I'm no expert, but I gather each government sets aside certain frequencies for no-charge personal radio use. All other frequencies have to be paid for, or granted free-of-charge. The unfortunate thing is that the US and UK use different formats/frequencies - FRS in the US, PMR446 in the EU. If you do a search on the web, you'll see that it is very much illegal to use a PMR446 radio in FRS territory and vice-versa. I would have thought that physically getting caught red-handed would be unlikely, particularly given the short range of these radios, but I don't think I'd trust the US authorities to see the funny side over the use of illegal communications equipment in the Homeland. Mind you, given that cheap FRS radios are apparently high on the list of Brit buys, maybe one of them will give us their own views, under the cover of anonymity, of course.
