PHK, That's probably true. The original GT and UT receivers were identical physically, but they can both be loaded with any version of GT+ or UT+ firmware. The UT+ hardware is slightly different in that Motorola added a ceramic filter to the front end for better selectivity. As with the original UT and GT, The UT+ and GT+ don't care what type of firmware is loaded. The only concern is that if you squirted GT+ firmware into a UT+ platform you would lose the RTCM input as the UT+ PC board didn't have this clad. In hindsight it's probably a good thing as the differential performance of the Motorola Nav receivers was always way too jumpy.
The common hardware platform did reappear with the M12+ receivers. All M12+/M12M receivers are identical physically (not counting the battery/no battery option). How they operate is entirely code dependent.

The interesting thing is that as a result of me jumping on Motorola, I ended up with what I think is GT hardware with UT+ firmware (or some such). -- Poul-Henning Kamp | UNIX since Zilog Zeus 3.20 [EMAIL PROTECTED] | TCP/IP since RFC 956 FreeBSD committer | BSD since 4.3-tahoe Never attribute to malice what can adequately be explained by incompetence. _______________________________________________ time-nuts mailing list time-nuts@febo.com https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts _______________________________________________ time-nuts mailing list time-nuts@febo.com https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts
