New Program - OP_ANGLE.exe

This program assists with understanding, choosing and setting the
operating angles of Class-B and Class-C RF power amplifiers.

The operating angle underlies all performance characteristics.

Although RF operating conditions for tubes can be set up using
manufacturers' data sheets, the program refers to use of a tube's
Operating Characteristic Curves.

Hi Reg,

Thanks for your program. Can you or anyone else point me to a
reference that comprehensively and authoritatively lists the
characteristics of the different transmitter classes (class AB, C , D,
etc.). I have references that give partial lists, and are not in
agreement.

Thanks. My 2005 copy has a list that's probably identical, which
glosses over classes D-H (and there are probably more now). Any other
references out there?

I would classify as follows -

Class A: Operating angle = 360 degrees.
Class AB: Operating angle = 180-200 degrees.
Class B: Operating angle = 180 degrees.
Class C: Operating angle = less than 180 degrees but usually between
150 and 110 degrees.

I don't know about the others but they are probably not defined by
operating angles.
