yeah, my XM radio works even when the garage door is shut. otoh, i think it does pick up a satellite signal but switches to repeaters in urban areas. i think, for XM at least, the repeaters are designed to improve reception (eliminate intermittent signal loss in populated areas), not to completely eliminate the direct satellite downlink to subscriber devices. for a while i had a home XM unit (made by Polk Audio) with a special roof antenna. that was definitely a satellite signal. there was a special utility that displayed the sat signal strength on the TV. it had to face a certain area of the sky with unobstructed line of site to get a good signal, just like a satellite TV dish. even this unit would pick up the repeater signal indoors, but a much better signal was obtained using the satellite antenna on the rooftop with proper positioning. Polk Audio's component unit for XM Radio was a good start for this market, but i think it has been effectively killed because now you can get XM/Sirius through sat TV, practically for free and with no extra equipment. i must say, i find it somewhat hard to believe XM and Sirius have blanketed the globe (or even the US) with enough repeaters to provide full coverage without satellites. i have also read that XM and Sirius have very different repeater designs. i forget the particulars, though.
