Shown here in the August 1928 issue of Popular Science is Upper Montclair, NJ, ham Charles K. Atwater (no relation to Atwater Kent) with his 10 meter transmitter. According to the magazine, Atwater had added another triumph for the hams, namely use of the “remarkably low wave length of ten meters.” With his low powered transmitter, he established two-way contact with two stations on the Pacific coast, and had earlier made contact with Arachon, France. The French contact was apparently with F8CT, as recounted on this page.
Atwater had been a ham for a while, since he was listed in the 1916 callbook and 1921 callbook with the call sign 2JN, with an address of 40 Oakwood Avenue, Upper Montclair, NJ.
He remained active, as shown by this one-transistor transmitter circuit he submitted (with his call now W2JN) in the December 1955 issue of QST.
According to QCWA, Atwater died in 1980.
I was really pleased to see my father’s accomplishments describe in this short article. He was such an active “ham” for more than 70 years. We had a 40 foot tower in our Montclair NJ backyard, it think it was to facilitate his 40 meter contacts. His first contact with Arachon, France has been reported in a few articles on the internet. Someone else now has his call letters – W2JN.
