49.380 MHz Oscillator Calibrator

[ke9uw]

I measure my 49.380 MHz osc to be 49.379790 MHz. Anyone check theirs?

Hi,
After calibration to WWV on 15 MHz, I have, 49.379872

Chuck, If you are asking or concerned  about the operating frequency of a
XG50 signal source- The absolute frequency is not important. It is meant to
be a relatively stable frequency source, not a particularly accurate one.
When used to due the temperature compensation routine on a KX3, it is only
important that it not drift significantly in frequency during the procedure.


In this application, the actual operating frequency is not important, but
stability is.

Yes thanks. I see that the frequency is just required to be stable for the gathering of the KX3 drift from it vs temperature. I mistakenly thought it was freq accurate and did the room temp ref cal at the end with it. After I determined what freq it was, the room temp ref cal was right on. Now that I think about it, I'm not surprised.
