That was exactly my thought but they are only counting "registered/licensed" C-band downlinks. As we all know, there are many more un-registered professional downlinks than those that have paid the $395 registration fee. I reaimed a bunch of dishes to AMC18 this summer and not a single one was "registered" nor was required to be.
I have emailed Chairman Pia and Commissioner O'Reilly with my concerns and a request to waive the registration fee for licensed AM, FM and TV stations as well as cable headends.
This is something that we need to keep an eye on as the FCC tries to auction off access to every frequency possible. The wireless companies are big bucks lobbies that can magically bend the rules of physics.
