If you don't find the 10836 or 10564kHz xtals you might consider using a
xtal on the 3rd overtone, that would be 3612 or 3521kHz. These are
frequencies in the 80m band, so much greater chance to find them among

hams.

But beware; the overtones are not exact multiples of the fundamental
frequency. In the examples above the frequency difference with the third
HARMONIC could easily be 10kHz or more.
