Battery valve set current consumption.

The label says "Sea Wave", then DF Unit below that. Just wondering if it was possibly part of a larger installation. Looking at the metal cabinet work, it seems to be hand built, with a good coat of Hammerite paint job. However, the antenna unit looks factory built. Have you removed it Trevor ? There might be a manufacturer's name stamped on the underside somewhere, which could help trace who supplied the kit. I vaguely recall that Heathkit, or a similar DIY company, used to supply RDF radio kits years ago.
