HAMSignal vs Greyline FT8

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.

Greyline FT8 is a highly portable, capable amateur radio app designed specifically for field operation with an iOS device. I designed this app because I got very used to my full-stack FT8 solution: GridTracker, WSJT-X, PSK Reporter, WRL Desktop, several browser tabs, and more. But I didn't want the bulk and weight of a full Windows PC in the field. At the same time, while there are excellent and lightweight FT8 iOS solutions out there, they were lacking features I really wanted. Greyline is everything you need and nothing you don't. It automatically locates your grid square, performs callsign and calling station DXCC lookups (internet access required), and can even show you real-time spot data from PSK Reporter. Want to adjust your directional antenna? Now you've got the info you need to do it! Greyline also incorporates automated calling features. Gatherer mode calls CQ, responds to the first reply it gets, finishes the QSO and returns to calling CQ all without your input. On the other side of things, Hunter mode listens for CQ calls and pounces on them, finishing a QSO then returning to the live band to find the next. Or, take control of the conversation yourself with standard mode. That's the experience you're already used to from WSJT-X and other digital mode apps. Some other noteworthy features are: - Intelligent automatic free frequency selection - Dynamically adjusted audio delay for virtually drift-free message timing - PSK Reporter integrated Live Spots - Direct-to-QRZ, WRL and private Cloudlog logging and ADI export - Configurable waterfall settings - CQ addendums - CQ filtering for contesting and general courteous operation - Configurable retransmissions - Intelligent log recovery (didn't get that last 73 but want to log the contact anyway? Now you can!) - Log import and export - Antenna tuning - POTA Autospotting - One touch POTA activation and POTA.app-compatible ADIF export - Multiple POTA activation support - And so much more! Greyline uses audio VOX and not serial PTT. Most radios support this with simple cabling or an audio interface like a Digirig.
