I suspect I may be getting seperates bytes correctly, and then glitching on consecutive bytes by missing the second byte. My program has the time part of the $GPGGA string on the text LCD. and it reads like

060715.

060717.

060720.

06072.

060722

06725

This might be why I can detect $GPGGA every 3 seconds or so, and get a few garbled latitude longitude string.I will continue with that signal tap idea.
