    Yep. Look at it as 'modulation of a waveform by a second frequency', thus constructive and destructive interference.

    The Maunder minimum is indeed a reference to an historical 'null' in sunspots, caused by that beating (as above). Because we may be heading into another such period this century, the term has been extended in use to refer to any future long-term null in sunspots.

    It is unfortunate that whether or not solar activity controls the global changes in warming is now a huge political issue, but clearly its the dominant factor. See, for example:

    http://www.petitionproject.org/review_article.php

    The gist is the 'human' issue is whether the extant effects of CO2 warming will mitigate the cooling effect of a new Maunder minimum. If not, despite fears of run away climate heating, the reality will be another 'Little Ice Age' with that new Maunder minimum--if we didn't have the CO2 heating.

    The prediction is global warming for another 10-15 years, then a decline and plateau, similar to today, for 50-80 years.

    I wonder if any heliacal sidebands are generated?

    I agree with KA2DDX and today,20 meters was hopping with cw,psk,ft8,olivia and JS8 into night. Been trying to find where PSK OPERATORS are on 30 meters now. After dark, 40 and 80 come alive. Couldn't believe it! I called cq once on on 7.071.60 khz and g8dks came back to me on olivia 8/500 and we chatted for 50 minutes with S7 to S 9 signals! Last week Monday, a YB9 station called me on 20 meters OLIVIA 16/500. The band conditions were marginal at best and he faded out after 10 minutes and this was about 5:30 pm. Remember last winter,spring and summer that wonderful sound of receiver HISSSSS and thunderstorm lighting crashes??????.

    Looking forward to SC25. I am sure it will be fun and I will work more new ones for DXCC HR and work more DX / TEP on 6m. Not concerned about the predictions at this point. Hope to have a couple more cycles before hitting the dirt.

    The editor in me fixed it for you (free of charge). I had some extra punctuation and question marks laying around that were eager to help out. :)

    Thanks for your videos! I live in Michigan and talk to Hawaii and Italy most everyday. Even had some activity on 15! 20 is always busy with dx from the east in the morning!
