Your HamClock, back on the screen in 30 seconds.
Free, runs in any web browser, nothing to install. Works on the same Raspberry Pi and screen you already have.
In memory of Elwood Downey, WB0OEW (SK)
He created HamClock and gave it to the ham community for free. When the original stopped working in June 2026, we built this so his idea keeps running. 73, Elwood.

Put it on your Raspberry Pi
Keep your old HamClock Pi and screen. This makes it open your clock full-screen at startup:
- Open a terminal on the Pi (Raspberry Pi OS with desktop).
- Paste this one line and press Enter:
curl -sL https://hamclock.me/pi | bash
- Restart the Pi. The clock comes up by itself.
Want to see exactly what it does first? Read the script. It only adds a start-up entry for Chromium; nothing is deleted.
Everything you had, plus a few things you didn’t
Greyline map
Live day and night from real satellite imagery, with the path and beam heading to your DX.
Bands from your grid
Built from real FT8 and FT4 signals heard near you, not just solar numbers.
Spots
DX cluster, PSK Reporter, CW skimmers and POTA. Tap one to make it your DX.
Space weather
Solar flux, sunspots, K and A index, X-ray, Bz, solar wind and aurora.
Contests and satellites
What’s on the air now and coming up, and where the ham satellites are.
Fits your screen
A full TV layout for the wall and a compact one made for the Pi 7″ screen.
Other screens
TV or monitor
Open your link in the browser and press F11 for full screen. Smart TV browsers and Fire TV Silk work too.
Old tablet
Open your link, then use “Add to Home Screen”. Turn auto-lock off so it stays on.
Several screens
Use the same link on every screen, or make a different one for each station.
What happened to HamClock?
HamClock was written by Elwood Downey, WB0OEW. For years he gave it away free, and it became the clock on the wall of a great many shacks: a world map with the greyline, space weather, band conditions and DX spots, often on a Raspberry Pi with a small screen.
Elwood became a Silent Key in January 2026. In June 2026 the original HamClock stopped working, and a lot of those screens went blank.
hamclock.me is our tribute: a free web HamClock that keeps his idea running. It is not the original program and is not affiliated with Elwood or his family. It runs in any browser, so it works on the Raspberry Pi and screen you already have, on a TV, or on an old tablet. Set yours up above or open the clock.
Questions
What happened to HamClock?
HamClock was written by Elwood Downey, WB0OEW, who gave it to the ham radio community for free. Elwood became a Silent Key in January 2026, and the original HamClock stopped working in June 2026. Many shack screens and Raspberry Pis that ran it went blank.
Is there a HamClock replacement?
Yes. hamclock.me is a free web HamClock made in tribute to WB0OEW. It has a live greyline map, band conditions, spots and space weather, and runs in any web browser, so there is nothing to compile or update. Other hams have built alternatives too; this one needs no install.
Is this the original HamClock?
No. It is a free web version made in tribute to WB0OEW’s HamClock, with the same layout ideas. It runs in a browser, so there is nothing to compile or update.
Does hamclock.me work on a Raspberry Pi?
Yes. Keep your old HamClock Pi and screen. Run the one-line setup and the Pi opens your clock full-screen in Chromium when it starts. It needs Raspberry Pi OS with the desktop; a Pi 3 or newer is best. There is a compact layout made for the Pi 7″ 800×480 screen.
How do I run HamClock full screen on a TV?
Open your hamclock.me link in the TV’s browser, or on a computer, Raspberry Pi or Fire TV stick plugged into the TV, and press F11 (or use the browser’s full-screen option). Pick Monitor or TV on this page to get the large wall layout.
Do I need an account?
No. Your callsign, grid and layout are saved in your link. Bookmark it, or put it on as many screens as you like.
Does it cost anything?
No. hamclock.me is free. It is supported by coffee donations and the Ham Radio Dude store.
Can I control my radio from it?
Not yet. Tell us which radio you have and we will see what we can do.
