DSDPlus Single Receiver decoding not working

[devicelab]

For the record, I've tried this both with my Airspy Mini and a RTLSDR v3 dongle and both exhibit the same problem.

So I've configured both for R1 monitoring and both seem to start up fine. I can see FMP24 or FMPA working and centered on the frequency, etc. I kick off the 1R or 1RA batch file and all appears working. I can see audio being detected by dsdplus over port 20001 via the blue audio window. But that's it... I'm not getting any decode. Notta. Zip.

I went so far as to set my 1R/A files fixed for P25 only -- (I'm centered on a Phase 2 P25 control channel...) but that didn't help.

From what I've read, I shouldn't need anything configured in any of the support files, correct? (e.g. the .sites, .frequencies or .networks)

Oh I tried disabling my Win10 firewalls but that didn't help. I figured it wouldn't since I can see audio from the dsdplus monitor.

My DSD+ works fine using SDR# in the usual configuration.

Scratching my head...

Since the issue is likely in your setup, posting your batch files would be quite helpful.
I would work on 1 setup at a time and get that working.
For P25 be sure your bandwidth it 12.5 or 9.5

Here is my start up batch file for RTL-SDR. Ignore the START commands and look at each line as if it is it's own configuration file. Follow that example.

START FMP24.exe -rc -i1 -o20001 -P0.0 -g24 -b12.5 -f851.1875

START DSDPlus.exe -r1 -e -T -E -Pwav -i20001 >>1R-log.txt

Single batch file - this works for me,

start FMP24 -i1 -o20002 -f452.2625 -b12.5 -P0 -q1 -g37.2 -_1 -wsl000.00
start DSDPlus -F1 -r1 -e -m1 -i20002 -OM NUL -_3

Then using the L (List feature) you are off to the races.... This one does clear FM/AM and all the digital.

Yeah my batch files were fine. I finally figured it out. The polarity auto detect was disabled by default for whatever reason. As soon as I pressed "P" everything started piping thru and decoding. Geesh.
