Not sure I understand the problem. If the amp is on STBY then you have to
manually place the switch into OPR before keying. If the STBY/OPR switch is
not working you can use HB9ZS CAT software, to change from SDBY to OP via
software control. You cannot key the amp in STBY position.

Subject: [Amps] Alpha 87A Won't Key
The Alpha 87A I got in the ARRL auction won't key up.
I connected to the RS-232 port satisfactorily, and it showed no faults. I
have the transceiver RF out connected to the RF input of the amp, the RF
output of the amp connected to an antenna (TH-11), and a relay connected to
the keying relay input.
I checked the relay input, and it does short to ground when the transceiver
goes to transmit. But the amp stays on SDBY, and the OPR light doesn't come
on.
Is there something I just don't know to do? I've never used a
microprocessor-controlled amp before, so there may be a trick to it.
I'm on 20 meters, so I assume it isn't a 12-10 meter lock-out thing.
Thanks.
