If you are on the 15th floor of a 30 floor building then you are going to have troubles with the GPS in any case. Any view out the window will have less than half the sky visible. Sometimes there may not be enough satelites visible for a lock. *Sometimes* my GPS 12XL will establish a lock inside my wooden house with asphalt shingles. > BTW, the radio geeks at http://www.tapr.org/tapr have a low-cost kit that > looks pretty easy to assemble for use in your home network. Was it the GPS-30PC TAPR bought closout from Garmin? $99, http://www.tapr.org/gps/index.html. *Exactly* the GPS you would want for this task. Bare minimum GPS in a weather tight case with integral antenna. No display. Only has NEMA serial interface. -- David Kelly N4HHE, dkelly@nospam.hiwaay.net ===================================================================== The human mind ordinarily operates at only ten percent of its capacity -- the rest is overhead for the operating system.
