uncompressed digital audio over a given channel, but why would you want to?
BUT, I'm sorry, I can't let your off the cuff analysis of FM go unchallenged...
The simple analysis you did only applies to AM radio. FM radio bandwidth is another beast...
Back in the old days, some guys at the FCC made this mistake you just did. FM radio is a funny
thing, w/o going into much detail, you can trade bandwidth for S/N in FM (unlike AM).
With FM (or any phase modulation scheme), the more SNR you have, the smaller the FM frequency
deviation you can use and still transmit the same info. Since the frequency deviation is smaller
it will (following Carson's rule) also occupy a smaller bandwidth.
So the 44kHz -> 88kHz BW analysis is sorta bogus for FM, it depends on the moduation scheme.
FM radio was designed to work in low SNR environments so it has pretty wide BW.
But if you had 1000:1 SNR, you could redesign it to take up lot less bandwidth

Then Again... (Score:1)
A slightly different idea is being pushed by the US's FCC. Recently they changed certain rules to make opening a small radio station inexpensive. For around $5000 a person can obtain a license and the equipment to start a small radio station with the broadcast range of about a mid sized town. Sure, this is not nation wide, but it is going to be a great way for different kinds of content to get on the airways. This is very good for those who love both radio and non-top-40 stuff. If these things spring up around the nation, you could even get networks together, like BBS's in Fidonet. Then you could find the same show, anywhere in the country, if the town has a local radio station in the group.

One of the nice features about L-band though is that the there is a data stream separate from the audio stream that can transmit information like the name of the song, current weather, etc.
Before you go out and get an satellite radio receiver, remember this, if an L-band source get's knocked out then it only costs a couple thousand to replace (and there are tons of them spread around), mean while if a satellite gets knocked out, then its a couple hundred million to replace (these will have to be geo-synchronous satellites, not LEO,)..

Re:Variety? (Score:1)
These satelite radio businesses, however, seem to be set up so that all the channels on the service are owned by the same company, so they aren't competing with each other. Instead, the service as a whole competes with a different service, and whoever covers the widest set of interests wins. This means that each channel would be targeted at a different interest, so rather than a dozen top 40 pop stations, you get one top 40 pop channel, one punk chanel, one industrial channel, one opera channel, one baroque channel, one reggae channel, etc.

Each radio must have a buffer able to record several seconds of audio. When reception is lost, the radio keeps playing out of the buffer, until reception is restored. Of course each radio transmission would therefore be lagged by the number of seconds your radio is capable of buffering.

Both CD Radio and XL offer 100 different "stations" respectively, with CD Radio dividing it nicely, 50 for news, 50 for music. Both companies have already produced primitive station lineups already: XL Radio [amrc.com] and CD Radio [cdradio.com].
Even though I have no direct evidence, I imagine many of the stations to be similar to National Public Radio (NPR) in their broadcast procedure. NPR reports news that is broadcast all over the nation, so reporting local events or weather is ineffecient for every single area around the country. Instead, NPR gives regional broadcasters space within the nation-wide program (anywhere from 5 to 60 minutes) to report local news, sports scores, and weather. If the new satellite radio companies really expect people to give up their old radios for the new deal, then they'll probably come up with a system similar to NPR's. The logistics of such an endeavour are beyond the scope of my knowledge.
