Thats 700,000,000 not 700,000, and there is no comparison, free radio is everywhere, and does its job of reaching the public.No pay service will ever match that coverage. The government would be foolish to try to depend upon pay subscription radio exclusively to get its message out to the most people. However, there are times when sat radio does serve a need, as in New Orleans during Katrina, many local radio stations went down, and XM and Sirius were both used by the public- I know first hand of this situation. Batteries and a XM or Sirius radio kept people in the know when even local radio was off the air for awhile. Both terrestrial and sat radio can and should perform public service hand in hand, its not competition when it comes to emergencies. Oh by the way I have had XM and Sirius for 5 years, and have had reception without repeaters from Veracruz, Mexico up to Anchorage, Alaska. I get indoor reception, with no repeater signal where I live and in several other locals around the USA ( central Washington, southern Utah, Northern Minnesota, northern California, and Yukon, Canada, none of which have repeaters within 150 miles). Reception problems vary, often more problems in urban areas due to local interference and obstructions. Repeater range is actually limited compared to regular radio. (Oh yeah, a vehicle is a great place to get radio recepetion during emergencies, when the power in the home is out).
