[aprssig] What is the best GPS Data RX on the market now?Answer: GPS 18x

Exactly the altitude limit that really does not concern me too much since I
don't do any balloon stuff. I'll see where else on the net I can find a 18x
for a good price, I am guessing they can be found for about $50-$60.

Next thing I got to do is take the GPSII and GPS V waypoints that I have and
suck them out of the units before they totally die. Displays are going south
and I am getting some sort of wierd errors when the GPSII locks on. Friday
my wife was in the other county then appeared in Central Mexico and just sat
there, location was wrong but I think the timestamp continued to be correct.
The Kenwood continued to Xmit the location and I think it's smart enough to
look to see if it's a valid sentence and xmit or not. I'll probably buy a
Nuvi for actual navigation and got to see if I can transfer the old data
over to the new ones, I have about 13 years of waypoints from accross the
country saved up which I would like to keep.

        Can you be more specific?  I have multiple GPS 18 units and even one
GPS 18x running, with some of them attached to D700s and I've never had a
problem.  The only issue that I've heard about is that the very early GPS
18x units (the 18x is the high-sensitivity replacement for the now or soon
to be discontinued GPS 18) had an altitude limit in that they would no
longer report altitudes if the unit went above 60,000 feet, but that issue
was resolved with a firmware upgrade several months ago.  I just looked at
Scott's page and it still mentions this bug, but that page is outdated since
the bug has been fixed.  Even if you have one of the early GPS 18x units you
can upgrade the firmware which is available at garmin.com.

        I've had nothing but excellent results with both the GPS 18x and the
older GPS 18.  I'd highly recommend using the GPS 18x.  It's been reliable
and has very fast acquisition.

Scott's web page and it seems Garmin has a problem currently with the GPS18
