[time-nuts] Locking gunn diode

[Didier Juges]

Hittite has dividers (prescalers) that go to 18 GHz:

I have a couple of samples of the :8 that goes to 12 GHz, precisely to 
try and phase lock a Gunn, which I have not used yet (another long 
winter project that won't happen as long as I am in Florida :-)
