Hmm, well here is a picture of the KC5ZRQ-6 station.

I think you could probably buy the IC-V82 radio with D-STAR for about $320
USD. I've got a picture of the KC5ZRQ-2 station somewhere, but I can't
find it right now. I'd imagine that it would cost about the same amount as
a typical APRS I-Gate station.

I must disagree on that assessment. The IGate I run uses spare equipment
that had no other purpose. There's not a lot of spare D-STAR stuff yet,
nor even used stuff.
The only expenses where I specifically spent out-of-pocket money for the
IGate was the power supply (and soon a backup battery - the UPS the power
supply is plugged into does not work well anymore, so it's time to build a
proper 12V power supply - and to run the computer and network equipment off
of it).
If I wasn't run an IGate with the IGate computer and radio, the computer
would probably be disposed of and the radio would probably be sitting and
gathering dust (or sold at a hamfest).
But I'd agree if you bought mostly-new equipment, the IGate station might
even cost more money (price TNCs!).

KC5ZRQ-2 is the D-STAR I-gate. It is running the DStarInterface for the
javAPRSSrvr. I think that lots of APRS I-Gates use javAPRSSrvr. The
computer is a Dell Optiplex with a Pentium 3 - 500 MHz running Windows XP.
It was donated by Lubbock County to the Lubbock RACES foundation. The
radio is an Icom IC-2200H, which with the D-STAR module, probably cost
about $350.
By the way, even sitting in 100+ degrees Fahrenheit, the Dell Optiplex has
never crashed. It is running javAPRSSrvr, Echolink, Echotime TTS+ and
Weather Exchange software on it. It also runs some diagnostic software
that monitors the wireless network. Although it is connected to the
Internet, if the Internet connection were to be lost, and even if the power
went out for a short time, I could still use the server, via Wirless LAN,
with the KC5ZRQ-1 APRS I-Gate.

Sounds very similar to my setup, except I'm using a 700 MHz Optiplex
Pentium III, run Linux, and use a different radio.

My IGate also gets quite warm in the summer (and down to about 50F in
winter for the computer, down to probably -20F for the radio). Not ideal
conditions by any means, but things seem to keep working fine.
I can't say enough good things about the Optiplex. It's been very stable -
I did swap out the CD ROM, but I can't remember if that's because it failed
(did I mention it's VERY dusty here?) or because I wanted a CD-R in it
years ago. It's not all that fast, but, heck, it's over 5 years old!
(besides, it's plenty fast for 1200 BPS packet)

I can't say enough good things about the Dell Optiplex GX1. I went up
there last week to install a new soundcard for the Echolink and I didn't
need any tools. And yes, my location is very dusty also. Inside the case
was relatively dust free. Most of the dust is on top of everything else.

PLEASE no! If someone has a PC to run UIVIEW then they should connect to a
TELpac node and do their email directly! The conversion between the
WinLINK system and APRS called APRSlink is inneficient, and was ONLY
designed for those people and those special circumstances when the user had
no other message means available to him except a D7 or D700 radio.
Using Uiview to access the WInLINK system through the APRSlink, is
something like calling your Mom long distance and asking her to communicate
with your wife in your next room by mailing her a letter via the post
office...

It is inefficient when used with APRS using AX.25 and digipeaters, but it
is efficient when used with D-STAR to communicate directly with the I-Gate.
How would I connect to a TELpac node and do email directly if I'm not
connected to the Internet or I don't have packet radio capabilities?
I may have a PC to run UI-View32, but I don't have it connected to the
Internet.
As far as someone writing a plug-in that would work with UI-View32 to
improve the readablity of APRSLink email, it could be designed to only work
with D-STAR since all D-STAR traffic inserts "DSTAR*" as if it had been
passed by a digipeater.
