Clone board C22, C23

Clone board C22, C23

2018-04-01 by backshall1@bellsouth.net

Has anyone verified that it is no longer necessary to change C23 from 22pF to 10pF once you have C22 properly grounded? It looks like the missing ground on C22 was not discovered until a couple of years ago, although we've been trying for many more years to figure out why C23 and the resonator were not behaving as expected. I will be testing this as soon as I get some new boards from Jed.

I've done two boards with the the 22pF caps and the fixed grounding so far.
Both were/are rock solid - so I'll guess the missing ground was indeed the
culprit.
