MMDVMHOST FM mode implementation - forum

The MMDVM devs intend to include a UDP 'link' interface with the FM controller for other systems to interface with, but any code controlling 'the other side of that' will be left to other devs. Fair enough, it's just that on another hotspot-related forum there are loads of requests for a hotspot that makes an FM radio into a multi-network. README.md. These are the source files for building the MMDVMHost, the program that interfaces to the MMDVM or DVMega on the one side, and a suitable network on the other. It supports D-Star, DMR, P25 Phase 1, NXDN, System Fusion, POCSAG, and FM on the MMDVM, and D-Star, DMR, and System Fusion on the DVMega Installing MMDVM on an STM32F4 NUCLEO board and assembling an interface shield. In this series of posts we take a look at building a Digital Mobile Radio (DMR) repeater for amateur radio use on the 70cm band (UHF). This will be constructed using two surplus mobile analogue (FM) transceivers for uplink and downlink,. 1 Plug out Repeater Hat from Raspberry Pi , 2 Short the BOOTO/3.3V (the upgrade control pin), 3 Connect MicroUSB port to Raspberry Pi, you will enter the RECOVER MODE (Flash Mode), Note: the follow LED long light: PWR, ACT, COS, DMR, POC. 4 Run the flash command: sudo ~/stm32flashV5 -v -w ~/mmdvm_f4.hex -v /dev/ttyUSB0 The MMDVM is a hardware and software component that can interface radios to a computer, like a raspberry pi, turning normal analog radios into digital radios, much like a TNC for packet radio. The MMDVM-Repeater board is a lot like a hotspot, except it doesn't have a radio built onboard

One of the relais switch off the PTT from MMDVM to TX, digitalWrite (RELAIS1, HIGH) ;. The second switch off the sound from MMDVM to TX. digitalWrite (RELAIS2, HIGH) digitalWrite (PTT, HIGH) set PTT from Mic input at the TX. The audio path for FM is from RX out to USB Card Mic and from USB Card sound out to mic in from the TX unit In order to understand the overflow, the FM deviation for each mode must be taken into account: • D-STAR: ~1,2KHz • DMR: ~2,75KHz • C4FM: ~4,5KHz The MMDVMCal works in DMR mode. Once the optimal TXLevel has been found and declared in MMDVM.ini, the Software automatically change the output level according to the modulation implemented

Building a Digital Mobile Radio Repeater Part 1: MMDV

  1. My ICOM ID-4100 DStar has trouble receiving the TX of the MMDVM node. Keeps on shifting from DV to FM with no audio. No issue on RX of the node, I can hear myself on the other hotspots. Saw a similar issue with the DVMEGA, is the problem from the board or the motorola radio? ID4100 cannot RX but can TX. My Kenwood THD74 can RXand T
  2. ator). From MMDVM set TXInvert=0 and RXInvert=1. Note that TX audio gain must be set quite high for DMR to operate properly
  3. In order to understand the overflow, the FM deviation for each mode must be taken into account: D-STAR: ~1,2KHz; DMR: ~2,75KHz; C4FM: ~4,5KHz; The MMDVMCal works in DMR mode. Once the optimal TXLevel has been found and declared in MMDVM.ini, the Software automatically change the output level according to the modulation implemented
  4. If you are still having trouble and running the Pi-Star MMDVM package, try this procedure. Why are there no header pins soldered in JP1? I don't stuff a header in JP1 as it would interfere with the case. (pins stick up too high) My usual method of shorting the pads is to place a pair of tweezers in the two holes and apply power.
