I discovered the spectrum of the PWM wave was strange.
I used the Fast PWM mode, 31kHz and a sinewave 600Hz modulation
frequency, sampled 8 to 32 times per cycle. IOW, I changed the PWM
pulse width 8 to 32 times per cycle of the modulation sine wave. The
modulation sine wave sampling rate seemed to make little difference in
the FFT of the output as displayed on a TDS 2014.
I can post the code and FFT, if anyone is interested.
