Or if you really want to do it the quick and easy way use Xastir's
Coordinate Calculator. Enter the location once, hit the button, and it
generates all of the lat/lon formats, UTM, and 6-digit Maidenhead grid.
Of course I tried entering it similarly to what you originally had,
changing the dots to spaces, and Xastir gave me a wrong answer (didn't
match the Perl script's answers). It took me a second or two to realize
that the format in the .INF files for lat/long is non-standard. That has
bitten me before, and probably a lot of other people.
The format in there is decimal minutes (DD MM.MM), but it's written in such
a way to make you think it is decimal seconds (DD MM SS). The clue in this
case is that some of the numbers are >= 60.0, but that doesn't always have
to be so. You must know what the format is ahead-of-time 'cuz it's not
obvious from the data. When the Perl script was written, I found out about
this little problem. Since then, I forgot about the non-standard format.
I really wish they'd switch to a space-separated format instead of the
decimal-separated format, and keep to a standard representation of
lat/long. As it is, it's very confusing. We've had enough confusion
regarding various lat/long representations on SAR missions before. I'd
hate to see it cost someone's life! Sometimes seconds really do count, and
the Coordinate Calculator was written to speed up these translation
operations in the field. It sure beats entering a position on a GPS to do
the translating, which we've done before.
I just tweaked Xastir so that if minutes/seconds are negative or >= 60.0 in
the Coordinate Calculator, it feeds back the error text instead of what
might look like a valid answer. That should help in the future. At least
it doesn't hide the problem. The error text looks like this:
** Sorry, your input was not recognized! **
** Please use one of the following input formats: **
** 47.99999N 121.99999W, 47 59.999N 121 59.999W **
** 10T 0574599 5316887, 47 59 59.9N 121 59 59.9W **
And you'll also now get this message in the xterm window you started Xastir
from:

I remember there was an HF APRS SIG that was created. Can someone send me
(off list) that information, please? I think I am a subscriber but I
cannot find the email address or anything associated with it.
Thanks,

APRS users must often convert between the multiude of Lat, Lon formats
found in various application programs and on maps.
There are so many different formats in use today in APRS that it is
difficult for mere mortals to sort them out. Not much easier for
applications to convert them when users have difficulty identifying the
required location elements.
Here are a few lat, lon formats for a single location:
APRS Format : 4134.38N 08803.27W
UiView : 41.34.38N 88.03.27W
WinAprs : 41 34' 23"N 88 03' 16"W
NMEA : 4134.38,N,08803.27,W
GARMIN eTrex : N 4134.381 W08803.271
N 41=B034'23.1" W088=B003'16.1"
PMap : 41ø34'23",-88ø03'16"
41 34.38',-88 2.27'
41.573056ø,-88.054464ø
Not too familiar with UTM. Are there various formats used for this as well?
UTM : 16T 412086E,4602991N

Hopefully someone can help me. I just downloaded and compiled the WA4DSY
Linux APRS server.
The compile and install went very smooth.
With a few tweaks to the 4 config files, I brought it up.. I pointed the
Java Applet at the server and voila, the map started filling up with
stations..
On the TNC side, I have the TNC attached, however I have not fired up the
radio side yet.. I wanted to make sure the traffic flowed properly before I
did that.
After running for a while, I noticed that the igate was not showing on the
map. I went to findu and looked under my call sign and -- nothing..
So it seems the inbound is working, but the outbound is not.
I did run the aprspass program to set the password to the value for my
callsign.. What am I missing.. I have sent the author an email, but as of
yet, no response.
Any thoughts?
Second Question - I'm running this igate because the machine I am running it
on is my IRLP node. I was hoping to use the program udp_example and load the
position for my IRLP node and follow the IVRS speck for the position
record.. That program talks to port 1315.. How would I structure the message
to that port to send out my node's position?
Thanks for any pointers..

People
This is your last chance for papers for the DCC. They need to be in by the
5th of August. And we need as many papers as possible on the broad subject
of digital communications. You can get more information on www.tapr.org/dcc
If you are finding it hard to get the paper finished by the deadline,
contact me and I will see how I can help
Hope to see you there in Connecticut in September

Gents,
Picked up a GARMIN GPS72 for APRS. Seems to do all I want it to do, as well
as put APRS stations on the screen.

The site is still up, it was down a few weeks ago for a server switch over.
But up and going strong now.
