There have been some reports of transmit drift in early KX3 units,
especially modes that are long duration, like JT65.  A modification has
been made in the firmware that allows for making a custom temperature
correction curve that is used to compensate the oscillator as the PA heats
up.  It changed the situation for me on JT65-HF from one where my transmit
signal would vary unacceptably over a 48 second period, to one that is
entirely acceptable.  The calibration process does require access to a
stable signal source (like a K3 that is warmed up and in a steady-temp
room).
