Motorola GM300 cross band repeater

By Bryan Bibeau | Published January 9, 2015

I’ve been playing around with old Motorola commercial gear on the amateur bands, and decided to try a cross band repeater. This setup is using 1/each of the VHF and UHF versions. For ID and repeater control, I built an ID-O-Matic IV by hamgadgets.com. The duplexer is a MFJ916B. Antenna is a TRAM-1480 @ 35′ AGL.

    Hi,

    I’m very interested in doing this myself.

    How’s this project progressing? Did you need to modify either radio at all?

    Cheers
