Margo Leftin, “September 1974 radio propagation predictions for United States Information Agency Voice of America broadcast coverage, Volume I,” Technical Memorandum OT TM 74 159, U.S. Department of Commerce, Office of Telecommunications, Institute for Telecommunication Sciences, September 1974.
Abstract: HF radio propagation predictions are calculated for Voice of America circuits using the OT/ITS prediction program. Some of the parameter s given are maximum usable frequency (MUF), the optimum traffic frequency (FOT), the lowest useful frequency (LUF), available signal-to-noise ratio (S/N), and circuit reliability.
