Editorials and Commentary

Never Say Die (Editorial by Wayne Green) Wayne Green's editorial addresses several critical issues facing amateur radio and the broader technological landscape. He argues for a more open-minded scientific approach to phenomena like UFOs, ESP, and memory, criticizing the tendency to dismiss data that doesn't fit current scientific frameworks. Green emphasizes the importance of hobbies like amateur radio in fostering the kind of 'twist of mind' necessary for developing good scientists. He strongly criticizes the DXCC (DX Century Club) award system and the Honor Roll, asserting that they have harmed the hobby by prioritizing QSL card collection over genuine communication and rag-chewing. He recounts his own experiences and those of other readers, highlighting the negative impact on operators in rare countries and the potential for DXpeditioners to exploit the system for financial gain. Green also touches upon the challenges facing American electronics manufacturing, attributing job losses and reduced competitiveness to government debt, high interest rates, and a lack of investment in domestic industries, contrasting this with more supportive environments in countries like Ireland.

Too Much Science? This section reflects on the author's background, blending mechanical and artistic influences, and discusses the perceived overemphasis on science at the expense of other ways of understanding the world. It touches upon the idea that a balance is needed to address complex mysteries.

Recurring Themes and Editorial Stance

The recurring themes in this issue include the practical application of technology in amateur radio, the importance of hands-on projects and experimentation, and a critical examination of the amateur radio hobby's structure and future.
