**UPDATED* Schematic of High Efficiency Class H Modulator

[blaine]

I have completely redone the class H modulator. It is the same in concept, but the new version has MANY new features !!!!

Regulated (and adjustable) carrier DC level
Interface to the fast overload shutdown / efficiency meter circuitry
More components on the PC board for easier construction
Correction to the high frequency distortion problem (note: this was not a big problem - no one has ever heard it except me).
PC Board implementation - boards are available (kit of parts SOON)

Check out The class H modulator section of the class E web site
