[Elecraft] Auto-spot, tuning aids, and the arcane history of CW pitch-matching

[Bob McGraw K4TAX]

Another trick which works well.   Tune to a WWV frequency in CW mode.  
Press SPOT and the radio will jump on the exact carrier frequency.   The 
SPOT function can pull on to the WWV frequency as far away as about 100 
Hz.  Once the radio has  resolved SPOT, the readout / display is the 
frequency of WWV +/- the error in Hz. Thus the readout of 9.999.992 is 
indicating being 8 Hz low.

 From a cold start, FP being 19°C, I find  -8 Hz error on 10 MHz WWV.  
After about 15 minutes the FP is 25°C and the error is -1 Hz.  I've 
tweaked the REF CAL such that after 1/2 hr. in receive tuning to WWV 
from both higher and lower will produce a reading of 10.000.000.   Will 
all stations pse QNZ  QNN.
