Can't seem to decode digital

So I've managed to get SDR ++ up and running, got the antennas sorted out and trying to get the digital decoding to work. I've got the VB virtual audio cable for the output to DSD Plus, I got it set up so it receives a signal, but I can't seem to hear voice from the digital signals. It was throwing up these error codes. It seems to be getting the signal processed, but is throwing up these codes. These were from around 160mhz and seem to be a continuous broadcast of some sort.

Any ideas? Are these not actual voice channels on the digital modes?

I don't see any voice in there. Second one looks like an NXDN control channel - not going to find voice on that.

Using a virtual audio cable is just asking for trouble. Should be using one of the FMP programs, if possible.

Focus on your event log window. When voice activity is decoded you'll see it in bright green while active and darker green when archived (Reference below). VB cables work fine to decode conventional digital transmissions but for anything trunked, launch one of the FMP bats.

Also in SDR++ you'll want to make sure your bandwidth is set for what you're listening to. I found 8000 works good for DMR where for NEXEDGE48 you'll want a narrower setting like 4000. Of course the stronger the signal the better the decode1739116828212.png
