Question for Moto Trunked Users

[katt02]

Hi all, This is a question directed towards people using Motorola radios to track a trunked system without affiliating.
Have any of you ever had your moto Bricked by the system for accidentally transmitting? If you have, would you mind posting a picture of what your screen said when this happened and the story behind what happened? I am curious as to what the powers are of shutting down Motorola radios that are not supposed to be on the system.

Thanks

The screen will show absolutely nothing, it will be blank. I've never had my radio(s) "bricked" (other than playing around), but I've inhibited plenty of them to now what happens.

It looks like it's off, no screen, no PTT, nothing. It will still respond to a Radio Check (ping) command from the Radio Control Manager, until the battery finally dies...

If you turn it off and on it will go through the MOTOTRBO screen then just shut off

If it is a TRBO radio sure but he didn't specify. XTS/XTL radios on Type 2 and Smartzone trunked systems once inhibited will not light the display screen. It will appear to be dead unless you watch the TX light and you may see one single blink when it comes up, system hears it and says NOPE. I don't remember what the Jedi series radios do and I've personally never seen a bricked APX.

Yea I figured I would put in my 2 cents since I don't own an APX and haven't bricked an XTS/L. TRBO radios can still be killed on trunking systems

Don't affiliate on a system that your not supposed to be on and you won't have a problem.
No I haven't had it happen to me, but as others have said, one blink of the red TX led and then nothing.

You will see this when you read the radio.

A radio does not have to be affiliated to a trunking system to be inhibited. I can send inhibit commands over conventional frequencies just as easily. I do it from time to time when radios that I loan out don't return to me.

I never knew this could be done via conventional frequencies, I'd imagine you need to know the radio ID and for it to be P25?

Yes just like on DMR.

Thanks for the screenshot rescue161 that is pretty cool and interesting. I wonder if it will accept a codeplug if it has been inhibited? I would imagine not but could you try that out?

Unless things have changed recently, Trbo radios have a setting in the CPS that prevents them from being inhibited on Type 2 analog trunking Systems. Specifically XPR6580’s.

 

[rescue161]

I send the commands in analog. It's an MDC data burst. The XPR6550 will not inhibit, but the 7550 will as well as the XTS line, APX, Jedi, etc. You can program it, but it won't make the radio work. It has to receive the uninhibit command to return to normal operation. Same with trunking.

 

[K2NEC]

The TRBO series radios can be programmed not to decode the disable command as well as the remote monitor command. I have that programmed on my 7550e for obvious reasons

 

[rescue161]

I set mine up so they will. It helps me recover radios when I loan them out.

That MDC stun can only be done via a console not from radio to radio and would need to be powered-on and within RF range?

It'd be scary to think some troll out there decoding ID's and stunning radios for fun.

 

[K2NEC]

One of the reasons I set my 7550e up to not decode is so someone can't mess with me and disable my $500 radio. Same with remote monitor. I would rather not have anyone be able to listen to anything I am saying at any time without me knowing.

 

[rescue161]

Yes, that is correct. I have a console here that can send out the commands. I use an SMT at work for the trunking system.

 

[K2NEC]

Do you loan your radios out for events or for public safety? If it's to someone that has never used a radio before it would make sense that they would try to pull a fast one and walk away with a portable

On the APX series you have the option of setting up the dummy KMF profile. I don't have a XTS/L series to try that option on.
