I tried using the OT2m with a Motorola GP300. The GP300 and the P110 use the Mic output also for the PTT. I proceeded to set the HT jumper just like it says on page 7 of the Tracker 2 manual to enable PTT signaling through the output line, after setting the jumper the PTT was stuck on. Nothing made it set to off except removing the jumper. Does anyone have any idea on what I should do to make it work properly?
