The ocean wireless boys of the iceberg patrol

A group of young wireless operators undertake sea assignments aboard freighters and liners, deploying portable radio equipment and kite-borne aerials to assist iceberg patrols. Routine message traffic escalates into danger when drifting ice, collisions, and deliberate sabotage produce shipwrecks and leave them marooned on ice floes and remote islands. The episodes interweave technical ingenuity, including portable sets, hand generators, and signaling, with physical adventure: daring rescues, escapes, confrontations with hostile figures, and a hunt for concealed treasure. The narrative follows their inventive problem-solving, teamwork, and perilous voyages through storms, fog, and wreckage until the immediate threats are resolved.
