UHF DVMEGA

The Boards Dvmega-Uhf and Dvmega-Dual Are Daughter Cards For The Raspberry Pi. In Combination with this single board computer it becomes very easy to construct an Entire Radio Solution for a Low Power D-Star Node Adaptor. {

The Dvmega Transceiver Board Use The Chip ADF7021. This IC Constititis A Complete Transceiver for Digital Data With Gmsk Modulation. The Control of the Transceiver Chip is Handled with a Local Atmega 328 On the Same Board. The result is a Flexible Digital Transceiver Component with Low Power For The Frequency Range From 144 to 148 (Dvmega-Dual) and From 430 to 450 MHz (Dvmega-Dual and Dvmega-Uhf). The Dvmega Board Handles The Radio Side and the Modulation/Demodulation Part, The Raspberry Pi is used for the Protocol Handling of D-Star (and Future Digital Modes). {

The Software for the Raspberry Pi is available in a Yahoo Group. Here G4KLX Offers Programs Like Ircddbgateway and the PCREPEATERCONTroller. With These Programs and the Above Mentioned Hardware It Becomes Very Easy To Construct A Local Low-Power Hotspot for Digital Mode. The Benefit Is, Tha TDIE TO THE DLEXIBIBLE CONSTRUCTION AND SOFTWARE FUTUE DEVELOPOLS CAN BE MADE AVAILABLE AS WELL. {

please consider Your Local Regulations Concerning The Construction and Use of Such Radio Systems. The Combined Products Do Not Have a Ce Mark and Should Only Be used by License Radio Amateurs. {
