- Cheap 10.111 MHz crystals are sometimes available in bulk for a few cents each. They're handy for 10 MHz homebrew CW transmitters. How well do they work in a VXO circuit?
In this video I try two crystals in parallel. Series L and variable C allows stable coverage over the CW end of the band. The oscillator is even stable enough to key if desired.

Peter, do you think doubling up on the crystals again to 4 or even 8 would have an effect?
