I write a digital modes technical column for The Canadian Amateur (TCA), the national publication of Radio Amateurs of Canada (RAC), and will upload supplementary articles and/or software with each column's references and resources, but the column text (usually revised and/or updated) is only posted on my website one year after first publication in TCA.
