The MMDVM software is a fabulous development realised by Jonathan G4KLX allowing to built a multimode digital hamradio repeater. Indeed, it can manage the three digtal modes DSTAR,DMR and C4FM. MMDVM is composed of two physical parts.

Transmission lost, total frames: 248, bits: 34968, errors: 2602, BER: 7.44109%. From here, you can find the mean (centre) frequency: (434249800 + 434250800 )/2 = 434250300‬ Hz (300Hz higher than the nominal). Use the “E” command once again and enter your new mean frequency – for me, this was 434250300‬ Hz. e.Post a Comment.

When interfacing an MTR2000 station to ANY external repeater, D-STAR, DMR, or MMDVM controller, make sure you've set the station configuration (Repeater / Base) to BASE so the station looks like a fully independent full duplex receiver and transmitter. This configuration setting removes the internal repeater controller from the audio and PTT paths.The MMDVM 1.0 boards are single turn so you must make very small adjustments. This board uses a multi turn pot. The MMDVM 1.0 boards are single turn so you must make very small adjustments.

When using the RB cable, if the DR-1X successfully decodes a CTCSS or DCS tone, the CTCSS detection line pulls low and disables the STM32_DVM via RXSQ on pin 3 of the Pihat.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.
