You could try electrically cleaning the relays, shown here, near
the bottom of the page:

I think my AL-1500 has just started exhibiting the same problem.
I'll give this procedure a whirl next week.

Subject: [Amps] Ameritron AL-1500 inquiry
I have a later version of this amp that uses two Schrack sealed
T/R relays
(1 - RTD14012F SPDT 16A and 1 - RTE24012F DPDT 8A both 12VDC) for
antenna switching mounted on a small board.
The manual shows the earlier version with the open frame 3PDT
relay.
I use this amp occasionally and has had the problem of
intermittent receive.
The relays have already been replaced once to solve the problem
but it
has returned.
Does anyone have a mod or suggestion on how to solve this issue?
I have considered the W7RY QSK mod but I don't use QSK.
Thanks in advance.
