2018: Transmission line Calculator tlc.htm/tlc-e.htm
My latest project dealt with simulation of RF circuits, where I developed a
closed formula for computing the values of the the short
conneting wires between connectors, components, pc boards and the like for the
Equivalent Circuit Diagram.
Simultaneously I found a formula for calculation of the characteristic impedance of
a round center conductor in a square outer conductor, which is of high accuracy.
Details can be found in a separate folder www.qsl.net/dh2mic/tlc/, if you click here.
2004: My first project in English was a DOS Configuration Software for configuring the nice and
tiny APRS-Tracker TinyTrak
designed by N6BG, Byon Garrabrant. The reason for writing this configuration software for a
simple line based computer without graphics display was, that mobile windows computer
were very rare 15 years ago. That has changed significantly, so it is only of historic
download the program "TTCONFIG.EXE"
V1.0 as a zipped archive (TTCONFG.ZIP 64 kbytes) from here.
As the program TTCONFIG.EXE has some features currently not available with the
TinyTrakConfig.exe program for Win95/98 and contains a huge help section, this help section may be
of interest for non-DOS users as well. They could download the help section
"tinyhelp.txt" in text format or
as "tinyhelp.htm" in hlml format.
Thanks for passing by...
