This week’s collection brings forward some interesting projects and analyses, particularly for those operating on the lower bands or experimenting with specialized arrays. We’ve got a detailed look at an 80-meter antenna design, something that comes up often when trying to optimize for that band without a massive footprint. For the builders, there’s a balanced ATU project that emphasizes safety and effective matching, a critical aspect for any home station. Also included is a simple yet effective RF probe, useful for tracking down stray RF, which can plague even well-designed setups. We also touch on packet radio, an often-overlooked mode that still offers robust communication, and a serious EME array for those pushing the limits of VHF/UHF. Finally, a piece on contesting strategy, always worth revisiting for new and seasoned operators alike.
The Folded Trifilar Antenna for 80M Band – Analysis details the design and modeling of a compact 80-meter antenna. It guides the reader through calculating resonance and adjusting dimensions, making it useful for hams with limited space.
The Balanced Antenna Tuning Unit Construction – Creative Science Centre provides instructions for building a balanced ATU. This project focuses on safety through ground isolation and is suitable for operators needing a versatile tuner for 20 to 10 meters.
The LED RF V-Probe for Radio Amateurs describes a DIY RF probe design. This tool offers improved sensitivity over older methods for detecting unwanted RF on grounds and chassis, aiding in station troubleshooting.
The FARPN Federated Amateur Radio Packet Network wiki serves as a central resource for packet radio enthusiasts. It offers documentation and tools for navigating and utilizing the network, benefiting both new and experienced packet users.
The Dual 9-Element 2.5 Lambda
EME Yagi Array outlines the construction of a high-performance
EME antenna system. This project is for advanced experimenters looking to build a robust array with rotatable polarity for moonbounce operations.
Contesting 101: Importance of Calling CQ | OnAllBands features Kirk Pickering, K4RO, discussing the strategic importance of calling CQ in contests. It offers insights for contest operators, especially newcomers, on developing essential operating skills beyond spotting assistance.
