I am learning my way around SDR by trying to scan Connecticut State Police using DSD+ Fastlane 2.18 only (I had a setup using Unitrunker which I used to get LCNs associated with the voice frequencies for creation of the DSDPlus.frequencies file but I am not sure I am using that correctly).

First, is that possible? I read on the Scan-NE website that it is a P25 Smartnet system so have setup the DSDPlus.frequencies file with:
P25, 4B16, 006, 2, 852.65000, 0.0, 0
P25, 4B16, 006, 8, 851.21250, 0.0, 0
P25, 4B16, 006, 17, 851.43750, 0.0, 0
P25, 4B16, 006, 50, 852.26250, 0.0, 0
P25, 4B16, 006, 95, 853.38750, 0.0, 0
P25, 4B16, 006, 116, 853.91250, 0.0, 0
P25, 4B16, 006, 319, 858.98750, 0.0, 0
P25, 4B16, 006, 505, 863.63750, 0.0, 0

I got the 4th column from Unitrunker which shows those numbers as “LCN” – I’m not sure it is correct as the “OTAchannelNumber”. I included the frequencies in the “TXFrequency” column and put “0.0” in the “RXFrequency” column – not sure if that is correct either.

I then start FMP24-CC.bat which contains:
FMP24 -rc -i1 -o20001 -P-0.346 -g36.4 -f853.9125

followed by CC.bat which contains:
DSDPlus -rc -i20001 -v3 -wsl400.2 -wss100.200 -wel0.1 -wcl0.445 -wes400.520 >>CC.log

As far as I can tell, the FMP24-CC.bat output looks ok but the DSD+ CC Channel Activity window shows no activity.

If anyone is successfully using DSD+ 2.18 and can point me in the right direction I would greatly appreciate your help.

Thanks

Glenn

It is a combination system but the bulk of the CSP communications is still on the older portion of the system. It is analog control channel and P25 voice. You need to use TRUNK88 or UniTrunker for the control channel trunktracking and DSDPlus for the voice decoding.
You can use DSDPlus for the 700MHz P25 trunking part of the system.

Thanks Chris. I will look for a more straightforward system to gain familiarity with the "all in one" capabilities of DSDPlus 2.18.

I will also take a look at Trunker88.

I appreciate the guidance.
