Abstract: The results of observations of several systems are presented for the 0.327-90 GHz range to study the radio coronae and outbursts associated with the RS CVn stars, as well as their visibility at millimeter wavelengths. The radio spectra are observed with the VLA and the Nobeyama 45-m millimeter-wavelength telescope. The three stars observed with the Nobeyama and VLA telescopes are UX Ari, AR Lac, and HR 5110, and the frequencies and conditions of the nonsimultaneous observations are set forth. Observations of the RS CVn systems at mm wavelengths is possible, and it is theorized that important information regarding flares and energy release can be derived from these data. A simple model is presented for the radio-coronae source related to outbursts of up to 5 GHz, and the onset of outbursts are predicted to be accompanied by low frequency type-II plasma emission.
