[Elecraft] [P3] Adjusting Center Freq in Narrow Span

[Don Wilhelm]

Al, I would start with the Calibration Reference Oscillator Calibration 
as indicated in the manual (use Method 2).  After doing that, the K3 ref 
osc calibration should be correct, and all other discrepancies should be 
with the P3.  Refer to the P3 documentation for corrective actions.
