HamBand - HF Band Conditions HamBand gives amateur radio operators instant, real-time HF band condition assessments based on live solar weather data from NOAA's Space Weather Prediction Center. Whether you're heading out for a Parks on the Air (POTA) activation, setting up for Field Day, or just checking conditions from the shack, HamBand tells you what the bands are doing right now - no account, no setup, no clutter. Band Conditions Get instant Good, Fair, or Poor ratings for the five primary HF bands - 10m, 15m, 20m, 40m, and 80m - based on real solar physics. Ratings are calculated from the Solar Flux Index (SFI) and K-Index using band-specific propagation thresholds. Greyline Visualizer Watch the day/night terminator move across a live world map in real time. When your QTH sits on the greyline, low-band DX on 160m, 80m, and 40m lights up — so instead of guessing when that sweet spot rolls through, you can see it coming. 7-Day Trend Charts Track how solar conditions have evolved over the past week with interactive K-Index and SFI trend charts. Spot incoming geomagnetic storms before they kill your signal. Live Solar Data See the current Solar Flux Index, K-Index, and last updated time at a glance. Tap either metric for a plain-English explanation of what it means for your operating. Apple Watch Companion Check band conditions right from your wrist. The Apple Watch app and complication keep key solar indices and band ratings accessible without touching your phone - perfect when both hands are on the antenna.
