chattervox - 📡 An AX

An AX.25 packet radio chat protocol with support for digital signatures and binary compression. Like IRC over radio waves 📡. Chattervox implements a minimal packet radio protocol on top of AX.25 that can be used with a terminal node controller (TNC) like Direwolf to transmit and receive digitally signed messages using audio frequency shift keying modulation (AFSK). In the United States, it's illegal to broadcast encrypted messages on amateur radio frequencies. Chattervox respects this law, while using elliptic curve cryptography and digital signatures to protect against message spoofing.

Community Status Reporter

The Community Status Reporter is emergency status reporting software intended to be used to support the Emergency Status Plan currently being developed by the Home Unit volunteers of the Radio Amateur Civil Emergency Service (RACES) in Pima County Arizona.

Gpredict - Satellite Tracking Application

Gpredict is a real time satellite tracking and orbit prediction program for the Linux desktop. It uses the SGP4/SDP4 propagation algorithms together with NORAD two-line element sets (TLE).

aprs - Python APRS Module

aprs is a Python Module that supports connecting to APRS Interfaces, and receiving, parsing and sending APRS Frames. The following example connects to APRS-IS as W2GMD (me!) and filters for APRS frames coming from my prefix (W2GMD, W2GMD-n, etc). Any frames returned are sent to my callback p and printed.

kiss - A pure-Python implementation of the KISS Protocol for communicating with serial TNC devices for use with Amateur Radio

kiss is a Python Module that implementations the KISS Protocol for communicating with KISS-enabled devices (such as Serial or TCP TNCs). See also: examples/ directory.

aprsd - APRS daemon for Polaric Server

The "Polaric Server" is mainly a web based service to present APRS tracking information on maps and where the information is updated in real-time. It is originally targeted for use by radio amateurs in voluntary search and rescue service in Norway. It consists of a web application and a server program (APRS daemon). The APRS daemon gets data from a TNC or APRS-IS or a combination. It can present and manipulate the information through a simple HTTP service. The daemon can also be set up as an igate (internet gateway) and can be installed and run independently of the web app. It has its own webserver.

jdigi - A simple experiment in javascript digital signal processing

A simple experiment in javascript digital signal processing. HTML5's Web Audio API is a wonderful opportunity for people interested in DSP to experiment in audio modulation and demodulation. It's also a great way to provide radio digital mode codecs to users without the need to port code or install binaries. This project in an experiment in doing just that. The project is only a few days old, so currently there is only a waterfall and buggy BPSK31 reception. RTTY code has been added, but it has not been debugged or tested yet.
