[Elecraft] K3 with 2m add on - RefCal?

[Bruce Beford]

TJ,
It "may be" right. But without your refcal values, can't say for sure.
However, your results do seem to be lower than typical by a factor of 10.
You may have missed a decimal point somewhere. i.e. a more expected offset
would be 470 or 490 Hz, not the 47 or 49 you indicate. Check your math,
and/or post your refcal value.
The proper setting of the refcal calibration is important as a first step,
also.
