Need help removing trunk settings - MTX8250

[gjohn14]

I recently purchased an MTX8250 from a Motorola radio dealer in my local town..
I went online and purchased:

Motorola Trunking Professional Radio CPS - R02.03.00

I can read the radio fine I can program and write all of the conventional side of things fine..

However, when I viewed the trunked side of things I noticed it was fully programmed to connect to a trunked system with ID's and all!

When I tried to remove/reprogram the trunked settings to a null value or any value for that matter CPS would not allow me to make any changes.. In fact most of them are greyed out..

I immediately called the dealer I purchased it from and politely relayed my story.. I asked if they could just remove the trunking info already programmed into the radio.. To my astonishment they said no.. We don't do trunk programming of any kind..

I just want to use this as a conventional radio.. I want no trunking of any sort!

Can someone enlighten me on how to remove the trunking info??

I don't want this thing trying to connect to any trunked system = NOT GOOD!

Thanks in advance for any help gentleman!

In order to add, change or remove any trunking parameters you need
a cps programing key. Without it those fields will remain greyed out
and not allow you access. The key is obtained from motorola when a
trunk system is purchased from motorola. But in order to only remove
trunking parameters any key(from any moto trunk system) should work.

The trick for you will be finding one as most trunk system admins do not
give them out for security reasons.

I think there may be key generators somewhere online but I have no info on
that. If you find one it may help you out with your problem.

Good luck...

it has to have 1 trunk system in the CPS, even if it is an invalid one. as long as you do not have one of the talkgroups assigned to a channel slot in a zone, then your radio is ignoring that TG and that system.

first double check your scan list and make sure they are set to conventional. next you can delete any channels in any zone that show as trunked. then delete all but 1 trunked personality then delete all but 1 trunked system. the delete button is at the bottom of each personality/system window. program and you are good to go as a conventional only unit. i just verified this information on one of my archives, you cannot take all trunk systems/personalities out but if they are not in the Z/C list they are not usable and are ignored.

Sorry dave - thats not true anymore. That does hold true with some of the older rss trunk
radios such as a maxtrac but with the newer cps software you can remove the last trunk
system personality and replace it with a default trunk system personality which is the same
way the radio comes new with default programing.

not without a system key loaded, i JUST did it. it will let you delete all but 1 whether you have keys or not.

edit: scratch that, we are saying the same thing. it has to have 1 trunked system even if it is just the default. you add in the default trunk system(which if your current system shows 0001 it is the default) then add another trunk pers and assign it to the default system, then delete the trunk pers for the original, then delete the trunk sys for the original. but like i said, if it ain't out in the Z/C list it ain't usable anyway and the radio will never switch to the system even if it is a valid one. most likely he is seeing the default system though.
