Unitrunker Unitrunker 2.1

[maus92]

Can you provide a screenshot of a "ghost channel" and where you see it? Bad decodes often get promoted as a channel; I routinely get them on our local L3H system and either present as 000.0000 or random / out of band channels depending on band plan. I assume the channel number sent on the control channel is being corrupted and is not being corrected by "built-in" error correction. It seems to be weather sensitive as it appears in random cycles. The in-range Moto systems rarely present this problem.

Hi, Rick

This post is about Harris Regrouping on the Saskatchewan PPSTN.

Reading post #139 by maus92, where he "believed" he was seeing "Simulselect" patching on his local L3H P25 system,
I think it is time for us to have a close look at the GRG, as decoded by Unitrunker 2.

We will be looking at the Octet=2=GRG.

I found that Unitrunker 2.1.0.108 is not displaying the Regroups correctly.

Octet 0=opcode=BO=1011 0000=SUP GRP PCH.
Octet 1=MFID=A4=1010 0100=Harris.
Octet 2=GRG, see the bits in the GRG.
Reads: right Bit is 0 to left most Bit is 7.

When Bit 7 of the GRG is "1" it is a One-way Regroup (Simulselect).

E1=1110 0001
E2=1110 0010
E3=1110 0011
E4=1110 0100
E5=1110 0101
E6=1110 0110

Thanks to maus92 and thank you Rick for all that you do!

It would be great if the program could correctly display the type of Regroup in use.
A one-way Simulselect or two-way Multiselect Regroup.


Cheers!

[Unitrunker2]

I found that Unitrunker 2.1.0.108 is not displaying the Regroups correctly.

When Bit 7 of the GRG is "1" it is a One-way Regroup (Simulselect).

Here is what's going on. There are four relevant terms - with overlapping but different meanings.

1. Patch
2. Regroup or Dynamic Regroup
3. Multiselect
4. Simuselect

Their exact meaning varies based on who does the talking / writing. Here's an example.

https://www.cisa.gov/sites/default/files/video/22_0228_fpic_p25_issi-cssi-features-functions_patching-dynamic-regrouping_508C.pdf

I adopted the term "multiselect" years ago for this peculiar type of patch - because that's what Motorola called them. Please consider this a synonym for "simuselect".

In L3Harris documents, they seem to like the term simuselect. In the PDF above, someone at cisa.gov also seems to like simuselect. The L3Harris docs use a broader / looser definition of dynamic regroup. I use this term when a subscriber's radio is forcibly moved to a different talkgroup than where the radio's channel select knob sits. This is different from a patch or multiselect where whole groups of radios are subsumed by another group.

You can expect different software to use different terms. I use the word site where other programs use the word tower.

Yes, the program is showing the Harris GRG as Multiselect when it is in fact Simulselect and the
program is also showing Harris Patch Super when in fact it is Multiselect.
The system is Harris=A4 so their "terms" should be used for their A4 messages.

Multiselect is a two-way regroup.
Simulselect is a one-way regroup.

The program should display Harris "terms" for Harris=A4 messages and not those used by Motorola=90.

There are 2 different types of patches on this system and the program should display the type in use so
that we will know if the SG-patch in use is one or two-way.

Cheers to you Rick!

Can you show us how these two types of patches appear to you in the Site window Calls tab?

When double clicking on a talkgroup, what's the difference between selecting "Info / Ignore" or "Listen / Lockout"? I want to see the talkgroup but not hear it.

Hi, Rick

Calls window screen shots for you.

See the screen shot: Multiselect May-15-2024.

