Hi Gary,
Thanks for the capture. Conditions have been pretty good lately.
I'm aware of the drift. The dds synthesizer that I built uses a reference
oscillator that is not temperature compensated. When I'm down in the basement
radio shack/workshop I turn up the heat and the frequency drifts downward. When
I'm done for the night I turn the heat back down and the frequency will drift
upward. Sometimes I will 'manually correct' the frequency so I don't run into
XES (1/2 Hz or less lower).
Perhaps I could publish a chart on my web site that shows the temperature in
the shack as a function of XGJ frequency :-)

Hi All,
I seem to have recorded a slight shift in frequency on Warrens XGJ signal,
it occurred about 0045z (27/10/05) & moved back at about 0345z, the other
signals (XKO, NA & Loran lines) show no shift. Are you aware of this Warren?
& did anyone else see the shift? See attachment, its vertical so you can see
the comparison, the time line on right is 0100z.
Regards,
