[time-nuts] YIG oscillator drift question

[jmfranke]

I do not have any data on temperature drift, but I can say that most YIG 
oscillators I have used, with the exception of the Stellex-mini models, have 
required a tuning current to oscillate. The Stellex-mini models have a 
strong bias magnet which allows the tuning current to be zero at mid tuning 
range.
