HAMSignal

The solar weather app for HAM radio operators. Real-time band conditions, push alerts, and propagation tools in one place. **The problem we solve:** You know conditions are good. You're waiting for the bands to open. But most apps only tell you when there's a storm - not when the conditions improve. HAMSignal watches K-index and SFI, and tells you when a band opens from your QTH. --- **Real-Time Solar Data** K-index, SFI, A-index updated every 15 minutes from NOAA. All 8 HF bands rated open/
