Ionosphere
Where are most of the worlds satellite radio receivers?
As of 2012 there are four satellite radio receivers recognized by the International Telecommunications Union. There are two European systems, which are DAB (digital audio broadcasting) system and the DRM (Digital Radio Mondiale). Then there are the Japanese ISDB-T and the U.S. HD-Radio (IBOC).
Can old radio receive FM stations?
The first FM radio station started broadcasting in the USA in 1937 although the frequencies we use today were not used until after the World War II. The popularity of FM broadcasting only became widespread in the 1970s, so many radios dating from before this period will probably not have the FM band. The only way to be sure is to check the dial or band switch.
Why do many radio stations around the world observe two minutes of silence in Late July 1937?
It commemorates the death of Marconi, one of the pioneers of radio (he was awarded the Nobel prize with Braun in 1909). On his death, in Italy, on 20 July 1937, radio stations around the world observed a two-minute silence.Piers Letcher (International Telecommunication Union)
What is ham radio?
Ham radio operators use two-way radio stations from their homes, cars, boats and outdoors to make hundreds of friends around town and around the world. They communicate with each other using voice, computers, and Morse code. Some hams bounce their signals off the upper regions of the atmosphere, so they can talk with hams on the other side of the world. Other hams use satellites. Many use hand-held radios that fit in their pockets.
How many stations are in the world?
around 30,000
Where do the images A of weather systems on the television come from?
The images of weather systems on television typically come from weather satellites in space, radar systems on the ground, and weather stations located around the world. These images are captured, processed, and then transmitted to television stations or weather forecasting centers for broadcasting.
How many weather stations are in the world?
around 30,000
Why is that radio stations such as the British Broadcasting Corporation world service change the frequency at which they broadcast to Africa with the period of the day?
Radio stations such as the BBC World Service change the frequency at which they broadcast to Africa with the period of the day, because propagation effects due to the Ionosphere are different depending on the altitude of the Ionosphere, which depends on the sunlight shining on it. The lower the frequency of a radio signal, the more prone it is to bounce off of the Ionosphere and the Earth. This is known as skip, and it increases the distance the signal can travel. This is why low frequency Ham Radio signals, particularly in the 80 metre band, can travel half way around the world at night.
What has the author B B BABANI written?
B. B. BABANI has written: 'World's short medium and long wave FM and TV broadcasting stations listing'
What does the acronym NBC stand for?
Whilst it's true that the acronym WNBC stands for W National Broadcasting Company. The W is NOT a prefix indicating west of the Mississippi but, rather and counter-intuitively, EAST of the Mississippi. In 1912, several countries attended a conference to discuss international radiotelegraphs. One of the things that came out of that meeting was the assignment or specific letters to identify each country’s radio and television signals. The United States was given the letters W, K, N, and A. The letters ‘N’ and ‘A’ were given to military stations, but ‘K’ and ‘W’ were assigned out for commercial use. Radio stations east of the Mississippi River had to start their stations with ‘W’, and stations west of the Mississippi with ‘K’. There is some discrepancy though since radio stations that already existed before this rule was put in place weren’t required to change their name.
Can you hear radios from other countries?
Yes, my dad has an iPhone app that came with his BMW and he can listen to radio from Germany, Thailand, US, pretty much anywhere.Answer:The hobby of attempting to receive radio signals form distant stations directly without local rebraodcasters is known as DXing. It used to be popular, Due to the way that signals could skip off the ionosphere signals could be heard half way around the world on AM broadcasts under ideal condition. The specific task of hearing stations from other countries was simplified for some residents in cities such as Detroit where the Windsor Ontario Stations could be closer than the American ones.
Why do you feel emotional?
Emotions are neural signals that tell the brain about the world around us. These signals tell the brain how to respond to the stimuli.
Since broadcasting How far have tv signals gone into space?
The world has been broadcasting TV signals since the 1920s. That has given the earliest signals about 80 years to travel away from earth, so that means they have travelled up to 80 light years. That is about 500,000,000,000,000 miles (give or take a few million miles). That radius is enough to encompass up to 100 stars so the signals will have passed quite a few planets so far. By the time the signals reach these planets, the signals are probably far too weak to be detected above the radio noise of the universe so it is unlikely that any other life forms are watching our television programs from decades ago

How do you use a world band radio to listen to the USA when overseas?
To make sure your world band radio can properly receive signals from U.S. radio stations, make sure the antenna is fully extended. Turning the tuning dial will allow you to browse available stations. Keep in mind that the selection of world band radio stations available changes frequently, so you might not be able to find the exact station you desire.
What news stations will show scenes from various combats around the world?
Most news stations will show images and scenes from combat events around the world. For instance, FOX News and CNBC offer coverage on the conflicts in Afghanistan, Libya, and elsewhere.
