From TV Repairman to EMC Expert: One Engineer’s Persistent Journey

From Hod Carrier to EMC Pioneer: The Unconventional Path of David Weston

The story of David A. Weston is a compelling reminder that a traditional academic path isn’t the only route to expertise, particularly in the complex field of electromagnetic compatibility (EMC). Weston, now 83 and retired, built a distinguished career ensuring electronic devices play nicely together – and without causing interference – after initially being steered away from technical training due to early academic assessments. His journey, detailed in his recently self-published memoir, From a Hod to an Odd EM Wave, began not in a classroom, but carrying building materials on a London construction site.

Weston’s early aptitude for electronics was evident at age 15 when he successfully built an AM radio. Despite this demonstrable skill, teachers and parents doubted his ability to pursue a career as a radio and TV repairman, a profession he found deeply fascinating. This skepticism led him, initially, to manual labor. The experience of physically demanding function quickly convinced him that a trade was a better fit. He ultimately earned a certificate in radio and television from Croydon Technical College (now Croydon College), laying the foundation for a remarkable career.

Understanding Electromagnetic Compatibility

At the heart of Weston’s work lies the principle of electromagnetic compatibility. Simply put, EMC is the ability of electronic devices to function correctly in their electromagnetic environment without causing unacceptable interference to other devices. Electromagnetic interference (EMI), conversely, is unwanted energy that disrupts the operation of electronic equipment. Ensuring EMC is crucial in a world increasingly saturated with wireless signals and electronic devices, from medical equipment to aircraft systems.

Weston’s path to becoming an EMC expert wasn’t direct. After completing his certificate, he worked as a technician for the U.K. Ministry of Aviation, calibrating precision instruments. He then moved to the Medical Research Council, where he designed an electroencephalography (EEG) calibrator – a device used to measure brain activity – and explored using ultrasonic technology to detect brain tumors before the advent of MRI machines. This work demonstrated his ability to apply practical engineering skills to solve complex problems.

From Diving Bells to Space Shuttles

Weston’s career took him from underwater communication systems to the vastness of space. He contributed to the design of a waterproof handheld communication device for divers working in diving bells, and later, to the development of the Canadarm, the robotic arm used on the Space Shuttle. His involvement with the Canadarm specifically focused on the display and control panel, as well as the hand controllers used by astronauts. Throughout these roles, he consistently gravitated towards the challenges of EMC, recognizing its importance in ensuring the reliable operation of critical systems.

A stint at Brookhaven National Laboratory in the late 1970s saw Weston designing a system to detect helium leaks in the Isabelle proton colliding-beam particle accelerator. Though the project was ultimately canceled, the experience further honed his expertise. He later founded EMC Consulting in Arnprior, Ontario, Canada, in 1992, providing EMC analysis, testing, and design services to clients worldwide for over 30 years.

The Value of Practical Experience and IEEE Involvement

Weston’s story underscores the value of practical experience and continuous learning. He holds no academic degrees beyond his vocational certificate, yet he became a respected expert in his field through self-study, on-the-job training, and a commitment to staying current with industry advancements. He credits his long-standing membership in the IEEE Electromagnetic Compatibility Society with providing access to crucial research papers and opportunities for collaboration with other experts, including Life Fellows Lothar O. “Bud” Hoeft, Richard J. Mohr, and Clayton R. Paul.

“Engineering is creative,” Weston says. “To have a new idea or design accepted is rewarding, satisfying, pleasurable, and even exciting.” His memoir, From a Hod to an Odd EM Wave, is intended to inspire others – particularly those who may not fit the traditional mold – to pursue careers in engineering.

Looking Ahead: The Ongoing Importance of EMC

As electronic devices grow increasingly complex and interconnected, the importance of EMC will only continue to grow. The proliferation of 5G networks, the Internet of Things (IoT), and autonomous vehicles all present new challenges for ensuring electromagnetic compatibility. Future work in this field will likely focus on developing more sophisticated modeling and simulation techniques, as well as new materials and designs that minimize EMI. Weston’s career serves as a testament to the enduring relevance of this often-overlooked, yet critical, engineering discipline. His story highlights that innovation and expertise can emerge from unconventional paths, driven by curiosity, persistence, and a dedication to solving real-world problems.
