[NLRS] 10 MHz frequency standards

[tosca005 at umn.edu]

Which do you think would provide a superior 10 MHz frequency standard to 
lock a 10368 MHz transverter using an Apollo board?
  -- rubidium oscillator
  -- Thunderbolt GPS disciplined OCXO

I've been planning to eventually go the route of the frequency locked 
oscillator for my microwave transverters, and have a kit from Pyrojoseph 
(no longer being sold) to provide a GPS-disciplined 10 MHz oscillator 
source, but with my lack of time to build it up, I started looking around 
for a pre-made oscillator source, and found those two types mentioned 
above. Neither one is ideal for roving use, due to their DC voltage 
requirements (24v for one of them and triple supplies -- +5, -12, +12 for 
the other), but could be pressed into service with some effort.

Ideally, I am looking for BOTH precision and accuracy. It would be really 
nice to tune to 10368.1 MHz and know that I was within 1 KHz of the actual 
frequency so that QSO's wouldn't be lost by failing to tune around far 
enough, as has happened in the past. And it would be really nice to have 
the frequency stay stable from start to finish.

Any thoughts out there?
