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.
