Del, it is illegal to change crystals in your transmitter yourself. It has to go to either the manufacturer or to a service center like Radio South to get this done. There is more than just a band change. A change in the crystal will require transmitters to be re-tuned to the new crystal. If you do not, you take a chance of cross-intefering with someone on the adjacent channel and causing a real serious problem, let alone liability for causing the problem to begin with.

If you really need to change frequencies, then send it back for re-crystal and re-tuning, or buy another transmitter on the frequency you need to be on.

If you doubt what is being said here, please, go to the AMA web site and look it up for yourself.

Now, the receiver is a different story. It does not transmit so you can do what you want with that, but not the transmitter.
