[arm-allstar] Channel Steering on Motorola RIM-Lite

[Mike - W5JR]

FYI, the video clearly states using GM300 radios, not Maxtracs. However, his method is not using the binary steering lines of the accessory connector, so there is some compatibility with a Maxtrac radio, possibly even a 2 channel version, for his clever scheme. I don’t think one can change the displayed channel number, and thus may be limited to 11 channels without some additional circuitry. 

Still clever. And likely applicable to other manufacturer’s radios. 


tnx
