Yup. A long wire just returned wideband noise all the way to 30MHz. No sign of a radio station.

Bought a Wellbrook mag loop - total silence apart from radio stations. A real revelation.

Now Wellbrook are closing down due to the guy retiring. But you can build your own - there are recipes and an amplifier design that is better than Wellbrooks https://www.george-smart.co.uk/projects/wellgood-loop/ .

If mine packs up, I'll definitely build one of those.
