Software to assist in the design and construction of amateur radio related things. Antenna, Circuit Board, Filter, and QSL card design packages are all good candidates for this section.

Scope is a simple software emulation of an oscilloscope. It graphically displays voltage as a function of time.
ALPHA. First release.
Sound card with input capability supported by the kernel sound driver. SVGALIB is used to do the display work.
Scope uses the /dev/dsp device to take audio in from the
soundcard and displays it on the screen in a manner similar to an oscilloscope.
Jeff claims Scope was written more for amusement value than for any serious
purpose.
You can obtain source, makefile and man page for Scope from: sunsite.unc.edu

An event-driven logic-level simulator for MOS circuits
Version 8.6, production.
X-Windows.
irsim is an X11 based simulator for MOS circuits. It has two simulation modes, either switch where each transistor is modelled as a voltage controlled switch, or linear where each transistor is modelled as a resistor in series with a voltage controlled switch, and each node has a capacitance.

Spice is an analog circuit emulator.
Stable release. Last fortran version produced.
Unknown.
Spice allows you to design and test circuits in a computer modelled environment to see how they will behave without having to touch a soldering iron, or solder.
