Program a Motorola GM300 via FTDI to RJ45 #hamradio #hamr #msdos #vmware

The Motorola GM300 was a robust radio in its heyday, part of the Radius family of devices that was also compatible with MaxTrac accessories. It has long-since been discontinued but continues to be sought after and coveted by collectors and operating hams alike. Edouard Lafargue from aerodynes.fr is one such operator and wrote some interesting pointers on programming the GM300, via this clever FTDI to RJ45 circuit:

The main issue when receiving one of these old radios, is that the only way to program them is to connect through their RJ45 microphone plug in front, and run a DOS utility that was last updated in 1995.
