Projects in development!
Build an APRS-compatible weather station that doesn't need a TNC to transmit! The new µWeatherTM (pronounced Micro Weather) project kits are now available.
Speak APRS with the CybikoTM hand-held "kid's PDA", with KR1ST's UI frame client. Check the link for an inexpensive KISS TNC (with GPS input) to put it on the air.
VE4KLM is working on an APRS IGate server for NOS; visit his TNOSaprs/JNOSaprs - APRS Server page for more information.
Visit the Amateur Radio on the International Space Station home page!
NIAN APRS Discussion - replacement for the old "building your APRS network" page that was never updated. An easy-to-use way to find APRS information and discuss it with people who know what's going on.
Setting up a KPC-3 Plus or KAM 98 with version 8.3 software as a dual-mode tracker for APRS.
Setting up a KPC-3 or KPC-3 Plus with version 8.2 software as a DIGIPEATER for APRS, or any Kantronics TNC as a STAND-ALONE TRACKER with version 6.0 or later software.
Using a PicoPacket as a dual-mode tracker for APRS.
Looking for less in the way of a tracker? Check out the Byonics TinyTrak as a minimal tracker... Or step up with a HamHud II display module for APRS. (Note: TinyTrak replaces the TNC; HamHud gives you a simplified mobile display for your existing TNC-based tracker).
Want to build an inexpensive TNC that can be expanded? That's what the TNC-X by Coastal Chipworks is all about. Options include a digipeater and tracker daughter board.

Not quite so NEW anymore: Building a digipeater inside an old computer... or make your APRS computer a more integrated affair!
Alan N2YGK's APRS digipeater software for Linux has been updated to include such things as being able to link digipeaters across vast distances using TCP/IP. More information is available in the tarball.
Have a TNC-2 or clone? UIDIGI is software from Italy that will allow much of the "ideal" features of an APRS-specific digi be put into a readily-available TNC.
