[time-nuts] 10MHz standard for comms receivers

[Bob Betts]

Hi All. Over the years, I have experimented with WWVB and GPS and Rubidium timing to establish a 10MHz Standard for LO sync in communications receivers. My career has kept me away from the hobby for some time and, frankly, I am not very well versed in some of the timing techniques that I read here...actually I'm just a hacker. Anyhow the thought occurred to me that with some of these newer computer clock timing systems, that a (for example) a 3GHz clock could be divided down by 300 to obtain a fairly tight 10MHz reference. It does have an effect on SDR pgms, but I'm curious about analog systems as well. It would seem (to me) that whatever error there may be at 3GHz, that it would also decrease to a tighter tolerance during the "divide by" process.
Okay, so I've been an RF and Audio products designer for 55 years and really (probably) shouldn't venture into territory unfamiliar to me. But this part is a hobby...so how's a guy supposed to learn. 

Will someone please explain the errors in my thinking? it would be appreciated.
