W.G. Pye & Co.
Ltd. was founded in 1896 in Cambridge by William George Pye, an employee of the
Cavendish Laboratory, as a part time business making scientific instruments. By
the outbreak of World War I in 1914 the company employed 40 people
manufacturing instruments that were used for teaching and research. The war
increased demand for such instruments and the War Office needed experimental
thermionic valves. The manufacture of these components afforded the company the
technical knowledge that it needed to develop the first wireless receiver when
the first UK broadcasts were made by the BBC in 1922. Instruments continued to
be designed and manufactured under W G Pye Ltd, later situated in York Street
Cambridge, while a separate company was started to build wireless components in
a factory at Church Path, Chesterton.
In 1924, Harold Pye, the son of the founder,
and Edward Appleton, his former tutor at St. John's College, designed a new
series of receivers which proved even more saleable. In 1928 William Pye sold
the company, now renamed Pye Radio Ltd., to C. O. Stanley, who established a
chain of small component-manufacturing factories across East Anglia.
The new EF50 valve
from Philips enabled Pye to build this high-gain receiver, which was a Tuned
Radio Frequency (TRF) type and not a superhet type.
With the outbreak of World
War 2, the Pye receiver using EF50 valves became a key component of many radar receivers,
forming the 45 MHz Intermediate Amplifier (IF) section of the equipment. Pye
went on to design and manufacture radio equipment for the British Army,
In February 1944, Pye
formed a specialist division called Pye Telecommunications Ltd which it intended
would design and produce radio communications equipment when the war ended.
This company developed, prospered and grew to become the leading UK producer of
mobile radio equipment for commercial, business, industrial, police and
government purposes.
In 1955, the company
diversified into music production with Pye Records. The Independent Television
Authority (ITA) started public transmissions in the same year so Pye had to
produce new television designs that could receive ITV and the availability of a
second channel introduced the need for tuners. Pye's VT4 tunable television was
launched in March 1954
Pye TVT Ltd was
formed to produce broadcast television equipment, including cameras, which were
very popular with British broadcasters including the BBC as well as
international sales. Later in the
seventies when it faced compition from Japanese companies, the company stopped
production. The Pye group of companies was bought outright by Philips in 1976.

Sukhdev immediately
went to the market and purchased a small RCA radio, which had a volume so loud
that it rocked the entire building! It was the very antithesis of the first radio.
Shri Nathji laughed as he listened to its blast. However here was a gift that
would remind him of Sukhdev every time he looked at it or listened to it in the
silence of the Himalayas at Mussoorie.
RCA Corporation,
founded as the Radio Corporation of America, was an American electronics
company in existence from 1919 to 1986. It was founded after world war one,
when the control of the Radio was given back into private hands from the military. In 1929, RCA purchased the Victor Talking
Machine Company, then the world's largest manufacturer of phonographs. The
company made many models of Radios and
phonographs.
RCA was involved in
radar and radio development in support of the war effort. This greatly assisted
RCA in its television research. RCA become a popular manufacturer of televisions
During WWII and beyond, RCA set up several new divisions, for defense, space
exploration and other activities. Later the company also diversified into computers.
RCA antique radios
and RCA Merrill/CT-100s and other early color television receivers are among
the more sought-after collectible radios and televisions, thanks to their
popularity during the golden age of radio, their manufacturing quality, their
engineering innovations, their styling and their name, RCA.
