XM Plug-and-play tuners, with their home-to-car-to-boombox flexibility, are great, but they're not truly portable. Delphi's new MyFi - the first entry in the XM2Go line - is . The size of a typical MP3 player, the MyFi makes satellite radio as easy to take along as AM and FM. While you're out and about, you can listen to all of XM's channels in Live mode, and a Memory mode lets you record up to 5 hours of programming while you're asleep or otherwise occupied. The complete MyFi kit - with home and car adapters, earbuds, a carrying case, and rechargeable battery - is due in mid November at major retailers for $349 (list).

SIRIUS The biggest problem with listening to satellite radio at home can be receiving the signal. If you don't have a clear line of sight to the satellite, even a tree branch waving in front of the antenna can cause a dropout. Sirius has a solution - the Echo wireless signal-distribution system. Wed the transmitter to an outdoor antenna with a clear line of sight, then locate receptors wherever you have satellite tuners in the house. The signal is said to have a range of up to 100 feet and easily passes through walls. The Echo system is expected to be out by Christmas at a price to be determined.
