TL;DR: In this article, it was shown that long-distance propagation paths may be sustained either by hop modes in the presence of irregularities in the ionosphere or by ionospheric dueling.
Abstract: Signals transmitted by satellite ORBIS at 10.004 Mc/s were received at Haringhata Field Station (geomagnetic lat. 12°15’ N, geomagnetic long. 32° W). Long-distance propagation paths could be established between the station and the satellite in some passes, while a few overhead passes could not be received. Absence of signals from a few overhead passes is explained in terms of blanketing-type sporadic E. It is concluded that long-distance propagation paths may be sustained either by hop modes in the presence of irregularities in the ionosphere or by ionospheric dueling.
