Observed and predicted HF propagation data are compared. Observed data were taken by obliqueincidence ionospheric sounders, the Philips sounder November 1961 and February 1962 and the Granger Associates sounder 1963, operated between Fort Monmouth, New Jersey and Palo Alto, California. Predictions were taken from the HF propagation prediction program written by Stanford Research Institute for use on the IBM 7090 computer. The comparison was undertaken in order to find how well the computer prediction methods predict skywave propagation and where these methods can be improved. Author
