I'm sorry to be so late replying to this thread. In fact, I did reply
to the thread, but apparently my reply only went to Bob WB4APR, not the
list. I will try to re-construct what I wrote from memory, since it's
also not in my 'sent' box.
Bob was replying to these questions:
> >/ How come you want to run a TNC mobile ? /
> >/ Why not just use a tinytrack or opentracker ?
/> Because the essence of ham radio is two-way communications. Because
the essence of APRS is situational awareness. Having a channel that is
the be-all-end-all of information on all ham radio activities going > on
in the immediate area.
Agreed. The mobile situational awareness that APRS provides is what
inspired me to create the heads-up APRS terminal called HamHUD
(www.hamhud.net) back in 1997, before the Kenwood D7/D700 came out.
It's why our team stuck with it, refining HamHUD in four iterations over
nearly ten years.
And it's why we're unveiling a demo version of our latest iteration,
HamHUD V (pronounced "vee") at Dayton this year. Please come by booths
503/504/505 (Argent Data Systems / RPC / APRSWorld / HamHUD Nichetronix)
if you're going to Hamvention this year.

Bob's comments about the importance of 2-way mobile APRS serve well to
articulate the reasons the HamHUD team included the following features
in HamHUD V:
- Two virtual TNCs (one for internal APRS, one for an external APRS client)
- Seperate heads-up bitmapped display, as large as user desires (I'm
currently testing with a rear-view-mirror integrated display)
- Seperate user interface, on the microphone or a
steering-wheel-mountable wireless remote
- PS/2 and USB keyboard inputs
- Integration with external voice and APRS radios
I hope you guys will come by the booth, take a look, and give us your
