Built for radio amateurs: one full-screen world view in 3D globe or flat map, with grey line, NOAA solar indices and HF band conditions, a worldwide F5LEN tropo overlay for VHF openings, aurora and MUF layers, your QTH, optional cities and grid/CQ/ITU layers, plus live spots, logging context, N1MM+, satellite footprints, and a Special Event mode for club stations. Fewer tabs, more time on the air.

Shack-ready situational awareness, wired into the services hams actually use, not a generic weather app. New: a full worldwide tropo map layer from F5LEN.
See where tropospheric enhancement is building across the globe: the current 3-hour refractive-index forecast from F5LEN, colour-matched to tropo.f5len.org, on both the flat map and the 3D globe. Toggle with T when you are watching VHF openings.
Switch between a 3D globe and a 2D flat map to match your operating style, from global long-path awareness to familiar desk-map viewing for daily station use.
Layer grey line with twilight, NOAA solar flux, A/K indices, sunspot number, HF band conditions (day/night), optional VHF aurora and E-skip (Europe or North America), aurora and MUF overlays (keyboard toggles), plus optional grid / CQ / ITU and city clocks. Pair with the tropo overlay when VHF ducts are the story of the day.
Telnet DX Cluster (DX Spider / AR / CC) with spots on the map, labels, and optional propagation lines. PSK Reporter: who hears you and who you hear, map markers, and a scrollable widget with an SNR bar per spot. Reverse Beacon skimmer spots for your callsign, map markers, and SNR context at a glance.
Live Summits on the Air and Parks on the Air spots on the map and in widgets, plus planned SOTA alerts and scheduled POTA activations. Double-click a marker or row to open the summit or park page.
Add callsigns you care about and get alerted when they appear on DX Cluster, PSK Reporter, Reverse Beacon, SOTA, or POTA, so you do not miss a chase while operating.
Optional Az/El widget for Sun and Moon from your station coordinates or grid, useful for satellite windows, Earth-Moon-Earth, and antenna planning.
N1MM Logger+ UDP (radio, app info, recent QSOs on the map), Cloudlog API for stats and contacts, plus QRZ Logbook and standard ADIF file support so recent QSOs can be mapped directly on your station display.
Follow upcoming and live contests in a dedicated widget with clear status, start/end timing, and countdowns in days, hours, and minutes, with cleaner spacing for quick at-a-glance reading.
Track selected amateur satellites with optional labels and visibility footprints on the map (TLE-based), plus an Upcoming Passes widget showing AOS/LOS, max elevation, track direction, and live ETA countdowns.
Special Event mode for field days and club open days: branding, last-worked banner, contacts today, distance, fed by Cloudlog or N1MM+.

DXChrono is a full desktop map app, not a lightweight HamClock clone. A normal PC or mini-PC is comfortable; a Raspberry Pi 4 or 5 works as a dedicated wall display.
64-bit PC or Mac. 4 GB RAM is the minimum; 8 GB is more comfortable. A typical Intel or AMD mini-PC is a good shack display. 1080p is the sweet spot; 4K is fine on a decent machine.
Pi 4 or Pi 5 with a 64-bit OS. 2 GB RAM is the floor for a 2D wall display; 4 GB is recommended. Use the ARM64 Raspberry Pi download.
Raspberry Pi 3 and earlier, 32-bit ARM, and small HamClock appliances such as the Inovato Quadra (Pi 3-class CPU). Keep HamClock on those; run DXChrono on a mini-PC or a Pi 4/5.
Full detail, including how to tune a 2 GB Pi: System requirements in the docs (opens in new tab).
Buy DXChrono Desktop once and run a powerful, cross-platform station display built for daily operation — including the new worldwide F5LEN tropo overlay for VHF.
