Experimental and theoretical investigation of whistler waves produced in the interaction of a density modulated electron beam with a magnetized plasma are presented for the conditions of active space experiments in the Earth ionosphere as well as for the case of overdense laboratory plasmas. Structures of the electromagnetic fields far and near the beam, efficiency of the beam modulation, emitted power are examined as well as conditions for an undistorted registration of the whistler signals by remote receivers in space.
