Yahoo groups have a problem that Yahoo itself recognized and they say they
are working on it.

Yahoo experienced a system failure. They've put out notices to all of
their groups yesterday. The problem does not affect ALL groups and they
are working to run down the source of the problem.

That is exactly what APRS objects are all about. Just place them on the
map, and a CLICK and DRAG is all anyone with new data has to do to update
them. This gives you the GUI and the instantaneous update for everyone to
see the result in real time. If there are 10 objects at state X, then
everyone can see them on the map there.
Yes, it is manual, but it only takes a second for ANYONE to move an object
from where it is, to where it needs to be so that all can see And being
manual, they can be placed so that all can be seen..
If you were running APRSdos, these objects would move by deadreckoning so
they only needed to be updated when they stopped or whatever. This would
give you instant visibility to where everything was and approximately their
progress between stages.
But be warned that Uiview is not good with large numbers of objects from
one station, so either spread out the load of updating these objects or use
some other client.

Subject: [aprssig] KPC-3+ Telemetry from Anywhere!
This web page summarizes all the ANDE telemety trends since launch.
http://www.ew.usna.edu/~bruninga/andeTemps.html
Not only does this reveal neat things about ANDE, but more importantly
these plots show how simple it is for just about ANYONE to throw this kind
of data together (from ANY device) if the data is transmitted anywhere in
the world on APRS. That web page summary took me under 30 minutes to
write.
Look at the web page SOURCE and you will see that these data plots are
simply CALLS to the global APRS data system at Steve Dimse's K4HG's
FINDU.COM data base. This data base maintains every APRS packet in the
world ever transmitted (I forget how far back it goes).
But if you have any application that is transmitting APRS formatted
telemety packets (any KPC-3+ TNC), anywhere in the world, the data is not
only available in real time, but also is avaliable in PAST time too thanks
to the FINDU.COM live database.
This means you can throw together a KPC-3+ TNC, a radio, a power source and
some 0-5volt sensors, stick it anywhere in reach of the global APRS system,
and without lifing a finger, you can monitor it (see above) from anywhere
in the world and go back in time to see anything you want. Plug a GPS into
it and you can watch it move on APRS too.
This is why we made PCSAT1, PCSAT2, ANDE and RAFT as simply flying KPC
TNC's with downlink to the APRS linked ground stations. The telemetry then
is a done deal because the global infrastructure is already in place, the
data base is in place, and the plotting stuff is all in place.
As an example, this URL call to FINDU.COM will show the battery voltage of
my KPC-3+ digipeater over the last 10 days!
http://www.findu.com/cgi-bin/tele2.cgi?call=WB4APR-1&last=240
To see the same plots from your KPC-3+ TNC, just put it on the APRS
frequency, simply change the CALL to your KPC-3+ and/or change the
"last=240" parameter to any time period you want, and you can see your own
telemetry, anywhere, anytime. Of course your KPC-3+ TNC has to have been
beaconing telemetry (see the TELEMETRY Beacon command).
Anyway, I don't think everyone is aware how simple this stuff is. SO I
just thought I would share it.

It could look as if they didn't have any knowledge of the countries at all
- a bad thing for a company selling maps. But, well, Precision Mapping is
no practical mapping tool outside north USA and Canada.

It arrived here with Spam in the heading; I should have removed that word
when replying, though (but I must have forgotten that).
According to the headers in your original message when it arrived to
me, this one is the only one with a spam score higher than 0,0:
||X-tis-spam: score=17.69330 (701302,709999,704425,701799,704341,703788,

It's going through a couple of spam checks, but the "X-tis-spam" line was
almost at the bottom of the headers; probably a very early checkpoint.

No conspiracy! Just the limitations of the map display. Each symbol has
it's callsign as a flag to the right. The tail of your call is being
covered up by the digistar symbol for one of the four stations just to the
east of Spencer Gulf. Apparently your posit arrived at my copy of UIview
before the stations to the east of you sent theirs. Last man in always
winds up on top of one of these visual "pileups". [Actually I was surprised
at the number of digipeaters in VK!]
Perhaps I should create a zoomed-in closer view just for "South East
Australia & Tasmania" that would spread out the mass of stations in the
area enough that their legends wouldn't overlap. Or I could horizontally
tile two zoomed-in screen caps to produce "South East Australia & New
Zealand". (The North Island looks as through it could also use some
spreading out.)
