About rStEngineering.com
RST Engineering is a small, family run business located in Grass Valley, CA. We are the direct descendent of Radio Systems Technology and support the old Radio Systems products that we have documentation for. Jim Weir founded the company in 1973, and after a hiatus when the company was under different ownership, Jim returned a few years ago as the chief RST engineer and bottle-washer. RST Engineering is both a manufacturer and a mail order direct seller via this Web site.
