Ahhh but a tiny trak or opentrak in mic-e mode is great for skywarn....
just hook a TNC up to monitor the output of your local repeater and collect
the packet racket from teh mic-e bursts and relay them over to 144.39. If
you use call sign swapping on the TNC (like a kpc3 or T2 tracker), you can
make the callsign of the TNC the numeric equivalent of the frequeency of
the repeater.... Ideally, the first hop W1-1 will be call sub'ed with the
repeater freq and then you know how to contact him by voice. And when a
guy says he sees a funnel cloud to his west, you know where that is!

Another project, still in beta version is APRS-Deluxe by Radek SQ2FOA.
- mobile in Mic-E format with SmartBeconing and display
- fixed with capability of digipeating, telemetry (5 analog), weather
(Ultimeter, WX-200)
Some pictures on my web http://www.aprs.pl/foa.htm and project simulator
running under Windows http://sq2foa.republika.pl/deluxe_win.zip
Now, I do the wx tests as AB9FX-8
I plan to take my unit to Dayton this year, if anyone is interested to see
it in action.
73!

You are both right here.... strictly speaking nowhere near everyone owns a
laptop, but the demographics of computer ownership for the last six years
have show and steady unwavering trend towards laptops.
There was a recent survey from a very large university ( I just cannot
dredge up which one right now) that has done a 'technology survey' of
incoming freshmen for the last 10 years. The first year of the survey it
started off with 70% of them bringing a computer of some kind, broken up
96% desktop/4% laptop. Ten years later, in the Fall of 2006, the incoming
freshman (some 2000+ I think) had 99% bringing computers and 89% of them
were laptops. Apple Computer have announced several years ago that sales of
laptops had surpassed desktops and that margin is increasing, I believe
Dell has made similar announcements.
Bob's contention is not exactly right, but its pretty close to dead on in
the geek community!... come on... how often do you see without his laptop
and/or palmtop?????

I cannot imagine packet or satellite active hams without at least a clunker
laptop. I've seen them at Hamfests for at least 10 years for $5 to $10 or
less. Sure, none of them are the latest and greatest light-speed
bazillions of gigabytes, but as long as they had a serial port, a keyboard
and a display, then they were just fine for packet or satellite.
Everything back to a 286 can run Satellite tracking programs or packet.
They make great assets in any shack.
In fact, I have even used them without displays, and just plugged in an old
monitor. That way, they are simply small keyboards that take up minimum
desk space, run on flea power, and are handy for many apps... I use them
so that they take the summer lightening strokes and not the family PC.
When it smokes, put in another one.
APRSdos can even run from a single bootable floppy so laptops with bad HD
drives are even useable. So can Instantrack, one of the most venerable
AMSAT tracking programs available. Though I stopped using them mobile back
in about 1999 when the Kenwoods came out, because the front panel of the
kenowood gave me most of what I needed without all the bulk.
For $5 or even for free, I cannot imagine a better ham radio investment for
someone that does packet, APRS, or satellites, or other routine needs than
an old laptop that has a serial port. Sure, it wont run any of the latest
state-of-the-art memory intensive apps, but then, some tools don't need all
that for some simple tasks.
Just one perspective. Though I will get hammerd hard by the geeks on this
sig who use all the latest stuff... ;-)

Sorry if I came down a bit "hard" on you... but still... ".. for someone
that does packet, APRS, or satellites..." In today's world, for all
practical purposes, when you day "packet" you mean APRS. It's by far the
most active VHF packet activity out there. Maybe there is some HF packet
cluster activity still around, but most BBS's are long gone.
I did have one of those old laptops.. a 286.. but I threw it away.. a
*long* time ago. I see no reason to get another box... that likely has
either NO battery, or a battery that does not hold a charge.. that may have
some other problem I can't see. I've never seen old laptops for as cheap as
you have (most of what I see are $200 to $400 and up).. but I haven't
looked that closely. I own two desktops and that works for me.
