Marconiphone

Marconiphone 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 Marconiphone rather than just read about it. In short: Marconiphone was an English manufacturer of domestic receiving equipment, notably radio receivers and reel-to-reel tape machines. Early history After World War I, the Marconi Company began producing non-industrial receivers, principally for the amateur market, at the Soho premises of The Marconi Scientific Instrument Company.

Key takeaways

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

Reference excerpt

Marconiphone was an English manufacturer of domestic receiving equipment, notably radio receivers and reel-to-reel tape machines.

Early history

After World War I, the Marconi Company began producing non-industrial receivers, principally for the amateur market, at the Soho premises of The Marconi Scientific Instrument Company. In 1922, the Marconi Company formed the "Marconiphone" department, to design, manufacture and sell domestic receiving equipment. This equipment complied with Post Office specifications and tests, and was therefore awarded the BBC authorisation stamp; initially sets were made at the Chelmsford Works. In December 1923, the 'Marconiphone' department was formed as a subsidiary of the Marconi Company. Some Marconiphone Company sets were made at the Sterling Telephone Company (STC) Works at Dagenham. However, design and research of these domestic receivers still continued at Chelmsford.

Gramophone Company In December 1929, the Marconiphone was sold to the Gramophone Company, along with the right to use the trademark "Marconiphone" and the copyright signature "G. Marconi" on domestic receivers. The Marconi Company never re-entered the domestic radio market. In 1931 the Gramophone Company became Electric and Musical Industries (EMI) and produced domestic and radio receivers using the Marconiphone trademark. In 1936, the Marconiphone company moved into the production of cathode ray tubes and television receivers and in 1953 they were still manufacturing television sets. From 1957, Marconiphone receivers were made under licence by the British Radio Corporation, a subsidiary of Thorn Electrical Industries, and the products of the two companies became extremely similar.

Mobile telephones The Marconiphone brand was revived in the late 1980s and used by a division of GEC-Marconi for mobile phones. Phones made by companies such as NEC were given and additional small rectangular metal plate with the Marconiphone logo. Marconi acted as a service provider for Cellnet and Vodafone in the UK before selling the customer base to Mercury in 1991.

Worked examples

Example 1 — a first encounter with Marconiphone

Start with the simplest possible case. Write down what Marconiphone 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 Marconiphone 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 Marconiphone 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 Marconiphone

In research: Marconiphone 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 Marconiphone 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: Marconiphone is common in secondary-school and first-year university syllabi. It links to neighbouring topics Defunct manufacturing companies of England, Electronics companies of the United Kingdom, Marconi Company, so understanding it makes those chapters shorter.
In everyday life: Look for Marconiphone 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.

Why does Marconiphone matter?

Because it connects several science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Marconiphone?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
