Can someone please explain how to access the advanced service menu on a China-made transceiver like RS-928 150 W? I accidentally restored the unit to factory settings; the firmware is version 1.05q. Since the reset, the amplifier only puts out 65 watts on 21 MHz, down from the previous 125 W. I need to access the menu to correct the band gain factors.