Remember when octet 2 is from 60 to 7F it is a Multiselect (activate)
Remember when octet 2 is from 40 to 5F it is a Multiselect (deactivate)

Third patch, octet 2=GRG=69=Multiselect (activate)
08:38:00.619 047 7 -B0 A4 69 07 F6 00 37 84 00 0E 98 C9 Harris Patch Super 07F6 adds G 000E sequence 9 algid 84 keyid 0037

There are no Simulselect seen in this screen shot.
Remember when octet 2 is from E0 to FF it is a Simulselect (activate)
Remember when octet 2 is from C0 to DF it is a Simulselect (deactivate)


Simulselect one way regroup screen shot:
In the screen shot Simulselect one-way regroup, we do not see any EMS RID channel grants, as this is a one-way regroup.
But there is a problem the PPSTN has not been able to solve, as all the EMS radios are Motorola and
they do not respond to the Harris A4 regroup commands from the network. An EMT told me that he will
never ask a dispatcher for a patch because, "Those radio patches do not work"

In the screen shot Multiselect two-way, we see the RCMP Harris RIDs and their channel grants, but there are
no provincial policing Motorola RID channel grants seen because they are not responding to the
Harris A4 regroup commands from the network. Two RCMP talk-groups ID 10 and ID 26 with the key ID 39
and one provincial policing talk-group ID 6225 with the key ID 6915 are being regrouped, key ID 37.

I have turned logging on and will get more screen shots.

Cheers!




To:
W4KRR,
After double clicking on the talk-group go down to Listen/Lockout/False
Click on False and change to True.

Enjoy the silence!

 

[Unitrunker2]

When double clicking on a talkgroup, what's the difference between selecting "Info / Ignore" or "Listen / Lockout"? I want to see the talkgroup but not hear it.

The "Ignore" is for the RR DB download. If you don't want the next download to overwrite a specific talk group, set Ignore to True.

To prevent a voice role VFO from following a specific group in a call, you can do any of the following:

1. do as @Mobby1-Kenobby suggests and set Lockout to True.
2. set the Rank to a number larger than your voice VFO's listening threshold (for example: 99).
3. if your voice role VFO has a listening address tag, make sure the unwanted group's tag is blank or otherwise does not match the address tag in the voice role VFO.

 

[Unitrunker2]

Here's a minor update to what SDRs are supported by the program:

• Airspy Mini,
• Airspy R0/R2,
• HackRF One or clone,
• Realtek with an R820T, R820T2, or R860 tuner.
• Realtek with an R828D tuner at 28.8 MHz (the RTL-SDR.com BLOG V4).

Hey guys, I was wondering if someone would fill me in on what the "PXP" service is, i understand the "P4" and stuff but haven't been able to find anything on this "PXP".

Thanks!

P = protected, XP = cross patch. That's an encrypted call to a patched super group.

This is kind of a random issue... I recently updated my computer that I was using for SDR and although I backed up my %appdata%\Unitrunker directory, and that was working okay after restoring it and using it, I thought I might get a fresh start on all my configs so I removed that "Unitrunker" folder, ran the app, and started a basic config of a local system. No issues there.

Then I went to compare the new XML files with my old ones because I was curious, and lo and behold, that Unitrunker directory didn't exist. And yet, if I relaunched the app, all my config info was there. So where in the heck was it saving those files?

I fired up the trusty "Process Monitor" app and watched Unitrunker run and saw that it decided C:\Windows\system32 was as good a place as any to save those new XML files. I didn't specifically run the app as an admin, but I do have my admin approval turned off on my system (yes, bad, I know) otherwise it would/should have prompted me since it was trying to save files in a protected location.

Long story short, it seems like if %appdata%\Unitrunker does not exist, it will default to that strange behavior, saving the files to the System32 folder. Manually creating an empty folder under appdata fixed it (and moving those files out of system32 that it created).

I guess this is my way of saying there's a bug... I figured it would create a new Unitrunker folder if it wasn't there. It must create it during the install but if it runs and sees it's not there, it's just using system32 which I think is the default folder location for something running under admin rights (like if you run cmd.exe as an admin, that'll be your default folder usually).

A little strange, but I wanted to mention it because I couldn't find anyone else talking about it when searching, and it certainly had me stumped for a good 20 minutes.

Thanks @mpbradio. You probably have the following warning message in your Journal tab.

Warning: elevated priviledges unnecessary.

I'll add your suggestion to the backlog.

You're probably right... when I did finally realize those files were in the system32 folder, I saw the journal log file in there but didn't think to check in the app window itself to see what was happening.
