Abstract The application of a version of the nonlinear plasma theories involving plasma solitons to the corona is investigated. A fairly compact beam is assumed in order to initiate nonlinear plasma phenomena in the corona. The beam's survival is favored by open magnetic fields, and the solitons occur in a front about 1 km thick. The fundamental is emitted at this front and depends strongly on the beam energy through its dependence on the narrow angle of emission. The variability of the fundamental indicates the beam evolution at the beam's front. Observations addressed by the theory include correlations of type III bursts with coronal structure and temperature, the emission of fundamental and harmonic from different source volumes, the polarization of the fundamental, and the starting and disappearance of bursts in the corona, especially type IIIb bursts.
