elbug - simple c program for electronic morse key at the serial port
a simple c program for an serial elbug = electronic morse key.which is to be plugged to the serial port, its output is also a pin in the serial port.
Just compile it by 'gcc elbug.c -o elbug'
or use the ready-compiled file and copy elbug to user/local/bin.
/* Call it as root. */

OpenPoc is a Cross-Platform POCSAG-Decoder written in FreePascal/Lazarus. A Radioscanner/-receiver and a Soundcard are needed to decode POCSAG-Transmissions.
Please respect the law in your country concerning the capturing of radio-transmissions.
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.
Dsctl is a CLI program for controlling as many aspects of the Uniden Bearcat BCD396T and BCD996T radio scanners as possible. This includes backup and restore of memory contents, scanning, searching and trunk scanning. (This is a branch of Sctl.)
A modular C-language library, which parses (regex) radioamateur HAM callsign and prints its country or world region : F4ECW=France, LX2CR=Luxembourg, 4JAA=Azerbaidjan, TU5EX=Ivory Coast... Comes with a command-line interface. Useful for APRS.
The aim of "FT100 Rig Control " is to provide GPL software to control a Yaesu FT100 Amateur Transceiver.
The initial focus of the project will be to provide a simple commandline interface, followed by a graphical
interface.
This project is aimed primarily at users of the Icom R20 Communications Receiver and it's predecessors (R3, R5, R10). The intent is to provide ability to extend the capabilities of the radio, and provide an API to programmers interested in it.
