The report describes investigations on ATS-F receiver design and applications of electron content to propagation problems. The planned ATS-F satellite will transmit radio signals at several frequencies with associated modulations. These transmissions will enable experimenters to perform several measurements. These are Faraday rotation, dispersive Doppler and dispersive group delay. Based on design considerations a portion of the phase-lock receiver has been built and tested. The receiver seems to meet all requirements on both Faraday rotation and dispersive group delay measurements. Two propagation problems have been investigated. The first is concerned with the relation between the maximum usable frequency and electron content. The second is concerned with the effects of horizontal gradients on elevation angle and azimuthal angle of arrival of a radio signal. Author
