This week, we've gathered some practical resources that touch on several facets of our hobby, from getting a handle on software-defined radio setups to optimizing your antenna farm. There's a solid guide for those looking to deploy an OpenWebRX+ station, something that comes up often for remote monitoring or just general experimentation. We also have a look at a popular multiband HF antenna, the ZS6BKW, which continues to be a workhorse for many, especially in constrained spaces. For the low-band enthusiasts, a detailed build for a K9AY loop is included—a receiving antenna worth revisiting for its performance. And for those who like to keep an eye on propagation, a neat WSPR visualization tool is in the mix. These selections aim to provide actionable information for both the home station and portable operator.

Top Amateur Radio Websites - Issue 2643
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.

This week, we’ve pulled together a few items that touch on practical antenna builds and some of the perennial challenges in our hobby. There’s a good look at VHF/UHF Yagi construction, specifically the isolated element method, which can be quite useful for those looking to roll their own directional arrays for local work or satellite passes. We also have a portable 6-meter quad design that might just be the ticket for your next Field Day or VHF contest outing. For the HF crowd, there's a neat take on a 2-band Zeppelin dipole, something that comes up often when space is tight. And, because RFI is always lurking, we’ve included a solid guide on ferrites and baluns, along with a technical deep dive into balun theory and testing. Finally, a handy APRS network visualizer rounds out the selection, offering a different perspective on real-time tracking.
