To commemorate the 25th anniversary of the September 11, 2001 attacks on the United States, the High-frequency Active Auroral Research Program (HAARP) at the University of Alaska Fairbanks will be making a special transmission on 9.11 MHz at 0030-0035 UTC on September 12, 2026 (8:30-8:35 PM eastern time Friday evening). The transmission will consist of a Morse code QST, followed by a slow-scan ...

ARRL The National Association for Amateur Radio® has announced that the candidates for the 2026 ARRL Division elections are now official. ARRL members will choose between two candidates for Director in the Delta, Great Lakes, and Midwest Divisions, and two candidates for Vice Director in the Midwest Division. The Director positions in the Atlantic and Dakota Divisions are unopposed, as are the ...
Solar activity reached moderate levels this week. Region 4513 was responsible for an M2.2/1B flare that reached its peak on August 26. This event was accompanied by a 10.7-centimeter radio burst that reached 140 solar flux units (SFU) and a type II radio sweep with an estimated shock speed of 930 km/s despite its relatively impulsive nature. No resulting coronal mass ejection (CME) has been obs...
This week, we've pulled together a few items that touch on some persistent challenges and evolving technologies in the shack. There's a practical look at mitigating common-mode issues, something that comes up often when dealing with feed lines and antenna installations, especially for those running higher power or operating portable. We also have a couple of pieces exploring the expanding role of Software Defined Radio, both as a standalone system for advanced modes like Digital Amateur Television and as a valuable companion to traditional transceivers. Finally, a quick nod to the wider RF spectrum with a public safety audio feed, a reminder of the diverse signals out there. It’s a mix that should offer something for those experimenting with RF, optimizing their home station, or even considering satellite operations.
This week, we've pulled together a few items that might spark some interest, particularly for those dabbling in digital modes or looking to refine their station's utility. We're looking at some compact desktop applications that offer a quick glance at propagation and local conditions, something that always comes in handy whether you're chasing DX on HF or just planning a local net. There's also a deeper dive into some hardware for packet and digital radio experimentation, specifically ESP32-based LoRa boards, which are becoming quite popular for everything from APRS to Meshtastic. And for the low-frequency enthusiasts, we found a construction guide for an active loop converter, which could be a real asset for improving reception on the LF band. It’s all about practical enhancements and exploring new facets of the hobby.
This week, we've pulled together a few items that touch on practical aspects of our hobby, from understanding propagation to getting on the air when antenna restrictions are a factor. There's a look at real-time HF conditions using the Reverse Beacon Network, something that comes up often for those chasing DX or just trying to understand band openings. We also have a piece on building a 2-meter skeleton slot Yagi stack, which could be a good project for VHF/UHF enthusiasts looking for something beyond a simple dipole. For those dealing with HOA challenges, there's a discussion on stealth antenna solutions for 40-10m and 80m. And for the digital mode operators, a multi-platform AX.25 terminal program is worth a look. Finally, a historical note on Marconi's early work and a handy ADIF log analyzer round out the selection.
The X-026 finally has a name: Icom has unveiled the IC-7110 at Tokyo Ham Fair 2026, closing four months of teaser campaigns and hamfest mock-ups. Here are the first photos, the confirmed specifications and what the new model means for operators waiting on an IC-7100 successor.
This week, we're looking at a few items that touch on the practicalities of getting on the air and staying there reliably. There's a piece on understanding SSB bandwidth, which is always worth a revisit, especially when operating near band edges. We also have a resource for looking up callsigns, something that comes up often whether you're chasing DX or just curious about a new contact. For those running higher power, or perhaps considering it, there's a useful set of modifications for Ameritron HF amplifiers to help with cooling during those longer digital mode sessions. And, of course, a solid DX cluster tool is always welcome for finding activity. These are the kinds of things that make a difference in day-to-day operation, from the home station to a portable setup.
