Improved digital voice P25 decoding with DSDPlus

We previously posted about the DSD digital decoding software and it’s usefulness with the RTL-SDR dongle and other signal sources. Now there’s a newly released version known as DSDPlus which promises to deliver improved decoding and clearer audio of unencrypted APCO Project 25 (P25) radio signals.

This program is designed to be used with your RTL-SDR receiver software such as SDR#, with the receiver’s output piped to the DSDPlus program using a program such as Virtual Audio Cable or similar. Unfortunately, DSDPlus is a Windows-only offering at this time, and the anonymous author isn’t releasing the source.

DSDPlus is available for download from MEGA. You can find more the program user guide in the README file.
