===============
Gary, if you have another receiver it's easy. Just set up the other rx for
JT65HF, transmit via the KX3, and look at the received trace. You can see
drift down to a couple of Hz.

I found the drift not to be too dependent on power level. Even at very low
levels of output power, my KX3 drifted about the same (about 18 Hz) before
the temperature compensation. This is too much for JT65HF communication.
