Abstract: HF radio propagation predictions are calculated for Voice of America circuits using the OT/ITS prediction program. Some of the parameters given are maximum usable frequency (MUF), the optimum traffic fre­quency (FOT), the lowest useful frequency (LUF), available signal-to-­noise ratio (SIN), and circuit reliability.
