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.Had in test a cheap chinese MMDVM repeater board with a gm340. After long , long hassle i gived up. Even if rx is allmost ok , in tx can't manage to setup...I'm interested in building a DMR repeater with a GP340 and I like the idea of using single frequency as'd save a diplexer and ideally a radio as well. No, you need a duplex hotspot for that. Most MMDVM's fake it. A real repeater can do it, but not an MMDVM. Just for clarity, I'm not talking about the hotspots (although it would be neat to use ...

MMDVM is composed of two physical parts.

I have a STM32-dvm / mmdvm_hs Rasp-Pi 3 Hat GPIO modem from Repeater Builder that I'm trying to figure out. It's either the way MMDVMHost Modem TXInvert or RXInvert is set or it's the pin outs on the radio. I have it connected to a Kenwood TM700 using the 6 pin DIN cable that came with the modem. If I have TXInvert set to 0 and RXInvert set to ...Digital voice repeater could use software to encode and decode and push it out via SignalLink. Is there anything that has to be done via hardware? I understand if you want to decode the AMBE, using a chip is economically better because of patent. But I assume MMDVM repeater doesn't need to decode AMBE, it just passthrough the voice stream.Help with other MMDVM Repeater Boards (with NO onboard RF) 2 posts • Page 1 of 1.

It will decode DMR talk groups on the MOTOTRBO™ repeaters on the C-Bridge network, but it will not decode talk groups on the MMDVM repeater BrandMeister network.

DMR Gateway Explained. DMR Gateway is a part of the MMDVM_Host suite created by Johnathan Naylor (G4KLX) to add features and functionalities to the DMR side of the MMDVM. If you have never configured a commercial DMR Repeater before, its important to know for the most part, DMR repeaters are “Dumb” devices in the grand scheme of a network. 15 Software download. 15.1 RTL-SDR Lite for MMDVM. Welcome to BI7JTA'Wiki for MMDVM.

Otherwise the MMDVM boards are very reliable, and the SD card in the Pi should last a long time if you buy a good name brand one. 2. mike_essAZ.

The STM32-DVM-MTR2K is a joint project between Repeater-Builder and WA0EDA.
