TRX-DUO is SDR radio that supports dual-channel physical reception and transmission. It uses 2x 16-bit ADC LTC2208 for direct sampling of reception in the range of 10kHz - 60MHz. Its advantage is high dynamic range, high sensitivity, and convenient deployment as a remote station. It uses a 14-bit DAC for dual transmission. The software can be compatible with Red Pitaya SDR and can be easily used with HDSDR, SDR# PowerSDR SDRConsole (V3) and other software
