Using the example of simple modeling of the unipolar sunspot magnetosphere by the magnetic monopole, submerged in subphotospheric layers, and the temperature, varying with height as hyperbolic tangent, we show the following for cyclotron emission of microwave sources. Given insignificant changes in the intensity of the sunspot magnetic field, which result from oscillations of the sunspot as an entire structure, the amplitude of oscillations of I and V Stocks parameter brightness temperatures at a wavelength of 1.76 cm (NoRH) exceeds that of the magnetic field intensity oscillations by an order of magnitude in percentage terms. At a wavelength of 5.2 cm (SSRT), this amplitude is identical to that of the field oscillations.
