[Elecraft] K2 VCO Table (Appendix B)

[Don Wilhelm]

Jeff,

The VCO frequency will always be the K2 dial frequency plus the IF 
frequency for all bands through 17 meters.  For the bands 15 meters and 
above the VCO will be at the dial frequency minus the IF frequency.
Yours are all correct.  The manual list is correct for an IF frequency 
of 4915 kHz, but the actual IF frequency is closer to 4913.

You will obtain results that are closer to the published list if you set 
the K2 to 24890 kHz which is the low edge of the 12 meter amateur band.  
Your results are correct for having the dial set to 24800 kHz.

73,
