At one time there were crystal manufacturers who would custom make any
frequency of crystal desired. Don't know if any of these places exist
any more. How about a 20 Mhz? Would that be close enough? Or how about
some surplus electronics stores? I've seen odd frequencies at these
places, like 11.582 Mhz, etc.
