How do you program a DMR system? DMR TIER 3? NXDN?

[PanJurekMrJerry]

Do you need to program a DMR system with all the frequencies or just the Control frquencies
ALSO can a Whistler TRX 1 scan a TIER system or not? What is the difference between NXDN (C) and NXDN (D)?
Thanks for your answers.

A TRX-x scans voice channels on DMR trunking. The rest of your post does not have enough info to answer.

What is the difference between NXDN (C) and NXDN (D)?

See this thread...

NXDN(C) and NXDN(D)

On the EZ Scan software theres that option,can someone explain the options?

The scanner is a Whistler TRX-1.

 

[buddrousa]

To program DMR or NXDN Trunking enter all frequencies the set a wildcard or all your talkgroups.

 

[PanJurekMrJerry]

So because a scanner scans the Voice frequencies, does that mean that we do not have enter the other frequencies? We just need to enter the Control frequency, right?

 

[buddrousa]

NO WHISTLERS do not TRUNK TRACK you must enter all frequencies for DMR and NXDN.

 

[PanJurekMrJerry]

Do the Unidens trunk track DMR and NXDN? I know that the TRX-1 will work with only Control frequencies on P25.

Do the Unidens trunk track DMR and NXDN?

Yes DMR & NXDN trunk track works on uniden.

NO WHISTLERS do not TRUNK TRACK you must enter all frequencies for DMR and NXDN.

Does that mean the TRX 1 won't trunk track a Motorola 800 system? I only entered the control freq.

 

[buddrousa]

It will trunk track P25 Trunking and Analog Trunking. This has been posted here for years and the information came from Don Starr GRE/WHISTLER spokes person.

 

[PanJurekMrJerry]

Okay. So we need to enter all the frequencies for DMR just like we do with EDACS and LTR. Right?

 

[buddrousa]

Yes just like a LTR system and it should work good for you as long as it is not a very busy system.
My TRX's are used until I can break the systems and get LCN's then my Unidens go to work.

 

[PanJurekMrJerry]

Okay. Thank you. I am starting to get it. Do they have to be in the order that they appear in the RR Database, just like EDACS and LTR, or does it matter? Also what is the difference between the different Tiers of DMR and why does it state that the TRX-1 will track/decode Tier I and II? Will it not work on TIER III?

 

[buddrousa]

The scanner may like it better if you enter then low to high per favorite list.

 

[PanJurekMrJerry]

Thanks Buddrousa. So what does the Color Code have to do with DMR? Does NXDN have something like this too?

 

[cg]

I believe Uniden has at least some of the Tier III systems able to use the control channel only form of scanning the system. The problem then isn't how to monitor a system where you know the current control channel but how to know ALL of the control channels.
These are scanner that can be reprogrammed over and over with computers. Give it a try with basic info programmed and if it works, go and program in the rest of the info.

Thanks Buddrousa. So what does the Color Code have to do with DMR? Does NXDN have something like this too?

Simple answer to that is color code is similar to a PL and a NXDN system uses a RAN code. In the scanner programming these can be set to wildcards so you hear/decode whatever it is
