CASPER TRIBUNE-HERALD, 1937
Pacific waves — Three days after the disappearance of Amelia Earhart, the July 5 edition reported on page 1: “Rock Springs Boy Picks Up Message from Flier ...
“A 12-year-old colored boy, Charles Randolph, had the thrill today of having done his share in the search for Amelia Earhart and her globe encircling companion, Capt. Frederick Noonan.
“Randolph twirled the dial of his small and inexpensive short wave radio set Sunday morning [July 4] about 8 o’clock. Suddenly he was startled when he heard what he described as a faint but distinct voice saying ‘Amelia Earhart calling.’ Over and over again, he said he heard the call but could distinguish no call letters such as the missing aviatrix would have for her radio station.
“The lad called his father, Dana Randolph who rushed to the telephone office where he contacted the wire chief, who in turn notified a department of commerce bureau of aviation official who happened to be visiting Rock Springs.
“The three rushed to the Randolph home where the lad told his story.
“The signals, he said, came in for 25 minutes before they faded out.
“He said he could hear something about a ‘ship being on a reef south of the equator,’ and added that some unintelligible figures also were given which may have been latitude and longitude, but he was unable to copy them down.
“The department of commerce official and amateur radio operators here said it was possible that Randolph may have received a radio call from the missing flier.
“The youth is not a licensed operator.
“His report was forwarded to San Francisco by the aviation official for what it was worth.”
