A MMDVM is usually a computing device running multiple radios, each of which is used for a separate channel with it's own filters and MMDVM-SDR; MMDVMHost-SDR; QRadioLink; There is also a mirror of all the code on Github. 1/3. The Ham FM Radio app allows the user to quickly tune and listen in to the 144-148, 150-174 and 420-450 MHz ham radio communications via presets. It runs on the Arduino Due, the ST-Micro STM32F1xxx, STM32F4xxx and STM32F7xxx processors, as well as the Teensy 3. Robert used his RTL-SDR, rtl I have 2 MMDVM Hotspot, 1 for simplex using Pi 2 zero adan another 1 is dual hat using Pi 3B. Reply reply     TOPICS. Thank you to James Mainwaring for submitting news about the release of his two new RTL-SDR compatible Android Apps 'Ham FM Radio (RTL-SDR)' and 'ADS-B Radar (RTL-SDR)'. The original code also worked with GNU radio Companion flowgraphs directly, however the new burst timing code is embedded in custom blocks so it's only compatible with qradiolink (an application I wrote for experimentation with GNU RTL-SDR (RTL2832U) and software defined radio news and projects. Thank you to Adrian (YO8RZZ) for writing in and sharing with us his article explaining how to use an SDR to set up a digital voice hotspot for digital voice modes supported by MMDVM such as D-Star, DMR, System Fusion, P25 and NXDN. It supports D-Star, DMR, P25 Phase 1, NXDN, System Fusion, M17, POCSAG, FM, and AX. This operation mode requires a hardware device with support for FPGA timestamps. Adrian notes that this is possible with any full duplex SDR such as the LimeSDR or PlutoSDR, or with a combination of simplex devices, such as a Using GNU Radio and a SDR device as a digital voice hotspot with MMDVM supported modes like DMR, D-Star, YSF. His implementation runs multiple instances of MMDVM-SDR, one instance for each channel. RTL SDR, Airspy, Airspy HF, LimeSDR, HackRF and SDRplay support via USB OTG as well as MMDVM-SDR is slightly different from the original MMDVM software and is tested and developed at MMDVM-SDR on the trunking branch.
