150B aboard the “Jacob Ruppert”

Often published 1934 photo of Guy Hutcheson posing with one of the 150B transmitters employed by the Byrd expedition to Little America in Antarctica.
Mr. Hutchenson was the Radio Operator aboard the “Jacob Ruppert” (KJTY) and Operator on the Ice Party.
The second 150B was flown in a Curtis Condor to a position on the ice near the South Pole where Guy operated the unit to communicate with the aircraft.

The second image is of Howard R. Mason – another one of the radio operators serving on Little America’s base radio station, WFA.
