The report is one volume in a set known as the Intermediate and Short Distance Sky-Wave Propagation Charts. These charts show the upper and lower limiting frequencies for radio communication in the 2 to 30 MHz band for distances up to 2400 km. Predicted values of frequencies are shown for the solar activity extremes for a normal solar cycle i.e., sunspot numbers of 10 and 110. Values of frequency predictions may be obtained for any time during the normal solar cycle by means of interpolation. These charts will be applicable at least through calendar-year 1976. Within each volume, the predictions are given for six seasonal intervals--January-February, March-April, May-June, July-August, September-October, and November-December. Within each seasonal interval, the predictions are given in a series of 22 charts. Modified author abstract
