They most certainly do license transmitters. It's only in the Ham type services the operators are licensed and can put transmitters anywhere (almost). That's why the commercial licenses have coordinates and frequencies on them.
As for the rule, I know it exists, but I don't know exactly where offhand. I think it's going to be in the 'lower CFR parts', not in the rules specific to any one service. On the other hand, all the tower signs I've ever seen don't reference any specific rule - they just talk about the site being under the "jurisdiction of the federal government". Nobody I know of quotes a specific law. Joe M. Gary wrote: > > Not sure what you mean John.
