Motorola DMR

[2EOJUX]

Sorry if this is in the wrong forum but it seems to be the only one that seems appropriate for the question.
Please ignore my ignorance but i dont know a great deal about DMR and hence, trying to learn.
Ive been listening into a a DMR station run on Motorola radios with both time slots and a few different call groups using both DSDplus and a Anytone at878uv plus DMR Radio. When using the DSDPLUS, i dont have a problem at all and can receive all data all of the time. However, when using the Anytone Using either digital monitor or with the correct TG and CC, within a few mins, the radio freezes and becomes completely unresponsive and this only happens on this one particular frequency.
Im aware that Motorola DMR gives the option to "stun" or "kill" a DMR radio and was wondering if they are using a repeater or something similar that can "see" any radio that is "listening" but is not registered on the system and "stun" it of "kill" it. ?
I know with Analogue, unless transmitting, its not possible to know whos listening but on DMR im not sure if the DMR radios send out some sort of auto registration packet or something similar as ive seen network registration processes for this frequency on DSDPLUS.
Can a DMR network "see" a remote DMR radio on the same talkgroup and colour code without it transmitting ?

Many thanks !

I might be wrong,

bur DMR teir 2 has not got such things.

it has RAS (restricted access to system) and radio block that prevents a radio from acting the repeater for any TX functions.

how even as long as your colour code matches the system and they are not using privacy , you will be able to receive even after your access is blocked.

T3 is very different and I think that’s where radio stuns come into play

Tier 2 has kill/wake capability. If the screen goes completely black and the radio is no longer functional it may have received a kill command, but turning the radio on/off wouldn't reset the kill command. You should check to make sure channel ranging isn't on and make sure roaming isn't on these would cause the radio to transmit if you have the repeater setup correctly in the radio. My guess is you just need to do an MCU reset or upgrade the firmware and then do an MCU reset.

Earlier generation of an Anytone HT, but should apply to your radio. Mine has always been off, but I don't listen to Public Service or Business frequencies so I don't know if it works if 'ON'.

P.S. CPS is 1.35, not 1.36

A radio monitoring, with out transmitting at all, can not be ‘seen’. As for the Anytone locking up, there are lots of reports of the Anytone doing this.
As for the Anytone not receiving activity, if the repeater is using RAS the. You are SOL except for a scanner or SDR/DSD+.

Thanks, that just about clears that up. However, I'm not quite sure what you mean about the anytone "not receiving activity" as I received all communications from all tg/cc etc until the radio died. I have seen issues with the radios but not the exact issue but what Confused me was that it only happened one particular frequency. It was a brand new radio with firmware up to date but I just wanted to make sure it wasn't something "their side" causing it. The radio has been sent back now anyway and I'm looking for something different. Thanks for your help.

Thanks to everyone for your advice. I now know that it's not something "their side" that's causing it and it's more likely just a faulty unit. I just wanted to double check as I'm new to DMR. However, the radio has gone back as faulty and I'm looking for something different.

If your radio was being inhibited, you could've seen the inhibits with DSD+.
