SDRTrunk P25 Phase II testing

[DRL-XM43]

I am currently running the latest beta of SDRTrunk with P25 phase II decode capability.

It is performing perfectly on two P25 phase II sites.

I caution this version is in the early stage of development. It is multi platform Java system developed by Denny.

Thank you Denny for all your hard work!!!!

Is this version of sdrtrunk up anywhere or is it private? Github only has the latest alpha releases

It's not a release. Denny's latest commits make possible the decoding of Phase II voice.
Get the 296-p35-phase-2-decoder branch of SDRTrunk and
the 5-ambe-codec-2 branch of the AMBE decoder.
Build both (easy process), configure and monitor.

I'm not sure i understand the "build" process, can you help me a little please?

Hello-

At the projects' Github links above, scroll down - there are instructions on how to build with Java 11 and the included 'gradle' scripts for Linux and Windows.

 

[DRL-XM43]

Denny provided the information at the sdrtrunk google group.

There are also discussions and help there.

Redirecting to Google Groups

P25 Phase2, awesome! Long desired. I downloaded the branches, compiled and have the program running.

Phase 1. It doesn't want to stream, even though it connected to icecast2 and the audio is listed in the aliases and I have talkgroup range 1-65535 to capture everything. I must be doing something wrong, but I have yet to find it, comparing with an older version of sdrtrunk.

Phase 2. The two channels are showing as IDLE. I have it set to auto determine the NAC, etc.

Is the google group private? when I search for it google can't find it.

I am trying it on an rPi4 and AtomicPi and running it on a rPi3+

How does one do this? I have sdr-trunk-all-0.4.0-alpha.1 .jar that click and it runs.

I downloaded sdr-trunk-0.4.0-alpha.9-windows-x64 and am lost. It also does not have a jar file to click like I have been doing.

I downloaded sdrtrunk-296-p25-phase-2-decoder and when I click gradlew.bat, a window opens then closes..

I was never good with java.

 

[dave3825]

My bad. I found sdr-trunk.bat in the sdr-trunk-0.4.0-alpha.9-windows-x64 bin folder and sdr trunk does start. Still unclear where or what to do with sdrtrunk-296-p25-phase-2-decoder . I cmd into that folder and ran
gradlew.bat clean buildSdr and get the following,

C:\Users\Preferred Customer\SDRTrunk\sdrtrunk-296-p25-phase-2-decoder\sdrtrunk-2
96-p25-phase-2-decoder>gradlew.bat clean buildSdr

Not sure what's going on as sdr-trunk-0.4.0-alpha.9-windows-x64 sdr-trunk.bat works fine and p[lays audio. I know I am doing something wrong but do not know what....

in system variables

Is what is in mine.

I figured out my non streaming issue. It will now stream Phase 1.
Phase 2 is still showing IDLE. and the NAC, etc. field are blank even with auto populate checked. I must be doing something basic wrong. I can see the phase 2 frequency in the waterfall.
I am using jmbe-1.0.0.

If you are decoding a phase II trunk, select the phase 1 decoder, it will recognize the the P2 and decode it.

The phase 2 decoder is only for decoding a single phase II channel and will not work on a control channel.

The best place for info is here Google Groups at the support group.

I am not sure what you are doing but go to the branch you desire, download the zip file, uncompress and then follow the compile instructions you will wind up with an executable jar file after the compile (windows or Linux) the instructions for this are scoll down on the page.

The easy way is to open a command window, cd to the decompressed folder, then execute the appropriate compile bat from there.

Thank you for this. I will try it.

When I go to that link, even while logged into my google account I get a

Mine says ,




I thought it was stated on one of the pages that you did not need java anymore as it was included in the download. Either way, not sure what to set it to as sdr trunk is working the way with java set like the pic. Just can't get past,

C:\Users\Preferred Customer\SDRTrunk\sdrtrunk-296-p25-phase-2-decoder\sdrtrunk-2
