What method did you use to go "out of band"?
You might be able to reload the original or default "code plug" for that model to get it working. You did save the original didn't you???? Then read it and use the Shift Key method to enter the frequencies that are out of the original band limmits. You can not go too far out with out the radio acting up, not locking the VCO, ect;.
Most GP300's VHF go to 144 mhz, and UHF go to 440 and 476 without problems. You can go to 486 on a UHF receive only!
