RE: isnt a crystal a crystal?
If it is illegal to change the xtal in the transmitter, why can you buy xtal sets from Tower Hobbies that include both receiver and transmitter crystals? There is no warning about the legality of changing the transmitter xtal on their site details. You would think they should know what you can and cannot do and would protect themselves from any legal problems when selling these items.
I am not disputing the statements above concerning the legalities involved. I am just making an observation that doesn't seem to make sense.
