPER. I've set the STBY power level to be 5 W and the OPER power level to be 125W (approx 8 W from the K3) on all bands (all in CW mode). Then regardless of which unit is used to change bands and whether the Amp is in OPER or STBY the power levels are as just indicated. It works as expected. Hope that helps. 73, Doug VE3MV ----- Original Message ----- From: "John E.
