Is there some place I can find info about the different version of APRS. I
have looked but cannot find any info.
Thanks

This might help:

Click on the link on the left which says "APRS Client Capabilities
Chart".
If anyone has any updates to that chart, please send them my way.

Ok, next question... anyone got a sample dump from one? I haven't touched a
LORAN-C receiver in about 10 years.

Is there someplace I can look for some sample packets that are KNOWN to be
valid for APRS.
Yes, I know, read the spec. But I want to actually see some packets so
that I can make sure that when I write my packets, I know what is an
acceptable packet for comparison.

Wonder if any one has seen a HF/VHF/UHF transceiver which is computer
programmable has 200+ memories, scan VHF & UHF with PL/DPL, and of course
can be connected to a TNC for APRS. In other words a D700 with HF. The
radios I've seen lack scan, memory and computer programmable. Tnx.

Hi ya'll!
I am attempting to get many Western USA APRS stations to send a few beacons
on Tuesday, Jan 13th.
I need each of you to send 3 to 5 posits to an UNPROTO address of :
APRS via KE6QMD
between 19:41 UTC and 19:48 UTC on the frequency of 145.945 mhz.
I'd like to see dozens of stations from Washinton, Oregon, California,
Nevada and Arizona...and maybe Texas if possible.
Your help will greatly be appreciated. And, if you have the time, please
email me and let me know you've done this!
Thank you If this works, I'll post results!

Subject: New serial port software gizmo to map serial ports over TCP/IP
From: "Stephen H. Smith" <WA8LMF2@aol.com>

I have been using a virtual serial port driver made by Eltima Software
for a year now to connect MixW acting as a sound card software TNC to
various APRS apps that expect a hardware TNC attached to a serial port.
The VSPD (virtual serial port driver) emulates a pair of serial ports
cross-connected (i.e. null-modem cable). You then configure the serial
port settings of one program to use one of the fake ports and set the
other program to use the other. I have used this to connect the output
of SailSoft's GPS emulator to the input of an APRS program or moving map
app (i.e. Street Atlas, MapPoint,etc) running on the same computer. I
have also used the VSPD to connect two APRS programs back to back (on
the same computer) to test how one program interprets packets sent by
the other without having to setup two computers, two TNCs and two radios
(You set both apps to use a KISS TNC to avoid the issue of what kind
of TNC to set the programs to when there aren't any.)
A freeware version of this gizmo is available on the MiwW website (look
for the "Mix Serial Port Bridge") but it only works with Windows 2000
and XP. The version from Eltima also works on Win95 and 98.
I just received the product bulletin pasted below from Eltima -- they
have now extended the capability of the driver to simulate two serial
ports connected back-to-back over IP networks (either private or the
Internet), rather than just two serial ports in the same machine.
This could have some interesting APRS uses such as having a soundcard
software TNC running in one PC at a good RF location feeding an APRS app
running on another machine almost anywhere else. [ Of course, AGW
Packet Engine already produces direct TCP/IP output from a soundcard
modem; this would allow apps that only know/support serial ports to do
the same. ]
========== PASTE =============
Dear Customer,
I couldn't help telling you about the new virtual serial communication
solution by Eltima Software. I'm talking about VSPD.net. This is the
product we worked on for about half a year, and hope it will become
useful and helpful in your everyday work.
Network Virtual Serial Port Driver (VSPD.net) is an advanced utility,
the purpose of which is to emulate null-modem cable on computers located
in a TCP/IP LAN or connected to the Internet. In other words, with
VSPD.net you can create any number of pure virtual serial ports in your
system, which will be connected over TCP/IP network to another computer
via virtual null-modem cable. Real serial ports will not be occupied.
For instance:
You have two computers, host1 and host2 for example, connected with
TCP/IP networking. You can create COM5 on host1 and COM6 on host2 and
connect those ports to each other via virtual null-modem cable.
Everything, that application on host1 will send to COM5 will be received
by application on host2 at COM6, and all that application on host2 sends
to COM6 will be received by application on host1 at COM5.
Additionally, here are a few links to provide you with the information
about the new product:
http://www.eltima.com/products/vspdnet/ - VSPD.net temporary homepage,
we will also post it on www.virtualserialport.com very soon.
http://www.eltima.com/download/vspdnet/ - Free download of VSPD.net
trial version.
http://www.eltima.com/forum - you are welcome to ask any questions in
our Forums. This is really the ultimate place to communicate and discuss
our new and current projects and products!
In hope for a profitable cooperation...

Typically they used the $LCGLL and $LCVTG sentences (format identical to
$GPGLL and $GPVTG...

Extracted from http://vancouver-webpages.com/peter/nmeafaq.txt ....
The data is transmitted in the form of "sentences". Each
sentence starts with a "$", a two letter "talker ID", a three
letter "sentence ID", followed by a number of data fields
separated by commas, and terminated by an optional checksum, and
a carriage return/line feed. A sentence may contain up to 82
characters including the "$" and CR/LF.
I'd ignore the "talker ID" and just decode the "sentence ID".
Have a look at the whole web page... Good stuff!
