DXSpider is a Ham Radio program that connects to other similar programs by radio or the internet and provides a real-time information service to Ham Radio operators rather like IRC. It is designed to become a complete replacement for the original DOS implementation written by Dick Newell AK1A.
CWBot is an IRC bot to provide online services in Morse usable with the CWirc client. It can broadcast world news in Morse and Hellschreiber, RAC ham news, act as a MorseMail to CWirc repeater, be a CW tutor, or send fortune cookies in Morse, over an IRC channel or through DCC chat, with adjustable keying speed and Farnsworth spacing. It is easily extendable with scripts or external programs to provide additional services in Morse.
PicoStreamer is a complete server for live audio/video streaming. It can stream MP3, AAC, and video live using Flash FLV. It does not require any Flash server. It only needs a Web server with Perl and PHP. It requires neither expensive dedicated servers nor compilation on the target machine. A source client (for Win32) is included. A management/playing framework written in PHP makes PicoStreamer simple to use. The PicoIcy component acts as a local shoutcast server emulator, so you can use your preferred shoutcast source client to stream or stream Flash format directly from the Web.
The FAAC project includes the AAC encoder FAAC and decoder FAAD2. It supports several MPEG-4 object types (LC, Main, LTP, HE AAC, PS) and file formats (ADTS AAC, raw AAC, MP4), multichannel and gapless en/decoding as well as MP4 metadata tags. The codecs are compatible with standard-compliant audio applications using one or more of these profiles.
Salut is a small program that performs calculations on simple networks around two-port devices (like transistors) characterized by s-parameters, at radio frequencies (RF). It has the ability to model components in series with a two-port block, like an inductance from the common lead to ground. Salut is also not restricted to the usual common emitter or common source configuration even though many semiconductor manufacturers only provide s-parameters for this case.
Open5066 is an implementation of the NATO NC3A STANAG 5066 protocol stack for HF radio communications. It aims to implement all of SIS (Annex A), DTS (Annex C), and some of the application layer (Annex F) functionality such as HMTP. The concrete embodiment of Open5066 is the s5066d daemon.
ebook2cw is a command line program that converts a plain text file (like an eBook) to Morse code (CW) MP3 or OGG files. Morse parameters like speed and tone frequency, and audio parameters such as bit rate, sample rate, and quality can be changed by command line switches. It automatically splits and numbers the output files by chapters.
