I know a lot of people hate the licensing process and think there should not be any, but the FCC keeps big business and people with more money than Joe Q. User from bullying their way into radio spectrum that individual private users access. The only way the FCC can track exactly how popular the bands are and how many users are actually using it, is via the licensing process. If there isn't enough traceable activity, the FCC will sell the space to commercial users and we will lose our allocations.
I only mention this because, I think if we run into people that are unlicensed in a services that they should have one, we should explain this situation to them in encourage them to spend the little bit of effort and funds so we can all continue to enjoy the services over the coming years.
One is a CCR, the other is an ECR. LOL
