Default Choke Baluns again. New program


NOW AVAILABLE ** New Program "BALCHOKE.exe"

This program is very similar to program CHOKEBAL The main change is to
input data. The ferrite core is rectangular in shape and defined in terms of
thickness and length instead of a circular core diameter. The size of the
core is described more conveniently in terms of the outside diameter of the
ferrite ring instead of the diameter of the mean magnetic path.

The opportunity has been taken to provide, in the author's opinion, a better
statistical way of estimating percent current unbalance in the twin-wire
transmission line. There are also better program operating notes.

Although most numerical results are identical this second version of the
program is recommended.

Program size about 36 kilobytes. Download program BALCHOKE from website
below in a few seconds and run immediately from a desktop icon.
