Abstract The nonlinear response of the equatorial current jet to external actions is considered, as well as some geophysical effects produced by it. Irradiating the current jet by short-wave electromagnetic radiation with amplitude modulation in ranges of VLF emission and geomagnetic pulsations, one can provide for conditions when a nonlinear antenna is realized in the current jet region. Estimations have shown that under the current jet on the ground surface electromagnetic signals on modulation frequencies can be two orders of magnitude larger than at middle latitudes due to modulated electron temperature and density. The effect of signals from the modulated equatorial current jet on the modes of operation of the plasma magnetospheric maser in VLF waveband is considered. The resonance modification of the spectra of natural electromagnetic waves of VLF range in the magnetosphere is shown to be possible.
