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.

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 modeled as a voltage controlled switch, or linear where each transistor is modeled 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 modeled environment to see how they will behave without having to touch a soldering iron, or solder.
You can obtain version 2g6 of Spice from:

svgafft is a spectrum analyser for Linux.
Alpha software, but usable.
Linux supported sound card, svgalib, a 486DX33 or better.
svgafft uses the /dev/dsp
device and currently supports 16-bit
and 8-bit sample resolution on supported Linux soundcards. It's display is
something akin to a high-end spectrum analyzer with falling peaks.
Look for svgafft-0.2.tar.gz
on sunsite.unc.edu
Unknown, check any README
supplied.
