 note = {A project is now being carried on of observing radio noises in the ionosphere or the exosphere with the sounding rocket. Up to present, the data from L-2-2, L-3-2, and K-9M-6 were available, though the other two observations were missed due to the damages of the rocket or the telemeter system. In order to measure the value of dispersion of whistlers and the frequency band of hisses two systems were used. The one is a point-frequency system using a whip antenna and several narrow band receivers and the other is a wide-band system using a loop antenna and a wide-band reciver. The whistlers were observed, through both systems and the variation of the dispersion against the altitude has been estimated. On the one hand, a series of strong and periodically varying noises have been observed. Because of their unusual intensity and sharp directivity, it is suggested that the strong noises observed may be caused by the electrostatic ion waves in the plasma.},
