[time-nuts] Yet another GPSDO project.

[Bob kb8tq]

Hi

How much impact your distribution setup has on the OCXO phase noise depends a *lot* on how quiet the 
OCXO is. If it is in the -170 dbc/ Hz range, then pretty much anything can mess up the phase noise ….

>> sure, I believe you since my primary requirement was phase noise. This is because I'd like to use the OCXO as reference for my spectrum analyzer and also for my HP 8663 signal generator to do phase noise measurements
