Amateur Television (ATV) operations involve transmitting and receiving live or recorded video and audio signals over amateur radio frequencies. Unlike narrow-band modes, ATV utilizes a wider bandwidth to convey video information, often requiring specialized transceivers, antennas, and signal processing equipment. This mode allows hams to share visual content, demonstrate projects, or conduct video conferences, typically on VHF, UHF, and microwave bands due to the bandwidth requirements. The SwissATV resource focuses on the technical aspects and community engagement surrounding ATV within Switzerland. It covers topics relevant to setting up ATV stations, understanding signal propagation at higher frequencies, and participating in local ATV activities. The site serves as a central point for Swiss ATV operators to exchange knowledge and coordinate transmissions, fostering the growth of this specialized amateur radio mode.

The Eastman Amateur Radio Club (VE4TG) operates a **VHF repeater** at 146.73 MHz and a **UHF repeater** at 444.15 MHz, both located at the Manitoba Hydro gas-fired generating station near Selkirk. These repeaters are situated on the power plant roof, leveraging its infrastructure for antenna placement. The club's primary objective is to offer a reliable local repeater site for members in the East Selkirk and Lockport areas, ensuring consistent amateur radio access. Beyond routine communication, the club maintains a standby communications link to assist local municipal authorities during emergencies requiring communications support. The unique repeater site location at a generating station provides a robust backup power supply, enhancing reliability. The club also organizes activities such as a weekly net and participates in WARC Field Day, fostering community engagement and operational readiness.

Approximately 524,475 Brazilian amateur radio operators are cataloged within this resource, offering a comprehensive database for the South American region. Each entry includes geographical coordinates, enabling users to visualize station locations directly within Google Earth. This functionality supports DXers in identifying potential contacts and understanding propagation paths relative to specific Brazilian QTHs. The platform serves as a digital callbook, primarily focused on the Brazilian amateur radio community. It facilitates the lookup of callsigns and associated location data, which is crucial for award tracking, contest planning, and general operational awareness. The integration with mapping services provides a visual dimension to traditional callsign databases, enhancing the utility for operators interested in geographical aspects of radio communication.

The P4 Aruba Callbook, last updated in 2010, serves as a directory for amateur radio operators active from the Caribbean island of Aruba. It meticulously categorizes P4 callsigns into several types: **P41-** for special resident calls valid for one month, **P43-** for permanent resident calls renewable annually, **P49-** for permanent visitor calls also renewable annually, and **P40-** for temporary visitor calls valid for one month, often used in contests. The resource notes that obtaining a permanent visitor callsign requires passing a local examination. The callbook lists numerous specific callsigns, including their QSL routes, operator names, and sometimes addresses or activation dates. For instance, P41A routes via P43A, and P40HQ was used by P43ARC via I2MQP for IARU contests. The entries include both active and Silent Key (SK) operators, with dates of passing where known, such as P43ADA (SK, Sep 2014) and P43JB (SK Jan 2012). This detailed listing assists DXers and contesters in verifying contacts and ensuring proper QSLing for Aruba operations.

The original SurplusEQ.com domain, once a hub for amateur radio operators and electronics enthusiasts seeking test equipment, meters, and various high-tech components, has been repurposed. Historically, such platforms facilitated the acquisition of essential gear for shack setups, antenna analysis, and general electronics work, often providing cost-effective alternatives to new retail purchases. The site's previous focus on "test equipment, meters, testers" directly supported the technical aspects of the hobby, from RF measurements to circuit diagnostics. Currently, the domain points to a gambling platform named "SEMUTWIN," offering online slot games, live casino options, and other digital wagering activities. This shift represents a complete departure from its former identity as a resource for surplus electronics and amateur radio-related equipment. The content now features game titles like "Sweet Bonanza Super Scatter" and "Gates of Olympus Super Scatter," alongside promotional offers for online gaming.
