[Elecraft] 10 mHZ external reference VS the K3S's optionalKTCXO3-1

[Ron D'Eau Claire]

IMX, such pursuits of precision become a hobby in themselves. 

I'm old enough to remember that when I first built a VFO (ca 1953), if I wasn't responding to a CQ I was always careful to be sure there was at least one QSO between the frequency I was planning to use and the band edge. That way I had a decent chance of being "in band" since I really had little idea what frequency I was on otherwise. (And it wasn't remarkable that the station I was working wasn't particularly sure either.)

Bob,

Thanks for asking, I too have struggled to understand the need given I only use the original digital mode, CW and SSB.

:-)

Yes, I've been following this as well.  And to that end, I have a commercial GPS Disciplined Oscillator that is used as a reference for the test equipment in the shop.  In checking my K3s I find, with the 
optional TCXO, the accuracy is typically +/-2 Hz on all bands.    Few if 
many other transceivers will display or maintain this stand-a-lone accuracy.  So I ask, what's the obsession with accuracy better than this for amateur use?

Or is this just a way to achieve more accuracy at less cost than the KTCXO3 ?  Isn't the K3S better served with its own oscillator?  What am I missing here?
