While it is lightweight it is yet another item to bring along with the radio. I decided to modify the charger cradle to support USB input instead. I drilled a hole to mount a spare USB cable I had around and and fixed it with some hot glue. To safeguard the USB port I installed a 1A fuse in series with the 5V (red) wire of the USB cable. text/html 2016-12-19T14:25:45+00:00 Anonymous (anonymous@undisclosed.example.com) https://kjen.dk/web/radio/motorola_gm-360_emergency_repeater?rev=1482157545&do=diff If you want to build a simple repeater using two Motorola GM-360 radios, you might want to have a look at this presentation I gave at a Red Cross IT & Telecom Emergency Response Unit Training in Washington 2010: Building an Emergency Repeater Using Motorola GM-360 radios
