The Open Signal network, right now
Who is on the air, the pictures the network has shared, and how well signals are getting through — read live from the Open Signal service each time this page loads.
Where the network is
On the air
Every operator →Nobody is beaconing at the moment — stations appear here while they have Open Signal running, and drop off 30 minutes after their last beacon. The band is quiet, not broken.
How signals are getting through
When a station decodes someone’s picture, it files a reception report — who copied it, at what signal-to-noise ratio, on what band.
Every reception report on record, plotted by how far it travelled and how cleanly it arrived. As the network spreads out and more of it moves to HF, the clusters should pull apart by band.
Every station against every other, coloured by how strongly the signal arrives. Direction matters: hearing a station is not the same as being heard by them, and the two halves of a path are often quite different.
Rows transmit, columns receive; the number in each cell is how many reports that path has produced. Hover a cell for the detail — and for the same path in the other direction, which is often not the same at all.
When the network is on the air
If you want to catch someone, this is when to be listening. Both charts count the pictures themselves, and both show their quiet slots rather than hiding them — an empty hour is an answer too.
The network in numbers
Counted from the pictures and reception reports themselves, so these match what you can see above. Nothing here counts web traffic — only what happened on the air.
Whose station sent the file to the service — often a station that copied the picture off the air rather than the one that transmitted it.
Archive holds 1,773 pictures, going back to 23 July 2026.
What these numbers do and don’t know
Positions come from each station’s Maidenhead locator — the same square they already transmit on the air, and no finer. Only operators who opted in to publishing appear in the pictures. History starts when the service began recording, and the distance and signal records only know about contacts reported through the service: purely RF contacts that never touch the internet are invisible here, so treat these as a floor, not a full picture of activity.
Band, mode and frequency figures are counted from the most recent pictures rather than all history, so they describe what the network is doing lately.
