Radio surveys of northern, close-binary stars in recent years have revealed the RS Canum Venaticorum (RS CVn) stars as an important class of flaring, apparently nonthermal radio sources at centimeter wavelengths. The objectives of the present survey include an initiation of the monitoring of a sample of southern, active-chromosphere objects, and an exploration of the suspected link between variations in the observed radio flux density and the strength of the H-alpha emission from the stars. The results are reported of an eight-day monitoring program carried out using the 5-GHz receiver on a 64-m telescope. A simultaneous four-night H-alpha survey of the radio program stars with a 1.88-m telescope is also discussed.
