xcw is a small utility to input text with a morse key in any X11 program. xcw reads morse from a straight or iambic key connected to a serial port, decodes it, then sends the decoded text to the X window currently in focus. The morse code sound is played through the sound card.
xdx is a GTK+ 2.0 DX-cluster client for amateur radio operators.
Xlog will display a log with the most recent contacts added to the top. You can add, delete and edit log entries. The log is saved into a text file. You can open, close and create logs as you need them. Xlog supports cabrillo, ADIF, trlog (format also used by tlf), and EDI (ARRL VHF/UHF contest format) and can import twlog, editest and OH1AA logbook files.
xtalfind checks whether any XTAL is suitable for a HAM radio circuit.
