I don’t recall what the serial port decode means but I have seen this happen a 
few times either when the relay line physically gets disconnected or your 
transceiver relay line gets shut off inadvertently (happened to me with my 
IC-7800).

All of a sudden, my Alpha 87A has stopped amplifying. It had sat for about a 
month with no use. Everything seems normal: the correct lights come on, the amp 
seems to switch into operate mode, but the output power is equal to the input 
power. When I transmit, the serial port puts out a series of RM50E00, RM50D00, 
ending with RM00000. I don't know what else to look at.

 

Any suggestions before I start taking it apart?

 

Thanks.

 

73,

Frank
