[Elecraft] KPA500 down

[efortner]

KPA500 blew both FETS and PA module has been shipped for repairs. I am
trying to use an Ameritron AL-80B amplifier until I get my KPA500 back.  My
paddle goes to an external keyer (Navigator) which is plugged into PTT on my
K3s and the key out goes to the PTT input on the Ameritron amp. The paddle
works fine with the K3s but the Xmit tune button will not key the amp nor
the macro button on CW. I cannot find anything about config to make it work.
Any suggestions.
