I use the RTCC (TMR) for frequency counter duty.  You can change the
prescale, and shift the main oscillator freq externally under command of the
PIC to give more flexibility.  Multiple counts and averaging gives more
stable results.

You can use the RTCC to determine duty cycle by comparing count and overflow
times once frequency  is narrowed in on.

Lookup table is the quickest way to handle divides.  You can have multiple
tables on multiple top halves of memory pages.


.... or just use an LO and a mixer/bandpass... but that wouldn't be as
fun!!!!!!!!!
