The Listener In

A weekly publication, sold across Australia, which first appeared on
January 10, 1925.

It contained details of daily mediumwave radio programs from Australian stations for the following week

The magazine had many features, including constructional articles for receivers, crystal sets, antennas, amplifiers, adverts for Melbourne company’s selling radio and electrical equipment, ads for  medicines, books for home mechanics and a page for Little Listeners conducted  by “Wiry” the wireless Cat.

A shortwave section was introduced in the early 1940s.

The "Listener-In" ceased publication in 1955.
