DSDPlus Trunking

[msingewald]

I am trying to get this going, and I have gotten stuck after just trying to get the control channel decoded. I have FMP24 running on the control channel with a great receive signal, and I launch DSDPlus with it listening to the TCP port and it looks like it should be good but no channel decoding.

Here are the two bat file contents I have so far:

CC-BAT
FMP24 -i1 -o20001 -a1 -P72.0 -f853.75000

CC.BAT
DSDPlus -rc -i20001 -fa -v3 -wsl400.2 -wss100.200 -wel0.1 -wcl0.445 -wes400.520 >>CC.log

Here is the resulting windows. Can anyone see what I could have missed?

change your BW (bandwidth) to 22, use the "B" key

DSD+ doesn't decode 3600 bps Motorola control channels.

Ah, that would explain it. How the heck did you catch that? Thanks for saving me some hair.

I guess I’ll try the newer versions of Unitrunker as I guess he has added P25 decoding.

There aren't very many two level digital signal types to choose from.

Is there a tutorial or instructions for using FMP24 and DSD+? I have looked all over.

I know you need 2 SDRs and you have to run both programs, but thats about it.

^^^ Never mind the above. I found the file 'trunking.txt' which explains it.
