Like you said earlier, Henk. It's a client problem. :)

I have a strange problem. This morning when my wife was driving to work I
noticed that about 45 seconds-1.5 minutes after her posit came through my
machine it was repeated again but had moved to an illogical position. I
captured the last two packets.
Here are the facts about the packets below: the car was parked and the
speed was zero. I saw her beacon with the icon of a small red car in
UI-View. About a minute after this posit I got a second posit via the
Internet that has changed her icon from a car to a dot and now she is
moving at 79.4 mph and is located about .5 miles from the correct location.
Am I correct in thinking that this may be a mangled packet problem? If so
is K4RY the likely source? If not are there any suggestions for tracking
the problem?
( packet that produce the incorrect loctation from UI-View)
KE4JQM-9>SRTY6V,AB4KN-2*,WIDE2,qAS,k4ry:
`oCl"x>/"5M}
(both packets from UIHistory the first is the one I heard direct from
KG4OLD-2)

UIHistory and notepad as a black square.

Here are more examples of the same situation. In this case K4RY seems to
have heard KG4OLD-2 direct.

Either K4RY or an IGate connected to K4RY has FILTER ON set at the TNC.
The dropped character is one that is less than 0x20 (a space) or it is a
0x7f. Either way, the IGate's TNC is dropping the character due to
filtering being turned on.
This is a good time for this to be posted again:
IGATE OPERATORS:
Check your TNC initialization files. Make sure ALL filters are turned
OFF! If you do not, valid Mic-E packets may be mangled.

Would it be a good idea to include something in OpenTRAC that could
indicate what kind of assistance is required in terms of say police,
fire, EMS, the kegman etc.?

I have limited knowledge of this, but you're welcome to what I do
know. Maybe this will get some discussion going to help fill in the
blanks:
TinyTrak-I/II/III: Must program that message into one side or the
other in the configuration (via a computer), then during operation
set the toggle switch to that configuration.
TAPR MIC-E: Rotate the message selector to the last position.
Probably TAPR PIC-E?
Kenwood TH-D7A/TH-D7A(G)/TH-D7E
Kenwood TM-D700A
Tigertronics TNC's?
The only devices that can generate these transmissions are devices
capable of sending MIC-E formatted packets. Regular APRS packets
have no facility for carrying this information.

How about adding a flag such as RESPONDER for those who feel a need to
indicate that they are responding to an emergency. It might be useful.
For example..you "hear" a station beaconing EMERGENCY, and you look at your
mapping application showing the stations near them - and see one near them
beaconing RESPONDER and moving in their direction.
I'd also second the EXERCISE EMERGENCY flag.

I wish all APRS programs would look at the TO field of APRS messages and
respond to messages sent to EMERGENCY just as if it were coming from a Mic-E
packet. In fact, the Message packet is ideal for this as the user could
actually state what the emergency was! APRS+SA currently looks for message
to fields of EMERGENCY, ALARM, ALERT, WARNING, WXALARM and EM. EM is short
for EMERGENCY so that it can be entered quickly on a D7/D700. Unlike Mic-E
or course, the position packet is in separate, and perhaps not yet received
packet, that is the downside. But that is the only downside I currently
see. Again, unlike Mic-E, some indication of that the emergency actually is
can be included in a message. Brent KH2Z

Only newer versions do that, the TH-D7E accepts it just like any other
beacon with no confirmation at all. The only thing that will make people
think twice is the use of capitals and exclamation mark on "EMERGENCY !"
and capitals on "PRIORITY", where the others start with a capital but are
for the rest in lower case.
Kind regards,
Henk.

Frank Bauer mentioned that ISS packet is back on the air.
I just checked the APRS page http://www.ariss.net
and sure enough, I see one station that digipeated through ISS in the
last few hours... VE3TZS. But that was now 22 hours ago. Of course,
nothing shows up on that WEB page unless people are monitoring 145.800 and
feeding the data to the APRS-Internet system. Maybe all the IGates have
gone away. If ISS packe is back on the air, then it might be a good time
to check those ISS-IGates and get them back on line...
