At work, it's all steel studs and foil-backed wallboard, and the windows (for a patch GPS antenna) are _way over there_. *sigh* I'd love it if someone would pay for my roof penetration there.

Does your cell phone work in the room? The CDMA time receivers work in the strangest places. The only places I've had no luck: - In the bowels of a big building along the mass tech corridor - when moved to a bad spot inside a fairly steel and concrete-heavy lab at the university of utah (works in other spots in the lab). But aside from that, I've got them working in network closets and labs all over the place. Worth giving a shot if you're really desperate to play. They're not quite as accurate as GPS (~10 microseconds vs. ~2-5 microseconds), but what's a few microseconds compared to sticking an antenna on the roof? (As a frequency standard, they're quite good. But you can't autocorrect for the CDMA propagation delay). -Dave -- work: dga@lcs.mit.edu me: dga@pobox.com MIT Laboratory for Computer Science http://www.angio.net/ I do not accept unsolicited commercial email.
