I'd lost track of who it was that originally suggested the WAS7-7 idea but it
looks like it was Bob. I've also turned the trimming up on the SEA digi so
that it is now fully compliant with the local RF network and is trimming
packets at wide3-3. Here's a sample packet:
aprs: fm N7UUT-12 to TW1PQS via BALDI* WAS6-5* WIDE3-1 ctl UIv pid=F0(Text)
len 15
Only problem with it is that it is hard to tell which digi it was that did the
trimming. SEA did the trimming and if I had to guess based on this packet
I'd guess that BALDI had done it. Which it didn't. So I'm gonna change it a
little farther so it would look like this:
aprs: fm N7UUT-12 to TW1PQS via BALDI* SEA* WAS6-5* WIDE3-1 ctl UIv
pid=F0(Text) len 15
Opinions? Thoughts?

For those of you familiar with Weather Display from NZ and run a linux
platform check out Brian's new application. This is the first release
and I am still downloading but I thought I would let everyone know.

Yes, never begin a path from altitude with RELAY. It causes hundreds if
not thousands of users radios to key up all at the same time. This is bad:
1) Causes the packet to experience tremendous collisions and fratracide.
2) Every home station and mobile that hears it keys up:
a) THis blocks the 2 meter band for those users who may be listening
to other 2m channels at the same time... on other radios
b) Causes TV interference and other QRM. (My wife doesnt mind
a garbage picture for one second every 30 minutes, but she HATES
it when my TNC keys up every minute which your balloon would
cause...
>>Any suggestions on how this should be set in the future?
You bet. Dont begin with RELAY...
Thanks for asking...

It is tied to my IGate not a digipeater. The traffic page only shows what
is monitored by the Igate's TNC. We also use the probe called 'YUMALOAD' to
do what you described earlier. It uses the PHGr and gathers data on the
network, and looks for packets based on success. Last I looked we had 120
in 10 mins. Which is fairly close to what my IGate is also monitoring.
UI-Traffic is a fairly slick program, and can be used several different
ways. As a 'Probe' or a 'monitor' or both. I chose to use it as monitor for
my Igate, since someone else has the probe running at a different
location.
As Dave said earlier, the web page is updated every 15 mins. However, the
program monitors and displays packets per min., hour, and daily totals. It
also monitors other probes. Nice to see how efficient a network operates in
real-time.
Ui-View (used as an IGate) has a very nice terminal window that can be
adjusted to view only RF traffic. That is the same traffic that is counted
by Ui-Traffic. I've watched both screens... they compare prefectly, as seen
by both programs.
Winaprs has a traffic html page that can operate on a separate port
(14439). It displays all traffic, stations, etc. RF and internet feeds
combined. Ui-Traffic only monitors RF. Kinda slick <g>. I have no idea why
I'm running it. I imagine we will hear from someone that uses the 'probe
enabled' and get more input. We both are learning. I can tell you that if
the graph display is mostly 'Red', your RF network has serious problems.
Packet success is low. But I don't have to tell you that <g>.

Not an official answer, but I think if you were seeing the packets direct
on RF, then that is great! It isn't like we have 100 balloons up every
day. BUT, you might consider taking the RELAY off the path. The only time
that is really going to make any difference is maybe when it gets very
close to the ground and by then you already have a general idea of where it
is so you can go and retrieve it. VHF being line-of-sight (mostly) means
that even when your balloon is 100 ft off the ground, it is probably in
sight of a digipeater (at least in most places... I don't know about the
density of digipeaters in the west).
Just a thought, though. So when can we expect another run? Do you use the
same callsign for the tracker each time? Did you ever find the last one?
You can reply off the list to these questions.
Thanks,
Eric KF4OTN/3 (In MD right now.)

Gents,
I have just re-done my site with lots more to come yet.
Hope this inspires others to have a go.

Does he have a mailing list or anything specifically setup for his Linux
build? I glanced briefly on the website and didn't find much other
than a comment and download link. There's a broken link to "egroups
community" but that's all I saw for program-related discussion.
It's definitely alpha quality. ;-) In my case, it opens the com port
fine but doesn't display any data from the Ultimeter 2000 (after
arm-wrestling the menus to setup everything). And there are many
user-interface oddities to be sure... All in all, I've seen much worse
alphas. It runs without crashing and that's better than some programs.
