that's right, I don't know what I was thinking before now if only the
equipment was inter changeable between companies it would be better since
with racing going to serius in a couple years, I'll have to now get a serius
radio too though I'll keep XM for the better music and old time radio shows.

It appears that the March 9, 2001 order of the FCC which ammended Sirius's
application to operate three instead of two eliptical orbiting satellites.
The frequency range is 2320-2332.5MHz, which is similar to XM Radio, as the
FCC has required in both orders that satellite receivers have
inter-operability.  They do also have authorization for earth-to-space
tracking and telemetry at the 6425MHz band; and I think Space-to-Earth in
the 4.2GHz band.



Here are the first couple sections of their order:





1. With this Order, we grant the application of Sirius Satellite Radio Inc.
("Sirius"; formerly Satellite CD Radio, Inc.) to modify its space station
authorization. Sirius holds a license to construct, launch, and operate a
satellite system that will provide satellite digital audio radio service
(hereinafter "satellite DARS" or "SDARS") in the 2320-2332.5 MHz frequency
band. The proposed modification will allow Sirius to use a three-satellite,
non-geostationary orbit ("NGSO") system that promises to offer better
quality satellite DARS than its originally authorized two-satellite
geostationary satellite system.



Background

2. In October 1997, Sirius was authorized to construct, launch, and operate
two geostationary satellites located at 80° and 110° West Longitude to
provide satellite DARS. Satellite DARS is a "radiocommunication service in
which audio programming is digitally transmitted by one or more space
stations directly to fixed, mobile, and/or portable stations and which may
involve complementary repeating terrestrial transmitters, telemetry,
tracking and control facilities." Beginning in mid-2001, Sirius will operate
a satellite system providing coverage to the contiguous 48 United States
("CONUS"). It proposes to offer these services as a private satellite
operator, providing neither common carrier nor broadcast service. By this
application to modify its authorization, Sirius proposes enhancements to its
planned satellite system that it asserts will better fulfill the potential
of satellite DARS, and thus serve the public interest, without raising
additional technical or potential interference issues.
