Change step size to 5 kHz by pressing F and 3 and rotating dial knob one click to the left. Display reads 05.
Press F and 9. Display reads 05.00. Change it to read 30.6350. The last two digits look like a tiny [50]. It takes many turns of the dial knob to do this step. Pressing the function button while turning the knob will speed up the process by incrementing in 100 kHz steps.
Change step size back to 10 by pressing F and 3 and rotating the dial knob one step to the right. Display reads 10.
Press F and 0. Display reads 433.00.
Press 7. Display reads . (period)
Press the numbers 3 0 6 3.
Press *. Display reads 430.00.

Turn the radio off and then back on again. This restores the keyboard direct frequency entry feature.
The modification is now complete. The radio will now receive and transmit from 430.00 to 463.995.
Now you can use the F and Mhz buttons to set the RX/TX frequency changes:
Example:
Set the range to the US Amateur band only (420.00 to 449.995 mHz)
Press F and 0
Press 7. Display reads . (period)
Press 2 0 4 9
Press *
This sets the range to be 420.000 to 449.995 mHz.
Example:
Program 400 to 469.995 mHz
Press F and 0
Press 7. Display reads . (period)
Press 0 0 6 9
Press *
This sets the range to be 400.000 to 469.995 mHz.
Note: it is recommended to stay within 418.000-469.995 Mhz to be safe.
