My data is from the 1984 'Satellite Directory', Phillips Publishing, Bethesda,Md. Make of it what you will. Turner Broadcasting System, Inc. offers Superstation WTBS on transponder 6, Satcom IIIR. CNN is on transponder 14 of the same satellite, CNN Headline News on transponder 15. Transponder 14 also piggybacks the CNN Radio Network. Satcom IIIR is owned by RCA Americom. It was launched in November 1981, and is located over the equator at 131 degrees West longitude. It operates in the C band (transmits at 3.7-4.2 GHz). The transponders have an actual power of 5.5 watts, except for numbers 3,7,11,15,19, and 23 which are 8.5 watts. The beam pattern is centered on Denver. Over a region enclosed by Los Angeles, Houston, Atlanta and Chicago the effective power of the 5.5 W transponders is more than 2500 watts. Over the continental US excepting Texas S of 27 degrees N, Florida panhandle, New England and Eastern New York, the effective power exceeds 2000 watts. In those excluded regions the effective power exceeds 1600 watts. For Anchorage the effective power is 630 watts. For Honolulu it is 355 watts. For those unfamiliar with effective power for radio, it is the power a transmitter which emits uniformly in all directions would have to match the percieved power of a low-power, focussed beam.
