Interesting read on a low phase noise oscillator by Chris Bartram GW4DGU

There are several VHF crystal Oscillators designed by M Driscoll.
The one shown is merely derived from one variant.
It has an unecessary constraint on setting the crystal current.
Much better results are obtained by implementing the diode clamp as a
capacitively coupled peak to peak detector the output of which is
connected to a low noise dc source.
The crystal current can then be adjusted by varying the dc source voltage.
