Frequency simulation methods are used to investigate the nonlinear dynamics of the cyclotron instability that sets in in the presence of a current flowing in a plasma in a direction perpendicular to the magnetic field. It is shown that ion capture leads to stabilization of the instability. The maximum electric-field amplitude of the excited wave is determined.
