The Itchen Valley Amateur Radio Club (IVARC) provides a local hub for radio amateurs in the Southampton and Winchester areas of the UK. This club actively participates in various UK contesting events, including the weekly _RSGB VHF UKAC_ contests, _RSGB AFS club contests_, and _BERU contests_, alongside annual UK field days. As a _Brickworks Accredited_ club, IVARC is committed to supporting both new licensees and experienced operators in exploring diverse aspects of the hobby, fostering skill development and operational experience. Meetings are held on the 2nd and 4th Friday of each month at the Bianchi Suite, Otterbourne Village Hall, offering a consistent schedule for members and visitors. The club's recent activities include supporting _Jamboree On The Air_ (JOTA) for local Scout groups (e.g., GB1ESG), activating special event stations like _GB0SR_ from Solent Rescue Lifeboat Station, and organizing club visits to significant historical sites such as Bletchley Park. IVARC also hosts events like QRP Day and National Field Day, providing practical operating opportunities and fostering camaraderie among members.

Operating in the Caribbean, the Jamaica Amateur Radio Association (JARA) provides a central hub for amateur radio enthusiasts on the island. The association details its **repeater network**, including IRLP node 7673 and ECHOLINK access, alongside information on band activity and packet radio operations. Members can access specific documents like the JARA Membership Form and the JARA Disaster Plan, while general visitors can review the full JARA Regulations and learn about the club's history. The site features a photo album and outlines various radio activities, including what constitutes a JARA Field Day. It also provides essential resources such as the Reciprocal License Form and Jamaica Amateur Radio Regulations, crucial for visiting operators. The **WINLINK Project** and Radio Voice Procedure are also covered, offering practical guidance for communications. JARA maintains affiliations with international bodies like **IARU Region II**, ARRL, and RSGB, and lists important organizations such as SATERN 14.265, Jamaica Red Cross, and the National Hurricane Center. The website also includes links to other amateur radio clubs across North America, the Caribbean, and Central and South America, fostering regional and international connections.

A W8JK/Moxon antenna variant with 400cm long monopoles is detailed, demonstrating a **1dbd** gain improvement over the traditional Open-Folded W8JK. This design, relying on the _Moxon principle_, achieves higher radiation impedance, leading to increased antenna efficiency and reduced losses. The article includes VNA output data for various HF bands, showing impedance characteristics from 10.1 MHz to 50.1 MHz, and provides NEC model wire definitions for the antenna structure. Field tests performed by F6IIV, Marc, compared his W8JK Moxon style antenna against a Cobweb antenna at the same height. Results indicated the W8JK Moxon variant provided a **6dB** (1 S-meter point) advantage on most bands from 20m to 10m, and a significant 10dB (1.5 S-meter points) advantage on 15m. The antenna features a 2.70m boom and a turning radius of less than 3 meters, making it suitable for limited space installations while maintaining bi-directional performance on most bands.

This article provides details on building a 6 Meter J-Pole antenna using PVC pipe for an enclosure. This antenna uses flat 450 ohm Window Line for the tuning stub.

256 memories enable the _AT-AUTO_ to recall settings across multiple bands, making it efficient for operators who frequently change frequencies. The tuner is compatible with various antennas and amplifiers, such as the Mercury LUX, and integrates seamlessly with radios like the FLEX 6400 using an RS232-USB connection. This integration allows the tuner to follow frequency changes without additional input, enhancing operational efficiency. Despite being out of production, the _AT-AUTO_ remains supported by Kessler Engineering, which offers firmware updates and repair services. The tuner features a cross-needle SWR meter, providing quick visual feedback during tuning. It also includes a QRO keyline circuit to protect amplifiers during tuning. Users appreciate the tuner's ability to track radios via CAT control, avoiding automatic tuning during QSOs, a common issue with other models. The _AT-AUTO_ is praised for its durability and performance, with many users noting its reliability over years of use. Its ability to handle legal limit power and its balanced line output make it a versatile choice for serious operators. Although it lacks some features like multiple coax outputs found in other models, its robust build and continued support make it a valuable tool for HF enthusiasts.

Details the history and cessation of the Amateur Radio Association of Bahrain (ARAB), operating under the callsign **A92C**. Established in 1970, ARAB functioned as the primary representative body for amateur radio enthusiasts within Bahrain for several decades. The organization facilitated various amateur radio activities and provided a central point of contact for local hams. The resource indicates that ARAB ceased operations due to unspecified circumstances. It explicitly states that the organization is no longer active, marking the end of its long-standing service to the Bahraini amateur radio community. Information regarding a newly formed society, open for membership, is provided, with contact details for Fawaz, **A92AA**, for further inquiries about the successor organization.

The collinear J-Pole, often known as the Super-J, does improve the behavior over a regular J-Pole. there is an advantage when vertically combining 1/2 radiating sections to have a bit of separation between the half-wave end points. Get 0.8 dB more gain out of the trusty Super-J by replacing the traditional phasing stub with a long coil.

A hexagonal beam is a form of the Yagi antenna which is based on parasitic principles developed early in the last century in Japan for achieving gain in one direction.How HexBeam antennas works. A hexagonal beam operates exactly like Yagi antenna, but instead of a driven element that is straight like a dipole, it is a wire bent into the shape of the letter M.
