Default Re: FM to AM converter - variation on a theme!

Where are you sampling the sine wave, David? Is this the unmodulated RF output from the modulator? I don’t think it’s crossover distortion, which normally appears symmetrically on both rising and falling edges of the waveform. It also looks as if the slope of the rising edge is less steep than the falling edge, signifying considerable distortion.
