Sorry you feel that way, Steve.
The K3TCXO-1 that came with my K3 has a calibration/test sheet that
clearly indicates that it is accurate to within 1 ppm. This has nothing
to do with firmware. The setup procedure in the manual that is currently
not usable is the procedure that will make the TCXO-1 accurate to within
0.5 ppm by use of firmware. Of course, I could be 100% wrong, but I
don't think so.
From the K3 Order page...
"KTCXO3-1 TCXO +/-1ppm (f/w corr. to 0.5ppm)"

The setup for the 1 ppm TCXO is not enabled; I'm not sure what that
means vis-a-vis the stability. I've only had my K3 for a short time,
and haven't attempted to monitor the stability.
Bottom line: a product is being actively advertised and sold, but the
buyer is not told that they will not be able to use it as advertised.
Glad you're seeing excellent stability. Perhaps I'll play with that,
and montor WWV over an evening....
Thanks/73!

Unless I misunderstand what is published, the firmware for the 1 ppm TCXO is
only to allow it to be tightened up to 0.5 ppm, and does not affect the
basic 1 ppm TCXO. I have the 1 ppm TCXO and even though I haven't done any
scientific calibrations, I'd say it has a 1 ppm capability... or pretty darn
close to that.
