Operating an **Echolink** gateway on the 4-meter band presents unique opportunities for extending VHF communications, as demonstrated by the EI4FMG node. Situated at Fieldstown, Monasterboice, this gateway provides coverage across a significant portion of Ireland's east coast, leveraging a Tait TM8100 radio and an EI4JR Echolink interface logic. My own experience with similar setups confirms the importance of strategic site selection for maximizing reach, particularly with a 122-meter elevation above sea level. Access to the EI4FMG gateway, identified by node 57006, requires a **CTCSS** tone of 88.5 Hz, a standard practice for managing access and minimizing interference on shared frequencies. The system transmits with 15 watts of power and utilizes a Sigma CAT70 @5MAGL antenna, a configuration well-suited for regional VHF coverage. The gateway also features an auto-ID every 8 minutes, ensuring compliance and clear station identification. Users can interact with the gateway using various DTMF commands, allowing for connections to specific nodes, random repeater/link or conference nodes, and managing disconnections. These functionalities streamline the process of linking into the broader Echolink network, enabling local VHF operators to communicate globally through the internet backbone.

Presents the 4th edition of the IARU Region 1 Ethics and Operating Procedures for the Radio Amateur, a fully rewritten guide published in July 2026. It establishes a shared basis for respectful and effective communication within the amateur radio community, building upon over fifteen years of prior work. The document details the purposes of amateur radio, principles of non-interference, electromagnetic compatibility, and station safety. It specifies operating procedures, including listening practices, adherence to IARU and national band plans, appropriate transmission content, use of Q-codes, and the phonetic alphabet. The guide provides instructions for conducting QSOs across phone, CW, and various digital modes. Specific sections address managing pileups, participating in contesting, engaging in DX and DXpedition operations, operating portable or mobile, and conducting station testing. Further sections cover VHF and UHF operating considerations, ensuring a comprehensive resource for both experienced operators and those new to the hobby.

The ON4RSX website serves as the official online presence for the UBA Ronse/Renaix amateur radio club, providing information on its community and activities. It outlines the club's engagement across various amateur radio facets, including **HF**, VHF, UHF, digital modes, antenna construction, propagation studies, and general electronics. The site highlights past DXpeditions, such as the _OJ0V Market Reef_ operation, and mentions participation in contests, offering insights into the club's operational focus and technical interests. The resource details the club's commitment to fostering a welcoming environment for operators of all experience levels, from beginners to seasoned technicians. It implicitly compares the breadth of activities available to members, covering both theoretical knowledge development and practical application in areas like antenna building. The site's content structure suggests it functions as a central hub for club news, event announcements, and potentially educational materials, supporting members in expanding their radio knowledge and sharing their passion.
