Motorola mtx-900s

[l3pr3chaun]

I recently acquired 10 mtx-900s units and only two of them have the capability to talk radio to radio. The rest of the units will have the transmit light flash on a few of the channels, but only once in a great while willI each of them communincate with another radio.

Almost every time the talk button is pressed I get that BAAHHHH sound followed by static. I know that these units were working previously.

The history of the radios is that they were on a radio to radio link with repeaters and also could be used on the trunked system that was installed.

I know that the baahhhh sound is an illegal operation, but im looking for some guidance on how to get the units working properly. Any suggetions or checks that need to be performed on the units?

Have they been properly programmed?

I have not checked yet to verify that they are programmed correctly, but I don know that almost all of them were still being used before I received them.

Would you recommend that I order the program cable and start looking at that being the issue? I am not familiar with these units at all and will need to locate some other documentation before I go hooking up the units to try and program them..

By "programmed properly", I mean, those radios are going to be operated in a licensed service, be it a commercial service, or amateur service. As such, they need to be programmed in a specific manner consistent with the service that your license to operate conveys. If they're just random radios you picked up and expect them to work like FRS or CB radios, that would be an incorrect assumption. They are likely trunked radios, which requires affiliation with a trunked repeater system.

Based on what little information you've provided, one could assume that you haven't obtained a license of any sort, nor paid for any trunked repeater service, and the radios have whatever programming the previous user had. That would generally mean that it would not be legal, or advisable, for you to use them. I would specifically recommend that you avoid attempting to program them unless you know exactly what you're doing.
