APRS for HF as well as VHF position reporting - adjuvantjfoster - April 30, 2007
With all the buzz about VHF AIS receivers, there is also a mature, longer range HF as well as VHF, technology for position recording, the Ham radio APRS.
APRS is an abbreviation for Automatic Packet Reporting System, and it is a graphical method of broadcasting positioning information in "real time" from packet radio-equipped stations. It was originally designed by Bob Bruninga WB4APR in the early 90's, but it has seen explosive growth in the last few years due to excellent software for Mac Linux and Windows.
For a primer about APRS look at
http://www.arrl.org/search/?exp=1&q=aprs&x=10&y=12
My question is this: Anybody out there using MacENC have any interest in adding APRS capability to MacENC to extend the range of AIS position reporting?
Look at a site such as http://machamradio.com/HamsAndX.html , (where I wish Mac ENC was listed) for some choices of APRS software. Look at Paketograph, a universal binary, for example
Let us read if you think it should be included in Mac ENC, or if Mac ENC should be simply linked to an existing Mac OS X APRS package.

X Amateur Tracking and Information System
Xastir is program for receiving and plotting APRS™ position packets. Development is a collaborative effort of programmers and amateur radio enthusiasts from around the world. Xastir supports many map formats and is highly customizable. Check out the "Screen Shots" link to see just a few of the ways that Xastir can be used.
Xastir runs on Windows/MacOSX/Linux/FreeBSD/Solaris/Lindows, with many more possible. It supports 125 map formats, several types of TNC's and weather stations, Festival speech synthesizer, AX.25 networking (Soundmodem/Baycom/SCC!) and seven languages!. On Unix-like operating systems, you can run your weather station or global positioning system (GPS) on a separate computer as well, which is good for those hams who are already short on serial ports.
Xastir is FREE! under the GPL license and comes with all source code.
