KTCXO3 - K3

[Johnny Siu]

Hello Group,
 
There are Method 1 and Method 2 for frequency calibration on P.50 of the K3 operation manual.  Has the calibration specific for KTCXO3 implemented?  Do I miss anything?  Or, simply, is there any frequency calibration needed for KTCXO3 (apart from data entry in K3 Utility) ?
 
 

TNX & 73,


Johnny VR2XMC

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.

Bruce, N1RX
