I'm surprised there hasn't been much discussion here of this topic already, but let's give it a go before it's too late. First, what's it all about? This sorta pop-sci intro from BBC explains the basics, albeit with considerable misuse of the word "broadcast":www.bbc.com/future/article/20231005-eclipses-do-odd-things-to-radio-waves-to-learn-more-an-army-of-american-amateurs-will-broadcast-during-the-next-ones
The event will have measurable effects on all long distance radio wave propagation from VLF up to at least low VHF. (This includes Part 15-type LowFERs and HiFERs, as well as hams, AM broadcasters, WWV, WWVB, CHU, Navy VLF sites, etc.)
The HamSci site goes into more detail on at least some of the amateur radio projects planned for the eclipse:

Location and some basic timing guidance on the eclipse visibility is given at:

These are offered as mere starting points for discussion. Begin!
