30847 Lampert           Discovered 1991 Sept. 13 by L. D. Schmadel and F. Börngen at Tautenburg.
Klaus Lampert (b. 1943) is a very experienced amateur radio operator whose call sign DK6IP is well known by a lot of friends all over the world. He made confirmed shortwave contacts with operators in all countries of the world. The name was suggested by DK8UH, the first discoverer.
