I'll never understand why the FCC has some its silly equipment rules. Hmmmmmm..... Maybe the Government should also limit the amount of horsepower a car can have and where and when we can drive it. The government seems to forget that they make operating rules and we have to follow them. They don't need equipment rules at all. If we break an operating rule, we pay the price. I think they are just too lazy to get off their ass and enforce the operating rules. It is still completely legal to build your own radio that can do whatever you want it to do. You just have to obey the operating rules when you use it.
