XM Satellite Radio said Tuesday it will sell a portable satellite radio with a built-in antenna that can record up to five hours of programming.
The 7.3-ounce device will act as a TiVo for satellite radio, letting users record one station while they listen to another, or record a station when they're not using the radio at all.
Users will not be able to download music from other sources.
The $350 radio, which will be available in early December, will ship with headphones and a remote control and come with kits to adapt it for home and car use.
XM has more than 130 channels and 2.5 million subscribers, who pay $10 a month. The radio will be manufactured by Delphi Corp.
