[Elecraft] amp tune

[jeff kb2m]

Thanks for all the replies to my 'problem'. Dave was right I had the amp key
rca cable plugged into the PTT jack. All is well in kb2mland once again...

Jeff, sounds like you are connecting your linear keying line to "PTT IN"
and not "KEY OUT" as you think you are... Check the connection.

I'm trying to setup my K3 to tune my tube amp. I have TUN PWR set to 25
watts. when I long press the tune button the K3 goes into transmit at the
selected 25 watts, in CW mode, but the amp doesn't key. If I press the PTT
on the mic the amp goes into tx. I must have a menu set wrong? The only
connection to the amp (other then the coax!) is the RCA connector key out on
the K3. on Tuner is in bypass, ext ALC is OFF. Any ideas??
