[time-nuts] Re: Best frequency to start for GHz synth ?

[Bob kb8tq]

Hi

Unfortunately, even the numbers he quotes are going to be less than 
ideal if multiplied directly to 10 GHz. Will they be “good enough” for 
this or that? As always … that depends. It is rare to find any piece 
of commercial gear that does it that way.
