The Shopping List for your Home-Brew MMDVM Repeater
Interfacing the MMDVM to a pair of CDM 1250 Uhf Radios By: Mark K Ward N6IB The Shopping List for your Home-Brew MMDVM Repeater Project using Motorola CDM 1250 Uhf radios Before we attempt getting started on this project, you will first need go shopping for a few Interfacing the CDM 1250 Radios with the MMDVM Modem this is the wiring
Instructions and Diagram for Interfacing the STM32_DVM DMR
I have received numerous requests for detailed instructions and information on how I converted the Yaesu DR-1X Fusion repeater to a repeater capable of doing DMR, D-Star, C4FM (Fusion), P25, NXDN, or any combination of these digital modes by using Scott Zimmerman’s excellent and powerful STM32_DVM board running on a Raspberry Pi with the Pi-Star software.

Build your MMDVM Hotspot yourself - F5UII
Intro. After the online resources to mount its full duplex MMDVM digital repeater based on Arduino and Nucleo STM32F4, here is the time to explain how to set up a “homemade” access point (Hotspot) MMDVM based on a few simple elements:. A “STM32Duino” board based on STM32F103 CPU, which we will program with MMDVM (firmware); A RF transmitter/receiver UHF RF7021SE (ADF7021) circuit

Another MMDVM project in the works is connecting to the FCS servers for Fusion. The FCS servers are used by DV4mini and Openspot and now we will have access to them from MMDVM. This is still in beta but will be part of main MMDVM/Pi-Star soon. For FCS the "Group" can be selected by DTMF on your Fusion radio. eg: "A199" gives you the ECHO
GitHub - juribeparada/MMDVM_HS: MMDVM HotSpot: firmware
Jun 02, 2019This is the source code of ZUMspot/MMDVM_HS firmware for personal hotspots (ADF7021 version of the MMDVM firmware), based on Jonathan G4KLX's MMDVM software. This firmware supports D-Star, DMR, System Fusion, P25 and NXDN digital voice modes and POCSAG 1200 pager protocol. This software is intended
