An Introduction to APRS And 'APRS for Newbies' by Arte Booten - N2ZRC

An online discussion board for APRS from KD4RDB

From Richard Hoskin (VK3JFK), an excellent article: APRS New User Guide & Path Information.
Should be 'required' reading for all new to APRS

Bob Bruninga's site the one who started it all

This is THE Site for software, maps and info for the Windows or Macintosh system

More maps are available from TAPR

"A Very Questionable Page Indeed" - howerver a good source for APRS info!

This section wouldn't be complete without listing TAPR's offerings

APRS and LINUX
XASTIR

*THE* LINUX APRS client software: Xastir: Xastir provides graphic mapping (*many* map formats), I-gate services, Messaging, Weather shapes, Gating of weather information, etc. Truely a full featured APRS client. Will use LINUX's native kernel AX.25 support or serial TNC access.

For those on the bleeding edge, use the CVS server at argon.hscs.virginia.edu for the latest xastir and aprsd source code.

To obtain xastir over CVS, do as follows:
(1) log into your shell
(2) type 'export CVSROOT=:pserver:anonymous@argon.hscs.virginia.edu:/usr/local/cvs'
(3) type 'cvs login'
(4) type 'xastir' when it asks for a password.
(5) in your home dir, type 'cvs checkout xastir'
(6) in ~/xastir, you should have a copy of the latest CVS version of xastir.

Then read the README file in ~/xastir for instructions on compiling, setup and use

For the aprsd source: Follow the above instructions, except while in your home directory use 'cvs checkout aprsd'. The aprsd source will then be in ~/aprsd

APRSD

For a dedicated APRS server/I-gate, look at WA4DSY's APRSD (origional site).
It's been Sourceforged as well! (Most recent flavor?): Very configurable dedicated I-gate and APRS server, runs as either a daemon or program. Be aware of what each of these 'flavors' of aprsd will do, even though they're all 'aprsd 2.1.4' they are different versions. The aprsd on the origional site is serial only. The SourceForge version is both LINUX kernel AX.25 and serial enabled (though there's question of the functionality of the AX.25 access - 20 June). The VK3SB version is kernel AX.25 enabled only. These differences are subject to change. Read their documentation! RTFM is *not* a four letter word.

XASTIR

FWIW and IMO, "Xaprs" is still born. Compared to xastir, Xaprs verges on being a waste of effort. To this date, other than the developers, I've yet to find *anyone* who's ever used Xaprs. Kudos to the the Bros for giving it a shot, they've done wonders with WinAPRS, if you're using a GUI'd OS from "Billy's" outfit, then WinAPRS is one of the first you should be using. Leave Xaprs alone - everyone, the energy will be much better spent elsewhere

If you insist on playing with Xaprs, it can be found on the Rutgers Site

Wyoming and local Area Information Suggested Wyo APRS Path: RELAY,WIDE or RELAY,WIDE2-2

Please, avoid using multiple WIDE's in your paths
Use 'WIDEn-n' instead. For most, WIDE2-2, does quite nicely

Using multiple WIDE's (ie. WIDE,WIDE,WIDE), will create a 'packet ping-pong' as the digi's clutter the chanel with excesive digipeats. Many of the digis in SE Wyoming won't respond to a WIDE. WIDEn-n digi's checks for packet duplication before digipeating, therby greatly increasing the RF network's usefulness. This is the suggested setup for any new digi's as well.

Pick a city below for local information relavant to that area. Updates and corrections are MOST welcome! Please, either submit them via the Rocky Mnt APRS reflector (above) or direct via the email link below
