KPA1500 RX signal loss

[N7US]

My KPA1500 seems to disconnect the antenna when switching the amplifier from standby to operate.  It transmits OK but the receive signal path seems to be open.

Check if the key line is stuck on. Is the TX LED on when in receive?

Yes, the TX LED was on, that was it!  Now I gotta figure out why.  Thanks, Mark.

Fixed, power cycled my microKEYER III, which keys the KPA1500, and all is good.
