[ICOM] AT-500 "Wait" LED constantly On

[Tom]

Brian,
What radio are you using with the AT-500? Did the
combination ever work or did you just acquire this
equipment?
I am thinking that you would be smart not to discount
the possibility that the AT-500 is actually OK and
that the problem is with the cable between the radio
and the tuner. Does the tuner make the sounds of going
through the tuning process?
I would get the diagram for the cable (can't help you
with that- sorry) and check its continuity from pin to
pin.
best of luck
Tom, W3TMC
