No in FM crystals there are S and F type crystals. My first order with Sport crystals I received the same FM frequencies in an "S" type crystal and they did not work. I had to send them back and get them replaced with the "F" type. I guess the crystals can have a different impedence, and this counts. As I mentioned I bought these Xmod crystals and none of them worked, much like the "S" crystals made by Sport crystal did not work.

You must get the "F" type. F stands for Futaba I think.
