Pye
Telecom
History
Project
This long-term project is dedicated to
all of the people who worked for
the Pye, Philips and Simoco companies
in radio communications over the years.
This web site
attempts to document and celebrate the product history
and achievements in radio communications
of Pye Telecommunications Ltd. of Cambridge, England, its
forerunners and successors.
Over a 70 year period this company was known as
Pye Radio Works Ltd, Pye Ltd, Pye Telecommunications, Philips Radio
Communications Systems (PRCS), Philips Telecom-PMR and Simoco
International Ltd.
The objectives of the
Pye Telecom History project are to preserve the Pye
Telecom Historic Collection, to accurately document the history of the
Company and the development of the product portfolio of radio
communications equipment, and to work towards the establishment of a
public museum display of Pye equipment in the Cambridge
area.
From
2002
to
2007 the project was privately funded. From 2007
the storage of the Pye
Telecom Historic Collection is being
partially
financially
supported
by the
Pye
Foundation.
The core time period of Pye in radio communications is from 1939 to
2002, although the Pye group of companies dates from 1896, and some
parts of the company are still successfully trading under the names
Sepura and Simoco.
The story of Pye in the field of radio communications began with
the involvement of Pye Ltd in the development of
military radar
in the late 1930s and wireless
equipment for the Army in 1940. It progressed through the
development of the
commercial
Private Mobile Radio (PMR) industry (known as Land Mobile Radio (LMR)
in the United States) using analogue transmission, to the
digital communications of today which use the Tetra system and TCP/IP
protocols etc.
