The K5BSA Venturing Crew 73 resource, intended for a ham radio club based in Richardson, Texas, currently presents a 404 "Page Cannot Be Found" error. This status indicates the original content, which likely detailed club activities, membership information, or amateur radio projects, is no longer accessible at the specified URL. The page provides general information about _QSL.net_ hosting services, noting it supports over 30,000 websites for amateur radio operators and organizations. The error message suggests contacting the website owner directly or using an internet search to locate the intended content. It also clarifies that QSL.net cannot assist in finding specific missing pages hosted by individual users, as each site is independently maintained. The platform offers its email and web services without cost to the amateur radio community. Despite the error, the page includes links to general QSL.net resources such as "About QSL.net," "The Help Page," and "EMail Mailing Lists." It also features a prominent "Make a Donation" option, emphasizing that while services are free, user contributions are encouraged to support the hosting infrastructure.

Active antennas can be very useful, in particular they can help reduce local electrical noise by allowing the antenna to be installed in a corner of the garden well away from house wiring. The original PA0RDT antenna uses a very small patch for the antenna and relies on the antenna being installed quite high.

The Boone Area Radio Klub (BARK) serves Boone County, Iowa, as its local amateur radio club, actively welcoming visitors to its meetings and weekly ARES nets. The club maintains a 2-meter repeater on 146.850/250 MHz with a 114.8 Hz tone and a 440 MHz repeater on 443.9+ MHz, both situated at the Boone County Hospital, with a simplex fallback on 146.550 MHz for the 2-meter net. Additionally, BARK supports the Iowa 160-meter ARES net at 1.972.5 MHz, which operates at 9:30 PM on Sundays, featuring a rotating schedule of net controls including KNØR, KBØMPL, NØISU, KEØQEU, and KBØLPI. BARK conducts bimonthly license testing sessions on the second Saturday of even-numbered months, with specific dates like October 19, 2024, at the Hamboree, requiring a $15 fee and prior FCC Registration Number (FRN) acquisition. The club's activities are well-documented through numerous photo galleries from past Field Days (1998, 1999, 2008, 2010, 2013, 2017, 2018, 2019), JOTA events (2013), and special event stations (2010 B&SVRR&M). Members like KBØMPL (Margot Conard) have contributed educational PowerPoint presentations on topics such as "Fun with Handie Talkies," "HF Propagation," and "Digital Mode - FLDIGI - OLIVIA 8/500 - JT65 HF - BAND PLANS." The club's officers, as of May 2018, include WØFS (Clay Conard) as President, NØISU (Mitch Carroll) as Vice-President, and KBØLPI (Eric Sloan) as Treasurer/Secretary, guiding the club's operations and community engagement.

The EA8ALP personal page, hosted on QSL.net, is currently inaccessible, presenting a 404 "Page Cannot Be Found" error. This resource was intended to feature Adelto, an amateur radio operator from the Canary Islands, likely detailing his station, operating activities, or other personal ham radio interests. The QSL.net platform, which hosts over 30,000 amateur radio websites, provides free web and email services to operators and organizations, relying on donations for support. While the specific content of EA8ALP's page is unavailable, the platform's structure suggests it would typically include information relevant to **DXing** and **contesting**, common interests for operators in geographically desirable locations like the Canary Islands. Users encountering this error are advised to contact the website owner directly or use an internet search to locate the intended content, as QSL.net cannot assist with individual site content issues.

The Tri-pole antenna, a clever modification of a standard dipole, allows for dual-band operation by integrating a third element. This design effectively shortens the overall dipole length by 10 to 20 percent, simplifying antenna rotation and offering a compact footprint. KK4OBI's article delves into the operational principles, using a 6 and 10-meter Tri-pole as a primary example, and provides comprehensive instructions for constructing any Tri-pole antenna within the 6 to 15-meter range. Key to the Tri-pole's performance is its off-center feed, necessitating a common mode choke at the feed point for optimal tuning and reduced noise. The author outlines a methodical approach to determining element dimensions, starting with a vertical element frequency calculated as 0.47 times the sum of the desired upper and lower band frequencies. This calculation, along with K-values derived from trend lines, guides the initial lengths for the horizontal arms, demonstrating how a 10m-6m Tri-pole can achieve a total horizontal length 78% shorter than a conventional 10-meter dipole. Tuning and balancing are critical, with the article detailing adjustments to arm lengths and the vertical element to achieve balanced SWR values, as validated through 4NEC2 simulations. Radiation patterns are analyzed at various elevations, showing gains around 5.7 dBi and favorable take-off angles for DX contacts. Construction details specify aluminum tubing dimensions, U-bolts, and an SO-239 connector, emphasizing the importance of a ferrite-based choke for wideband operation.
