Hi Megahertz!
I would agree with Charles and he is correct, power is typically the problem when things become "spritual" (technical term). The only thing I would question is the use of capacitors with the resonators. Are you certain the resonators require caps? Most resonators I have worked with do not require external capacitors. Second I am guessing that on the output of the voltage regulator you have a 1 uf cap as close as possible and then a larger value cap somewhere else? It is also useful to "sprinkle" .1 uf caps in various places on the power buss. Best, Ed
