The Russian Internet Callbook, hosted at krasnodar.online.ru, offers a specialized lookup service for amateur radio callsigns within the Russian Federation. This online tool is designed to assist DXers and contesters in identifying contact information for Russian stations. The resource functions as a digital callbook, allowing users to search for specific callsigns and retrieve associated data, which is crucial for QSLing and verifying contacts. While the concept is to provide a comprehensive database for Russian amateur radio operators, the current status indicates a configuration issue, as the domain krasnodar.online.ru points to the server but the site itself is not configured. This suggests the service may be inactive or undergoing maintenance, impacting its utility for callsign lookups. The original intent was to serve as a key _DX resource_ for the region. -

Over 47 full-screen maps are available within _NAOMI_ (North American Overlay Mapper), a free Windows program designed for US and Canadian amateur radio enthusiasts. This mapping suite includes 9 backgrounds such as CQ Zones, ITU Zones, and ARRL Sections, along with 16 foreground layers like Counties, Areacodes, and Grid Locators. Users can calculate distances and bearings, track real-time mouse positions with continuous Grid-Locator data, and integrate with APRS for live station tracking via the FindU database. For a global perspective, the _Global Overlay Mapper_ (GOM) provides a world map, 8 continental maps, and 29 sub-continental maps, all with 12 active layers including Country Outlines, CQ/ITU Zones, and Prefix information. Both NAOMI and GOM offer feature-locate systems to jump to positions based on prefixes, capital cities, or Grid Locators, and provide customized beam headings and distance displays. The site also features _LogView_, a post-contest log visualization tool that analyzes Cabrillo-format logs by plotting QSOs on maps, supporting over 30 major contests like CQWW and ARRL DX, and allowing comparison with published results. -
This online article provides a list of individuals who hold or have held amateur radio callsigns, detailing their public recognition. The resource identifies specific callsigns such as **K1JT** (Joe Taylor, Nobel Prize in Physics), **W6OBB** (Art Bell, syndicated radio personality), and **JY1** (King Hussein of Jordan), linking them to their non-amateur achievements. It also notes operational statuses like _Silent Key_ for deceased operators and _lapsed callsign_ for inactive licenses. The article includes information on callsign changes due to vanity callsign programs and provides examples of individuals involved in specific technical areas, such as Percy L. Spencer (**W1GBE**), inventor of the microwave oven, and Jay Kolinsky (**NE2Q**), inventor of electronic sirens. It also references amateur radio involvement in _space missions_ for individuals like Owen Garriot (**W5LFL**) and Helen Sharman (**GB1MIR**).

Beaconmap is a Win95/98/NT program to help listeners to identify the beacon stations of the NCDXF/IARU beacon network. The program displays a flashing dot at the location of the beacon that is currently transmitting. The call sign of the beacon, as well as the QTH is shown in the status bar. By PA1ARE -

At the moment the most used program is UA1AAF. It is an excellent program written by Boris, UA1AAF, to handle ARI International DX Contest. It can simulate K1EA or N6TR workings; it will be possible to connect the RTX to the computer using a standard interface in such a way as to transmit directly in CW from the keyboard; most of the controls are like K1EA's CT and N6TR's TR ; on line help provides almost all the information necessary for using the program. Is possible to insert QSO after the contest. An appropriate utility in included for conversion in ADIF format. The program is very small and therefore works without any problems on any IBM compatible computer with DOS 3.3 and over or Windows 95/98. -

Operating in the Nordic region often requires specific call sign lookup tools, and this resource offers a dedicated search service for Swedish amateur radio operators. Users can query the database by entering a call sign, a family name, or a city, facilitating the identification of hams within Sweden. This functionality is particularly useful for DXers attempting to confirm contacts or for local hams seeking to connect with others in their area, leveraging the official data provided by the Swedish Amateur Radio Society (_SSA_). Such a lookup service streamlines the process of verifying contacts for awards like _DXCC_ or for general QSLing purposes. While many global callbooks exist, a national service like this often provides more granular and up-to-date information for its specific region. The ability to search by city can be especially beneficial for local rag-chewing or for coordinating activities within a specific geographic area, offering a practical complement to broader international databases. -
