Not relay looking for big improvement or anything with the big Harris radios, just maybe trying to find another reason to justify the purchase and next building of the distribution for the box. Have a Motorola service monitor and Agilent spectrum analyzer that I use all the time and think they are accurate to within maybe ten or one hundred cycles and not wanting to send them out for annual calibration I figure that with this box I can get to one cycle or so that would be good.

A Cesium Beam standard would be perhaps the coolest method, but a  GPS disciplined oscillator got to be next and way better than my old method of beating the oscillators against WWV.
