The problem of the presence of high-frequency oscillations in lower hybrid cavities in the plasma of the earth's ionosphere is considered. It is assumed that the oscillations in the cavity are excited due to the ring ion current across the magnetic field, in addition to the mechanism of the Hall current arising from the radial inhomogeneity of the plasma density. The radial dependence of the density of the ring ion beam is also taken into account.
