Abstract : The recovery of the information originally impressed onto the signal as amplitude modulation which was transferred in phase modulation travelling in the ionosphere is treated. In the first part, the principles are given on which the realized apparatus and that to be realized is based. In the second part the experimental basis of the phenomenon being investigated is discussed. Next the entity of these is theoretically investigated in order to ascertain whether the recovery is practically useful. A detailed description of the tried apparatus and of the results thereby obtained follows. (Author)
