Good advice. Also be aware that the center frequency differs depending on mode. For example, it is the supressed carrier frequency on SSB but is offset by typically 600 Hz on CW.
I like to use AM mode for frequeny calibration. After doing a frequency calibration on the K3, tune to a signal on the AM broadcast band and adjust the P3 frequency calibration. (MENU:RefCal. Cal procedurre is on page 39 of the manual) As I recall, AM broadcast stations are required to be within 20 Hz of nominal frequency but are typically much closer than that.
