I also wouldn’t want to do any serious data entry/review on a 20x4 screen. Just my opinion.

<p>I have a D700 in the mobile, but the native user interface is so
god-awful that I never use it. Nobody in his right mind is going
to compose real messages on an interface that functions like a
Dymo tape label maker. I ALWAYS have my Panasonic CF-51
Toughbook connected to the D700's serial port, running a real
APRS app with a REAL keyboard and usable display. The only time
the D700 every operates in stand-alone mode is when I'm on the
road, and stop for the night. I take the laptop out of the car
for security, and the D700 acts like as an unattended dumb
transmit-only tracker overnight. <br>
</p>

<p>By the way, the D700 TNC is a REALLY mediocre-performing device
as well. About two years ago, I did some testing of APRS and
digipeating in the mountains west of Denver. This was in aid of
possible vehicle-tracking support of the Evergreen (CO) Jazz
Festival. This area is spectacularly scenic, but is a nightmare
from an RF engineering standpoint. There are few line-of-sight
paths, and lots of multi-path distortion from signals bouncing
around an L-shaped canyon and reflecting off mountain sides a
thousand feet higher than the town. I had an ammo-box tracker
functioning as a test transmitter at the proposed digi site
beaconing every 30 seconds (not on 144.39!) while I drove around
the area logging the number of missed beacons. <br>
</p>
<p>I had both the D700's internal TNC and a soundcard soft TNC
connected to the D700's 6-pin mini-DIN "data" port going at the
same time. I had one copy of UIview32 connected to the D700 TNC,
and a second copy connected to the soundcard soft TNC In
several test runs, Direwolf and the UZ7HO "Soundmodem" software
TNCs copied almost THREE times as many beacons as the D700
hardware TNC. <br>
</p>
<p>Direwolf is available for Linux, -- it will run on a Ras Pi's
sound system. No need to cripple the receive performance with an
archaic DC-power-hogging hardware TNC with a fraction of the
receive performance. <br>
