Having a hard time parsing that sentence ;) ... but if you're using
DIGOUT1 to control the PR6, you would need to disconnect it from the
inhibit input of the KPA500.
Does the "Keying Line Interrupter" cut both the DIGOUT1 and PTT lines,
or only the latter? If it cuts both, you should be able to solve your
problem by placing it on the KPA500 side of the Y-adapter and running
a separate (RCA) keying line.

Not sure how your problem could be fixed in firmware..........
