I wrote a technical column for The Canadian Amateur (TCA), the national publication of Radio Amateurs of Canada (RAC), from 2012 to 2026 (75 articles). Here are the uploaded supplementary articles and software, along with each article's references and resources, as well as the revised versions of those articles. All new ones starting with article 76 will still carry my Radio Magic banner, but they will be only published here first, and on my schedule. Eductators and non-commmercial use websites and periodicals are free to use or rerepublish any of them without asking for permission, so long as they are credited as my original work(s) and their content aren't changed.
