Overseas must be the rest of the world from your location :-). I can answer
for The Netherlands but I don't know much about the situation in the rest
of Europe.
First of all we have regular APRS:
On UHF we use 430.5125 as second APRS frequency at 1200 baud. Main reason
was that the Novice licensed HAMs were not allowed with packet on 144.800,
the main APRS QRG. I say "were", since CW is abandoned AT (Telecom Agency
which is the regulating body for us) simplified the licenses, allowing
Novices to use all of the 2m and 70cm band in every mode.
Even before the license simplification a lot of mobile Novices used 144.800
illegal since the coverage on 430.5125 is much less tight and 70cm by
itself also gives a significant disadvantage over 2m. Most novice fixed
stations were on 70cm. I occasionally use it too, that way APRS
transmissions will not (or less) infuluence the other receivers on 2m.
Besides that there is APRS on the Packet backbone systems:
This is part of an experiment and distributes packets acting as one big
single WIDE. That uses QRG's on mainly 23 cm, the point to point mesh that
connects the nodes and BBSses. Speeds as 4800 baud (HAPN modems, I never
experimented with this but I think it is manchester coded) for the older
links, 9600 baud FSK on most links (G3RUH) and some experimental links with
even higher speeds.
The Germans have a much better packet network that is also TCP/IP capable
(In the Dutch network it is semi working, only for short distances). They
implemented IGATEs on that network to which you can connect via RF. They
just use the same programs as for Internet. But I think our German friends
on the list can tell much more about that.
I hope this answered the question for our little corner of the world. I'm
curious however why you want to know this, do you have any plans in that
direction or is it just curiousity?
Kind regards,
Henk.

I have had the same messages . I am a registered winaprs user.
This has been occurring for a couple of months now.
I think they are coming from third aprs net.

I know that I have asked befoer but still no answer
who is the party sending the aprs-1 messages telling users to
get a registered copy of their software?
This happened before 3-4 weeks ago and then stopped after 2 weeks
since I have been registered from 1999 something is wrong. Do any
other igate users have this problem ..

I just started playing with a Palm and APRS, and have a question...
I have a couple of Palms. Specifically, a IIIc and a Vx. I can beam stuff
back and forth no problem.
But a friend has a Sony thing that runs Palm OS. I can't get the two of
them to even realize that the other guy is there. Does that mean I have to
get data between them via the PC? Or is something wrong.
Ok, and the maps... I realize they are kind of huge to transmit over IR,
but has anyone done it?

I haven't had any compatibility problems with my IIIc.
Try beaming to a mirror, or keeping about 1/2 meter distance between them.
There is such a thing as "too close" with IRDA, and your transmitter may be
on his transmitter's side. One side of the window is T and the other is R,
but there may not be a standard on which is which.. Too close, and your R
can't see his T well enough.

BtDT, it takes a while, but it does get there.
Start with a charged battery :)

They are not. These messages are being originated by aprsD. APRS-1 is the
"callsign" of first.aprs.net. While these messages are intended solely for
the station connecting directly to the aprsD server, other servers may
propagate these messages causing them to appear to come from any place. If
the message was addressed to your station and you were connected to
first.aprs.net, it may be the new version of aprsD that first is using is
not accepting the user login from some software properly.

Subject: Internet Packet "Mixing" from RF

I have been noticing this more and more since a new aprsD server poped up
about 4 digi's away. When a packet is sent out over RF my xastir gate will
send out the packets to the internet but it appears that a new aprsD igate
will also send out the packet. When I pick up the packet over the internet
(several different stations not just one) you will see the position or
beacon information along with the PARTIAL information from antoher station.
All of these will show that the igate is the aprsD one from several
counties away.
I have not contacted the gate owner yet, I want to find out more of what
could be causing this. Sometimes a callsign will show up as 4pkt-3 or GPS
or K4GP etc. etc. or the problem will be somewhere in the beacon or
position string along with packets from a totally unrelated station. Does
anyone know what causes this or a fix ?

Subject: APRSdos floppy?

APRSdos users (if any)
I'm considering a new release of APRSdos:
1) Is free. No validation numbers
2) Removes lots of stuff not needed any more
3) Fits on a bootable floppy.
The target would be, just stick the floppy in any old junk PC without a
working HD and it will just boot straight to APRSdos and the regional maps
(there would be one for EAS, WES, MID, CEN, NW etc...)
Remember, once APRSdos boots and loads the 3 most recently used maps to
RAM, it never needs the drive so it is not slowed by A: drive... but you
can zoom anywhere (and if it needs another map, it will bring in a new one
(from A drive) and overwrite the least used of the other three in
memory)...
So generally it just runs and is available there on a PC in the corner for
continuous local use... not tying up your MAIN PC and NOT HAVING YOUR
$1000 PC tied to your lightening vulernable radio and Antenna. I am on my
3rd blown PC (from lightening) but then Its only a 486 from the junk
pile...
Problem is I have been thorugh so many laptops since I last released
APRSdos that I cannot find the latest source. Best I can find is APRS850.
And all my current source for APRS with all the Kenwood radio controls and
satellite tracking and auto-rig tuning is just not working. Its totally
hosed...
Is this bootable floppy version worth doing?
Bob
