The antenna relay is used when the amp is in the bypass mode, If you notice
the relay clicks when you change the "in/out" switch on the front
panel......The rx path (and exciter path) is through the normally closed
contacts of the relay.....
Clean the relay....
good luck and 73!

Subject: [AMPS] AL-1500 problem

>Hi,

>I have an AL-1500, no longer under warranty, with the built in QSK
>board. Over the weekend it developed a problem: received signals
>are markedly attenuated when the amplifier is off or in the standby
>position. If the amp is up and running everything works fine, but
>as soon as I flip the switch from operate to standby, or shut the
>amp off, the receiver is nearly dead. This affects all bands. The
>swr seen by the transceiver goes sky high once the amp is put in
>standby or shut off, also, although it is fine when the amp is running.

>Any suggestions from others who've experienced this?

>Thanks & 73, Arliss
