This is from February 1917 QST Magazine. Adam R. Miller 8AKM submitted his list of "callsigns heard" and QST printed them. I listed him as being licensed in 1917 but he probably was licensed sooner. We just don't have the proof.
Note the 9ZN one of the best in the bunch. 9ZN of Zenith fame would be in partnership with one of Greenville's own Karl Hassel a year after this logging.
