NOTES ON IMPEDANCE MATCHER:

1.  All files are necessary for proper operation.

2.  A batch file E.BAT is used to load the proper sequence of files

3.  A printed version of the help screen is useful when starting
    to use this program.

4.  This is an automated version of the "back to back" Smith
    chart commonly used for impedance matching.

5.  GENERAL INSTRUCTIONS:

Enter the  system characteristic impedance, as well as impedance
to be matched, when prompted.

The impedance will appear as a yellow circle.  Locii of constant
resistance appear in green, and locii of constant conductance
appear in yellow.

Series reactance may be added by choosing the select reactance
function key, F5.  This leaves the command mode where the
variable is chosen, and enters the move mode with reactance
selected as the parameter to be changed.

Reactance may be added with either F3, (Coarse 20% steps) or F1,
(Fine 2% steps). Reactance may be subtracted with either F4,
(Coarse 20% steps) or F2, (Fine 2% steps).

To return to the command mode, use F10.

In the command mode, the following functions may be chosen:

F5     Select reactance

F6     Select susceptance

F7     Select series transmission line

F8     Redo the plot, retaining the original data

F9     Redo the plot, prompting for new data

Alt F9 Display table of Data you entered.  Data will be in the
       form of X1,B2,X3,A4, ..., assuming you entered X first, B
       second, X third, and a transmission line of impedance Z0
       and length A in degrees.
