The hotspot repeater name of 'KK6DCT B' needed to be set EXACTLY in the repeater name setting for the DV memory setting on the radio, otherwise keying up the radio wouldn't even appear on the mmdvm status page and it seems the transmissions are completely ignored by the hotspot (presumably because it's not hearing traffic matching it ...

After setting up the MMDVM duplex hotspot board, it is necessary to adjust the transmit and receive offsets in the MMDVMHost expert editor section. Basically this corrects the transmit (TX) and receive (RX) frequency of the board, if they’re not on frequency.

It runs a Motorola GM300 on transmit and receiving with a Motorola GM340. The coverage south of the M50 is limited and does not match the propagation map. This appears to be due to some high buildings in that direction.Great MMDVM board Time Owned: more than 12 months. We have 5 MMDVM repeaters currently set up, 4 with the Ver-2 pi-hat boards (Red-boards) and 1 with Ver-3 pi-hat board (Blue-board) they are very easy to set up and have great audio. Were are running the boards in DMR, D-Star and NXDN.

240 -120. 94 -125. 50 -130. The STM32-DVM-MTR2K will saturate the MMDVM ADC input at signals much stronger than -30dBm. That's ok, I did that on purpose in order to keep the signal level at the low end up a little higher in order to improve ADC resolution for weaker signals. MMDVM Motorola MTR2000 MTR2K STM32-DVM-MTR2K.

The repeater was originally a complete Bridgecom turnkey MMDVM with mobile duplexer repeater that we ran at full power (40 watts) on a DB420 at 300 feet with no preamp. We just recently converted an MTR2000 to DMR via Pi-Star using the add-in board from RepeaterBuilder. We installed it at the site, turned it to full power (100 watts), added a ...

Hello. My name is Kevin and I am attempting to set up a dmr repeater using your mmdvm repeater kit board and a kenwood TKR-850. I am having problems with the transmit drive level. Even with the TX pot full open and levels set to %100 in mmdvmcal, I cannot get enough drive to suppress the carrier. Do you have any recommendations?

DMR Gateway is a part of the MMDVM_Host suite created by Johnathan Naylor (G4KLX) to add features and functionalities to the DMR side of the MMDVM. If you have never configured a commercial DMR Repeater before, its important to know for the most part, DMR repeaters are "Dumb" devices in the grand scheme of a network.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.Testing began with a Motorola XPR 8400 repeater in analog mode. This repeater is extremely well built, rated 100% duty cycle at full power. Initially I used a Repeater Builder STM32-DVM MMDVM modem board. This board and associated software on the Pi take over as the repeater controller.
