Fldigi is a modem program for most of the digital modes used by radio amateurs today: CW, PSK, MFSK, RTTY, Hell, DominoEX, Olivia, and Throb are all supported. It can help calibrate a sound card to a time signal and do frequency measurement tests. NOTICE: You must proceed to the Files section to locate the correct fldigi, flrig etal download for your particular operating system. Do not blithely use the big green Download button!

Designed for finding HD FM stations in the US because they have about twice normal width, you can customize it for other frequency ranges. Uses Gnuplot to plot to a .png file.

...Programs are present to demodulate AM, CW, FM and SSB (USB, LSB) streams. Also included is a program that writes FCDPP sample data to its standard output (stdout) port. The programs require the qthid program to control the FCDPP frequency and gain (also available at sourceforge.net. Search for: qthid). Recent activity (10/2014): Added test programs used to construct fun2ssb. See README4; (12/2014) Made program changes to accommodate subsequent complier revisions. For instructions on building qthid-4.1 for Ubuntu 14.04, see a topic under the Discussion menu.

Qthid is a simple controller application for the Funcube Dongle Pro and Pro+ software defined radio receivers. It is written using the Qt SDK and is available for Linux, Windows and Mac OS X.

The AEG Telecar 9, equivalent to the BBC RT-61 radio can be used for amateur radio purposes. The "tc9" projet is an open source alternative to the manufacturer's firmware which is much more "ham" friendly.

Ceasar is an open-source multi-frequency tone gereator for UNIX, initially Linux. By default it contains standard DTMF tones together with C5 (bluebox) tones.

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.

popz is a java implementation of the osi layers one and two over normal phone connections using frequency modulation techniques. This is really useful if you have to check your mail from the himalaya and have only your laptop and a mobile phone with you

minihuff is a data compression library that enables the creation of a static frequency table to be stored at both ends of a connection. This allows effective compression even for very small pieces of data that maintain similar entropy characteristics.
