SDS100/SDS200: dmr tier 3 question

[lild83]

i am hoping someone can please help me out on how to program a dmr tier 3...i am using an sds100 scanner and did the custom search i came across a frequency here in my town of lubbock texas the frequency is 463.3500, i did look up the frequency and it shows it being on 2 different call signs..
i recognized the traffic being transmitted as this company used to be on a different system... it keeps popping up dmrt3 and cap+ ive programmed it as a single site conventional and feel as if i miss traffic, i do hear some kind of computer audio like the data channel i suppose while on conventional . i have even programmed it as a dmr one frequency and mototrbo and when i do the dmr one frequency it still shows dmrt3 cap+ but no audio traffic or even talkgroup pop up..... ..... just fyi the mototrbo doesnt do anything any ideas how to program this or find out anything else about this frequency???

First question I have is: Does that SDS 100 have the DMR key added to it? It is a separate purchase but if you don't have it, you won't be able to listen to any DMR traffic.

I do have the dmr key added to it

Can you provide a link to the database page that includes this system?

Or, if the system, itself, is not entered in the database, how about the location? City, or County, and state, plus the name of the system or the licensee would help us get you an answer.

Its not on the database the city is lubbock texas
And the frequency is 463.3500 but shows up on wpes697 and wpkn948 and on the first call sign it shows up as a dmrt3 cap+ and the other call sign doesn't show up anything on my scanner

For license WPES697, frequency 463.3500 is the only frequency on that license. It is not licensed to use DMR, but often licensees may use a mode they are not licensed for. From other similar instances, apparently the FCC may not pursue that as long as they do have a valid license for the frequency, even though that are not specifically licensed for the mode in use.

For the other license, WPKN948, frequency 463.3500, and four other frequencies, are licensed for two separate locations in Lubbock County.
Here's the frequencies, licensed for each of those locations"

Here again, while there are five frequencies on the license, no DMR emission types are licensed. But again, they could be using DMR, even though not specifically licensed for it, but the license is for a trunked system,

Programming it as a digital, conventional, frequency, you're not going to see talkgroups, even if they are using a DMR system. I would program each of those frequencies into a One Frequency Trunked system (OFT). If you have software such as ProScan, you can look at the logs of transmissions received. If you see the same color code, and the same TGID, show up on more than one frequency, then that confirms they are using them as a trunked system. You could then program those frequencies into a DMR trunked system for your SDS100, and use the LCN finder function to help identify how it's set up. Once you can verify the color code used, as well as the frequency channels with their correct LCN #s, then you can go ahead & set it up as a DMR trunked system. (Be sure to run the DMR OFT system in ID Search mode.

If you don't have software that can log transmissions, you can set the scanner to record all activity. Then, use the Universal Scanner Audio Player to assist in verifying usage by reviewing the audio files. (The download link for that is at the bottom of the linked post.)

I've tried already to do a dmr one frequency for the 463.3500 frequency it will will flash at the top right saying dmrt3 and cap+ but no sort of audio or even a talk group and id search is turned on

I would go ahead and add the other four frequencies on the license to the OFT and she what you get. The 460.3500 might just be only carrying data, not voice traffic.

I hear voice traffic on that frequency if it's programmed as a conventional channel, and while it's in conventional mode it it flashes the dmrt3 and cap+...so I programmed it as OFT and mototrbo and no audio or talk group in I.D. SEARCH only that flash of the dmrt3 and cap+ with a slot number

The firmware code code can have been written in a strange way so that if you do not have any TG programmed it will skip the ID search function and never detect any TG's. Always set a dummy TG 1 to any programming you do.

OFT should work to get audio from any DMR system type as long as you have the frequency correct and have set Color Code Search.

Hi ubbe, just tested again yesterday, programmed as oft, cap+ with ras not working… even with id search, cc search, dummy tg1

Does it decode the data signal? Do Channel+frequency+Channel and it will receive in analog and if it can decode the data stream it will switch to digital. In digital mode it should display color code for the control channel frequency and for voice channels it should display the TG and have voice, if it isn't encrypted. Have the display set so it displays the D-error value.

Hi, it shows cap but do not open voice. I will try program it as conventional, just to see what happens.

 

[Ubbe]

Are you sure that the system are in use? I have several systems that after the Covid close down have no users but CAP+ systems are still on air.

It has it, if i program it as trunked mototrbo, it's working - also on dsd . I think it has something to do, that it's single capacity + frequency and this might be an issue...

 

[vselic]

Conventional is a no go, it sits on a channel forever, due to the bursts.
