[time-nuts] quartz oscillator injection locking

[Francesco Messineo]

Hi all,

what would be the best method to try injection locking a butler common
base crystal oscillator (see figure in
http://www.eska.dk/oscillator_data.htm for schematic)?
Any comment about close-in phase noise performance when adding
injection locking to such oscillators?
Thanks in advance for any hint.
