Which Major Discoveries led to the Invention of the Two-Way Radio?

(Asked by ‘Scottish’ Pete from Woolwich)

Hey Pete, how’s everything? Thanks for your question.

…And what a question it is. The modern two-way radio, which is a direct descendent of the WW2-era Walkie-talkie, first became recognizable in the years just before the outbreak of World War 2. Its origins are an interesting story in their own right (but I’ll condense it here).

Three names are usually mentioned with regards to the invention of the walkie-talkie… Continue reading

What is Ham Radio & How Does it Work?

Ham radio (so called because its operators were originally derided as being ‘hammy’ in the 19th century, when the technology first emerged) is a term that applies to any form of amateur radio broadcasting.

 

There are designated radio frequency spectra available solely for public use. Uses range from recreation to communication and the non-commercial exchange of ideas. ‘Hams’ take advantage of these frequencies in order to transmit any number of things Continue reading

Essential Services, Essential Technology, Radios at Oil & Gas Plants

Oil and gas are natural resources, but obtaining them isn’t as simple as planting a seed in a patch of arable land. Today, hundreds of thousands of miles of oil and gas pipeline run all over the world, sometimes covering some of the most inhospitable environments known to man.

 

Pipelines that run above ground offer many advantages to oil & gas companies. They are cheaper to build, easier to repair, far simpler to maintain and a lot safer for the environment. However, that same environment also has no qualms about wreaking havoc on the lines, neither do politically motivated saboteurs or occasional wanton vandals who commonly make their presence felt in such places. A pipeline is a complex and intricate operation, which means that in order for everything to go right, nothing can be allowed to go wrong. Continue reading

Inform, Entertain and Educate, Two-Way Radios in Broadcasting

The disparity between how easy it is to watch a television program and how difficult it is to make one is truly staggering.

Outdoor shoots are often rushed, always difficult and dependent on a number of factors completely outside of any Human control (principally: the weather). Managing a live broadcast outdoors is a difficult job that only highly trained professionals are properly equipped to deal with.

Mistakes can cost huge sums of money and even jobs to be lost in an instant. As a result, it is of absolutely paramount importance that an outdoor shoot runs as smoothly as possible. It is not possible to control all the variables in this equation, therefore the factors that are controllable need to be handled with a great deal of care and attention. Continue reading

On The Air, In The Air Radios and Air Travel, an inseparable Mix

Radios are a Vital Tool for Air Travel. At London Heathrow airport, for example, three hundred companies employ some 80,000 people every day, whilst 65 million people leave from, arrive at, or pass through the airport. In the face of such staggering humanity, fast, efficient communication becomes paramount.

Medical personnel need to be notified quickly in case of an accident. Security guards must be able to respond and react to any potential threat as swiftly as possible. Other, daily issues such as reuniting lost children with their parents, locating missing luggage and the inspection of imported goods, must also be dealt with in a clear and professional manner.
