WSJT ("Weak Signal Communication, by K1JT") offers specific digital protocols optimized for meteor scatter, ionospheric scatter, and EME (moonbounce) at VHF/UHF, as well as HF skywave propagation. The program can decode fraction-of-a-second signals reflected from ionized meteor trails and steady signals 10 dB below the audible threshold.

WSPR (pronounced "whisper") stands for "Weak Signal Propagation Reporter." This program is designed for sending and receiving low-power transmissions to test propagation paths on the MF and HF bands. Users with internet access can watch results in real time at WSPRnet.

Allows access to Telldus Tellstick USB dongles for communicating with 433MHz devices in your home. Provides "telldusd", the daemon which keeps track of your tellstick devices. Through a UNIX socket, the sensors and devices can be used/ controlled from the command line tool "tdtool", or via the libtelldus-core C client library.

xnec2c is a GTK+ graphical interactive version of nec2c. It incorporates the nec2c core which it uses for reading input files and calculating output data, but it does not need and indeed does not produce an output file by default. Graphs of frequency-related data and the current or charge distribution evolve as the frequency loop progresses, and radiation patterns (far and near field) are sequentially drawn for each frequency step.

Wy60 can be invoked from within any one of many commonly used terminal emulators as long as there is a working terminfo entry for it. It sets up a emulation environment converting between Wyse 60 escape sequences and the escape codes of the host system, and launches a shell to run within this emulated environment. The current set of supported escape sequences is limited, but should suffice to run many existing legacy applications without requiring any changes.

This program converts the .drg propiatary file format into the open source SBaGen format.

Base64 is a command line utility which encodes/decodes arbitrary binary information in the base64 format used by MIME-encoded documents, such as electronic mail messages with embedded files (RFC 1341 and successors).

These programs convert between textual and binary representations of numbers. ascii2binary reads input consisting of textual representations of numbers separated by whitespace and produces as output the binary equivalents. The type and precision of the binary output is selected using command line flags. binary2ascii reads input consisting of binary numbers and converts them to their textual representation. Command line flags specify the type and size of the binary numbers and provide control over the format of the output. Unsigned integers may be written out in binary, octal, decimal, or hexadecimal. Signed integers may be written out only in binary or decimal. Floating point numbers may be written out only decimal, either in standard or scientific notation. (If you want to examine the binary representation of floating point numbers, just treat the input as a sequence of unsigned characters.) The two programs are useful for generating test data, for inspecting binary files, and for interfacing programs that generate textual output to programs that require binary input and conversely. They can also be useful when it is desired to reformat numbers.

Chmview is a simple program to decompose .chm-file to the components. Originally it was written for MS Windows to work in conjunction with Far filemanager.
