Steve Dimse posted a message a few weeks ago notifiying that open access to
the findu MySQL server(s) was turned off due to performance problems
resulting from runaway/malicious clients that he couldn't track down.

Hi All-
Hurricane Season hasn't even started and we have our first wacko plots
out on the ether to confuse and ofuscate Ana's position. Every year it
is the same problem- either someone can't convert from degrees and
decimal degrees (which the hurricane center uses) to aprs format , or
they are just guessing the position.
There is no fundamental right to be wrong here. Ever tried to explain
to someone in a Emergency Operations Center why there are 6 widely
differing locations on the aprs map for a hurricane? Makes us look
like amateurs in the worst sense.
Based on icon, position, and name the offending packets could be killed
automatically. This is a drastic step, but self-policing is a dismal
failure in this area. A far less draconian method would be to filter
the data on the client side. With xastir I can do that before Hurricane
season starts. I would encourage the various authors to consider
adding the ability to plot only from trusted sources.

FYI: APRS+SA allows position entry in UTM. And while the display of position
data is in Lat/Long, is you hover the cursor over a position report, the
popup tooltip window will show the position in Lat/Long Decimal Degrees, in
Degrees/Decimal Minutes, UTM and in Maidenhead Grid. Brent KH2Z

I can't tell you how many times I've given an APRS demo to some NWS office
or public service people and said how great it was that you could create an
object and it apear on everyone's screen within seconds. And show them how
great it was that if their station failed, someone could click on the object
and move it, only be be met with disapointment from them... it seems that
NWS people dont like the idea of someone moving "their" funnel cloud. What
we need is a way to authenticate the source of the info so that the clients
don't allow (accept/ display) unauthorized posit changes in objects.
I think perhaps a better solution would be to have the client software
display a list of all stations who had transmitted an object with the same
name when you hooked it (or double clicked). You, the end user would select
a series of check boxes which indicated which sources of this object where
considered reliable. Just because those objects are on the air, doesn't
mean that your client software has to display them. You could select to
plot only ANA from the known good source, and not N4BAD or KD4LID's
representations of ANA. (are those real callsigns??, hoping not to pick on
anyone too badly) ;-) In this way, not just storms, but hey, how many WATER
trucks, or POLICE1, or RUNNERs are there at any one time?

Subject: Been reading the posts and have a question
From: "Dakota Summerhawk" <dakotas@dotorg.org>

Ok so maybe I am not understanding this right but can someone explain
the point of NOT transmitting your position for stationary objects? I
mean I can understand the reason for not having a high rate of report
but not transmiting at all kinda defeats the purpose of APRS altogether.
Maybe someone can expain this so it makes sense to me. Another question
I have is the tracker is set to report at 2min all the time, is there a
program that would keep the report rate at a longer rate when parked and
then shorten it when mobile? Would be nice to avoid the traffic crunch
with a parked truck with a 30 min report rate and a 2min report while
moving without haveing to switch them manually. Is there such a beast?
Let me know.
