HF Propagation & Band Openings

Know when a band opens from where you are. HAMSignal watches live NOAA solar data and tells you when HF conditions improve at your QTH — not just when a storm hits. Set your callsign and grid once, and your phone (or Apple Watch) buzzes when 10m, 15m, or 20m opens. BAND-OPENING ALERTS • A notification when a band opens from your grid square, checked in the background while you're away • Based on live SFI, K-index, and A-index, with a day/night model per band • Especially useful on 10m for Technician licensees, and more valuable as Solar Cycle 25 declines and openings get rarer LIVE CONDITIONS…
