Same problem with the CAT200 controllers as well. The
recommended procedure for adjusting the DTMF input
level seems to call for a specific amount of audio on
a test point. If the radio you use to adjust the CAT
is on the low side (deviation), then it will be a bit
over-sensitive and will mute occasionally on some
voices. Lowering the setting just a bit will fix
things for most users; the rest will need to adjust
their own radio deviation levels.
The CAT manuals have the adjustment procedure and test
points well documented.
