I will be needing a 1st LO at around 48 MHz. That seems to be in the 3rd overtone area.
But a strange question just popped up.
Does every crystal have useful overtones or do they have to be specifically cut to have that?
I mean, could I take any, say, 16 MHz crystal, use in a 3rd overtone oscillator and get something out in that band?
(not necessary the same frequency, I guess, but ... )
Unfortunately, I am somewhat out of my league here. 10 MHz analog is usually my upper limit
