Thanks Louis,
I hadn’t realized it’s the semicentennial of that great storm; in the long run much good came directly/indirectly from subsequent research, including space weather instruments and models.
By that time I had upgraded from the superregenerative RX to BC453/4/5 and RME 4350, which with a Handbook-derived 807 TX and 300-ohm twinlead folded dipole allowed interesting QSOs in late May (I know where my log book is, that might be interesting)
One of the memorable findings from the storm: strong coherent global oscillation of 5 kHz to 8 kHz VLF emissions (originating in the magnetosphere), time-synchronized in U.S., Europe, and Japan (Harang 1968)
Thanks for the reminder; hope we can continue to make good use of equipment, data and models that began to evolve after the storm.
73,
