HAMSignal vs HamBand

Get an alert when your HF band is likely open at your QTH. HAMSignal rates each band, day and night, from live NOAA solar data. Made for licensed amateur radio operators. ALERTS • Band alerts (80m to 10m) follow the solar forecast by default: SFI and K-index, day and night, with thresholds you can adjust. • Or choose measured: it counts stations that receivers near you decode on PSK Reporter, so it needs active receivers in your area. • Four free space-weather alerts (M-class flares and up, G1 storms and up, strong aurora, proton events), plus custom alerts on SFI, K, solar wind, X-ray and more • Background checks run when iOS allows, so an alert can arrive late. Settings > Alert timing shows how late. CONDITIONS • Every HF band rated open, fair or closed at your location, from NOAA SWPC data • What can I work right now (US): open bands legal for your license class, with FCC Part 97 limits • Am I being heard: who decoded your signal in the last hour, from PSK Reporter • A VHF card for 6m, 2m, aurora and the sporadic E season • 27-day forecast, history, grey line map, solar imagery and a path predictor OPERATE • DX cluster and POTA spots, and PSK Reporter activity for your grid • POTA self-spotting that queues offline, POTA and SOTA lookup, Activator Mode, satellite passes, APRS and your repeaters • Offline logbook with unlimited QSOs, iCloud sync, ADIF import and CSV export, plus pocket tools from antenna length to Morse HAMSIGNAL PRO $9.99 per year with a 14-day free trial for new subscribers, or buy Lifetime once. You get a reminder on day 12. • Alerts for every band, unlimited custom alerts, and measured openings to the continents or DXCC entities you pick (free: one band alert, one custom alert) • 6m, 2m and aurora-on-VHF alerts, tagged sporadic E, aurora, TEP or meteor scatter • Heads-up alerts for storms (forecast, or likely within hours), HF radio blackouts and a good 10m day tomorrow • DX spot alerts, and POTA hunter alerts with spots you logged today crossed out • Heard map with up to 30 days of history, and an alert when a new continent or DXCC entity hears you • Greyline sked alerts, a morning briefing, and alert controls such as quiet hours • Path planner: likely openings over the next 48 hours, with an alert 30 minutes before (a model estimate) • Saved locations, and Rover mode, which can switch when you arrive at one • LoTW confirmations, and DXCC, WAS and VUCC lists (free shows your counts) • Contest Mode, and ADIF, Cabrillo and Field Day export • Live Activities for an operating session and a greyline countdown • A full-screen shack display for a phone on a stand or an iPad • Home Screen, Lock Screen and StandBy widgets, and the Apple Watch app With the app closed, live-data alerts rely on background refreshes, so they are likely, not guaranteed, and show their data's age.

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.
