U2.DigiFlow

U2.DigiFlow (Digital QSO Automation)

U2.DigiFlow is a modern, high-performance automation system designed to optimize and execute contacts (QSOs) for digital modes, specifically FT8 and FT4.

How it Works

DigiFlow runs in tandem with the popular WSJT-X software, interfacing directly through network UDP APIs. It analyzes the incoming waterfall signals, decodes messages, and makes intelligent decisions regarding which callers to reply to or call based on active priorities and award status.

Key Features

• Smart Sequencing: Automated state machine that runs digital QSO protocols smoothly, managing standard signal exchanges from report to 73.
• Callsign Priority Sorting: Automatically flags and prioritizes needed DXCC entities, new grids, or stations providing rare award points.
• Collision Avoidance: Checks transmitter timing slots to minimize overlaps and maximize signal success rates.
• Direct U2.Log Syncing: Once a contact is confirmed, DigiFlow instantly records the QSO details to the unified U2.Log database.
