Here’s a waterfall showing the 80M CW band from a bit after 1600 UTC (noon) and 2000 UTC (4:00PM EDT) on eclipse day. There was clearly enhanced propagation for about an hour, starting ~15 minutes before the local maximum (73% obscuration) at 1819 UTC. There aren’t many signals shown at any time, but that’s to be expected at mid-day in this frequency range.
In order to show this long time period, the waterfall only updated every 60 seconds and I think there is quite a bit of time detail lost — i.e., there may be more stations than are shown in this display. Further work will hopefully improve on this first snapshot. I want to get the call signs of as many stations as I can, and also tighten up on the time precision.
