  • Programming GM900

    From Bo-Lennart Karlsson@21:1/5 to All on Tue Jul 18 05:13:53 2023
    Hi, all out there.I need some help to programming a MOTOROLA GM900-two-way radio. The radio cover the UHF-band of 403-470Mc I understand that the programming should be done through the mic-connector (RJ45) of the GM900.I need a schematic of that cable
    between the station and the computer, and the software to make it done. Anyone? I would be very happy if someone would like to help me.

    With the very best regards from SWEDEN
