Latest Prediction: Long Solar Minimum An international panel of space scientists is predicting a long, deep, solar minimum, followed by a Cycle 25 they expect to be similar to the now-ending Cycle 24.’s Dr. Tony Phillips says the group, which met in early April at the National Oceanic and Atmospheric Administration’s (NOAA’s) annual Space Weather Workshop, expects the current cycle to bottom out sometime between this July and next September, with a slow climb out of the basement toward a weak peak between 2023 and 2026. On the other hand, says the group, there are no indications that we are headed for a repeat of the 17th-century Maunder minimum. The solar minimum will be weak, says Phillips, but not that weak. A more refined forecast is expected later this year. ARRL…

zero bias: a cq editorial

I’m writing this while sitting in an airport boarding “lounge,” waiting for a flight that’s been delayed by two hours due to maintenance working on “an issue in the flight control deck” (and the plane isn’t even a 737 Max!). The reason I’m mentioning this is because the airline on which I’m (hopefully) flying bills itself as the home of the “friendly skies.” And having this extra time got me to thinking about ham radio as the home of the “friendly skywaves.” Sure, there are those among us who don’t meet that qualification, and sometimes they stand out from the crowd. But that’s the whole point. “The crowd,” the vast majority of hams are friendly and extremely generous with their time, knowledge, and even equipment. This even applies to competitors, as…

2019 Hamvention Award Winners Announced The Dayton Amateur Radio Association has announced the winners of the 2019 Hamvention® Awards, considered among the most prestigious recognitions in amateur radio. This year’s Amateur of the Year is HamSCI founder and coordinator Nathaniel Frissell, W2NAF. HamSCI (Ham Radio Science Citizen Investigation) is a program designed to build long-term relationships between amateur radio operators, acting as citizen scientists, and professional researchers in the fields of propagation and space science. The hams can provide hundreds or thousands of data collection points while the scientists can use that data to learn more about phenomena related to radio wave propagation. Frissell also organized the 2017 Solar Eclipse QSO Party. He has written several articles for CQ. Dayton’s Technical Achievement award this year goes to telegraph key designer and manufacturer Piero…

contesting from siberia: cq world wide cw at rwøa

Every ham radio competitor knows the feeling: Excitement, camaraderie, and sleep deprivation. Here we go again. It’s time for another CQ World Wide DX contest. I am privileged to participate at a station with very large towers and antennas, multiple operating positions, and good friends. Being in a rare CQ zone also doesn’t hurt. Journey to RWØA For me, the CQ World Wide contest weekend begins on Friday morning at the railway station. I must travel by train for 12+ hours to reach RWØA before I make the first QSO. Once there I will be among friends, and together we will compete in the multi-multi category of the CQ World Wide CW Contest. For the 2018 contest, I began as usual with the long ride on the Trans-Siberian Railway. The railway is popular…
