%X In this paper the nonlinear shift of the wave number of ion-cyclotron whistlers propagating through the ionosphere in the presence of negative ions is estimated. The results are discussed both numerically and graphically for the proton whistler. It is seen that under some physical situations the nonlinear shift of the wave number of the proton whistler is very significant. Furthermore, the nonlinear shift of the wave number depends significantly on the variation of negative ion concentration when the wave frequency is very close to an ion-cyclotron frequency.
