Programming DMR With MOTOTRBO Cps 2.0

[Jack_speight]

Hello, I am trying to program my XRP 7550 as a receive only unit. Its a DMR conventional system im trying to program in. Where does the frequency go and the TG? Anything else I need?

Per The database listing RAS (restricted access system) is being used which means you will not be able to monitor with a motorola radio unless you know the RAS key.

Hmm ok, my Bearcat can pick it up so thats strange. Anything you can think that would change this?

Scanners ignore the RAS packets. Most radios do not. If they actually are using RAS, nothing will change that on the radio unless you have the RAS key.

I understand, the FD and EMS most likely don't have it enabled.
thanks

RAS is a motorola proprietary feature, other radio manufactures are still able to decode the voice as long as the voice isn't encrypted.

That would be a very long involved answer if you do not know how to use the software. Do you actually have CPS 2.0 running on a computer? If you do know how then create a new contact (group call) for Dispatch and Tac, a RX Group list for each group call, and when you create your channels there is a box you can check for RX Only.
Beyond that you can create scan lists or even roam lists. If you don’t know software and don’t plan on doing any or much programming then download whatever is in your radio and get someone to edit it for you. It would be 4 channels, 2 per site so easy to do.
I think conventional RAS only prevents you from bringing up the repeater when transmitting to it with wrong radio ID (handshaking), which you will not be doing and has nothing to do with receiving from the repeater.

Nope. As I and others have already mentioned, Mototrbo (and most other radios) will not unmute with RAS unless you have the RAS key. Some radios and all scanners (to my knowledge) ignore the RAS.

Without getting into the nitty gritty of RAS, there's two different types. ID range check and Key Authentication. Vernon applies Key authentication which means any 7550 regardless of the radio ID will not be able to receive (or transmit) on the system without a valid RAS key. Easiest way around it is to get a DMR scanner

Not true, neither cheap DMR radios nor expensive commercial grade will decode

you don't have a clue. I know a radio station, that will decode ras and is not motorola

Oh and what "radio station" is that? 96 Rock? 99X? B98.5? Tool.

Sorry, english is not my mother language, so I messed it. Anyways, i will never tell you the answer, especially because of your altitude! The radio simply ignores crc checksum, so if traffic is not encrypted, only ras function ON, it will ignore it and decode the dmr traffic with no problem.

Scanner does the same thing. Thanks for playing, have a great day.

BTW, Anytone has a version that will decode RAS transmissions. So if that's what you're talking about, I already know

Wow that's an awesome way to help the community.

I've tried the most recent version that includes ARC4, and it definitely doesn't work with RAS... Unless this is a hacked version or something you are referring to.

Folks, the snarky attitudes aren't helpful. Keep it up and I'll close the thread.

I'll shoot you a PM so we don't completely derail this thread
