On the example of the hot Jupiter HD 189733b, in whose magnetosphere the conditions for the 'operation' of an electron-cyclotron maser are not fulfilled, an analysis of the plasma mechanism of radio emission generation is carried out. The purpose of the analysis is to highlight the range of parameters at which the realization of a plasma maser is possible, as well as to determine the frequency range of generated radio emission. The conditions under which the plasma maser is efficient enough to generate radiation with the intensity accessible for observation by the existing radio telescopes are also defined.
