It's illegal in the US to change transmitter frequencies. Not sure where you bought the equipment, but you could try exchanging it. Otherwise, I'd say sell it.
Dennis-
The RC frequency police gonna kick down his door if he does?
I have changed the crystal in my receivers and transmiters multiple times without problems. This is with JR. If it was that big of a deal they would not make the crystals so easily removed and have replacements for every frequency readily available.
What about the high end radio's that can change frequency electronically, not allowed to use that either? Sorry for the rant, but I hate RC frequency nazis.
