Since the GM300's are typically "low" for PTT, I suspect an issue where a pull-up resistor would help. I run an M120 for the link and its worked 100% for me, using the default accessory config (PTT low). Since the timeout timer takes over, this also would point to an issue with the external PTT.

Hello all! I am a new user of the app_rpt. I have been having an issue where the repeater will stay keyed until it times out. This usually happens after a transmission, it will stay keyed up until the timeout in the gm300 shuts it down and yet others its like a reeeeealy long squelch tail (about a minute to 1.5) during this time it will pass no audio. I wanted to ask if this has happened to anyone else? what did you do to fix it?

Thanks, Kyle
