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.

4/26/20 #191. Hi Folks. As you may be aware an FM repeater controller has been added to the MMDVM. Most of the processing is done in the firmware with the host only providing the initialisation information, which is different from how the other modes operate. At some stage, we will be offering network access to the repeater and then it'll be ... mmdvm The Multi-Mode Digital Voice Modem is a combined hardware and software development of a modem to handle all amateur digital voice modes. Initially it will support D-Star and DMR, with System Fusion and P.25 coming later, as well as a built-in FM repeater controller. We are using a Yaesu DR-1X repeater with an MMDVM KI6ZUM radio pcb for raspberry pi board plugged into the rear 15w HD connector of the DR-1X. The MMDVM is run by a tiny Raspberry Pi 4 computer with the Pi-Star image installed. You can now operate through GB7IT on 439.5125 MHz with a -9 MHz TX shift using DMR.

HB9EUE-3 cannot be found on APRS. And this is the Callsign configured in MMDVMHost for my repeater. What I was suggesting, is adding a way to optionally publish the coordinates of the repeater, those which are configured in the ini file of MMDVMHost, to APRS. Those are in a defined format. STEP 2.

So, in case of C4FM, the output level is automatically set at twice the level previously found by MMDVMCal in DMR mode. The bad news is that MMDVM, in C4FM, gives the warning "DAC has overflow" if the TXlevel is greater than 60% (whic is a 120% in C4FM, effectiverly), although the TX trimpot is at maximum level.The repeater-builder web group (mailing list) that is associated with this web site has over 5,500 members worldwide and is a tremendous resource of technical knowledge on repeaters and repeater-building, be they amateur, commercial, GMRS, public safety, CAP, or ...
