About HAMSignal: Ham Radio Alerts
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.

What’s new
Version 3.9 · Updated October 25, 2026
3.9 brings everything new since 3.7. PRO, NEW WAYS TO GET IT • Pro is now $9.99 a year with a 14-day free trial for new subscribers, or buy Lifetime once. The paywall shows the trial day by day, and you get a reminder on day 12. • Bought Pro or the paid app before? You keep Pro, with everything new below, and there is nothing to do. • Installed HAMSignal before this version? Widgets and the Apple Watch app stay free for you. On new installs they are part of Pro. • Redeem an offer code from the Pro screen or Settings. ALERTS • Your existing alerts keep working as before. Band alerts still use the solar forecast (SFI and K-index) unless you choose measured in a band's options. • New: measured band alerts, a choice in each band's options, count the stations that receivers near you decode on PSK Reporter. They need active receivers in your area. With Pro, pick continents or DXCC entities. • New in Pro: alerts for 6m and 2m openings, aurora on VHF, storm and HF radio blackout heads-ups, POTA activators, and a new continent or DXCC entity hearing you. • DX spot alerts (Pro) now also use DX cluster spots while DX > Spots is connected, and PSK Reporter on any screen and in background refreshes. Each says how old its spot is, and you can edit an existing DX alert. • Alert controls (Pro): quiet hours, end dates, distance filters and alert sounds. • Alerts with the app closed depend on background refreshes, which iOS schedules, so they are likely, not guaranteed. Settings > Alert timing shows how late yours arrive. ALSO NEW IN PRO • Path planner: likely openings over the next 48 hours to the places you pick, and a notification 30 minutes before (a model estimate) • Saved locations and Rover mode • Heard map with up to 30 days of history • LoTW confirmations in Awards • Morning briefing notification and widget • Live Activities for an operating session and a greyline countdown • Shack display, and a Shack widget for StandBy FREE FOR EVERYONE • A VHF card on Conditions for 6m, 2m, aurora and the Es season • POTA activator spots in DX > POTA • Your DXCC, state and grid counts on the Awards screen • Still free: live conditions, forecasts, the grey line and propagation maps, DX cluster spots, APRS, satellites, repeaters, who heard you in the last hour, every tool except award tracking, unlimited logging, one band alert, one custom space-weather alert and the four built-in ones Use HAMSignal on more than one device with iCloud? Update them all to 3.9. An older version can drop the QSL received marks that 3.9 reads from imported logs. If Pro doesn't show, tap Restore Purchases on the Pro screen.
