Over 100 FCC districts are analyzed by this resource, providing a predictive database for amateur radio vanity callsign assignments. The system simulates the FCC's application process, calculating the probability of assignment for specific callsigns, such as KD3Q at 94% or N9QC at 97.8%. Data is meticulously organized by FCC district, detailing available, pending, and upcoming callsigns, alongside those currently blocked by renewal or other FCC administrative actions. This allows hams to gauge their chances of securing a desired callsign. The database presents specific application entries, including the date entered, receipt date, process date, the applicant's current callsign, and the vanity callsigns they have applied for. Each entry facilitates examination of predicted outcomes, which categorize potential assignments as assigned, competitive, non-assigned, unneeded, curable, or unknown status. For instance, an application for K7DM clearly shows multiple applicants, indicating a highly competitive assignment scenario. This tool is particularly useful for those seeking a **short callsign** or a **1x2, 2x1, 2x2, 1x3, 2x3, 3x1, 3x2, or 3x3 callsign** that aligns with personal preferences or contest aspirations. It provides a clear, data-driven perspective on the likelihood of obtaining a specific vanity callsign.

Version 1.0.1.0 of QW5 Lizard, released on September 21, 2019, is a specialized logging program designed for Windows notebooks, particularly for outdoor operations and contest participation. It supports individual configuration and input masks, making it suitable for various HF and VHF/UHF contests. The software prioritizes data security, with a planned feature for live upload directly to the GMA database, catering to activations of references such as mountains, WCA, lighthouses, and WWFF. This logging tool offers robust export capabilities, including EDI for NAC and IARU Region 1 Contests, as well as standard ADIF and Cabrillo formats. The program has undergone extensive testing and deployments by various stations, demonstrating its utility in real-world contest scenarios, such as the Holzhammer Contest. Future extensions for specific contests are also anticipated, enhancing its versatility for the competitive ham radio operator.

Accessing the official Estonian amateur radio call sign database is facilitated through this resource, which offers a direct search utility for **ERAU** registered licensees. Users can input a call sign to retrieve associated public information, ensuring accurate identification of Estonian stations. The system directly queries the national amateur radio society's records, providing real-time data on active **ES-prefix** operators. This utility is distinct from global callbook services, focusing exclusively on Estonian amateur radio operators. It serves as a primary source for verifying call sign authenticity and operator details within the country's regulatory framework. The interface is streamlined for quick lookups, making it efficient for DXers and contesters targeting Estonian entities. The resource's direct integration with the Estonian Radio Amateurs Union (ERAU) database ensures the presented information is current and authoritative, reflecting the latest licensing status and operator details for the amateur radio community.

AA DX Group was founded in March 1, 1974 in The Netherlands. Our members was more than 10000 from all over the World. Because during the years many of our members became "Silent Keys" or they are not active on the air anymore, we deceide to make new fresh group and to delete all old database. So, we are the new - old Alfa Alfa DX Group and you are welcome to be our member. We make avaiable all Alfa Alfa numbers for new and active CB members and SWL ( Shrot Wave Listeners ). Alfa Alfa World Wide DX Radio group is looking or ACTIVE CB Operators and SWL stations ! The New AADX team in in 2024 Main base in 178AA000 178AADX000 in Belgaria

Swan provides a real-time, browser-based visualization of **meteor radiants** and forward scatter corridors, serving as a modern re-imagining of the classic Virgo meteor sky visualization tool. It displays meteor radiant and radio scatter geometry, offering both visual and numerical skyview data. The tool updates in real-time, showing current sky conditions and allowing users to pause and review specific timeframes for analysis of meteor shower activity and potential radio propagation paths. This enables operators to identify optimal windows for **meteor scatter** contacts. Operators can utilize Swan to predict and optimize their meteor scatter DX attempts by understanding the geometry between their station, meteor radiants, and potential receive stations. The interface presents critical data points for assessing forward scatter opportunities, which is crucial for maximizing short-duration meteor burst communications. By observing the real-time skyview, users can correlate meteor activity with observed signal enhancements, refining their operating strategies for specific meteor showers or random meteor pings.
