RWTH Amateurfunkgruppe

APRS English version

Since 2007 there is an APRS Digipeater running at DB0SDA. This is a automatic working radio station which receives position reports and messages from other amateur radio operators and re-sends them amplified. Due to this flood-fill behavior reports get spreaded all over the world. Besides there is a two-way internet connection to a central server. Using maping services like www.db0anf.de or aprs.fi the position of amateur radio stations can be displayed user-friendly on a map. The status page of our APRS-Server can be accessed at http://www.afu.rwth-aachen.de:14501.

To send and receive APRS messages via a TCP connection the server is listening on port 14580 at www.afu.rwth-aachen.de and via HAMNET on db0sda.ampr.org . Authetification with the amateur radio callsign und a validation number is mandatory. The classical APRS-Filters can be set, too. A common windows application is UI-View32. We provide some maps for the surroundings of the city of Aachen. After downloading, you have to copy the extracted files into the MAPS directory of UIView.
