[MRCA] GPS disciplined oscillators

[Ray Fantini]

Lot to be said for having everything run in the background from an external reference of known accuracy. Been doing manual calibration with the WWV thing for years but these days people expect crazy degrees of accuracy. Along with things like being able to look at a display and not have to do any thinking.
For $200 I will be getting something that's will keep everything accurate well below the resolution of my equipment and when I have people in the shop wont have to put up with stupid " this is my new BoFang that I paid $35 for and its got to be more accurate then your old stuff" statements.

Sounds like over kill to me for "hobby" applications.  You can easily adjust most standard time bases to WWV within a cycle or two. Most hams do not know how to do this using a simple technique of watching the S meter for cycling  or simply listening by ear, adjusting within a cycle or two will produce a distinct warble sound.  Even a BC-221 Crystal can be adjusted within a cycle or two.

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.
