<DIV>GM300 Pin 11 - RTCM Pin 3 - Rx Audio JU 551 inside the GM300, in
position A gives FLAT (not De-emphasised) audio out pin 11.We want to use the
RTCM's internal Squelch.</DIV>
<DIV> </DIV>
<DIV>So pin 11 on the GM300 already has the flat audio we seek. But Jumper 551
to the A position is the best audio? OK. Buy why the RTCM’s squelch? I know that
we’ve had problems with squelch tails...</DIV>

<DIV>I’ll confess that I am new to this part. It was dumped on me without
warning and that’s OK. Time to learn a few things. I have a GM300 that is
going to be a remote base and a cable purchased from eBay that is prewired for
the GM300 side. I understand (I think) that TX goes RX, RX goes to TX, GRND to
GRND – but now for PTT, COR and CTCSS. I wonder if some could push me over a
cliff – I mean in the right direction. I have no documentation on the
RTCM.</DIV>
