worldradiohistory.com: Broadcast listening in the pioneer days of radio on the short waves, 1923 1945 Jerome S. Berg Citat: "...The 1930s also saw the inception of FM broadcasting in the shortwave bands. As today, FM signals were free from static, and of higher fidelity. In the early 1940s, before being allocated their present frequency range of 88-108 mc. (in 1944), FM stations operated in the 42-50 mc. band. Before that, in the mid to late 1930s, these stations were allowed to experiment on 11 meters, or 25-27 mc. (the "apex" band as it was called). Many stations became active in this band. W9XTC, Minneapolis, simulcasted WTCN -1250 on 26050 kc; W6XKG transmitted from Los Angeles on 25950 kc. 24 hours a day; and WOR's 100 watt shortwave outlet, W2XJI, on 26300 kc., carried a program for the NNRC on Tuesday and Friday nights...", backup
