A "simple" demonstration software for decoding ACARS, a low-bandwidth communication protocol used by airplanes to communicate with airports. Detailed description of the operating principles is available at http://jmfriedt.free.fr/lm_sdr.pdf (French) and http://jmfriedt.free.fr/en_sdr.pdf (English). The latest 2022 release for GNU Radio 3.9 and 3,10, following 3.8 named ng for New Generation, aims at adding bitrate clock tracking + removes the external dependence with libfftw by using the GNU Radio FFT wrapper. ...

A graphical (Gnome) based Morse code decoder capable of decoding Morse code from audio that is captured via a sound card device.

...It features : - up to four channels decoded simultaneously - error detection AND correction - input from sound file , alsa sound card or software defined radio (SRD) via a rtl dongle (http://sdr.osmocom.org/trac/wiki/rtl-sdr) or airspy (http://www.airspy.com) - could send decoded acars to a server via UDP in planeploter format or its own dedicated format. The 4 channels decoding is particularly useful with the rtl dongle. It allows to directly listen simultaneously to 4 different frequencies , with a very low cost hardware. Since version 3.0, acarsdec comes with acarsserv : a database backend program to store received acars messages.

RDS Surveyor is an RDS/RBDS decoding, monitoring and analysis tool and library. It has migrated to GitHub: https://github.com/ChristopheJacquet/RdsSurveyor/

This ASN.1 compiler turns ASN.1 specifications into C code. The asn1c is shipped together with conformant BER/DER/XER/PER codecs. The X.509, GSM TAP3, MEGACO, RRC and LDAP encoding and decoding examples are part of the source code distribution. NOTE: THE asn1c PROJECT HAS LARGELY MOVED TO GITHUB: http://github.com/vlm/asn1c

GNU AIS is software for demodulating and decoding Automatic Identification System messages used by ships to navigate. You will need a VHF receiver with discriminator output to get it to work.

Morse Code (CW) decoder for Unix-like systems (and Windows).

Tools for encoding and decoding amateur radio callsigns, up to 2x4 & 185 nodes, from IPv6 /64 subnets with Universal bit support and Amateur Radio Flag at the 24bit. Experimental RFC to IETF is being submitted for this proposed amateur standard.

A stand-alone or plug-in application that supports automatic decompression/decoding of files (.tar, .gz, .shar, etc.).

Decoding the (german) DCF77 time signal per USB sound card and a receiver module, setting the system time. "U" stands for USB and "77,5" for the full 77.5 kHz frequency of the time signal.

A C callback orientated parser library for card (vCard/vCal) objects, reentrant & stream orientated, handles line folding, automatic decoding of params and data

Powerful encoder/decoder for the newly popular Usenet yEnc file format. Features include easy configuration, internationalization, memory efficiency, and an intelligent decoder capable of finding and decoding input files, including out-of-order files.

We at GCD are here to bring you ease in decoding your friends CRYPTIC GeekCode .signature files -=). Also sometime in the future we plan to eventualy start an ENCODER to help you even more!
