Mmdvm repeater.

The interface to MMDVM_Bridge is the network. This is defined in MMDVM_Bridge.ini. On the mode side, the connection to the outside world depends upon the mode being used. Some modes connect to gateways, others to reflectors and still others to other bridges. Each mode is different and you have to have some knowledge of the networkThough the MMDVM project began in 2015, its code history dates back to 2007. To-date, more than 80% of hotspots/repeaters on the Brandmeister DMR network are utilizing MMDVM, and the number of users that are registered DMR ID members exceeds 250k. Additionally, there are several repositories on GitHub that are part of the MMDVM project.This will be a game changer for many who want to use MMDVM yet maintain a simple setup for their repeaters.

The MMDVM can be networked or work as a local-only repeater. There are many MMDVM based repeaters on the Brandmeister Network. A ham friend of mine has a 2m repeater in VT built from analog mobiles with an MMDVM and supports DMR and P25 (Phase 1) modes in addition to plain old analog. It is on the Brandmeister Network.

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 RB_STM32_DVM is yet another Multi-Mode Digital Voice Modem that gives new life to analog repeaters by allowing them to become digital capable. The STM32 has an on-board microcomputer, so there is no need for a separate Arduino or other processor board. This board, plus a platform running MMDVMHost is all that is required.You will need 2 pcs. One that connects to the MMDVM board that will send data. The other HC-05 (or HC-12) will connect to the display and will receive the data. Only 3 wire connection is needed for one way data transfer.Correct method for adjusting TXLevel #MMDVM_REPEATER Correct method for adjusting TXLevel (Physical adjustment, non software adjustment).

This is why a mmdvm repeater used for DMR should have a 100% duty rating/setup on the transmitter setup.Notice that I also set the RF Hangtime and Net Hangtime to 5 seconds. The hangtime is the amount of time the MMDVM will stay in that mode before allowing other digital mode signals a chance to reach the repeater. RF Hangtime is the amount of time the MMDVM waits after the end of an incoming RF (Radio Frequency) signal.MMDVM Repeater User Case Motorola #MTR2000. IW6BFE.
