Although they can take a couple of months, there is a Czech firm (https://www.krystaly.cz/en/products/quartz-crystals/) that will make crystals in almost any frequency. My most recent order for a 2.3067 MHz HC-49/U part was $20 each plus $8 postage.

Granted; there can be spurs.
But between a few spurs, usually on some other freq,
and a DEAD rig because *if* you can find crystals,
they're $65 each with delivery weeks or months away,
I'll live with the spurs.
