Teh standard is the Gamin GPS 18x (make sure to get a newer unit or you
will have to upload a patch to it to fix the problem that it sometimes
sends teh nmea sentences too late). The Sure I am getting worried
about-- I thin kthe antenna they send with it is defective sometimes.
Bill,
Yours is the only Sure I have heard about with (perhaps) an antenna
problem. Whilst bearing in mind that this is a consumer-level antenna,
have you asked for a replacement if your unit is less than a year old?
As you say, for some considerable time Garmin was sending out GPS 18x LVC
units with faulty firmware. Version 3.70 is OK, though.
Whilst the Oncore UT+ which Chris mentions may have better ultimate
performance, I don't think you will see the difference in an NTP
application on the great majority of PCs. It doesn't come with an
antenna, tracks only 8 channels (at least that's one I found on eBay), and
also requires a connection lead to be assembled. Looks nice, though!
Cheers,
David
