Hi All,

I have been at this for 5 days using AI as a guide to get it configured but i think google AI is not giving me correct info. i am trying to use ASL3 as a GMRS repeater controller minus ASL linking features since GMRS disallows linking. i am using Tait TM8105 headless UHF mobiles x2 has 15 pin accy port, DMK URIxB P/N:9107 interface, RPi3, and ASL3.

in short help!

thanks

You'd need to describe what actual problem you're running into. As long as the TM8105 puts a COS/CTCSS and PTT line on the accessory port, there shouldn't be anything novel about the situation. Just make the node a private number between 1000-1999 and follow standard setup otherwise.

Looking at that I'm not seeing anything that indicates COS/CTCSS by default, but this makes it seem like the pin out is programmable.
