The complex dielectric constant of Rochelle salt crystal has been measured at frequencies from 1.0 GHz to 35.8 GHz in a temperature region from 90 K to 310 K. Dielectric dispersion of the Debye type which shows a critical slowing-down has been observed. Comparison of the present microwave data with the submillimeter data by Volkov et al. (JETP Lett. 41 (1985) 17) reveals coexistence of a soft relaxational mode and an insufficiently softened optical phonon mode at all temperatures. It is conclude based on the present analysis that the phase transition should be driven by the soft relaxational mode.
