A 2m fm bench test of the Avatar Software Defined Radio. It consists of a wifi enabled vhf/uhf up-down converter and the GNU Radio 3.2 core ported to Android running on a Droid 2 with version 2.3 os. The software defined radio hardware is designed for all-mode use across 2m, 70cm and optionally the 220Mhz or 900Mhz bands. The Avatar SDR processor is a Microchip dsPIC33 and although capable of performing both modulation and demodulation is only used for tcpip stack functions, data compression across the wifi and controller functions. All software defined radio tasks are executed on the Avatar SDR client running on the Android hardware(Droid 2). The client used in this video is very minimal and serves only to illustrate the proof-of-concept. A much more sophisticated interface is in development that will offer prepacked modulation schemes along with a tool similar to GRC to facilitate interactively wiring your own. Development of the up-down converter is ongoing with a stable beta quality design expected to be ready by mid April 2014.
