When you say the EFC voltage changes by several millivolts, how much does that change the crystal frequency? if it is not confidential, can you say what kind of phase detection you use in your GPSDO? On your page at http://www.jackson-labs.com/products_fury.html it states: "Allan Deviations of less than 1E-011 are possible for measurement intervalls greater than 0.1 seconds." What kind of counter do you use to measure that data point? Further down on the same page, it states: "A high-end Motorola GPS receiver" Can you tell what kind of Motorola GPS you use? Finally, do you have a price list for the OEM and commercial products?
