Dave,
Put the external reference oscillator input option on your K3 and avoid
that situation with an external 10 MHz reference oscillator.
The K3 Reference Oscillator temperature steering is from the static
temperature offsets. If you have equipment to do better than the Data
Sheet, you can determine your own values, but for those without that
equipment, the data sheet provides a good index for various temperatures.

Yes. I'm a stickler for accuracy. It always bothered me that the
so-called 'temperature compensated' LO in the K3 was not actively being
steered by temperature compensation (i.e. I could only put static
temperature offsets into the rig memory from the data sheet that came
with the oscillator). That was a 'feature' that was never released. At
HF frequencies, it was only an annoyance, but using UHF transverters,
the error compounds (I'm using a crystal oven in my UHF transverter, but
the lack of one in the K3 caused drifting).
