Lake's sub-expedition into the unknown, as everyone will recall, sent out its own reports from the short-wave transmitters on the planes; these being simultaneously picked up by our apparatus at the southern base and by the Arkham at McMurdo Sound, whence they were relayed to the outside world on wave-lengths up to fifty metres.
Guztiek ongi gogoratuko duten bezala, Lakeren azpi-espedizioak bere komunikatuak bidaltzen zituen aireplanoetako uhin laburreko transmisoreen bidez; komunikatuak aldi berean hartzen zituzten hego-kanpalekuko irratiek eta Arkham itsasontziak McMurdo badian; gero, azken honek, mundu osora zabaltzen zituen berrogei metrorainoko uhin-luzerako emisioetan.
