    We had a number of enthusiasts with experiments on WSPR and VLF (and one lucky sole seeing the real thing in Svalbard). The largest effort was having three SDRs record the LW and MW broadcast bands over the full three hour period. I have been adding results to the Chelmsford club eclipse page. One of the standout ones is BBC Radio Scotland giving a double peak during and just after local totality

    The initial coarse-timed plot was at 30s intervals, RadioScotland_1.png

    but then I re-plotted totality at 10s intervals RadioScotland2.png

    and listening to it on replay its certainly very noticeable as the audio pops up by ~10dB out of the noise along with that middle dip - anyone else seen something like that?
