HamBand vs LY4A DX Reminder

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. Pull to Refresh Always fetching fresh data directly from NOAA. No subscriptions, no accounts, no ads. HamBand is built by KD3CLW, a licensed amateur radio operator in western Pennsylvania. 73 de KD3CLW

Tell it which callsign you are waiting for, on which bands and in which mode. From then on ly4a.com watches five DX clusters for you every minute and sends an alert to your phone the moment that callsign shows up — on the lock screen, with the frequency, band, mode, spotter and source. • Five sources at once — DXScape, DXSummit, DXHeat, PSK Reporter and Reverse Beacon • Band and mode kept apart — 20m CW and 40m SSB never mix, and CW means real CW only • 160m to 70cm — all HF bands including 60m, plus 6m, 2m and 70cm • Five modes — CW, SSB, FT8, FT4 and RTTY • Checked every minute — by ly4a.com, so the app does not need to stay open and does not drain the battery • Alert repeat you choose — on every new spot, or at most every 1, 5, 10, 30 or 60 minutes for the same callsign, band and mode • Spots list — every match, with time, frequency, spotter and source • iPhone and iPad • 15 languages — English, Lithuanian, German, French, Russian, Spanish, Polish, Italian, Ukrainian, Czech, Portuguese, Japanese, Latvian, Estonian and Hungarian Free, no ads, no account. The app keeps only what it needs to work: an anonymous device identifier, your notification token, the callsigns you watch and your alarm settings. Nothing identifies you, and deleting the app removes it all. Sources: DXScape, DXSummit, DXHeat, PSK Reporter, Reverse Beacon.
