[Elecraft] ksb2 tx/rx alignment

[John R. Lonigro]

Neil:
I've tried several methods to get my K2 exactly calibrated:

One way is to tune in WWV on CW and use spectrogram to observe the 10 
MHz carrier.  If your sidetone is set to 600 Hz, tune the radio until 
the peak of the carrier is at the 600 Hz marker.  If it doesn't read 
10.000.00, adjust it using the method in the manual.

Another way is to use your ears and adjust your tuning until the WWV 
tones on USB have the same pitch as on LSB.  Since you can only tune to 
within 10 Hz, you may not get exactly the same pitch, but you can get it 
pretty close.  At that point, note the display frequency and again 
adjust using the standard method in the manual.

Trouble is, I get slightly different results when I use those two 
methods and don't understand why.  But we're not talking 300 Hz 
difference, more like 20-30.  If anybody can explain this to me, I'd be 
interested.  I have a feeling the second method is more accurate, but 
don't know why.

73's,
