Jim Miller:

  I have seen vfo ideas with resonators for 144 MHz to micro wave in the past.  
I understand you are wanting to divide that down.  I know that some low drft 
models have been made.  If the frequency is divided down numerous times it 
appears then that the phase noise and drift both will be cut down numerically 
also.

  These oscillators they make today in a single package at such high 
frequencies do tend to be fairly good on noise and drift.  So I think I can 
understand what your thinking.  I will check out the material by Harold Johnson 
and see more of what you are saying.

  We know that sometimes the manufactures of stereo equipment can come up with 
stable vfo ideas for the FM broadcast band and did so in the 1970 era models 
before PLL design became popular.  Back when they used allot of Class A audio.  
You can't hardly buy a stereo today that measures up to the 1970's era: 
Pioneer's are cheaply made today.
