In 1992,the ITU Conference "WARC 92"allocated the frequency of 2.6 GHz to digital audio broadcasting. When the satellite signal pass through the ionosphere, the reception signals is influenced by irregularities on the ionosphere, whose factor is closely related to the sporadic E layer. As the value of the sporadic E layer electron density is large in the East Japan, we gave it our general consideration based on the results by analysis of ionospheric data in Japan and of our QPS observed data.
