Oh, I forgot to mention that might be applicable for someone who knows more
about adjusting these things. You mentioned a/c gate misalignment and that jogged my
memory on this thing. The "reply" light has always been a bit flaky on this box.
When it's receiving a signal, it's always done a quick, multiple flash... pretty much
at every interrogation. It doesn't just pulse once every few seconds like it
should... always blink-blink-blink-pause-blink-blink-blink-blink-pause....

Certainly sounds like it could be some digital timing gone awry and it's just
"marginally worked" before.

What say you (all)?
