Dan Lundwall, N7XDL, on Electromagnetic Pulse and Coronal Mass Ejections; What They Are, and How They Affect Us

Our August 15 wpeaker will be Dan Lundwall, N7XDL, who will talk to us via Zoom about solar events that happen millions of miles away but can affect us as hams and in many other ways. His presentations will explain what electromagnetic pulses and coronal mass ejections are, and how these two phenomena — which often are discussed together — differ. Dan will draw on research and analysis done by the military as well as at MIT.
Dan, who last spoke to our club in January, became an amateur radio operator in 2015, and got his General Class license a year later. He enjoys working both VHF/UHF and HF communications, and became interested in emergency communications when he joined the Salt Lake County ARES group.
He looked for a ham radio club in his home town of Murray, Utah, but there wasn’t one, so Dan founded the Murray Amateur Radio Club (https://murrayarc.org) and is now the president. He is also President of UtahSAG, which is a non-profit corporation with the purpose of supporting Amateur (HAM) radio organizations and operators in the state of Utah who provide communications support for charity events.
Dan serves as an Assistant Emergency Coordinator with Salt Lake County ARES, and is the State Emergency Communications Coordinator for his church. He says these activities are based on his awareness of what an earthquake can do (thanks to his experience of a major quake years ago in Chile) and of the possibility that one could hit Salt Lake County at any time.
Dan is a Principal Services Technical Consultant for CA Technologies and generally works in the greater Salt Lake City, Utah area. He specializes in enterprise-wide network management solutions for both the public and private sectors.
