“Amateur radio operators who have picked up messages from Arctic explorers and from the Dyott expedition now following Theodore Roosevelt’s trail down the River of Doubt through the jungles of Brazil are likely to hear dispatches from Gordon MacCreagh, exploring in Abyssinia.
“When Gordon MacCreagh, American explorer, left New York on the Abyssinian expedition, Feb. 10, long and short wave radio traveled with him. Some of the equipment carried was that which Commander Richard E. Byrd took in his airplane on his successful flight over the North Pole.
“This apparatus consisted of a broadcast receiver, and a CR-18 short-wave set designed by A. H. Grebe & Co., Inc.
