Radiogram (device)

Radiogram (device) is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Radiogram (device) rather than just read about it. In short: In British English, a radiogram is a piece of furniture that combined a radio and record player. The word radiogram is a portmanteau of radio and gramophone.

Key takeaways

  • Radiogram (device) belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Radiogram (device) to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Radiogram (device) from memory before moving on to harder problems.

Reference excerpt

In British English, a radiogram is a piece of furniture that combined a radio and record player. The word radiogram is a portmanteau of radio and gramophone. The corresponding term in American English is console.

Popularity Radiograms reached their peak of popularity in the post-war era, supported by a rapidly growing interest in records. Originally they were made of polished wood to blend with the furniture of the 1930s, with many styled by the leading designers of the day. An expensive instrument of entertainment for the house, fitted with a larger loudspeaker than the domestic radio, the radiogram soon began to develop features such as the record autochanger, which would accept six or seven records and play them one after another. Certain recordings could be ordered as a box set which would combine the recorded piece in order, to suit an autochanger set-up. In the 1940s and 1950s, sales of the radiogram, coupled with the then-new F.M. waveband, and the advent of the 45 rpm single and the LP record, meant that many manufacturers considered the radiogram to be more important than the fledgling television set sales. Later models took on the modern lines, piano gloss finish and plastic and gilt trim of the 1960s. Stereogram versions became available to take advantage of stereo records. As tape formats grew in popularity, some later models also incorporated reel-to-reel tape decks, cassette decks, or 8-track tape players, or the ability to connect external tape decks.

Replacement As valve radio development ended in the late 1960s and transistors began to take over, radiograms started to become obsolete. By the late 1970s, they had been replaced by more compact equipment, such as the hi-fi and the music centre.

Rarity Since radiograms were manufactured in such huge numbers they are not as rare or valuable as TV sets or table radios from the same period. An exception to this are models from certain manufacturers which have become collectable such as Hacker Radio Ltd., Dynatron, Blaupunkt, Braun, and SABA.

Worked examples

Example 1 — a first encounter with Radiogram (device)

Start with the simplest possible case. Write down what Radiogram (device) claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Radiogram (device) before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Radiogram (device) ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Radiogram (device)

In research
Radiogram (device) appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Radiogram (device) in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Radiogram (device) is common in secondary-school and first-year university syllabi. It links to neighbouring topics Audio players, Consumer electronics, Decorative arts, so understanding it makes those chapters shorter.
In everyday life
Look for Radiogram (device) outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
