VOX when the radio doesn't have VOX originally built in - by making a "squelch-controlled VOX" system. I have a Midland Regatta I VHF marine mobile radio with a squelch knob on it. I wanted to do a little work on this radio to try to make it use VOX so it could be connected to a scanner (receiver) and basically used as a repeater. I have no idea where to begin with this project. Anything helps! Thanks in advance! -Dave.
