Sirius ( SIRI) rose 5% in early trading Wednesday, buoyed by news of its first quarter of positive free cash flow.

The New York-based satellite radio broadcaster said it ended 2006 with just over 6 million subscribers. That's in line with the reduced guidance the company offered back on Dec. 4 , when Sirius trimmed its year-end user target to around 6 million from the previous 6.2 million-subscriber forecast.

Shares rose 18 cents early Wednesday to $3.72.
