[Elecraft] [KPA500] latest upgrade

[GDanner]

Thanks Jack

Quick test confirmed that the display on the K3 indicated the KPA500 was 
"ON" but the power remained at 100 watts.
Don't remember if K3 displayed "OPERATE" when it turned on before the 
installation of my KAT500 & FW upgrades.

BTW - I also set Power-On = STBY

OK Folks, I will confirm the bug. We are working on it now and will have a 
solution ASAP.
My tests show that communications is normal after this point, meaning that 
the KPA properly communicates the OPER mode to the K3.
The work-around is to set the POWER-ON mode to STBY.

Our apologies for this glitch. We will have it resolved shortly.
