This mod that i am about to reveal only works on models that have the "green wire " on the bottom right of the keypad side of the radio. This mod could be done by anyone with a set of wire cutters and a small screw driver. All you must do remove the 3 long screws from the rear of the radio along with the one small screw beside the power button then remove the 4 silver screws along the battery tray and slowly open the radio at this time you should see the green wire laying on top of the white paper insulator. CAREFULLY cut this wire and then out the radio back togather. once you have installed all screws place battery back on tray. Turn on the radio while holding the up and down arrows located on the right side of the keypad. Repeat this step again. Once you have powered up the radio twice while holding the up and down arrows. Punch in the frequency 154.570 if the vhf side of the radio will transmit on this frequency than you have done the mod succesfully. Congrats and many QSO's KG4FYP Copied from the QRZ!
