I too have been looking at a low phase noise crystal oscillators around
100 MHz for use in a Tayloe Detector design for a 50 MHz DC receiver. I
was going to use a circuit found in QEX (90 MHz oscillator for a 6 meter
transverter, Sept, 1995, page 27), but have been questioning this choice
with the interesting reference below and the following reference:
The article by Chris Bartram referenced below has a diagram of a
Driscoll Oscillator, but it is unreadable. Does anyone have a better
copy of this diagram?

I am considering buying the Time Machine for use with my 432 to 28
Mhz transverter for EME and Linrad. I want to get the daughter
board to use with it. That means that I need to make a 112 MHz
crystal oscillator to use the Time Machine with the 28 MHz output of
my transverter. Does any one have a suggestion for a good circuit
for a 112 MHz crystal oscillator using a 5th or 7th overtone
crystal? Of course a low phase noise design would be best.
Terry have a look at this link, it may help.
