The CN-208 was the reference design for the SE-143 Navy Standard Shortwave Receiver of 1917. According to the “History of Communications-Electronics in the United States Navy” by Capt. L.S. Howeth published by the U.S. Government Printing Office in 1963: “Early in 1916 it was decided to redesign the type A and B receivers. The specifications for the new receivers were provided to the Washington Navy Yard and to the National Electric Supply Co., of Washington, D.C. The Navy Yard had completed the new designs of these receivers before the National Electric Supply Co. submitted models of their two receivers, the CN 208 and CN 239. It was discovered that the induction coils of these were superior to those used in the Navy designs. Production of type A, 1917, had commenced but was stopped after 40 receivers had been manufactured. Type B, 1917, was not placed into production. Modified specifications were immediately issued and the Navy Yard redesigned and developed their sets, designated the SE 95 and SE 143 receivers.” The wavelength range of the CN-208 is 250 to 3100 meters (same as the SE-143).
