Abstract : Propagation data from a stepped, high-frequency oblique sounding receiver were correlated with X-ray flux data from the SOLRAD IX satellite to investigate solar X-ray bursts and resultant short wave fade (SWF) phenomena. The areas of primary interest were the disruptive effects observed by the communicator operating in the 3- to 30-MHz frequency range. Parameters studied include frequency blackout and recovery duration as a function of X-ray flux magnitude and frequency vulnerability to SWF. (Author)
