K3 High Stability Ref. Oscillator!

Jim Harris-2
*Good morning, All.*
*
*
*I have K3 [S/N2802] with the latest Firmware installed.  I'm also using
the K3 Utility rev. 1.4.10.11.*
*
*
*When I ordered my kit, I also ordered the KTCX03-1 [0.5ppm] High Stability
Ref. Oscillator.  When I received this particular kit, with it came a data
sheet for the KTCXO3-1 with freqs at certain temperatures.  The "then" K3
Utility revision had a "link" that allowed me to input the data from
that accompanying sheet into the K3.*
*
*
*Has this "link" been removed?  Why, is it no longer required?  Am I
missing it within the current K3 Utility?*
*
*
*Merry CHRISTmas & Happy New Year!*
*
*
*Thanks & best 73.*
*
*
*Jim.........*

You need to enter that data for the TCXO to work right.  It is under
calibration....enter TCXO data..........

Jim,

The KTCXO3-1 has always been more stable than its spec'ed 0.5ppm
stability, so there is no need to calibrate it for temperature vs.
frequency using software.
Because of that fact, the fields for entering the calibration data have
been removed from the K3 Utility and also the section referring to
"Method 3" has been removed from the K3 manual.

In other words, since it is not needed, it has been removed.

73,
Don W3FPR

I just checked 1.4.10.11 and do not see TCXO under Calibration.
In 1.4.1.8, the latest version for Windows, the TCXO button is listed under Calibration but grayed out.  I've never seen it active, even though I have the TCXO.

My recollection is that Elecraft decided they didn't need the cal sheet in order to get the TCXO to work within spec.
