The stamp on this
cover and the cover itself were issued to commemorate the 50th Anniversary of Regular Radio Broadcasting in Australia.
Radio is a way of
transmitting signals without wires. It uses electromagnetic radiation to transmit
sounds made in one place to listeners in many places. Radio is also known as
'wireless telegraphy', or 'wireless', as earlier methods for sending signals
(such as the telegraph and telephone) used wires. Australia adopted radio for
communications at sea and in lighthouses, and wireless telegraphy gradually
replaced the Overland telegraph which
had been completed in 1872.
From the first public
radio broadcast in 1923, public and domestic radio sets encouraged communities
of listeners. Families and groups gathered around a wireless box or radiogram.
Then as radios became cheaper and more portable – particularly with the
introduction of transistor radios from the 1950s – personal radios became
common, and individuals could listen according to their own preferences.
In December 1922, the Australian Government issued “The Regulations: radio
laws for the amateur”. The first licensed broadcast station in Australia, under these new
regulations, was 2CM, owned by Charles
MacLurcan. The licence (number one) was signed by the Prime Minister, The
Rt Hon Billy Hughes. Callsign 2CM is listed by the Federal Government as “Never
to be Reissued”, in recognition of the pioneering achievements of Charles
MacLurcan. 2CM was the first radio station in Australia to publish a regular
program guide.
Thank you Maria.
