[Elecraft] P3 Manual Calibration procedure question

[Tommy Alderman]

I'm sure this has been discussed before but if so, I have missed it.

On page 24 of the P3 Owner's Manual, Rev. B, March 29, 2011, under the
heading of Amplitude Calibration the forth button down, it states to set the
signal generator for 7040  kHz and the following button below says to set
the transceiver to approximately 7015 kHz so the signal is centered on the
right half of the display. Is this a typo? If not, can someone please
explain the purpose of doing this?

Thanks and 73
