Start with the basics:
1. Clean all of the contact pins and female contacts with a good contact
cleaner like Deox-It. When re-installing each of the boards/cards, check
check to make sure that all of the male pins are straight and that none of
the female contacts have "spread" - tighten up by squeezing gently with
needle-nose pliers where necessary.
2. Clean (or replace) the IDC pot if you haven't already.
If speaker audio is normal and doesn't vary in level, and/or if PL injection
doesn't change when the audio level changes, chances are it's somewhere in
the repeat audio path. But if speaker audio level changes too, then
clean/replace the audio level pot on the audio/squelch board as well.
Those are my first-pass suggestions. If you want to provide more detail on
the problem, including what cards you are using and how you have Tx and Rx
wired from the controller to the station, I can probably offer some other
suggestions.
