Dr. Ulrich L. Rohde, N1UL, was honored recently by the Institute of Electrical and Electronics Engineers (IEEE) as the recipient of its 2022 Photonics Society Engineering Achievement Award. A partner in Rohde & Schwarz, a manufacturer of a variety of high-end communications and test/measurement products, he has been an active ham since being licensed in 1956, according to the ARRL Letter. The Photonics Society award recognizes outstanding achievement in the field of optoelectronic signal generation and optical measurement equipment.

Richard “Dick” Ehrhorn, W4EA, a pioneer in magnetic resonance imaging technology and a major player in the amateur radio manufacturing world of the 1960s and ’70s, became a Silent Key in late June at age 88, the ARRL Letter reported. Best known for designing RF amplifiers, Ehrhorn founded Signal One and Ehrhorn Technological Operations (ETO), and was chairman of Alpha/Power, Inc. He later applied his expertise in amplifier design at General Electric, designing an RF amplifier to work with its then-new MRI systems.

Retired CBS engineer and senior vice president Bob Ross, N2OML, also became a Silent Key in June. Ross worked in broadcast engineering for over 45 years, according to an announcement in “TV Tech,” and served as CBS’s Senior Vice President of East Coast Operations from 1998 to 2017. A member of the Broadcasting and Cable Hall of Fame and recipient of a Lifetime Achievement Emmy Award, Bob could often be found searching for bargains at the Dayton flea market. He had moved to Arizona after retirement.
