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/
Currently the following DV modes are supported:
To utilize the DVMega hotspot, a transceiver capable of the selected DV mode is necessary to operate as the hotspot only provides a gateway into the selected infrastructure. The DV-MEGA has only one time slot.
