If your goal is, as Jim guessed, to get 24MHz from 10MHz and
you are using something like an RTL-SDR, then how about just
passing the 10MHz through a CMOS gate to square it up and
get nice harmonics, then pass a wire close to the crystal.
This should injection lock the crystal to right frequency.
It wont be a strong lock due to the 5:12 ratio, but for something
like a crystal that is already quite close, that should do the trick.

Alternatively, using an ADF4002 with a small uC to configure it
and a VCXO/VCO should also work.
