Johan,

I just used a simple Pierce FET oscillator, followed by an LM6321 buffer,
and it worked. I have an air variable trimmer for rough setting, and a
tuning diode run by a 10 turn pot. I did glue a PTC thermistor to the
crystal to help with temperature. I'll know more about stability in a couple
of weeks.
