Mmdvm repeater.

From the radio, must set radio to use EXT. DATA SPEED = 9600 bps and use 6-pin Mini DIN cable as specified by RepeaterBuilder.org (pin 4 "PR9" is audio output before discriminator). From MMDVM set TXInvert=0 and RXInvert=1. Note that TX audio gain must be set quite high for DMR to operate properly.

In the next series of articles, I will describe how I mounted two TYT-TH9000(D) radios in a 19 inch rack shelf, built a common repeater controller interface, added supplementary cooling to the transmitter and tested the complete repeater with two different controllers.The MTR2000 is an analog repeater, and has no native support for DMR or any other analog mode. (The MTR3000 _does_ support DMR in some configurations, it seems.) Using something like the MMDVM, you could build your own. But I've just learned of the STM32-DVM-MTR2K, which is an MMDVM board that sits in the card cage!The MMDVM will not connect to any dstar system.

My other hotspot works 100% on the same home network. You do not have the required permissions to view the ...Notice that I also set the RF Hangtime and Net Hangtime to 5 seconds. The hangtime is the amount of time the MMDVM will stay in that mode before allowing other digital mode signals a chance to reach the repeater. RF Hangtime is the amount of time the MMDVM waits after the end of an incoming RF (Radio Frequency) signal.Dynamic talkgroups are not connected during normal operations but, by keying up your radio and assuming it isn't blocked out, it will connect for 15 minutes and act like a static talkgroup. Every time you key up, it resets the 15 minute timer. After 15 minutes, it's disconnects from the talkgroup.
