The RBN S-Meter visualizes real-time HF propagation data from the Reverse Beacon Network (RBN). It processes thousands of automated spots per hour, providing a real-time picture of active RF paths on HF bands. Users can set their vantage point using _Region Mode_ or _Grid Square Mode_. Region Mode allows selection from broad geographic areas like E. North America or Europe, while Grid Square Mode uses a Maidenhead grid square and radius for more precise data. The app displays eight region panels, each with horizontal bars for bands 160m through 6m, indicating signal strength with a color ramp from green to red. A dimmer trail shows peak hold values, and an S-unit readout provides additional detail. The app is a free web application accessible on any device, offering a practical tool for ham radio operators interested in CW, RTTY, and FT8 signals. It features a Progressive Web App installation option for enhanced usability on mobile and desktop platforms. Users can install it on Android, iOS, and Windows devices, providing a native app-like experience. The app replaces the previous Windows standalone executable, incorporating user feedback to improve features like grid square mode and automatic location detection.

With Varying Frequency - Amateur Radio Ponderings

The **LDG Z100 Autotuner** review by GW6ITJ details the unit's practical application and performance in a ham shack environment. Initially acquired to replace an MFJ-902, the Z100 is noted for its ease of use, though the author observes it doesn't quite match the impedance range of the older MFJ unit. This hands-on assessment provides a real-world perspective on its capabilities for 100-watt operation across the HF bands. GW6ITJ specifically mentions the Z100's suitability for 3.5 MHz and higher frequencies, indicating its utility for common HF operations. The review focuses on user experience rather than technical specifications, directing readers to the LDG website for detailed data and manuals. This approach highlights the tuner's operational characteristics from a user's perspective. The author's experience with the Z100 suggests it's a reliable choice for general amateur radio use, particularly for those seeking a straightforward autotuner. The comparison to the MFJ-902 offers a valuable benchmark for hams considering a similar upgrade or new acquisition, emphasizing practical differences in impedance matching.

Presents the construction of a shortened _Morgain_ dual-band wire antenna for 40 and 80 meters, specifically designed for installations with limited physical space. The design achieves a compact footprint of approximately 10 x 0.5 meters, utilizing 64 meters of 1.5 mm² insulated electrical wire. The article details an alternative configuration that reduces the antenna's physical length while maintaining its electrical characteristics for dual-band operation. Author _Remo - IM0JZJ_ conducted tests from Sant'Antioco, Sardinia, reporting SWR measurements of 1.2:1 to 1.4:1 on 40 meters. On 80 meters, SWR ranged from 1.1:1 to 1.5:1 across 3620 kHz to 3720 kHz, with a 1:1 current balun recommended for coaxial feed due to the antenna's approximately 50-ohm feed-point impedance. The installation used two 11.50-meter galvanized steel poles, supporting the antenna at about 10 meters above ground. Construction involves three wooden boards and sixteen fiberglass laminate spacers, with specific instructions for routing the 32-meter wire arms. The design eliminates jumpers for 40-meter tuning but requires two jumpers approximately 1.45 meters from the ends for 80-meter operation, which are tuned and then permanently soldered.

Each key translates Morse code into English and CW prosigns in real time as you practice. Practice sending Morse code with a straight key oscillator. Settings include WPM, show/hide Morse code/text, choose sidetone 400Hz-800Hz. Adjust the WPM so that you can produce well formed DITs and DAHs at a comfortable speed.

The International Lighthouse/Lightship Weekend (ILLW) is an annual amateur radio operating event, typically held on the third full weekend in August, spanning **48 hours**. Originating in 1998 as the _Scottish Northern Lights Award_ by the Ayr Amateur Radio Group, the ILLW has evolved into a major international event. It encourages amateur radio operators to activate stations from lighthouses and lightships worldwide, fostering contacts and promoting maritime heritage. The event is characterized by its minimal rules, making it accessible and enjoyable for participants without the competitive pressure of traditional contests. Over 500 lighthouse entries from more than **40 countries** participate annually, contributing to August becoming recognized as "Lighthouse Month" within the amateur radio community. Unlike typical contests, the ILLW emphasizes participation and enjoyment over scoring or prizes for high contact counts. The site provides registration forms, entrant lists for upcoming years like 2026 and 2027, and reports from previous events, alongside historical context for the ILLW and related lighthouse activities such as the US National Lighthouse Week and the International Lighthouse Heritage Weekend.

This DIY vertical multi-band Windom antenna offers a practical and effective solution for amateur radio enthusiasts seeking a versatile and compact antenna for HF communications. Its simplicity of construction, multi-band capability, and favorable performance make it a valuable addition to any radio shack. The article provides detailed instructions on constructing the antenna and balun, along with diagrams and component specifications. Field tests demonstrated successful contacts with stations across Europe and North America on 14, 18, and 28 MHz. The antenna exhibited comparable performance to a W3DZZ dipole and outperformed a Cobweb antenna on 18 MHz. Low noise levels were observed, effectively suppressing background noise.

DX Maps provides a specialized map printing service, focusing on amateur radio applications such as world prefix maps and custom great circle projections.
