LY4A DX Reminder
Monitor DX clusters for specific call signs across multiple platforms and modes.
Description
The LY4A DX Reminder application monitors five distinct DX cluster sources—DXScape, DXSummit, DXHeat, PSK Reporter, and Reverse Beacon—to alert amateur radio operators when a specific call sign appears. It supports a wide range of bands from 160 meters to 70 centimeters, including 60m, 6m, 2m, and 70cm, accommodating CW, SSB, FT8, FT4, and RTTY modes. The software operates in the background, checking clusters at user-defined intervals of 1, 5, 10, or 30 minutes, and persists across device restarts.
Alarm functionality is robust, activating even if the mobile device is silenced, by utilizing the alarm channel and illuminating the locked screen. On desktop platforms, notifications remain active in the system tray. Users can directly manage alarms—stopping, snoozing, or deleting them—from the notification interface, enhancing operational flexibility during DX pursuits.
Available in 15 languages, including English, Italian, German, and Spanish, the application is provided free of charge and without advertisements. It offers optional donation support for continued development. Installation instructions are detailed for Android, Windows 10/11 (64-bit), and macOS 12+, addressing common system security prompts for unsigned applications.
