Radio News (02:10) April 1921

Hugo Gernsback, editor

"The radio engineers of the Telefunken Co. have designed a special panel, on which are fixed all the instruments composing a set. The wiring is apparent and the set may be operated as a regular set. The teacher can show the various elements of the set in working order and show what happens when a change is made in the circuit or the set is tuned. This clever idea greatly helps the students to understand the practical operation of a set and at the same time shows the diagram of connections in a clearer manner than any drawing made on a blackboard."
This April 1921 issue of Radio News features the cover story “A New Radio Instructor” that describes a radio “simulator” used to teach the principles of radio. Other articles include part 3 of Who’s Who in Radio featuring Sir Oliver Lodge, the first annual amateur radio show and convention, new British apparatus, and a new German recording device.
