[time-nuts] locking oscillators - an increase in power and/or stability ?

[Didier Juges]

That would only work if the impedance of the source was much lower than the impedance of the load. That is extremely unlikely in high power systems (at least in well functioning high power systems), but I heard that modern LNAs do not always provide the best noise figure when matched, so maybe that was the reason for that observation?
