This article describes a method for integrating Foursquare check-ins with Automatic Packet Reporting System (APRS) position reports. Using this integration, a licensed Amateur Radio operator can have location check-ins on Foursquare automatically transmitted to the world-wide APRS network. The software and endpoints for this integration are written using Python.


Foursquare is a location-based social network that allows check-ins at venues or locations using a mobile device (ie Phone, Tablet, Web). These check-ins note the coordinates of the associated location or venue.

APRS is a packet-based reporting system used by Amateur Radio operators world-wide. Typically report packets are transmitted over Amateur Radio frequencies (such as 144.39MHz in North America). However, the APRS Internet System (APRS-IS) allows packets to be transmitted and received over the internet, creating a gateway between radio and the internet.
