The &quot;23 mile range&quot; business is very optimistic. You&#x27;ll probably never see over 5 miles of range unless it&#x27;s line-of-sight between two mountains. However, they&#x27;d be great at most festivals or e.g. Burning Man. Look for something FRS or GMRS. There are also 2-meter (~144mhz) radios which parent is talking about like e.g. a Baaofeng UV-5R which are inexpensive software-defined radios that can operate on licensed and unlicensed bands. If you get something like that, you should be aware of the power restrictions of FRS and GMRS and the licensing requirements for GMRS.<p>TL;DR unless you intend to get pretty into it and just want something for festivals and something to give to non-radio-geek friends to use, just get a FRS or GMRS radio. Motorola and Uniden both make quality sets that will work up to a few miles away at festivals.
