Hi guys .Can anyone suggest ways to reduce ctcss dropout when someone
is talking loud on a repeater .The repeater radios are maxon pm150
(sm4450sc) and I have tuned them using 600hz of ctcss and a 1khz tone
at 3khz modulation to make sure it doesn't
I have to wonder how you can know this is a signal passing out of the
passband as opposed to talkdown (what the OP was asking about). Both
would sound virtually identical.
While I agree deviation should be checked, I wouldn't go so far as to
rule out either cause based on the description.

Ian,
I suspect that the problem is talk off caused by overdeviation of the mike
audio. When the CTCSS tone is mixed with the mike audio prior to the
deviation limiter stage, an excessive voice signal will be hard limited
along with the CTCSS tone, causing a distorted signal. This problem occurs
