[Elecraft] KTCXO3 - K3

[Bruce Beford]

Hello Johnny.
 
There is still no implementation of the temp vs. frequency data for the
KTCXO-3. You can enter the data into the Utility program, but it is not yet
used for anything. The KTCXO-3 does have better stability than the stock
reference oscillator, and in may cases meets the 0.5 ppm spec without the
implementation of the temp data. You still need to perform frequency
calibration using either method 1 or 2 from the manual. Or, with the new
K3EXREF board, the correction is done for you, if you are using a high
stability external reference. This works very well here.
 
I hope this info helps.
