Why Can’t I Use a Radio or a Phone on an Aeroplane?

The real reason is that the signals generated by your radio receiver (yes, it generates signals as well as receives them) can interfere with the aeroplane’s navigation equipment.

 

In an article for ‘The Straight Dope’, published in 1987, Cecil Adams (who ran a similar, but far superior, column to this one) explained it far better than I could. He said,

 

“Most modern receivers use something called a “local oscillator,” which is sort of an internal transmitter. The oscillator generates signal A, which is mixed with the somewhat raw incoming signal B to produce nice, easy-to-work-with signal C. There’s usually some sort of shielding around the oscillator, but it’s not always effective and sometimes errant signals leak out to make life difficult for other radio equipment nearby. If the other equipment happens to be an aircraft navigation device, somebody could wind up digging furrows with a $25 million plow. So do your bit for air safety and bring a tape player instead.” Continue reading

How does bone conduction work?

Bone conduction headphones (commonly referred to as ‘Bonephones’) are actually really clever. In order to best explain how they work, I’ll need to take you on a journey into the Human ear…

No, not literally. That would be disgusting.

OK, so you know how sound travels through the air? Surely you must have done that science experiment at school where you hear sound disappearing into an airless vacuum? Yup, it’s just like that. 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

Gupta: Cell phones, brain tumors and a wired earpiece

So to continue my run of content on this blog, I have decided to share one of our favourite posts this week. I used to be hesitant to add it to the blog because I actually didn’t wish to offend the initial writer, but I trust he/she is glad that I enjoyed reading their work and planned to share it with my readers.

By Dr. Sanjay Gupta, Chief Medical Correspondent

Just about every time I use a cell phone, I plug in my wired earpiece first. Having discussed the use of earpieces on several news shows, people expect to see me using one. If I am walking around the CNN studios, my colleagues often comment on it. In airports, people will stop me in the rare cases I forget to use the earpiece, and remind me about it. Perhaps, they are intrigued because I am a neurosurgeon who openly shows some concern about cell phones. Continue reading

Hotel Radio Communication

The tourism industry is a big one, with various holiday seasons bringing in huge revenues around the world, year in, year out. In some cases, tourism profits are actually vital to the survival of small towns and resort areas, as well as major factors in the host country’s GDP.

Approximately 30 Million people visit the UK from all over the world each year (and we don’t even get nice weather!). Drawn to our many sites of cultural interest, even more of historical interest, or just a slice on English country life, these tourists are actually a considerable part of our economy.
