The WeatherDuino can use radio modules operating in the 433Mhz or the 315Mhz frequency, without any modification in the software or hardware. Performance is almost identical. So, using 433Mhz or 315Mhz its a user choice, considering local regulations.
In Europe the use of 433Mhz radio in devices like WeatherDuino is perfectly legal. Indeed, almost all radio weather station, alarms etc, operate in 433Mhz (some in 866Mhz).
If there are any issue using 433Mhz in the USA, users can opt for the 315Mhz radios
