Aspiring radio amateurs in the United Kingdom preparing for their licensing examinations can utilize this resource, which offers mock exam questions covering the Foundation, Intermediate, and Advanced license levels. The site provides access to question pools, including associated images, designed for use with _Moodle_ learning management systems requiring PHP and MySQL. These question sets are available for non-commercial deployment by UK amateur radio clubs and organizations, facilitating local training initiatives. The original online mock test service ceased operations in August 2018 due to maintenance overhead. The current iteration serves as a repository, allowing other organizations to download the question databases. This approach enables broader access to the exam preparation material, supporting the UK amateur radio community in achieving licensing qualifications. The resource does not offer direct online testing but directs users to other sites, such as _Radio Tutor_, that implement these question banks.

Call Book Log 3.0 is a web-based logging solution for amateur radio operators, designed for self-hosting on a web server with MySQL/MariaDB and PHP 7+ support. It provides a mobile-friendly interface for viewing, adding, editing, deleting, backing up, and restoring QSO logs. The software features a streamlined setup process, allowing users to quickly deploy a personal logging system accessible via any web browser. Key functionalities include displaying the last **5** contact dates for previously worked stations, enhancing log management by providing immediate historical context during QSO entry. The system also includes a central administrative section for authenticated users to manage log entries. The 3.0 version represents a significant code overhaul, focusing on improved performance and a more *visually appealing* user experience compared to earlier iterations. Enhancements include better pagination, a redesigned menu with icons, and color-changing rows for improved readability. The add log page now incorporates a one-click time update feature, addressing user feedback regarding time synchronization during rapid QSO entry. This iteration builds upon previous versions like 2.1, which corrected an automatic _UTC date_ bug, and 2.0, which featured a full rewrite to resolve browser quirks and optimize search functions. The software's evolution demonstrates a commitment to functional stability and user interface refinement.

Presents the Amateur Radio on the International Space Station (ARISS) program, a global educational initiative facilitating direct communication between students and astronauts via amateur radio. It outlines the operational framework for scheduled school contacts, detailing the technical requirements for ground stations and the typical Q&A format used during these events. The program utilizes VHF/UHF frequencies for voice and packet radio communications, enabling students to engage with crew members aboard the ISS. ARISS supports various educational objectives, promoting STEM fields through hands-on radio experience. The resource provides information on how schools can apply for contacts, the selection process, and preparation guidelines. It also covers the history of amateur radio in space, including past missions and the evolution of equipment used on the ISS. Regular updates on contact opportunities, operational status, and technical specifications for ARISS hardware are provided.

The FieldComm Association, based in Central Virginia, operates as a specialized amateur radio club with a primary interest in emergency communications. Members engage in various technical aspects of radio, including digital modes, QRP operations, and DXing. The association provides a platform for hams to develop skills in field deployment and reliable communication under challenging conditions, often leveraging modern digital protocols. This organization's activities support the practical application of amateur radio for public service, emphasizing readiness and operational proficiency. Members collaborate on projects and share knowledge, fostering expertise in areas like portable station setup and efficient data transmission. The focus on emergency communications distinguishes its operational priorities from general interest clubs, aligning its efforts with community preparedness.

Presents the Holy Cluster, a contemporary DX cluster service offering real-time amateur radio spot data. This platform integrates a dynamic graphical map to visualize current contacts, enhancing situational awareness for DXers and contesters. Developed by an Israeli group of developers and supported by the Israeli Association of Radio Communication (IARC), the Holy Cluster aggregates DX spots from various sources, including traditional telnet clusters, the Reverse Beacon Network (RBN), and PSK Reporter, providing a comprehensive view of band activity. The cluster's design emphasizes a user-friendly interface for monitoring DX activity across multiple bands, including dedicated support for JOTA (Jamboree On The Air) operations. Its aggregation capabilities allow operators to quickly identify propagation openings and active stations, streamlining the process of making two-way radio contacts. The integration of RBN and PSK Reporter data offers insights into propagation conditions and station reception reports, which can be invaluable for optimizing antenna direction and operating strategies.

The Amateur Radio Association of Bahrain (ARAB) was established in 1970 to support the amateur radio community within Bahrain, operating under the **A92C** callsign. This organization provided a central point for local hams, fostering activities and representing their interests for several decades. Its historical presence is noted, even though it is no longer active. Unfortunately, due to unforeseen circumstances, ARAB ceased its operations. However, a new amateur radio society has since been formed in Bahrain, continuing the tradition of supporting local hams. Interested individuals can contact Fawaz, **A92AA**, for details regarding membership and the new society's activities, ensuring continued amateur radio presence in the region.
