Overview

The DV-MEGA is a family of add-on boards (shields) for Arduino Uno, Arduino MEGA and Raspberry Pi for several digital voice communication standards.
DV-MEGA is produced by Guus van Dooren PE1PLM, http://www.dvmega.auria.nl/

DBR UNO.png

Currently supported are the following DV modes:

  • D-Star
  • DMR+
  • DMR BrandMeister


To communicate via such a hotspot, a transceiver capable of the used DV mode is necessary to operate, the hotspot provides only an access gateway to the selected infrastructure. The DV-MEGA has only one time slot. At the moment (april, 2016), the subscription on BM is dynamic and valid for 15 minutes.

Functionality

  • Private call
  • Group call

Soon

  • SMS

Mode of work

  • DVMEGA + Raspberry PI + the MMDVMhost application [1]
  • DVMEGA + Raspberry PI + the BlueDV application [2] for Android via ser2net in a hotspot mode wifi connection

Hardware

Three different hardware configurations of DV-MEGA are currently available:

  • Dualband radioshield - Arduino UNO based Support for D-Star and DMR
  • Dualband radioshield - Arduino MEGA based Support for D-Star and DMR
  • RPi radioshield - Raspberry PI based Support for D-Star and DMR
  • RPi radioshield - Orange Pi[5] based Support for D-Star and DMR

Software

  • dmrlib (highly experimental, for developers only)
  • BlueDV [6]
  • BlueSpot [7]
  • MMDVMHost [8]

RaspberryPi Image

This is a list of ready to use SD-Card images. Please append your URL.

  • easyBM [9] A lightweight Image with an webbased configuration tool.
  • easy-DVMega [10] is a raspbian Jessie image with a complete configuration to be used on a Raspberry Pi with the DVMEGA shield.
  • 20160505_R2AJV-raspbian-jessie_lite-VNC-LXDE-DVMEGA_MMDVMHost - the mage based on Raspbian Jessie Lite to build a hotspot nodes D-Star and DMR using the MMDVMHost application. Requires a 4GB SD card. Login pi, password raspberry, VNC port 5901.
