In the menus you can alter the setting for repeater-shifts and every time you choose + or - when programming a memory, it will apply the shift which you inputted ( say -600 for 2M and +7600 for 70cm). This wouldn't be so bad if it wasn't for the ridiculous single repeater shift for each band! Check your version number to confirm everything has changed to the new version.Īs is often the case with Yaesu, the FT-991A doesn't come with any programming software, so you are expected to hand-ball everything into the radio via the front panel. Once you've completed all four updates, you'll be told to switch off the radio and then back on. Carefully read through Yaesu's Firmware Upgrade Manual before starting the process and have it to hand throughout. The updating process will take about 20 minutes. You should update in the order shown in the screen above, starting with the Main. If you don't update all four, your radio will likely stop functioning. Bear in mind that there are actually four update processes involved and each one is totally independent to the other. If your 'MAIN' version number is lower than the one on Yaesu's website, then go ahead and perform an update.
