    Hello, I got hold of a used but in good shape Motorola GM 350 (Type MD334BB)


    This puppy has a LCD Screen and 11 push buttons on the front, a R.J 45 style mic jack, with the radio i also got mounting bracket and O.M.E Motorola hand Mic and mag mount base.

    my brother in the uk Bought it and sent it over to me as a gift as he knows i am into the ham radio hobby, Not knowing an awfull lot about this unit, i did a quick ggoggle search and found out that this radio (Depending on model?) can do V/UHF and 25 watts and have 128- Ch.

    But Furthe rading revrevils some small issues noted with ":confused: "

    from URL:

    Motorola GM 350 Standard Features

    Internal Loudspeaker with 4 W audio power

    Private Line (CTCSS) and Digital Private Line

    Programmable Time Out Timer and

    Re-Key Timer

    Single Tone Encode for repeater access or limited selective calling

    Single Tone Decode for limited selective calling (128 ch display models)

    Programmable Power 5-25 W, set per channel from 2 programmable levels

    Choice of 12.5 kHz or 20/25 kHz models :confused:

    Ultra-Wide frequency range for maximum system flexibility

    Plug in modules for enhanced functionality

    Data mode (128 ch display models) :confused:

    I am really looking for someone who knows more about the Motorola radios than i do :eek:

    thank you for any help.

    I'd bet the programming software will cost you more than the transceiver did.

    GM350 aren't all that versatile for use on the amateur bands. Part of the issue is the channel spacing, which you noted. And the fact there is only one sub tone, which is a real drawback when you travel. Personally, they're a relic.

    Motorola GM350 Info Request.

    how about a model number etc would that help?
    theres a sticker on the bottom of the radio that has the following:

    TYPE: MD334BB
    S/N: *****2039
    Model: M08KHF4AA3AN
    Tanapa: EUD4845B

    I tried to look the serial number up on that you can punch in the serial number and it spits out the Model Number Decoding,, but can only find
    GM 300 or M120 :confused:

    Any Help?

    OK just to give you guys an update, I dropped the radio of at my friends shop who deals with all sorts of 2-ways, we did a quick test on it and put it on the bench and tried veris of common rib/programs to try and pull data from the radio but non of them worked they all returned an error code or said the rib cable needs to be connected (it was plugged in), so this means back to square one...
    so let me ask the obvious, dose anyone have this program for programming the Motorolla GM350 or know someone that has it :confused:

    Thank you all
