PowerSmith©™ The Electronic Smith Chart, /simulator/s-parameters/..
"In RF there are no real values, only complex values"

PowerSmith is program for impedance matching. Written by David Tomanek VA3DIW and Martin Kratoska OK1RR. It is a modeling and simulator tool. Use of the program is from discretes to antennas.

The OS System
Try VMware for multiple OS platforms. It can switch over to different OS within seconds.
Point of interest may be the gentoo Linux, Ubuntu Linux, Lynx, Fedora Linux, Slackware Linux, PCLinuxOS, LinuxMint, worth to mention minix3. It will take time to reinvent UNIX. Stable system is an OPEN OS with accessible source code, where everybody can contribute and debug.

For the User
We have tried to do something for small companies and hobbyist.
The non-profit users are encouraged to use the software. The profit-oriented entities are encouraged to support further development. The software was written during winter 2000 in Winterpeg MB (-40°C outside). Global warming is for nuts. During the next arctic winter, a graphical user interface was added. There are over 42,000 lines. Several thousands of hours were invested from free time. There is no component limit, the favourite commercial 10 component limit.. Use whatever number of components you want. Memory is the limit. A significant number of people were interested in copying the source code for commercial activities, without any support. Porting to C++ Microsoft crap. Learn C. "C" is fully documented to the registry level. C++ is not.
Runs smooth on WinXP, FAT32. The NTFS file system is not supported.

How it works
You can download without license keys, without extracting your own private information, without suddenly expired licenses, or hidden fees.
Everything depends on you. Now - you are the investor.

VA3DIW

Well, well before 2006 started "The Technology Theft Campaign" in Canada and USA
with the trademark "Copied in China 2025". Canadian and US companies were full of
the "chinese traders". The interest was in mmics, microwaves, SiGe, GaAs, IBM.. you name it.
At least somebody opened eyes to many naive folks.
