I bought a euro Yaesu 991a . The vhf/uhf band plan is severely limited for use in the US . I have tried the button presses as shown for the earlier 991 and the service mode works to open the frequency for transmission but setting offsets etc are not possible . There must be a permanent fix because service mode shows than the unit can actually transmit on the US band plan. Any help would be appreciated

This YouTube video says that pressing FAST + A/B + A+B during power-on puts the radio into Service Mode, allowing you to extend the transmit frequency range. You must follow the steps indicated in the video precisely; in particular, you must set the radio's transmit frequency to the range on which you want to transmit before putting the radio in Service Mode.
