History of radio

Hello, this site is dedicated to all radio enthusiasts in Queensland Australia, It deals with information learnt over the years that I have been associated with radio.

Few inventions have shrunk the world like the wireless. The ability to communicate through clear air over vast distances has wrapped the globe in clouds of talk. Just over a hundred years ago, the first faint buzzing messages were beamed, not across the oceans but from the attic to the garden of a house in Bologna. 1996 is the centenary of the inventions of the wireless by Guglielmo Marconi. December 12th saw the world's first public demonstration, at the Toynbee Hall.The invention of radio during the second half of the 19th century marked a turning point in the way people communicated with one another, from the early begins when CLARKE MAXWELL demonstrated mathematically how electromagnetic "actions" did spread with an "undulatory" movement, and then in 1887 the German HEINRICH HERTZ, using periodic currents at very high frequency, demonstrated the real existence of electromagnetic waves transforming the "undulatory movement" into a stationary phenomenon, which could be easily checked in a laboratory. For the full story just click onto the transceiver at the top left of the screen.

There is also listed on this site a full range of frequency's for both 27mg and UHF CB and a very comprehensive page on the UHF repeater sites situated through out Queensland, there Identification call signs and locations. Click on ether of the mobile transceivers to the left.

I have also included a small page detailing the theory of antennas and a cutting and spacing list to make one or two of them. Antenna switch.

Do you want to learn about electronics, well here is you chance, on this site a very comprehensive look at basic radio electronics, when complicated it will give you a greater understanding of how radio works, and most certainly help if you are thinking of sitting for you amateur exam.

I hope you enjoy this page, and if you can make any suggestions on how to improve it’s content, please do not hesitate to E-mail me.
