I have been searching the forums and google and haven't really found what I'm looking for so I will try here to address it as simply as I can.
I recently upgraded from an 396xt to a hp436bcd and got the dmr and nxdn upgrades, (don't ever pay the ridiculous price to have someone do it for you, it's way too easy). I use sentinel and proscan for programming and control. So here is my questions. In my area, (north west Minnesota) there are numerous dmr systems that have yet to be documented into the database. I now have a scanner that can do such a task however I am having great difficulty in programming and knowing how to program.

Using FCC Licenses I'm programming frequencies into my scanner using different systems and variations of different systems and have yet to have any real success. I realize that dmr tier 3 requires proper lcn ordering. One system that has grabbed my attention is a tier 3 system that has a control channel always broadcasting. It's a multi site system. Using custom searching in the range of the frequencies of the license I have found control channel, color code, and some of the frequencies used. yesterday while searching it seemed only one frequency was used all day (not the control channel however that was buzzing along all day). I am only 3 miles from the tower. I am confident that it is a tier 3 for many reasons. So, as simply as possible: under what kind of system would I program a dmr tier 3? TRBO? Do I program only license freqs or other ones that pop up in the search with same color code? Do I program the control channel only? Do I even program the control channel at all? I'm using LCN search feature on my 436 and It never completes its job. I save it and download it and examine them and i have differing lcns each time. It's not like I'm a beginner here, I've been doing this for 20 years. I'm curious and I'm sure that others are as well and looking for answers from a knowledgeable person who's not condescending. Thank you

PS, tips on other types of dmr systems would be helpful as well.

We do have several threads devoted to DMR programming linked in our FAQ for the SDS100 - but since the implementation of this mode is likely to be the same (or very close) to the 436, it's entirely relevant. See the 'Program a DMR System?' question of...


And I see the question of DMR programming is also mentioned here.....


Uniden has been downright reticent about releasing the proper procedures for programming DMR, MOTOTRBO (and NXDN programming, as an aside) for its various scanners. It's downright annoying. Folks have had to figure this out on their own without a lot of help from them. And don't get me started on their TWiki mess....

There are two ways to find DMR - scan the frequencies on the license or perform a frequency search. For the most part, frequencies with the same Color code are part of a trunking system/site. Sometimes not all the frequencies used are licensed, so you have to use both methods to find all frequencies. This is the case with Stones Mobile Radio. The control channel of all things is not licensed.

Once you have determined a good majority of the frequencies that are used, create a MotoTrbo system with a site. Make sure ID Search is turned on and run the LCN finder.

STONES MOBILE RADIO - Crookston
856.7375 - LCN 459
860.7875 - LCN 783
860.9625 - LCN 797

All other frequencies you find you will have determine yourself

Check post #11 for the formula

I'm here a lot
This is the blurb I put at the top of the DMR T3 systems that I add when I create a T3 system to enable listeners to monitor.


To monitor this system with your Uniden scanner, go to the CH ID list. You can find that listing by clicking on the Site Names.

A channel menu will appear. Subtract one (-1) from the channel ID and divide by two ( /2) This will give you the Uniden LCN.

Modify your programming with the new values and it will be monitorable with your Uniden product.


See if my method works for your programming.
