K2 4 MHz Oscillator Calibration

JT Croteau
Anyone know if the frequency counter mode of the MFJ-259B is accurate
enough to do the 4 MHz Oscillator Calibration of the K2?

Thanks

JT,

No way!  Wait until you have completed the K2 and use the method
described on the Elecraft website to accurately set the 4 MHz reference
using 10 MHz WWV or other accurately known frequency standard station -
follow that with a CAL PLL and CAL FIL to produce accurate dial
calibration on the K2.  In the meantime, it is not critical, so just set
the trimmer cap to its mid-rotation position.

If you want more information about doing the Dial Calibration steps,
check my website  http://w3fpr.qrpradio.com.

No.

Use the N6KR method, described on the Elecraft Website.
