TRX DUO APPLICATION BASED HF SDR TRANSCEIVER (RED PIYATA)

Here we take a look at the TRX Duo, a Linux Based SDR Transceiver.

TRX-duo is an SDR device that supports dual-channel physical reception and transmission. It uses 2x16bit ADC LTC2208 to realize direct sampling reception of 10KHz-60MHz. It has the advantages of high dynamic range, high sensitivity, and convenient remote deployment. Using 14bit DAC to achieve dual transmission. The software can be compatible with the famous Red Pitaya SDR, and can be easily used with HDSDR SDR# PowerSDR SDRConsole (V3) and other software
