My single channel P25 decode mystery

[old7...@gmail.com]

I have a playlist with 12 local single channel P25 services.

I noticed that 2 of them seem not to be decoding.

I started monitoring on my scanner and it was hearing them just fine.

I then fired up DSD-Plus and monitored one of the two.

Solid decode and event log showed both radio id and talkgroup id.

I then checked the other one with the same results.

Next I put my R8500 on each one and fed to an AR300 digital decoder and both had good audio.

Next I plugged both in to a new channel config with the FM decoder to see how clear the noise was when there was a transmission.

My SDR-Play DX was hearing them just fine.

Not sure why sdr-trunk isn’t decoding audio.

I tested with the last release V0.6.1.

Then with the nightly build from last week and got the same results.

The other 10 channels are decoding without any problems.

There might be a way to record the input signal but as I mentioned in my introduction I can’t access all the functions and that includes setting recording parameters.

If anyone has any ideas on how to figure out why these channels don’t work I’d appreciate it.

Also if there are parameters I can set via .xml keys in the playlist to help get better data that would also be great.

tnx
