Charles E. Apgar in his wireless station
Summary[edit]
| Description |
English: Amateur radio operator Charles E. Apgar operating his wireless telegraphy station in Westfield, New Jersey. Original caption: "The Radio Detective Who Unfathomed the Famous 'Nauen Buzz'" "During the early days of the World War the incredibly rapid and undecipherable radio signals between the most powerful broadcasting station in Germany and the station of the "Telefunken Company" at Sayville, Long Island, N. Y., aroused the attention of the U. S. officials. But it was radio amateur, Charles E. Apgar of Westfield, N. J., who finally found the solution by means of amplifiers that recorded these signals on was phonograph cylinders. By this means the messages were de-coded – and the Long Island station was promptly seized. This picture shows Mr. Apgar operating the same apparatus which he used on that historic occasion." |
