If the audio is clean enough,Maybe you'd be able to pipe it into a PC and run DSD or DSD+...With or without the NAC..DSD will do the work. But Im not sure if the audio coming out of the UV5 will be suitable. Get a patch cord I think its 2.5MM to 3.5MM for the Baofeng..and pipe it into your soundcard. See if DSD can get a good decode rate..Using the old GRE Superconverter I can pick up 800 control channels..But I have radios to monitor,so I never tinkered more..How can I connect to a frequency that is p25 on a Boafeng uv5ra?
