"APRS is not a vehicle tracking system. It is a two-way tactical real-time digital communications system between all assets in a network sharing information about everything going on in the local area. On ham radio, this means if something is happening now, or there is information that could be

Very few hams have portable equipment for APRS but nearly everyone has a handheld radio that can send DTMF tones.  APRStt allows a user, equipped with only DTMF (commonly known as Touch Tone) generation capability, to enter information into the global APRS data network. Earlier implementations required specialized hardware and

Amateur radio repeaters retransmit signals from other stations to increase their range. Analog voice repeaters listen on one frequency and simultaneously retransmit the same signal on a different frequency. APRS digital repeaters (digipeaters) use a “store and forward” approach.  A packet is received, examined, then possibly modified and retransmitted.   Usually

Polaric Server is a powerful and flexible open-source platform designed to handle geographical information systems (GIS) and Automatic Packet Reporting System (APRS) data.  It's particularly well-suited for tasks such as: * Tracking and visualization: It can display real-time location data from various sources, including GPS devices, APRS radios, and

APRS Thursday is a net managed by Michael KC8OWL, held every Thursday with the aim of growing message activity on APRS across the world. Many manufacturers are now including APRS functionality as a standard feature, making APRS more accessible, and hopefully more popular than ever. The APRS Thursday net is

How can a newcomer get started in APRS? A web search produces mostly: * Very specialized such as the configuration of a specific radio. * Outdated information. (e.g. you must buy a legacy 1980s style TNC or references to software apps abandoned decades ago) * Only talks about trackers and aprs.fi.

Club meetings and ham conventions are always looking for speakers. There was nothing about APRS during the 2024 Dayton forums. Suppose you wanted to give an APRS presentation at a club meeting or ham convention. But... It's a big job. You are not sure where to start and

Besides sending “messages” to other people, you can also send messages to many automated APRS Information Services.  I could not find a comprehensive list, so I started my own list.  I would greatly appreciate any additions, corrections, and improvements.  Tell your friends!
