The latest issue of QST magazine features "Solar Cycle 25," signaling an increase in sunspot activity that will improve long-distance ham radio communication for the next seven to eleven years. The hosts contrast this "actual science" with the alarmist rhetoric of climate change, noting that solar cycles have a profound impact on the Earth's atmosphere and radio propagation.

After leaving the touring sound business in the early 1980s, Bob Heil returned to ham radio and found the audio quality of modern Japanese rigs lacking. He developed a small equalizer to improve speech articulation, which won a cover award from QST magazine in 1982. This success led to the founding of Heil Sound's microphone division, which now dominates the global ham radio market.
