Hello!
I just recently got my Technician's license (November 29th, 2025), and along with it, I received a Retevis RT3S GPS. As soon as I got it, I put OpenGD77 on it. I programmed a DMR repeater in Evansville, Indiana (K9EPD) from my home (near Haubstadt). The repeater has a 25 mile range, I am about 20 miles from it. I also got Parrot TG9990 programmed into my HT and upon testing it, Parrot did not repeat my signal. I have changed settings and double-checked them and still nothing. I even went to Evansville yesterday and tested Parrot when I was about 10 miles from the repeater, so the problem isn't range.

I am wondering why I can't do anything on DMR. If you know anything about this, please let me know.

Did you select TS2 for TG9990? TG9 on TS1 should also work. Does the relay respond with a carrier signal after being keyed?
