EMC Consulting
Keith Armstrong graduated in 1972 from Imperial College, London, specializing in electronic design and field theory. After working in several countries, he joined the first pro-audio custom-mixing-desk manufacturer to use digital audio. Five years of intense work resulted in the ability to design the lowest-noise A-D convertors correct at the first iteration, with the most sensitive analog and digital circuits on the same ground plane. Later, Keith added switching power converters to his ‘right first time’ approach.
When manufacturers began testing to the EMC Directive, those using Keith’s approach found tests easy to pass. This became the basis of his independent company, started in 1990: Cherry Clough Consultants (after his house – a “Cherry Clough” being Norwegian Viking for a valley with cherry trees).
Enough of Cherry Clough’s 800+ satisfied customers worldwide have adopted Keith’s “Good EM Engineering” approach that it is well-proven to be cost-effective in all applications, with even the toughest EMC standards, up to 24GHz (so far!).
Since 1987 Keith’s Working Groups have created the brand-new discipline of managing the functional safety risks caused by EMI. This is hugely important for future safety, most especially for autonomous vehicles.

EMC Chambers
Bruce Alexander is the President of Raymond EMC. His start in the industry was back in ’92 as an installer with Rayproof Canada. When Raymond EMC was established in ’94, he started testing and a little later on he started an install company. In 2012 he purchased Raymond EMC.
Back then, the bulk of Raymond EMC’s work was in Tempest shielding, but over the last few years the company has become well known as an excellent supplier of EMC chambers. “It’s really been our approach to client care and customer service that had propelled our recent growth”, says Bruce. And the company has grown exponentially in the last few years!
Raymond EMC’s core values of excellence, adaptability, integrity and fun are really a reflection of Bruce and the team he has put together. “Our core values are really what drive us”, says Bruce, “and those values are lived out in the way we deal with not only our clients, but also our supply chain and internally with our team as well.”
Bruce likes to spend his spare time at home or at the cottage with his family. He likes skiing in the winter and waterskiing in the summer. He is also actively involved in hockey as a coach and a player.

EMC Training
Daryl Gerke (PE) is the surviving partner of Kimmel Gerke Associates, an engineering consulting firm specializing in EMC. In full time EMC practice since 1987, Daryl and his late business partner Bill Kimmel (PE) solved or prevented hundreds of EMC problems in a wide range of industries – computers, medical, military, avionics, industrial controls, vehicular electronics and more.
Daryl got started in EMC creating interference as a teen age radio ham. His passion for radios led to a BSEE (University of Nebraska – 1968) and his first job with Collins Radio. Having radio on his resume twice led to EMC /TEMPEST/EMP in 1970 with Univac Defense Systems, and he has been involved with EMC ever since.
While at Univac, Daryl led a one year classified research project to EMP harden the UYK-20 Navy standard minicomputer, along with classified TEMPEST projects.
In 1978, he and colleague Bill Kimmel began moonlighting, which led to full time EMC consulting in 1987. Daryl also authored or co-authored three books, a 20 year newsletter, and over 200 technical articles on EMC. He and Bill trained 12,000+ students through their public and in-house courses. No longer consulting, Daryl remains active in EMC training.
