Another option is to use aviation intercoms which are already set up to use 24 volts. They have radio interfaces that may be able to be adapted to CB or FRS radios and many have audio inputs for entertainment radios. This way you could use aviaton headsets with built in microphones for communication.
They are generally voice activated and for the extra noisy cabs can be made switch activated. If you want to go all out there are several noise cancelling type headsets on the market which make communications and long rides even easier.
I have been planning to build up one of these in a 50cal ammo can to sit on the floor of my deuce so that it looks like it belongs.

Greg

In convoys, our normal radio channel is 10-10 if I'm not mistaken. It's great to pull up next to another member while on route and call him up so to speak. For convoys it's a very valuable tool, call to stop for gas, or a pit stop, rest, etc. While there are a great deal of FRS radios out there, only the Motorola and Kenwood standout as the best of those radios. A newer design, GRMS, uses many of the same channels, has a better range (5 miles instead of 2.5), and more features.
