The attached plot shows the sort of improvement in warm up time and
stability of a simple "oven" made by attaching a Darlington heater
transistor and thermistor to a Crystek 100 MHz oscillator, adjusted to
set the osc temp to around 35C and wrapping it all in foam. In this
application, a DDS clock for an HF transceiver, the result was well
worthwhile.
