This online tool is a specialized web-based utility for orchestrating multi-operator HF contest and DXpedition activities. This tool, _Rig2Cast_, assists station managers in meticulously planning operator shifts, ensuring adequate rest periods, and crucially, preventing operational conflicts such as assigning a single operator to multiple radios concurrently. It integrates support for SO2R operations and offers real-time simulation of operator requirements, a feature I've found invaluable in pre-event planning. The scheduling engine incorporates five distinct algorithms: greedy fairness balancing, round robin, maximum coverage, simulated annealing, and a fatigue-aware model. These algorithms enforce critical constraints like minimum/maximum shift durations and mandatory rest times across all radios, which directly impacts operator performance over long events. My field experience confirms that such robust constraint management is essential for maintaining peak efficiency during intense operations. Key features include distributed multi-station support, printable per-operator cards, flexible band activity windows, and real-time editable operator slots. The drag-and-drop shift management, coupled with full cross-radio swap support and smart constraint feedback (valid targets in green, invalid in red), streamlines complex scheduling tasks. The system's design ensures user data privacy, as no information is stored on the server; schedules are saved and reloaded locally.
