GMRS Radio Range

Just how far can you talk on a typical GMRS radio? Well, for starters, there is really no typical GMRS Radio, per se. If you see a GMRS radio bubble pack of walkie-talkies claiming "10 miles" as range, it probably is a 1 watt (or even less) radio. The good folks at Motorola put together a nice little video that explains it fairly well.
