[time-nuts] looking for SMT oscillator SC cut, with no oven

Hello, Jim,

I suppose that one of the alternatives that you've explored are the 
ABLNO from Abracon http://www.abracon.com/Precisiontiming/ABLNO.pdf

They say that they are 3rd overtone, but it seems more an AT-cut than a 
SC, and anyway is around 10dB poorer than your requirements. An I 
suppose that to make surgery in an AOCJY (that fully meets your 
requirement) to remove the oven will not be adequate :) Also it is a bit
