Decoding D-STAR headers with the RTL-SDR

Posted on Friday, September 27th, 2013 in digital radio data, RF, SDR by the machinegeek


D-STAR or Digital Smart Technologies for Amateur Radio is a digital voice and data protocol used in amateur radio. Here’s a link which shows how the RTL-SDR can decode D-STAR text messages and headers (link is in Italian but Google translate can help, and the pictures show more than enough information). By using SDRSharp and stereo mix you can tune to a D-STAR signal, and pass the audio to a command line based decoding program (dstar.exe) which, which will then decode D-STAR text messages.

    Until the major radio manufacturers implement compatibility between brands using an open protocol I won’t be buying. Yaesu recently released the FT1D that uses yet another proprietary protocol.

    Cool demo but I hope D-STAR dies.
