sTef,
Surely you can receive some standard station at a known stable frequency
and use Method 2. While WWV is suggested, that method will work with
any station having a know stable frequency.
Method 3 had been discontinued some time ago.

Hi Gang, Hi ELECRAFT,
I own a K3 S/N 3783.
Due to the the discontinuing of the K3 I now ordered the 1 ppm TCXO. All came
in well as expected, except of one important piece of information.
Referring to my original paper printed K3 manual Rev. D Sept. 2009 page 50
"Reference Oscillator" there are 3 methods to calibrate the TCXO.
Using the mentioned "Method 3 (1 ppm TCXO option)" the manufacture delivers a
data sheet which has to be used to calibrate the 1 ppm TCXO.
But there is no data sheet delivered by ELECRAFT.....
Methode 1 und 2 are NO sophisticated ways for me to calibrate such a 1 ppm TCXO.
Two questions, please:
1. Can someone from ELECRAFT please give me an explanation on that issue?
2. Would the calibration of the 1 ppm TCXO be obsolet when installing the
external reference option K3EXREF?
