Re: [Gumstix-users] Gps on gpstix

What antenna are you using and where abouts are you? does it take very 
long to get a fix? I made the modification also and now see the correct 
voltage off of the sma connector. But i'm still having such troubles 
getting the gps to get a fix. Its weird, some days I can take it outside 
and get a fix within 5 minutes, sometimes it takes up to 45 minutes..and 
sometimes it'll sit for hours getting no fix at all. Always sitting in 
the same place, which is a place where 2 other gps's get a fix in under 
60 seconds.

I'm using the antenna from sparkfun and am starting to thnk that it 
could be the problem, has anyone made this modification and gotten a fix 
with the sparkfun active antenna?
