Have a look for a patent by Bart McJunkin and his 'cartwheel' oscillator. It amounts to a vert short length (0.062 inches) of very low Zo coax, resonated with an awful lot of paralleled varactors.

They work very well indeed.

I'll have a look for that, I've never hear of it before. In the past I've done research work into UHF/microwave oscillators that used defected ground as part of the resonator and feedback path. The idea was to achieve low microphony and a low parts count.
