Features‐Overview
Interactive Leaflet map showing DX paths, satellite tracks, propagation overlays, and station locations. Click anywhere to set the DX target. The map supports dozens of toggleable layers — see Map Layers.
Real-time DX spots from the DX Spider network, HamQTH, or custom telnet servers. Spots appear as arcs on the map from spotter to DX station, color-coded by band. Filter by band, mode, continent, or search for specific callsigns. See DX Cluster Setup.
Real-time digital mode reception reports via MQTT. Shows who's hearing your signal (TX) and who you're hearing (RX) on a live map with great-circle paths. Supports both callsign-based and grid-based subscriptions. See PSKReporter.
Live POTA activator spots with park locations plotted on the map. Shows activator callsign, frequency, mode, park reference, and time since spotted. Click a spot to tune your rig (if connected via Rig Listener).
Live SOTA activator spots enriched with summit data (coordinates, altitude, points) from the SOTA summits database. Spots appear on the map at their summit locations.
Live WWFF activator spots showing flora/fauna reference areas on the map.
Real-time solar data from NOAA SWPC: Solar Flux Index (SFI), K-index, sunspot number (SSN), X-ray flux, proton flux, aurora forecast. Includes historical charts and geomagnetic storm indicators.
NASA SDO solar imagery (AIA 193, 304, 171, 94 wavelengths + HMI intensitygram) and Dial-A-Moon photorealistic lunar image. Auto-refreshes every 15 minutes.
N0NBH band condition data showing HF propagation quality for each band (day/night), plus VHF phenomena. Same data source as GridTracker and hamqsl.com.
Hybrid ITU-R P.533-14 predictions combining ITURHFProp with real-time ionosonde data from the KC2G/GIRO network. Shows per-band reliability, MUF, LUF, and 24-hour forecast for any DE→DX path. Mode and power-aware (FT8 at 5W shows different results than SSB at 100W).
34 curated amateur radio satellites with real-time tracking, pass predictions, and footprint visualization. Includes ISS, SO-50, QO-100, FM repeaters, linear transponders, and weather satellites (GOES, METEOR).
Upcoming and active amateur radio contests from the WA7BNM contest calendar RSS feed. Active contests are highlighted with countdown timers. Includes weekly mini-contests (CWT, SST, NCCC Sprint).
Current and upcoming DXpeditions from the NG3K ADXO calendar. Shows callsign, entity, dates, bands, and modes. Active expeditions are highlighted.
Scrolling news headlines from dxnews.com across the bottom of the map. Adjustable text size with persistent preference. Can be paused by clicking.
Live FT8/FT4/JT65/WSPR decodes from WSJT-X, JTDX, or compatible software. Shows decoded stations on the map with grid squares, SNR, and frequency. Supports local UDP, LAN, and cloud relay. See WSJT-X Integration.
Local weather at DE and DX locations via Open-Meteo (fetched directly by each user's browser — no API key needed). Shows temperature, conditions, wind, humidity, and pressure.
Station info panels showing callsign, grid square, coordinates, beam heading (short and long path), distance, and local time. DX target can be set by clicking the map, entering a grid square, or selecting a DXCC entity.
| Theme | Description |

Save and switch between named configuration profiles. Useful for multiple operators sharing one HamClock, or quickly toggling between setups (contest mode, field day, everyday). Each profile saves all panel states, filters, theme, and layout preferences.
OpenHamClock is fully translated into: English, German, Spanish, French, Italian, Japanese, Korean, Malay, Dutch, Portuguese, Slovenian, Catalan, Georgian, Russian, and Chinese.
