And sometimes you need to know what the weather is like at one particular
location. I'm a paraglider pilot, and I've spent hours driving around
between sites looking for favorable conditions. In this case, you're
interested in exactly what the wind conditions are at that site, because
they could be totally different over the next ridge. There's nothing like
flying around under a ram air inflated nylon wing to give you an
appreciation of just how much local topography affects micrometeorology.
Of course, there's still no better gauge of flying conditions than the
tried-and-true 'wind dummy', which gives rise to the expression heard so
often at launch - "Looks good. You go first."

And.... An Incident Command Post or the EOC should be isolated away from
the incident. This is where data collection should occur. Data coming from
the incident to the ICP or EOC is good and the more of it the better.

Alex, it's not about you arriving on scene. If you were part of a team that
was sent to a scene, I sure hope your leaders were smart enough
to know the environmental conditions BEFORE 'they' sent you. Remember the
key words...SAFETY SAFETY SAFETY. If it was a bio-hazard and
your EM's sent you to the scene down wind....or with NO DATA....you might be
dead!

I was hoping someone else would tackle this question, but since no one has
(publicly).
The "secret" has too many varaibles to delve into deeply in the APRS
forum. It depends on the soundcard, on the motherboard, and on the
OS. Windows XP is kinda hard since many legacy (Soundblaster) soundcards
use setblast commands in the autoexec.bat file. I would say use a
jumpered soundcard, but finding a recent motherboard with an ISA slot can
be a challenge. I would say use a non-SB soundcard like an ESS soundcard,
but many of them don't do a good job of working with various soundcard TNC
programs... An ISA AWE64 will co-exist with a PCI SBLive.
You can get two SBLive cards to work together, but it's not for the
meek... I have never tried it myself.
http://www.come.to/SBLive
Getting two soundcards to work together is almost as much fun as getting
two video cards to work together. The main problem is that if you put a
PCI video card into a system with an AGP video card, the PCI card is always
asserted as the "primary" video solution, when obviously you want the AGP
card to be the primary. Why they don't/can't make a motherboard with two
AGP slots is beyond me... At least they make dual-head video cards.

We respond to what we see. Unfortunately, the written word does not
convey a chuckle too well.. All too often, obvious clues are missed and
we end up taking what we see at face value.

This is why I'd like to see a 4-port DSP PCI card. Hey, TAPR's looking for
'enabling technologies'... how about taking that on as a project?

A while back it was announced that TAPR was working on sort of a TNC
project. It was in one of those "ideal TNC" threads. I think we were even
discouraged talking about what we would like to see in the next generation
TNC until some formal announcement on the project was made by TAPR.
Perhaps an update on the developments in this area from TAPR is in
order?

So I got my prototype coherent phase FSK encoder built, but my waveform's
kind of funky. Without a digital storage oscilloscope, though, it's hard to
pin down exactly what's going on. I believe my 'scope may actually predate
the invention of '1's and '0's. In any case it takes half an hour for the
tubes to warm up enough to get anything close to a stable sweep.
So now my question is this: Can anyone recommend a good PC-based
oscilloscope, or would I be better off watching eBay for a used HP or Tek
'scope?

Darryl, VK2TDS, has been leading a discussion of new TNC designs, but
there's no "official" TAPR project yet. I'll let Darryl fill in on the
progress of that group if he'd like.
But I do want to reply to an assumption that folks tend to make. TAPR
doesn't have a bunch of engineers in lab coats just waiting to jump in and
turn the back of someone's cocktail napkin into a spiffy new product.
Heck, we don't even have a lab coat.
Our goal is to help take projects from the 80 or 90 percent stage to
something that's marketable. We can provide a second (or third) set of
eyes to help scrub the design, and we can help with documentation and parts
procurement. We can share painfully-gained wisdom about the development
process. Sometimes, we can provide a bit of funding for alpha and/or beta
runs. We can provide a sales channel to get your brainchild into the hands
of others.
But every project TAPR takes on begins from the perspective of "I want to
do this, can TAPR help?" rather than "TAPR should..."
