Various reference programs to read baseband I/Q sample data from a Funcube Dongle Pro+ (FCDPP) software defined radio (SDR) hardware front end, demodulate the data stream and send it to the host's audio output port. 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.

Pyst consists of a set of interfaces and libraries to allow programming of Asterisk from python. The library currently supports AGI, AMI, and the parsing of Asterisk configuration files. The library also includes debugging facilities for AGI. 2014-04-17: Moved the version control to GIT. To check out see the tab "Code". Note that the whole history including ancient CVS, then some time in monotone, then subversion was united into one GIT repository thanks to ESR's reposurgeon. 2013-05-29: Maintainers of github fork "pyst2" contacted to join forces. Note that the last release here fixes the same bug as on github, otherwise github version seems to only contain cosmetic changes and examples. 2012-07-06: An offer to maintain the project has been received. 2012-01-29: There have been two or three forks that are being maintained. This is now just history unless someone cares to take up maintenance here.
