[time-nuts] What's the best way to double 10 MHz to 20 MHz ?

[Mark Spencer]

Yep.  But in this case the original poster was looking to improve stability.   Perhaps a better way to have phrased my comment would have been to ensure that the phase noise is not degraded vs the original xtal oscilator.   I do agree though that phase noise is very important.  As a side note I became interested in time nut topics after I purchased a gpsdo to compare the tcxo in my icom 706mkiig to.   I then needed to convince my self the the gpsdo was accurate etc (:

I did conclude that the tcxo in my icom 706mkiig was jumping by a few tenths of a ppm from time to time (:
