The D700 is a great tool for exposing people to APRS, but it is
limited. Two of the issues I've run up against are:
1. The D700 knows nothing of Smart Beaconing. It just keeps beaconing
at a fixed rate no matter what's happening to the location, speed, or
course of the GPS data being fed to it.
2. To the best of my knowledge, the APRS software that works with the
D700 requires that you put the radio/TNC into "packet" mode. This
takes the unit out of "APRS" mode and disables the built-in APRS
functions of the radio/TNC. That puts the APRS load on the software
running on your computer. No problem unless you plan to switch back
and forth. In my application, I want the tracker running all of the
time when the vehicle is running, but only occasionally will I have a
PC hooked up. Sure, I can make the switch at the radio/TNC, but I'd
prefer something more seamless.
It'd be great if there was a way to let the D700 continue to run in
APRS mode and then have a mapping program that pulls the positions
from the D700. I haven't seen anything like that out there.

What does UI-View give me that ARPSPoint doesn't?

OK, there's one advantage.

What is Tracker2?
I don't have a "mapping GPS unit". The mapping feature of my Garmin
GPS II+ is primitive. And I don't want to spend several hundred
dollars for a mapping GPS with limited map memory to duplicate what I
already have in a PC running a mapping program. The AvMap mapping GPS
accessory that Kenwood is pushing for the D700 looks great, but it ain't cheap.

Yikes. I don't think I need to plot APRS positions on Topo USA. But I
would like to share GPS position data between the APRS solution and Topo USA.

Yep, that's what it may come to.
Thanks for your input!
