Those were all fairly common shortwave band designations for Canadian made radios on the range switch. The dial itself would have both the frequencies and the wavelengths marked for each band with the frequencies in larger print. Unlike the U.S, the shortwave craze seems to have held on longer in Canada, even many post war sets up until the early 50s have multiple bands.
