SOURCE: Freq change GME GX300 from 27Mhz to 29Mhz
Hold down the 88/pri and the DW buttons while switching on the radio into programming mode. You'll then need the programming soft and hardware to read the radio., add the 27mhz channels and write it back to the radio. The GX300 can only store additional freq. in the p1-p0 modes
