The Department of Commerce, specifically the National Oceanic and Atmospheric Administration (NOAA), is seeking to evaluate, repair, and upgrade four LIMITER, TR, BEVERLY MICROWAVE units, part number BS-2000-320-0000, from the original equipment manufacturer, Communications & Power Industries LLC, located in Beverly, Massachusetts. This procurement is justified as a sole source due to the unique capabilities of the manufacturer, which is the only authorized source for repairs of these specific devices. The TR Limiter is a commercially available item critical for NOAA's operations, and the government does not possess the data rights necessary for alternative repairs. Interested parties can reach out to Adrian Hall at adrian.hall@noaa.gov or by phone at 816-926-3357 for further information.
