Hello list, For those of you interested in phase noise measurement without using fancy/dedicated gear,
There is no free lunch here. The crystal has its own intrinsic flicker of frequency noise. You cannot measure below this noise floor. The technique you are talking about could be useful in particular applications, but is not a general replacement for "dedicated gear". I don't even see where this is simpler than mixing two oscillators in quadrature. In that case, the only RF component is a mixer and everything else is audio. Also, when using a crystal filter, you have to be careful not to overdrive the crystal.
