no tuning, but you *do* need some adjustment range, right (it needs a
voltage control port?)
what about one of the TCXOs out there that has the "resistor trim" for
frequency?
Just randomly.. A Vectron TX400 has a +/-12 ppm tuning range on the EFC
input.. that's about 1200 Hz...

Digikey shows a whole bunch of Crystek VCOs for around $20-30
