Description

The SoftRock-40 is a small, low-cost, good performing 40-meter "software defined radio" receiver that plugs into a computer USB port and delivers I-Q audio signals to the computer's sound card. It was designed by Tony Parks, KB9YIG and Bill Tracey, KD5TFD as an "SDR sampler project" for hams everywhere to easily try out software defined radio.

This is the place to express your enthusiasm, ideas, experiences, modifications, extensions and maybe more ?
