§ Mr. Gammans
Eighty-seven short wavelengths and two medium wavelengths are in use. In addition, the B.B.C. uses a Third Programme wavelength and the Light Programme long wave for foreign broadcasts, during periods when they are not required for the home services. The230W Corporation also rents the use of a wavelength at Graz-Dobl in Austria. The total output of overseas broadcasts over these wavelengths is about 400 hours a day.
