I have frequently used my "MyFi XM Satellite Radio" as an all night sleep sound source using the external antenna on a bedroom window shelf, with the indoor docking station and AC adapter plus a IPOD type battery speaker system. I have gotten an OK signal. You can run the small antenna coax out a window with the screen nearly shut to the antenna on the ground nearby, too. I also have a docking station and antenna in my truck, and a pair of headphones with a built-in satellite antenna for my exercise walks (on the internal rechargable battery).
60's music will push your walking pace, and Old radio shows and the Audiobook channel are great driving boredom breakers.
