ARCXT: DMR Tier 3 Sleuthing?

[sunwave]

I was pondering a way to search and find NAC and Color Codes for a local DMR T3 system. I tried programming this system using RRDB data but once scanning resumed after the programming nothing heard. I had to wipe the system off then reprogram as DMR single frequency conventional for each listed frequency for this system. Then I heard traffic on those listed frequencies.

My goal is to be able to "HOLD" on any talk group at a given time. Can't do that whilst the DMR system is programmed as single frequency conventional. I thought maybe ARC XT Pro might be able to assist in some way to find the NAC and Color Code. Scanner is BCD325P2. My knowledge is none on DMR T3. I done this before for a CAP+ system in DSD+FL but the two work differently. I no longer use DSD+FL nor any other computer based trunking software. (I reserve my SDR's for HF reception.)

I have never done this kind of system sleuthing using a DMA scanner before. Unknowns are difficult to sleuth.

I have ARC XT PRO and Basic both paid full versions.

Link to said system?

NAC is only applicable to P25.

You'll need to find a way to determine correct LCNs if you feel the RRDB is inaccurate so the system can be properly tracked. DSD+ Fast Lane will give you the LSNs / channel IDs per frequency & you can then use this LCN calculator to determine the correct LCNs and compare them with what's RRDB listed

I feel the RRDB is inaccurate because I heard nothing when the scanner was programmed as RRDB showed. I heard traffic programmed in conventional single frequency mode. I no longer have the DSD+FL files. Nor my DSD+FL password. I still have the SDR's. Ithought maybe the scanner will display the LCN's.

For that at the minimum you'd need a BCD436HP to run LCN finder. No way to do it with a 325p2

Oh ARC XT Pro imported it like this

That don't look right. Perhaps maybe why I can't hear anything programmed from RRDB? Chickasaw Personal Communications Site: Edmond

@sunwave have you tried programming in the frequencies as conventional and see the results you get? Sounds like a good job for an inexpensive SDR dongle and free (or low cost) software.

I really don't want to use those. I felt tied down to the pc listening to traffic. I am guessing try to correct the import with what RRDB showed. ARC XT Pro didn't import them correctly @Butelsoftware.

Here's how it's imported using ProScan

I usually do not spend time listening to the traffic on the SDR, but I'm using DSD+FL paid version ($10 yr or $25 for life) to decode systems, fine the type of signal, LCNs, NACs, Color Codes, and even OTA aliases. It is a source of a lot of information that helps me to program my scanners and G5 pager.

Here's how it's imported in ProScan

We all know about the OP's "issue" with Proscan

But yeah, program the LCNs as they're listed in the RRDB & as Bob outlined in post #10. Let us know if this takes care of the TIII issue

As Paul Harvey used to say...And now the rest of the story

 

[sunwave]

I editted the entries per RRDB listing. Maybe @Butelsoftware can fix the DMR Tier 3 site import thing. Reprogramming my scanner. Will report what result is.

 

[Whiskey3JMC]

I've confirmed the same issue with Arc536 so the issue isn't exclusive only to ArcXT. OP's system indeed shows correctly in Proscan
Same applies to a TIII local to me so issue is not system-specific either


Update: I downloaded the latest version of Arc536 (2.7 Build 6 as of this posting) and the LCNs now display correctly. Admittingly I should have done this for my first test as I usually do. I never use it so I was quite a ways behind. @sunwave please ensure you're running the latest version & if that fails there's still Proscan

No update for ARC XT PRO, none at the time I posted this reply.

Manually reprogramming LCN's into the scanner itself worked. I tried it through Butel ARC XT Pro it would just re-enter 1,2,3,4,5. My changes did not stick when I tried editing the LCN's within the software. Only worked once I set the LCN's into the scanner itself.

RRDB listing is fine. Arc XT PRO needs fixing in that regard. DMR sounds good on this scanner.

+1 for Proscan
