What is Band Stacking? And QMB? How to use it? An demonstrative example in Yaesu FT-991/A.

Band Stacking is one of the nice features of the FT-991/A: It allows for three different settings for the same band. Be imaginative: Three different modes, three different settings, three different operation modes - all in the same band.
QMB on the other hand, is a 5-memory round-robin quick access memory, intended for quick storage and quick recall.
See the examples in the video!

Perfect explanation and demonstration of the Band Stacking... 73

Thanks a lot Dave, I appreciate it!!!

Hot damn, always learning something new about this radio. Thank you! -73

It's hard to explain that in words - so I thought the video would suit better! Thanks for the comment!

Excellent, thanks. 73, VA3HDL

Hi! Can I just clear the QMB entries? Let's say I store there a frequency of a station calling CQ in a contest which has a pile-up and I want to check it later. I could quicky jump to its frequency and back. However, after working it, I'd like to clear it, otherwise, old rubbish will be kept in the remaining banks and by short-pressing the RCL/STO button, I have to cycle through already "expired" frequencies...

[@rodrigofreire7604]

Hi Ferdinand! Man, you can't "clear" the content. You can surely replace them all with some other content to avoid confusion. But clearing content isn't possible for QMB.

[@ferdinandfrozenstein]

@@rodrigofreire7604 Thanks. Fortunately, for the sake of usability in my case, a short press of STO/RCL goes for the latest stored frequency and V/M jumps back. So there is no need to jump through the whole QMB stack every time you want to quick-check the CQer whether the pile-up weakened... On IC-7300 you go back by the same MPAD button, so you cycle throuh the whole stack to get back to the original frequency, however, you can clear the buffer, so it's fine too.

​@@ferdinandfrozensteinthis was the missing piece for me! Thank you so much! 🙂

Can it auto scan your stacking settings?

[@rodrigoabfreire3490]

No. The stacking has to be accessed manually by touching the the respective band button; there's no scanning between the stacks.
