If you do the same, DO NOT buy the ridiculously overpriced 'RT42' programming cable which is just a bog-standard USB-A to USB-B lead (as commonly used on printers). So for £21 ($25) I decided to bite the bullet and make the purchase.

I'm not a fan of paying for 3rd party programming software and I always espouse the use of a manufacturers (free) software, but in this case, there just doesn't seem to be any! RT SYSTEMS software will allow you to program independent offsets so they have either got a friend at Yaesu or they've figured it out themselves. Sorry to whinge, but it really does cheese me off when a manufacturer sells you (an often very expensive) radio with thousands of memories but no way of easily inputting them via computer software. I was originally going to try running it SPLIT but it got kinda messy so I looked for other options. Apparently, Yaesu don't document how to set a repeater offset for a specific memory channel - only the direction. I tried to find a way around this and even looked at VK2BYI's software to see if I could edit the file but sadly it's not possible. That's fine most of the time, but what if some of the 70cm repeaters need a 1.6MHz shift and others need a 7.6MHz shift? You're stuffed!! 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.
