Positions are computed live from public TLEs (CelesTrak) via SGP4. Click a satellite for orbit data, look-angles from the ⌖ crosshair, next pass, and how to receive it. Aim: click a spot → ⌖ Recenter → the pane reads look-angles from there.
Starlink is off by default (large + fast). TLEs cached ~6 h; predictable orbits stay accurate for days offline.
Mic decodes CW heard through your microphone. Capture audio decodes a stream playing on your machine — share a tab/window and tick “Share tab/system audio”, so you can point it at a Broadcast station, a Hoseline feed, or any CW you're listening to. Auto-adapts to speed; adjust gate if it misses or runs together.
