You might try Francesco Morgantini's (IK3OIL) PIC freq counter. It's based
on a 16f84 and he will email you the hex code if you request it. It will
run to approx 45 MHz as is and up to 1.5 GHz with a simple add on prescaler.
He has divide functions built in the program ( divide by 10/32/64) and he
has also include IF offset if you want to use the counter as a freq readout.
I've etched about 40 boards for local hams here and every one that has been
built has worked without fail. Total cost has been in the neighborhood of
$35.00 including the prescaler but excluding enclosure. If you want a copy
of the circuit board layout with prescaler, just email me at ww2742 at
dragonbbs.com. As for accuracy, I just adjusted one today for another local
ham at it was within 200 Hz at 440 MHz using a recently calibrated IFR-1200
for a source - that was close enough for me.

Here's his website URL: http://digilander.libero.it/ik3oil/menu_eng.htm

I am looking to build a frequency counter, or buy an inxepensive kit.
Any recommendations?
Needs: low cost, few parts count
Thanks
