The Buddipole Deluxe, a portable HF/VHF antenna system, receives a practical assessment from IW5EDI after a month of field use. The author, constrained by antenna restrictions, highlights the system's crucial role in enabling portable operations, even managing sporadic digital activity from a balcony. Direct comparisons to a fixed 3-band dipole reveal surprisingly comparable signal reports on 15, 17, and 20 meters, underscoring the Buddipole's effectiveness in real-world scenarios. Tuning the Buddipole proves straightforward on bands down to 20 meters, though the review notes significant challenges with SWR on lower bands like 40 meters, where achieving better than 3:1 SWR was problematic. Observations also include SWR variations with dipole rotation and mast height, suggesting environmental factors play a role. The overall manufacturing quality of the antenna and its accessories, including the tripod and carry bag, is deemed good, despite a minor issue with a pole connector. Looking ahead, the author plans to construct a homemade Buddipole version, possibly optimized for the 30-meter band, specifically for PSK31 operations from an apartment. This personal project reflects a common amateur radio practice of adapting commercial designs for specific needs, further extending the utility of portable antenna concepts.

Linux for shortwave and amateur radio monitoring. Supports popular SDR hardware and online streaming from KiwiSDR, WebSDR, and Spyserver sites. Articles about using Linux with your SDR devices.Skywave Linux, an innovative operating system, leverages cutting-edge technology for seamless access to radio signals globally. Ideal for regions with limited internet access, it effortlessly connects to a network of SDR servers, offering high-performance SDR operation without the need for extensive hardware. With pre-installed and configured SDR software, Skywave Linux simplifies signal discovery and operation for all users.

Several bash scripts are provided to automate common amateur radio tasks on Linux and FreeBSD systems, addressing the need for quick access to specific data without navigating web interfaces. These utilities include `call` for fetching US callsign details from callook.info, `qth` for obtaining address information for US and Canadian callsigns, and `grid` for determining grid squares based on license addresses. Each script is designed for command-line execution, allowing for single lookups or interactive sessions, and emphasizes a KISS (Keep It Simple, Stupid) programming philosophy. Another script, `au_kp.sh`, is tailored for weak signal VHF operators, fetching and displaying the NOAA 30-minute Aurora forecast and GFZ Space Weather Kp index data. This script generates static images, requiring re-execution for updates, and is intended to be run as a clickable desktop object for real-time space weather monitoring. It helps operators track propagation conditions, especially during solar cycle peaks. Beyond bash scripts, the resource offers a PHP/web page `fortune` implementation, including Henrik Aasted Sorensen's PHP script, sample HTML/CSS, and a HOWTO guide for creating fortune files. W3DHJ provides several amateur radio-themed fortune files, such as "Ham Humor & Wisdom" with 354 entries and "VHF Rover Humor & Wisdom" with 223 entries, along with other general humor and wisdom collections. These fortune files are designed with embedded HTML for web page display and are refreshed monthly, offering a total of 21,400 entries.

Accessing this interface provides entry to one of the largest databases for amateur radio voice repeaters, encompassing over 8000 entries from more than 60 countries. The resource supports both desktop and mobile access, with a default display based on browser type, or forced via a "force" parameter (e.g., relais.dl3el.de?force=mobile). Users input a QTH-locator to find local repeater information. The database integrates FM-Funknetz servers and hotspots, potentially creating duplicate entries but ensuring new FM-Funknetz repeaters are immediately displayed. DMR repeater information, including status and talkgroup configurations, is sourced directly from DMR+ / ircDDB and Brandmeister systems, with real-time updates for active and default talkgroups. C4FM/Wires-X installations, particularly MMDVM-based gateways not listed in Yaesu's database, are identified through Brandmeister dashboard descriptions, marked with "W-x" or "W-x#MMDVM" for manual entries. D-Star repeater data from ircddb or QuadNet2 is also incorporated, with entries marked (i), (o), or (d) for manual additions. An APRS interface allows searching by callsign, using Sassan, DL3NCK's database, and offers a mobile-friendly, auto-refreshing display that follows an APRS station. Output data can be generated in GPX format for offline smartphone maps or CSV for spreadsheet applications. The database also attempts to determine valid repeater offsets based on IARU region and frequency, indicated by a "." after the frequency.
