Its been a LONG time since I used this and need some help. I DO have the program working as far as installed (did copy .dll files over into DSDPlus folder) and seems to "run" but I don't remember how to set it up for listening to agencies. I have SDR Sharp all configured and running, using VB audio cable. Here is a DMR trunked site I want to check out: Scituate Site Details (OneVoice Network) I put control freq in SDR SHARP but got this error. I know I am missing some steps. I remember some VERY confusing text files to configure for trunking systems. Here is my local P25 simulcast site: Metro Prov which I would like to test out too. And lastly, an NXDN system: Johnston Site Details (Data Radio Management (NXDN)) I vaguely remember having to start a few batch files to get DSDPlus to stat decoding....but the editing of those files was very difficult to understand the syntax used. Since I last used this program, there have been more DMR and NXDN activity in the area. I am using an RTL-SDR dongle hooked up to an OMNI-X antenna. PC is an HP Z420 with 32GB RAM and a XEON processor.
