OWRX.UK

Your radio listens to one band at a time. This listens to all of them.

The chart above is every FT8 signal these antennas have heard in the last fifteen minutes, broken down by band. The decode feed is the last minute, refreshed every cycle as the decodes land. Fifteen minutes is long enough to show a trend and short enough to still be true when you look at it.

The point is the question you can't answer from inside WSJT-X: is twenty metres dead, or is the whole band plan dead? If 20m has gone flat but 30m is lit up, that's visible here in a glance — and it's a decision to retune rather than a decision to go and make a cup of tea. Ten bands, two receivers each, all day and all night.

These are real signals on real wire — a 41.7 m end-fed long wire and a discone in a North Yorkshire garden, not an aggregation of other people's spots.

On the decode feed you can upload your own .ADI file, and every line on the page immediately recolours against your log instead of M7NXS's: magenta for an entity you've never confirmed, pink for one you have but not yet on that band.

It sticks to your browser session, so you can park the feed on a second monitor and leave it running. Your file is yours; nobody else's page changes.

No account. No login. No email address. Upload a log or don't — the feed works either way. That's the whole arrangement.

Each FT8 band is deliberately covered by two independent receivers, with the Web-888 on every band. The overlap is the point: it turns the decode feed into a continuous, self-comparing measurement of how a single wideband receiver performs against dedicated narrow-window SDRs on the same antenna.

The feed is first decoded, first displayed, with one exception — the Web-888 takes precedence. If another receiver decodes a signal first and the Web-888 then decodes the same signal, credit is reassigned to the Web-888.

That is intentional. It means any line not tagged Web-888 is a decode the Web-888 missed, so the feed reads directly as a list of the wideband receiver's gaps rather than as a race between receivers.

The IC-7300 MK2 transceiver can also be tuned to any band and its decodes appear in the live feed. It is deliberately excluded from the band chart, though: it parks on one band for hours at a time, and including it would tell you where the rig is pointed rather than where the traffic is.

Counts in the chart are de-duplicated per callsign, per band, per 15-second cycle, so one station calling repeatedly counts once per cycle rather than inflating its band. The number on the DECODES / 15 MIN tile is the sum of the bars above it — same tally, shown two ways.

Full station details, antennas and the rest of the digital-mode stack are on the M7NXS station page.

OWRX.UK provides public access to a collection of software-defined radio receivers operated by M7NXS from North Yorkshire, UK — covering HF, VHF and UHF, including amateur radio, digital modes, utility transmissions, satellite activity and general spectrum observation.

Every receiver feeds the shared live decode feed, de-duplicated into a single rolling view with the receiving station tagged on each line.

Select a receiver above to access its live SDR interface. All receivers are remotely accessible over the internet, with no login and no registration.
