Will my computer run DXChrono?
DXChrono is a full desktop map app with a large world picture, live spots, and an optional 3D globe. It is built for a normal PC, Mac, Linux box, or a Raspberry Pi 4 or 5 used as a shack wall display. It is not a lightweight HamClock clone, so small HamClock appliances are usually the wrong machine.
Supported platforms
| Platform | Minimum | Comfortable |
|---|---|---|
| Windows (64-bit) | 4 GB RAM, 1080p display | 8 GB RAM |
| macOS (Apple Silicon or Intel) | 4 GB RAM, 1080p display | 8 GB RAM |
| Linux (64-bit Intel/AMD) | 4 GB RAM, desktop session, 1080p display | 8 GB RAM |
| Raspberry Pi 4 or 5 (64-bit OS) | 2 GB RAM, 1080p, 2D map as a dedicated display | 4 GB RAM |
Download the matching build from the DXChrono download page. The Raspberry Pi file is the Linux ARM64 build for Pi 4/5 only.
Raspberry Pi as a wall display
A Raspberry Pi 4 or 5 with 4 GB is the Pi we recommend. A 2 GB Pi 4 is the floor: expect a usable 2D wall display at 1080p, a slower first map load, and less headroom if the desktop OS is also running. Use kiosk or a light desktop if you stay on 2 GB.
On a Pi, keep 3D globe auto-spin off if the display still feels sluggish (O in 3D mode), or lower Settings → Map 3D → 3D Auto Spin Render FPS to 10. You can also lower Settings → Display → Frame Rate and use Settings → Performance if startup is heavy. See Troubleshooting → Slow startup or heavy map load.
Mini-PCs
Any typical 64-bit Intel or AMD mini-PC from the last several years is a better shack box than a small ARM HamClock appliance. Prefer 8 GB of RAM (4 GB is workable). Windows or Linux are both fine. 1080p is the sweet spot; 4K works on a decent mini-PC but is heavier.
Machines that are not a good fit
- Raspberry Pi 3 and earlier – too little CPU (and often too little RAM) for a decent map display.
- 32-bit ARM boards – there is no published 32-bit build.
- Small HamClock ARM appliances such as the Inovato Quadra – these are excellent for HamClock, but they are about Pi 3 class (typically 2 GB RAM). Keep HamClock there and run DXChrono on a mini-PC or a Pi 4/5.
Display and network
- Display – HDMI or a built-in screen; 1080p is recommended. 4K is fine on a normal PC or mini-PC.
- Internet – needed for live solar data, spots, and most integrations. The clock, grey line, and some offline features still work without a connection (see Offline and field day).
