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 X11 based interactive printed circuit board design tool.
Vers 1.3, stable.
X11 Windowing system and a recent flex program.
The pcb package comes with good instructions on how to compile and install the software. I compiled it without error under X11R6. It comes with package layouts for a range of popular components and the example layout nicely demonstrates the capabilities of the package.
You can obtain the pcb package from: sunsite.unc.edu or from: ftp.medizin.uni-ulm.de

Schematic Entry and Digital or Analog Simulation.
vers 5.10, stable.
X11 windowing system and older (XFree86-2.x) libs, 8 bpp (256 color) only
I haven't tried this one out yet.
You can obtain the Chipmunk package from: sunsite.unc.edu or ifi.uio.no .

An event-driven logic-level simulator for MOS circuits
Version 9.2, 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.
You can obtain irsim from: sunsite.unc.edu .

Spice is an analog circuit emulator.
Stable release.
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. A readme
file comes with the package. To install I
did the following:
# cd /usr/src
# gzip -dc spice3f4.tar.gz | tar xvf -
# cd spice3f4
# ./utils/build linux
# ./utils/build linux install
You can obtain version 3f4 of Spice from: sunsite.unc.edu

svgafft is a spectrum analyser for Linux.
Alpha software, but usable.
F77, 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.
You can find the software at sunsite.unc.edu .

An audio spectrum analyser for Linux SVGALIB or X-Windows.
Alpha but usable
Linux supported sound card, svgalib or X-Windows.
freq5a1 uses the /dev/dsp
device, samples the incoming
audio, performs a fast fourier transform on the data and displays the
output in either 640x480 VGA or an X-Window.
You can obtain freq5a1.tar.gz from: sunsite.unc.edu or by mail from the author.
