FYI:

1. I just requested a current PBP manual to see if the HWPWM feature now includes >32767Hz.
2. I have the PIC12F1572 data sheet which seems to have a completely differenct PWM operation than the 16F628.
3. I did try and test your suggestions for the 16F628 which worked except for the symetrical issue.

Below is the App so far with Zero progress on the PWM.
All it will do is modulate an 125KHz magnetic antenna using OOK.

Currently, I have configured the internal OSC for 16MHz.
I do not know whether the 4X PLL is required for a perfectly symetrical On/Off Duty Cycle of 4uS On / 4uS Off.

Peace,
