M7NXS is a UK amateur radio station operating from North Yorkshire, England, in Maidenhead grid square IO93lx. Licensed in 2026, with a much longer background in SDR and RF that predated the callsign by some years.
The station is built around one idea: it should be automated, always on, and useful to other people without anyone having to ask. That is why the receivers are public, and the decode feed is public. There is very little ragchewing here and a great deal of data.
The five receivers behind OWRX.UK are all fed from this station's antennas. Anything you hear on them, M7NXS is hearing too.
FT8 on 14.074 and 7.074, and JS8Call on
7.078 — both daily drivers rather than occasional experiments. WSPR
and FT4 alongside.
Every FT8 band from 10m to 160m is covered by two independent receivers at once, with the Web-888 on all ten. The overlap is deliberate — it produces a continuous measurement of wideband receiver performance against dedicated narrow-window SDRs sharing the same antenna. The coverage matrix shows which receiver covers which band, and the live decode feed shows the result.
