M7NXS is a UK amateur radio station operating from North Yorkshire, England, in Maidenhead grid square IO94. Licensed in 2026, with a much longer background in IT that predated the callsign by some decades.
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 receivers behind OWRX.UK — a free online WebSDR anyone can use with no account — are all fed from this station's antennas: three HF receivers (a Web-888 and two SDRplay RSP1Bs) sharing the long wire, one RTL-SDR on the discone, and a dedicated ADS-B receiver. Anything you hear on them, M7NXS is hearing too.
AI ham radio, with a human in charge of the licence. Since late September the station has been run in part by Claude, an AI from Anthropic. Claude steers the AI Hopper (the discone’s RTL-SDR) and, since 1 October, the two RSP1B receivers, choosing which FT8 bands each one listens to so that the station decodes as many signals as possible, and the furthest ones. Every FT8 decode is counted and scored, and the receivers learn from the results. The IC-7300 is only ever lent to the AI to listen and learn. Nothing here is ever transmitted by the AI. M7NXS takes his Ofcom licence seriously: he is responsible for making sure it never happens, and the AI is only given receive-only access, with guardrails that stop it keying a transmitter. How the AI is used.
FT8 on 14.074 and 7.074, and JS8Call on 7.078
— both daily drivers rather than occasional experiments. WSPR and FT4 alongside,
with Winlink and LinBPQ packet for message handling.
The main FT8 bands are covered by two or more independent receivers most of the time. The Web-888 watches all eleven bands on its own, 160m to 6m; the two RSP1Bs (HF 2 and HF 3, both handed to Claude on 1 Oct) are steered by an AI that moves each onto the band windows that are open and worth covering, 160m to 6m, never both on the same window, to catch the furthest and rarest stations. The discone receiver, the AI Hopper, sits on the FT8 band it will add the most to when nobody is using it, catching what the others missed — its brain is Claude Opus 5.5 (watch it choose, live), and goes to 10m, 12m or 6m when they open (so far it has caught nothing on 6m, which we are investigating). The AI Hopper now also hops to 160m and 60m (1 Oct), so even 160m has a second receiver. The overlap is deliberate — it produces a continuous measurement of wideband receiver performance against dedicated narrow-window SDRs sharing the same antenna. See the coverage matrix, the live decode feed, or why it is built that way.

The fastest way to reach M7NXS is a QSO — FT8 or JS8Call on the frequencies above, or the club net on a Sunday evening.
There is no email address, on purpose. M7NXS would rather not be easy to reach unless you have a radio. At the time of writing his inbox holds 24,537 unread messages, with no plans to read or clear any of them, and email is antiquated and insecure anyway. Find him on the air instead.

Public receivers: OWRX.UK · Live decodes: feed.owrx.uk · Questions: FAQ
Every 10 minutes a plain script (no AI) checks the station server (it gathers every receiver’s decodes and runs the hopper), the AI Hopper’s own receiver and the web server that serves these pages: how busy the processor is, how much memory and disk space is left. A warning here, and in a banner at the top of the hopper page, means something should be looked at soon. If a problem is still there 10 minutes later, a short Claude run looks into it and fixes it if it safely can (at most twice a day). Every week Claude reviews how the checks behaved and improves them.
