The FA-SDR-TRX is an all-band low-cost software defined radio. The FA-SDR-TRX was created by Harald DL2EWN and described in an article series in the German Ham Radio Magazine Funkamateur. After the big success of the single band kits like Softrock, SDR4080, or Genesis, the FA-SDR-TRX is the next step in the evolution of SDR kits. Thanks to the support of Harald I’m able to provide a detailed description of the concept behind FA-SDR-TRX.
