DR-1X as Homebrew DMR Repeaters using MMDVM

Homebrew DMR Repeaters using MMDVM

Our club has a DMR-MARC repeater in service. We would like to try the Brandmeister network without making any changes to our existing DMR system. The system using the Arduino Due micro with a ZUM modem board and the Raspberry Pi running the MMDVM Host software. Every time I read about this package I find there is a catch, such as having to use the PI-2 instead of the PI-3. I have both and I prefer the PI-3. There is also reference to a clock kit but no details. Is there any place where I can get step by step instructions about which hardware I need to buy and the software installation for the complete package?

Through a fellow ham i got hold of 2 Motorola MTR2000 repeaters with the plan to convert them to DMR using the MMDVM board made by G4KLX. Here are my notes


Special thanks go out to Graziano IZ5IGB for building the first MMDVM MTR2000 and helping me get started.

S-Cooling dr1x-interface

Microcontroller interface to control operating modes of the Yaesu DR-1X Repeater.

Purpose

Allows remote control of the Yaesu DR-1X Repeater. PTT and operating mode can be controlled remotely via a USB virtual serial port. The squelch input can be sensed using the same serial line.

The code samples the SQL pin and sends information about state changes to the computer. It also sequences outputs for the EXT I/O, MODE, and PTT pins when commanded to.


DR1X Tutorial


This tutorial runs over how to get the DR1X repeater configured for D-STAR operation once you have your Raspberry Pi up and running.

Question : Are you changing a Fusion system to TX in TDMA, or are you just adding a peripheral repeater with the MMDVM that's connected to the system fusion repeater?

Answer : Using the analog side of the DR-1 to connect to a MMDVM.. So now I have a C4FM, DMR, DSTAR Repeater.
