In Hungary only PMR (446 MHZ) with max 500 mW is free for personal use. Building, buying, selling device which receives in any frequency is allowed, however owning or selling a device which transmits on other frequencies requires license. But it's not hard to get a hand on such devices - I have one, but I transmit only within the allowed range. If hell breaks loose, maybe I'll break the rules to call for help or help others.
My opinion is that by default Earl should keep the owner's country's rules by software barriers. Even, it should be possible to disable these features manually (like flight mode in mobile phones) and state in the manual that when going abroad where different rules apply it has to be done.
Yes, software barriers can be broken (evil hackers), but be honest, talking on the radio is public, no-one wants to fiddle with the authorities without proper license and knowledge. Earl has to be protected legally and any damages caused by misuse of the device is on the shoulders of the user. Same as a pocket knife.
