I use Kenwood FRS radios with the Autocom system. The range is only about a mile or less but that is usually enough to keep in touch except on a large, spread out group ride. Otherwise, nothing but static free com with very, very little interference from other users. We're on the move so if we hear someone else, it's usually only for a couple of minutes and we're out of range, again.
I tried some higher powered radios but I had negative results. The small low powered units work just fine and the speech is clear. No potty mouth like on the CB radio. These radios certainly make the ride more enjoyable when you can share sights and thoughts as you travel. I always look forward to riding with my other friends who do have the com system so that we can communicate as we ride.
