The active sunspot region that has been giving us improvedpropagation over the past several days will be rotating awayfrom Earth’s view today, but conditions on most of the HFamateur bands should remain pretty decent in the days ahead,as the 10.7-centimeter radio flux remains right around 100.However, NOAA’s Space Weather Prediction Center (SWPC) saysthe geomagnetic field could become unsettled...

Look for improved propagation on the upper HF bands, as both thesunspot numbers and 10.7-centimeter radio flux remain near or above100. According to NOAA's Space Weather Prediction Center (SWPC),the increase in activity is being fueled primarily by sunspotRegion 4551, which is described as the largest and most complex ofsix sunspot regions currently visible on the surface of the Sun.Mostly quie...

This week, we’ve pulled together a few items that touch on some perennial topics for the active amateur. There's a solid primer on antenna fundamentals, something that always bears revisiting, especially when troubleshooting a new portable setup or optimizing a home station. We also look at a couple of interesting software solutions, one for weak signal modes that runs right in your browser, and another that aims to be an all-in-one station control. For those operating in urban environments, we’ve included a piece on low-band receiving antennas, which can make a significant difference in pulling out those faint signals. And for the emergency communications folks, there's a detailed look at ARES/NIMS integration. Finally, a real-time satellite tracker rounds out the selection, useful for anyone chasing LEO birds.
