325p2 Firmware LCN Finder

[Chris0516]

Would it be possible for Uniden to create a firmware update, that would create an LCN Finder on the 325p2? I know that is a gargantuan request, just curious.

 

[enosjones]

I'd doubt it, not much updates on anything since upman died

That is sad. My only reason for asking, is because. Finding the LCN's is not as easy as setting up a P25 system.

 

[enosjones]

Yeah nxdn and for tier 3 kinda require the lcn's to follow or to track it properly, dsdplus gives LCN info or the more expensive scanners bcd435/536hp sds100/200 do lcn finder

I d/l'ded DSD+ and AIRSPY. Before I bought the 325p2, I had actually debated getting the 436HP. But, I chose the 325p2. Because of its' design in a standing position. The 325p2 is 'short and stocky'. While the 436HP is 'tall and thin'. Which makes it so easy to knock over. That you could just blow on it, and it would fall over. If the 436HP been 'tall and stocky', I would have bought that one instead.

I have the sds100 and it has the "sort-of tall and skinny" take to it and the only way it falls is if I fat hand hit it or bump my table. You can do what I recently started to do was use a coffee mug and put it inside it lol.

That's not likely.

Back when the NXDN upgrade was released for the 325P2 & 996P2, UPMan had said that originally, he did not think it was possible to offer that option. That was because of the limited amount of memory available to use. But, obviously, they managed to find a way to get it done. Trying to add an LCN Finder option would require the use of more of the memory, which was already noted as not much headroom available. The unknown factor is whether the components in the 325 & 996 are capable of doing an LCN search, even if the memory was not a factor.

In the past, most Uniden scanners did not have an LCN finder option. The first semi-recent model that did, I believe, was the HP series, if you added the Extreme Upgrade.

Thank you for the informational explanation.

I think they might be able to do a kind of work around.
The 325/996P2 have CC only settings in search mode. If I go to a CON+ system I can watch the talkgroups and RIDs.
If that feature could be changed to allow ANY streamed information to be displayed, the channels might be found that way.
With the logging in scanner software, you don't need to have the scanner auto program itself, simply output the info to text or display

It was said by UPMan that the 325P2 and the 996P2 did not have much room left in the flash memory so without a hardware change any large change in the firmware of these 2.

Does that mean I can stop gathering data for updates?

Seriously, I am not sure the 325 has the horsepower left to add that.

 

[enosjones]

I meant firmware updates on any of the newer scanners including the 325, not much has happened since he died, I'm sure stuff is going on, but just not seen anything, and the pandemic hasn't helped, now Texas being snowed in.. Alot going on the last while

 

[JoeBearcat]

A new model was released last summer. In the past month: BC_VUP was updated for the BC125AT and other models. There are updates coming for the other current models. The TWIKI is being updated (on hold due to the power issue). Lists of issues (hardware issues, software issues, bugs, and feature requests) are being compiled. There is a whole thread devoted to that.

 

[enosjones]

Ok I wasn't aware, things just seem quiet , up man kept us updated, so with the pandemic and everything, it just seems quiet I guess, sorry I know u guys work hard, just seems such a blow to lose upman figured it would take a while to get things going again

 

[buddrousa]

Joe has been posting less than a month in his new position and is trying hard to get things better.

 

[enosjones]

Ok that explains that then yeah, it’s hard to replace people, some people are one of a kind. I’m glad we have someone

I think I found an answer in an RR thread from 2013: https://forums.radioreference.com/threads/where-how-to-find-lcn.268743/

Referencing the Honolulu County Public Safety System
at- Honolulu County Public Safety System Trunking System, Various, Hawaii - Scanner Frequencies

The first respondent in the thread said:

"Pick the site that gives you the strongest signal for the EDACS control channel listed in red.

When prompted for LCN enter the 85X.000 freq to the right of those tiny greyed out numbers.

Enter those grey LCN as listed and not randomly."

So, That takes out the 'ugh', about not having the LCN Finder in the 325p2. Since EDACS is ProVoice(I don't have that upgrade). Doesn't the same thing apply to DMR n' NXDN?

Not exactly the same issue.
By far, most EDACS systems have been in the database for quite some time, and along the way the systems have been documented and confirmed LCN’s entered into the database.

On the other hand, it’s only been in recent years that scanners capable of monitoring NXDN & DMR trunked systems have become available. (I know that certain other receivers, particular those for amateur radio usage, can decode DMR or NXDN, but they do not track the systems.) Software for use with an SDR dongle has also become more capable and available as well. As more members acquire the capability to monitor DMR and NXDN, more systems are being found. especially among business users that are in the database listing a now decommissioned LTR system that was converted to DMR. We are also seeing selected public safety agencies use DMR (or NXDN) as a way to convert to digital more cheaply than with P25 trunked systems. Undoubtedly, there are more DMR & NXDN systems in use, especially for businesses, that have not been discovered & documented as far as determining the correct LCN usage.

While the Whistler database scanners that can monitor DMR do not need the correct LCNs to be entered to work, they also don't actually track the system. Instead, they focus on which talkgroups are being used. The Uniden scanners, with the paid upgrades, can track the system correctly, but that also means that the LCNs must be determined & entered correctly. Unless you get really lucky, and have a DMR system where the LCNs were assigned based on the order of the frequencies, with no gaps, the Uniden scanners will not track the system & you may miss calls.

I have the DMR n' NXDN upgrades from Uniden.

 

[hiegtx]

I have the DMR n' NXDN upgrades from Uniden.

As do I, including for my 325P2. But that still does not add an LCN finder function to the 325. Without the correct LCNs, the 325P2 will not correctly track the system. You can enter the frequencies as conventional, and try to monitor that way, or add each of the frequencies, as individual 'sites' into an OFT DMR system, which would let you use TGIDs for specific functions, but that still is not actually tracking a system.
