Back in the 70's I breadboarded a VOX circuit that used a diode voltage doubler driving a big cap and a NPN transistor keying a small reed relay. I put a "ouncer" telephone transformer in line, and a .01 cap and pot in series for the repeat audio path. I mounted it all in a little project box I had, two terminal strips for I/O. Plug the input into the speaker jack on a rx radio, and mic and PTT into the tx radio and off you go. Users had to voice ID it as they ID'ed. Ran that at a couple of hamfests years back, rx was an Icom IC-22A or 22S, tx was a KDK FM144 on 1W. Toss it under the seat, gain antenna on the roof for rx, rubber duck or 1/4-wave mag mt under the car (or in the trunk)for tx. Sounded like crap, but it worked. -- Jim Barbour WD8CHL
