QSO Predictor

Real-time tactical assistant for FT8 and FT4 amateur radio.

QSO Predictor shows you the view from the other end of the QSO — what the DX station is hearing, who’s in their pileup, and which frequencies are clear at their location. Stop calling into pileups you can’t hear, and stop wasting calls on paths that aren’t open.

What it does

  • Target perspective band map — reconstructs what the DX station’s region is decoding, using PSK Reporter data filtered by geographic proximity
  • Frequency recommendations — identifies clear frequencies at the target’s location, not just yours
  • Propagation confirmation — shows whether your signal is reaching the target’s region before you call
  • Local intelligence — learns behavior patterns of stations you observe and predicts their calling style

Works alongside WSJT-X or JTDX via UDP integration. Advisory only — you keep full control of your radio.
