Abstract : Over the years in the Department of Physics of the Atmosphere (Moscow University) two-frequency ionsphere stations have been developed for the investigation of drifts, absorption of radio waves, and non-linear effects. The station there at present is for the investigation of drifts of small-scale nonuniformities. A schematic diagram is given of the station consisting of a transmitter and two receivers operating in the range of 1--15 megacycles. The authors discuss the operation of the station and the types of components used. It is pointed out that 35mm film or highly sensitive movie film, Pf-3, are used in the photorecorder system. Mention is made of the fact that since November of 1964 drift investigation at four obtained for the dependence of the direction and the value for the drift rate in the F region for January 28, 1965 at 1405 hours.
