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.Re: mmdvm vs DStarRepeater mode. by M1DNS » Mon Sep 21, 2020 8:23 pm. Depends on the hardware used. For MMDVM boards use a mmdvmhost setup. For earlier generation or legacy hardware such like DSTAR gmsk boards, dvrptr cards, dvap, original dvmega etc. use a Dstarrepeater setup. Sent from my SM-G935F using Tapatalk. Andrew M1DNS.

The MTR2000 is an analog repeater, and has no native support for DMR or any other analog mode. (The MTR3000 _does_ support DMR in some configurations, it seems.)

You would use a hotspot when you either don't have a DMR repeater nearby, or simply don't want to tie it up for any length of time. Many hotspots are capable of multiple modes as well, such as D-Star, P25, DMR+, YSF and NXDN… but we are only going to talk about ...DMRDelay is how you tell MMDVM about this delay so that the subscriber can properly synchronize to the repeater. It appears the XPR8400 has a similar receive architecture. I re-tested D-STAR and got the RX pots optimized. Then testing DMR, I started with DMRdelay of 165 and walked down to 1 55.The MMDVM-Repeater board is a lot like a hotspot, except it doesn't have a radio built onboard. Instead, it uses cables to wire directly into the IO pins of the radio(s) you choose. The MMDVM/Raspberry-Pi combo will turn a single analog radio into a high powered hotspot or 2 radios into a fully featured digital voice repeater. The MMDVM_Host ...

More importantly - restarting the repeater is fine - after the restart it works locally with no problem on TG9! I have not tested the WiFi option yet, but it looks like as long as the MMDVM board gets the IP address assigned, the system works fine locally on TG9!

This is the source code of the MMDVM firmware that supports D-Star, DMR, System Fusion, P25, NXDN, M17, POCSAG, AX.25, and FM modes. It runs on the Arduino Due, the ST-Micro STM32F4xxx and STM32F7xxx processors, as well as the Teensy 3.5/3.6.

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 more like the other modes.I even tried a different radio thinking it might be the radio is not transmitting.
