The articles are written for licensed radio amateurs, beginners preparing for the hobby and technical readers interested in long-distance radio communication.
Radio wave propagation on Earth is influenced not only by terrestrial conditions, but also by the Sun — our closest star. Solar radiation and solar activity can dramatically change how different frequency bands behave, impacting amateur radio, aviation and maritime communications, navigation systems, and disaster communications. In this article, we explore how solar activity (sunspots,…
Artificial intelligence (AI) is rapidly transforming the amateur radio world. What was once driven purely by analog circuitry and operator skill is now increasingly enhanced by machine learning (ML), neural networks, and intelligent digital signal processing (DSP). These technologies are not replacing the operator — they are amplifying capabilities, improving efficiency, and enabling tasks that…

Among radio amateurs and RF experimenters, one question has persisted for decades: is it possible to legally transmit radio signals without a license, purely for experimental purposes?In the United States, the answer is yes — but only within very specific limits. These limits are defined by the Federal Communications Commission (FCC) under the Code of…
At first glance, a microwave oven and a radio transmitter might appear to have a lot in common — both generate high-frequency electromagnetic waves and focus them in a specific direction. It’s no wonder that many radio enthusiasts have wondered: could you actually turn a microwave oven into a working amateur radio transmitter? The answer…
In recent decades, media consumption habits have undergone a radical transformation. The spread of internet usage, digital broadcasting (DAB, DVB), streaming services, and podcasts has significantly reduced the importance of traditional analog broadcasting. This is especially true for longwave (LF) and mediumwave (MW) transmitters, which played a defining role in national and international communication during…
