DSDPlus Fast Lane - P25 - 2 RTL-SDRs - No audio output

[JasperRidley]

Hey All!

First post here and I feel bad but I really feel like all the information posted here has me 99.9% there finally. I know this topic has been beat to death but I'm stuck.

I'm trying to decode P25 here in Lake County , IN Lake County Public Safety Trunking System, Countywide, Indiana - Scanner Frequencies

I have 2 - V3 RTL-SDRs

Paid version of DSDPlus Fastlane , DSDPlus 1 .101 and the posted .dll's

Does anybody see where I've gone wrong? I'm new to SDR and off air signals in general for what it's worth.

Thanks for any help!!

Not sure if that picture can be seen properly so here's a link.

I would try it with one dongle.

If it helps to try here is a single batch file you can make using the 2 lines.

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

you need to adjust for your dongle #, PPM gain and CC frequency

name the bat anything you like.

It may be worth a try for a fast start.

Thank you!!

Well..... That was easy for you! That worked instantly! I wonder if my gain was too high?

In your screen shot, it says Select VC DSD+, so you've frozen your copy of VC DSD+...

Hmmmmm I see that now, let me try again. Freezing it is just clicking on the DSD+ window?

Thank you! This whole time I've been doing this with that window frozen! Once I clicked it it started right up.

Now to create a batch file like DRL-XM43 suggestion above.

I'm getting some a slight "digital breakup/clipping" on some of the transmissions. Is this normal or possibly more fine tuning on my end?

Sorry I'm not sure how to name the issue so I just related it to my CATV world.

Here is a small example.

Thanks again for your time guys!!!
