Are Sirius and XM Radio really terrestrial broadcasters?

摘要

Those poor folks at Sirius and XM Radio. They just get finished with one FCC scandal-overpowered FM modulators that violate FCC Rules-when they have to disclose that their networks of terrestrial repeaters have been operating illegally. As it turns out, those violations are no big deal. But as I began to investigate this latest controversy, it suddenly hit me. They aren't really satellite broadcasters with terrestrial repeaters to fill in the coverage gaps. What they really are is terrestrial broadcasters with satellites to fill in the coverage gaps.
