Re: xtal issues?

btw, I see this same response curve regardless if I use my homebrewed CTF, or the N5IB version (i.e., PCB with amp).

I've also noticed, that the high frequency side of the curve is less distorted with the crystals having a 3db bw > 100hz.  As the 3db bw approaches 80hz, things get considerably 'bumpier'...

I'd like to determine if this is my test setup, or simply bad crystals.  Any help would be greatly appreciated.
