Dan,
You may change the receiver crystals, but you cannot change the transmitter crystals in any radio as it is against FCC regulations.
To change the crystals in a transmitter, the radio MUST be retuned to the new channel by an authorized service center.
I hope you find this information helpful. You can also reach our product support technical team at 217-398-8970, or via fax at 217-398-7721.
Sincerely,
Krysta
