Batboard

Hi,

I recently purchased a motorola mobile gtx model: M11WGD4CB1AN
off of EBay. When i received it i was able to check it on my bench.

It transmitted at 896.1625 Mhz. Was not able to check its output level.
Since i did not have the necessary additional equipment and experience
i choose to send it to a local motorola repair shop that said they could
do it.

So after a few days they call me and state that their equipment tells
them the frequencies i requested 927 mhz receiving range is out
of the range that the radio will take.

They said the equipment gives them error reports stating this is out
of the 896 to 902 and 936to some other frequency i don't remember.

So they will send it back to me. What is the problem?

Thanks,Jim.

They would need to modify the database file in the GTX programming software to expand the range to cover 902-927, rather than the 896-902 and 935-941 MHz range that is used on the commercial equipment. Whether or not they'd be willing to do it is up to them. The procedure to modify the file can be found in the MaxTrac-specific section of BatLabs.

An alternative is to find someone locally (a ham) who already has the modified version and will program things for you. If that fails, there are several of us here on the BBS (myself included) who can, and will, do it for you for the cost of shipping.

These radios easily cover the amateur band for 25 MHz splits, i.e. transmit around 902 and receive around 927, as well as transmit around 927. As I posted earlier, the receivers seem to be good from about 913 to at least 941, which is the normal programming limit. I bet they'll actually go higher if the limits in the software were changed. As the local repeater here in CT is a 25 MHz split, I haven't had the need to experiment with the 12 MHz split frequencies, whatever they are.
