Unitrunker Unitrunker with DSD+ and two nooelec rtl2838 dongles

[Thorndike113]

I got Unitrunker 1.0.33.6 downloaded and setup according to the tutorial I found online. I am running 2 dongles with VB cable and I have DSD+ decoding the digital. I have everything all set up correctly as I frequently jump back and forth between sdr console and unitrunker and I can hear and decode digital fairly ok on the sdr console. When I listen on Unitrunker, It sounds like its decoding the p25 but at the same time it is sending the digital in with the voice. Is there a way to get rid of the digital? Its definitely coming from the voice end because the control channel stays quiet as it should. Im guessing its got to be a setting I am overlooking.

Let me guess what you're trying to say. You are saying that you are hearing the digital noise overlapping the decoded noise or no?

If so,
Be sure Unitrunker is set to output analog to your sound card.
Be sure digital output is to VBA or Virtual cables whichever you are using.
This setting is found in your Voice receiver window in Unitrunker.
Use my image as a template. Your sound is going to be different. Red rectangle marks where you should be at. Take notice it is Voice receiver.

check your vb cable does not have "listen" checked in Win audio.
check you are not telling DSD+ to send raw audio to speakers

I set it all up that way on my computer and I have no audio at all. Unitrunker is showing on the control channel VCO and the voice VCO that it is picking up the system properly. Everything is displaying good. DSD+ is showing the stream coming off of the control channel and all my sound settings are set to work off of the VB cable. Just no audio. Before I had both the digital sound from the voice end of things (not control channel) along with the decoded digital audio coming through. Windows 10 did an update in the background and now I have no audio coming from the program. I dont see any changes it made to the sound settings. I have to say. SDR and DSD are 100 times worse than trying to program a digital scanner. I can at least listen to the analog broadcast of the Augusta dispatch and watch the data come up as to what unit is what. Unitrunker is and DSD are not user friendly at all.

Im trying to decode and trunk track P25 digital. I have DSD running. The issue is purely audio though because everything else is working fine. Like I said in another posted reply, win10 just did another update so I have gone from ALL (digital audio and decoded digital audio coming through my speakers to now there is none. Nothing has changed as far as the setting in the computer though. I may have to uninstall and reinstall all of this again for the millionth time.

Are you trying to monitor a true P25 system or an older Motorola system that carries digital audio (and maybe some analog audio)?

If it's the former, UT plus DSD+ is the wrong approach.

 

[wowologist]

One question...kinda OT, but are the extra audio utility programs like VBA / Virtual audio cable still needed in Win10? Now that Win10 has audio routing in its core embedded and readily available.

 

[slicerwizard]

All I see are per-application choices for input and output audio devices. If, for example, you wanted to feed audio from SDR# to DSD+, what devices would you pick? You'd only have things like microphone and speakers to choose from, no?

Well its the State Of Maines MSCommnet. Its a Statewide P25 system for state police and a few other agencies that they just switched to back in 2015 I believe. Its type one. To the best of my knowledge, they dont have mixed analog and digital on the system. They do have separate linked repeaters that rebroadcast the dispatches but aside from that, all the police are digital. When I run DSD and SDR console, I can receive the digital all decoded. When I run it through Unitrunker, It went from giving me the digital and the decoded digital from the voice channel all at once. Overnight, win10 decided to do one of their updates and like normal I lost the audio. Audio still works where Unitrunker picks it up and DSD reads it, and I can also change the path for the digital to come straight through the speakers but aside from that, I cant get it to decode the digital and give me a clean decoded voice.

Thats a good question, ive never seen any option for that.

It would be in the sound settings. Where you want the cable to run to. What I have shows audio out and audio in and it will give those same choices for each thing such as vb cable, SDR Console, Unitrunker, etc.

P25 systems don't support analog voice.

As I said, UT plus DSD+ isn't how one should monitor P25 systems. Any one of the latest UT, DSD+ FL, SDRTrunk or OP25 can do the job.

 

[Thorndike113]

The part I am trying to monitor is a type one p25 trunked system. Unitrunker works well, just no audio output. The audio I am trying to listen to is p25 btw

 

[slicerwizard]

Use the newest version of Unitrunker.

 

[air-scan]

@Thorndike113 would you clarify if that system is P25 Phase 1 or Phase 2? Unitrunker won't pass digital output if it is P25 Phase 2. It will pass P25 Phase 1 to digital output. Phase 2 is TDMA which Unitrunker isn't compatible with. At least for version 1. I can't speak for Unitrunker version 2.

 

[slicerwizard]

DB shows it as Phase I only.

 

[Thorndike113]

The system I am listening to is all phase 1. As for the latest version of UT, Where is it found because I searched for it and cant find it anywhere. The best ive found is a ton of sites talking about it and sending you from one link to another. That is, if you are talking about Unitrunker V2. Ive been searching all over the place and have encountered dead link after dead link with a fake google group that says they have it if you sign up with them and there is no link to do so. Haha, I bet the people who design statewide trunked systems dont have even a fraction of the issues I have had just trying to get all this software and hardware working.

hello group, any one have a problem with using 2 sdr dongles for unitrunker? mine used to work , for aq short time, i run windows 10-on a lenova comp

Here is a link to the Unitrunker site, you have to send them an email for permission to join, it might take a day or two for an answer.

Listen to Slicer the latest version UT does not use VB Cable and decodes P25 phase 1 all by itself.
