i think the -10 or -12 meant the channels.

Did you change the crystal on the Tx to -10?

Correct, Type is not frequency for Futaba crystals. Good that you got yours figured out.

For what it’s worth the info is available on the Futaba site, check the chart on the bottom right for a basic description of types. For the OP a difference between Dual Conversion and short FM crystals.
