<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>
