FA-SDR-TRX part #1 – Systems View

FA-SDR-TRX-Software-Defined-Radio-PCBThe FA-SDR-TRX is an allband low cost software defined radio.

In 2007 several SDR (Software Defined Radio) kits became available for Ham Radio purpose. Since most of these kits are just single band receivers, another easy solution was needed to benefit from the PC based Signal Processing on multiple bands.

This article documents the performed analysis and conducted work necessary to perform this modification.
