New program OPANGLE3

[Reg Edwards]

NOW AVAILABLE ** New Program "OPANGLE3.exe"

Choose and set plate current operating angle for Class-B and Class-C
RF power amplifiers.

Input data includes control-grid plate-current cut-off volts, DC
negative grid bias, and peak grid drive volts.

Advice on how to use Tube Operating Characteristic Curves is included.
For interest the plate current harmonic content is computed up to the
21st harmonic.

For given DC plate supply volts and peak plate signal volts, the DC
power input, tuned load resistance, RF power output, plate dissipation
and efficiency are computed.

This is a repeat of program Op_Angle (now withdrawn) with the addition
of an analysis of conditions in the plate circuit.

Program size = 50 kilo-bytes.
