SRBL is a world-wide network of ground-based instruments providing 24-hour all-weather coverage of solar microwave output. It was designed at Caltech by Gordon Hurford, and will be deployed in 1-2 years as part of the US Air Force's Solar Electro-Optical Network. Each instrument is independently calibrated, and employs a single, automated, 6 foot dish and a frequency-agile receiver observing at 1 to 18 GHz every five seconds. Solar burst spectra follow electron energy distributions and evolution characteristics. Further insight will be gained through comparisons with X-ray and particle observations. Burst locations are determined from the amplitude and phase of spectral modulations. Such information is used in space weather forecasting. The database will be available on the Web. At this Workshop we present spectra and preliminary analyses from recent (1998) prototype archives.
