WSJTX-Controller-v2, or Otto, functions as an assistant for the WSJT-X amateur radio program, specifically designed to enhance operational efficiency for weak signal digital modes. The software automates several key tasks, including call management, prioritizing DX stations based on user-defined criteria, and optimizing frequency selection within the WSJT-X interface. It requires a modified version of WSJT-X to function correctly, integrating directly with its core processes to provide augmented control. Otto supports various digital modes, facilitating auto-logging of contacts and generating specific alerts for desired stations or conditions. It is engineered to streamline the workflow for operators engaged in DXing and general weak signal communication, offering features like automatic CQ responses and intelligent band monitoring. The utility is not compatible with certain other amateur radio software and is explicitly noted as unsuitable for contest operations or the WSJT-X Hound mode, indicating its specialized focus on non-contest DX and casual operating. The project's GitHub repository provides the source code and documentation, allowing users to review its implementation and contribute to its development. The software's design emphasizes automation to reduce operator intervention during routine digital mode operations.

The ham radio population is aging, primarily consisting of Baby Boomers and older generations. The author, a spatial demographer, has studied the population dynamics of ham radio enthusiasts, particularly those involved in amateur radio contests. They have published several works on this topic and have written about it in their Social Circuits column, with more writings expected in the future. This document presents a modest analysis of aging and radiosport participation among amateur radio operators, using survey data from the National Contest Journal (NCJ) and two regional ARRL surveys. The results suggest that age is related to contest participation, with older hams tending to engage in more contests per year. However, the author notes the limitations of the data, which are based on voluntary response samples rather than random samples. The paper also examines the sources of contest information used by hams, finding that older contesters favor traditional sources like the NCJ, while younger hams prefer online sources
