Hi martin
Success the calculations you gave made sense and ive now got my head around how to derive the frequencys i want but now realise the period is critical when choosing duty
Thanks for the help and giving me the insight to playing with the pwm function

Yes, that it why I showed the period as part of the duty calculations.
If the period is change then the Duty value must be updated to give the same %.
