49.152 MHz crystals can be obtained in fundamental mode (mostly in SMD package; 5x7mm is not too difficult to work with, but smaller packages certainly are), however, check datasheets carefully and confirm with manufacturer if in doubt, as many also are offered in 3rd overtone or don't specify. Above 49.152 MHz, fundamental mode crystal seem to be rare.
That said, I believe the project should consider making the 45 MHz filter normally used in the project available for sale to homebrewers as a component or spare part (perhaps in quantity increments of 1, 10, 25, or something like that); this would greatly help those that want to duplicate or otherwise follow the commercial design and help support volume purchases by the project from OEM in China, and would help homebrewers focus on individually interesting parts of the design without having to resort to making individual design changes in that part of the circuit.
