April 26, 2018 ·. New Repeater-Builder STM32-DVM V3 now available. After much ado, the new Repeater-Builder STM32-DVM V3 "The BLUE board" is now available. I have been working the past few days to get enough boards built to fill all of the pre-orders. Thank you to those folks that had faith in my ability to produce an NXDN compatible board.
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.K6PUW Multimode DV Repeater Welcome to California's first Wide area coverage MMDVM Digital Voice Multimode Repeater AFFILIATED WITH THE "KINGS OF DIGITAL" Covering Los Angeles and parts of Ventura, Riverside, San Bernardino and Orange Counties Please donate to help support this special Read More ...The process will be the following: Modification of the MD380: In order to transmit M17 audio, the radio needs to be modified so the MCU has direct access to the mic without the audio being routed over the HR_C5000.

This means that you can easily unlink from a busy talkgroup even when the hams using the TG don't leave gaps between their transmissions. Another advantage of the duplex boards is that you ...Once the firmware has been loaded, you will need to add some extra information to your MMDVM.ini, or use the one in GitHub as a basis for your system. In the Modem section the TXLevel and RXLevel values also apply to the FM repeater. Like the other modes, it is possible to override the TXLevel parameter for FM only with an optional FMTXLevel ...

From DL5DI’s description: “The MMDVM is intended to be an open-source Multi-Mode Digital Voice Modem, which utilities the power of an ARM processor and a simple analogue interface board. The Multi-Mode Digital Voice Modem is a combined hardware and software development of a modem to handle all amateur digital voice modes.”. The open ...To update the firmware within PiStar execute the following commands: $ rpi-rw. $ pistar-mmdvmhshatflash hs_dual_hat. If you have a board equipped with 12.288MHz TCXO you have to flash the according firmware type using: $ pistar-mmdvmhshatflash hs_dual_hat-12mhz.This lead to the creation and documentation of M17 packet modes and a KISS interface for M17 packet and streaming modes. Packet mode operates at a base rate of 5kbps, with typical throughput of 3.6-4.8kbps. These TNCs work with 9600-baud capable radios. Steve KC1AWV has been testing APRS over M17 for a couple of weeks.MMDVM Passwords and Servers Updates. This is a major pre-announcement; our effort to develop a more robust MMDVM server authentication system. This work has been in development for better than a year, off and on as time was available. It involved a number of people to envision, concept, collaborate, develop, implement and test.

Years ago ~2015/2016 on duplex (repeater) mmdvm use I discovered a DMR 10s TX hangtime combined with 10s mode hangtime was the optimum setup, with no dmr key issues between overs, as it was already txing, waiting for the rx to fill empty slots. This is why a mmdvm repeater used for DMR should have a 100% duty rating/setup on the transmitter setup.For preview, more settings guide please follow my YouTube , I will update again.MCS2000 pinout sane as GM1200.The MMDVM repeater board and cable, obtain from...
