I noticed a posting somewhere with a somewhat confusing sentence that might allude that the makers of the board did not want to bother to have their radios certified by the FCC. I would submit that the makers should take a much less cavalier attitude about their products that transmit RF energy.
My statements only apply to the US regulations as I know that the EU is different. The 433 MHz board specifically falls withing the heavily used American 70cm band which is used by *both* radio amateurs and the military. The 433 Mhz *requires* an amateur radio license to operate in. This is not optional. It's easy to get, fun to do and well worthwhile.
The problem that exists is that when operating your 433 MHz radio you very well might interfere with either amateur radio operators or the military as there are specific areas that they need exclusive use.
Every time I post something like this It seems to be off-putting to a few people who think rules and laws are silly and somehow don't apply to them. But I promise you they do. For amateurs at least, you stand the very real chance of "klunking" or otherwise interfering with a repeater which is quite bothersome to many. We do, in fact track down offenders who interfere. We practice doing it and have contests around doing so. After that they will receive an official notification from the FCC which they are required to respond to by law. If they fail to do so, then the FCC will impose a federal fine. Fines are never 2 or 3 digits, start at 4, and usually are 5 digits for those people who want to ignore them. And of course, there will be all sorts of questions about the people who make the offending devices as well.
Besides that, ham/army transmissions *will* interfere with your device and you could spend a huge amount of time wondering what the heck is wrong with your glitchy equipment.
But it's real easy to avoid all that. Either be a ham radio operator (but you still can't interfere) or buy one of the other radios that don't fall within the 70cm band.
