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.)

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? 73 Bob, K4TAX On 11/2/2015 2:34 PM, Doug Hensley wrote: > I've been following the thread on using a 10 mHZ external reference and the > prospect seems both affordable and at least initially fun BUT I'd like to ask > is it really a practical improvement over Elecraft's available KTCXO3 > internal 1ppm reference?
