The only C.L. Stong (W2PFM - great call!!!) article that I could find at QST came up in an archive search: "How to Cook a Ham" from March 1947
A story about not having safety interlocks and getting zapped. http://p1k.arrl.org/pubs_archive/28044 You need to be an ARRL member to access the file. I also searched for "Lightning" and found nothing about detecting nearby strikes, only about protection. Searched from around 1980 back through 1940. Same for e-field.
