FM Broadcasting began in Alpine, New Jersey right on the top of the New Jersey Palisades. This was where Major Edwin Howard Armstrong, the inventor of FM radio built Alpine Tower, also known as “Armstrong Tower” in 1937. As the discoverer of frequency modulation “FM” in 1933, Armstrong spent many years experimenting on this discovery while working for RCA. Armstrong went through several legal battles throughout his thirteen years of FM discovery and research (and following his death). On April 10, 1938 Armstrong broadcasted for the first time on FM radio, from his experimental call sign W2XMN.
The FM radio was discovered after RCA’s former president David Sarnoff asked Armstrong to provide “a little black box” that could eliminate the static that plagued AM (amplitude modulation) broadcasting (FYBush). Ten years later, Armstrong discovered how to change the radio waves frequency. After Armstrong’s discovery and when David Sarnoff realized how great his discovery was. “This is not an ordinary invention," Sarnoff declared, “This is a revolution." (Amplifier) Sarnoff gave Armstrong RCA’s experimental television laboratory on top of the Empire State Building. Eventually, Sarnoff felt threatened by this discovery. RCA was slowly working on commercial television, and they did not want to spend extra money replacing radio equipment once Armstrong’s FM technology was accepted by the FCC (Federal Communications Commission). Armstrong was asked to remove his equipment from the laboratory and was told that RCA was going to continue to explore television development. They assured Armstrong that this was only temporary. However RCA never returned to working with Armstrong-they only worked against him in court when they decided to stop paying Armstrong his royalties to his patents. FM radio has changed a lot over the past decades. In the early 2000’s HD (high...

Choice & Major Companies

...David Yanich English 202 February 12, 2014 After doing research and realizing how much power and control major companies have in our world, I have come to this main question. How much choice do we really have when we want to purchase goods? Choice is something most people just assume they have when they are picking their cable company, choosing a bank, or even walking through your local food mart. The goal of this essay is to show that while at first glance choices may seem endless, but when you do a small amount of research you can quickly realize that most brands link back to the same parent company. The majority of foods, drinks, and health products we buy trace their way back to 10 major corporations. Society today has this false idea that they have a choice in what they buy at the grocery store. For example you may not like large soda companies and decide to not buy their products. But if you buy bottled water, sports drinks, energy drinks, or fruit juice chances are you are buying a brand from a soda producing parent company. Most retailers charge a fee to get products on the most visible shelves which keeps small companies away from your line of sight. This is because large consumer good companies have a special relationship with retailers. Like an “I’ll scratch your back if you scratch mine ideology”. Many of the products that you see on store shelves are direct competitors that are linked to the same company. “ConAgra sells six varieties of popcorn”......

Broadcasting of Am & Fm at Air

...1. Chapter 16, Harris CRYSTAL SETS TO SIDEBAND © Frank W. Harris 2006, REV 10 Chapter 16 ANCIENT MODULATION And other topics When I got back into ham radio 9 years ago, my ham friends told me that amplitude modulation (AM) was extinct. I was under the impression that SSB was the only mode of HF phone permitted. Later I learned that AM isn't actually illegal and there are a few diehards using AM on the 75 and 10 meter phone bands. I've also heard AM stations on 15 and 160 meters. In short, you might find a use for it. Besides, it's an interesting challenge to AM-modulate a transistorized transmitter. Homebuilt AM Back in the vacuum tube days many of us built our own transmitters and AM modulators. My first AM transmitter was a Heathkit DX-20. That was a 50 watt, CW, kit-built, vacuum tube transmitter to which I added a homebuilt AM modulator. Unlike SSB, AM could be added onto an existing CW transmitter. Rather than generate a low power AM signal and then amplify it with a linear amplifier, in the old days the usual method was to AM-modulate the final amplifier of the CW transmitter. On an oscilloscope, the hallmark of AM is that, when you are not speaking, the RF carrier wave runs continuously at an average power. That is, in AM the highest peak power and zero power only occur at the very highest voice peaks. Although I could see these transient peaks 2.

An Emprical Study on Fm Radio Adversiting

...AN EMPRICAL STUDY ON FM RADIO ADVERSITING Advertising of products and services is the route to rope in more customers and improve a company’s image. Radio is an effective, low-cost medium for advertising a company’s products. FM radio has today enabled advertisers to reach out to the audiences cost-effectively. In July 2005, the union cabinet approved the second phase of FM broadcasting in private sector, in which more emphasis was given to the growth of services than generating revenue for the government.

Now the Government expects to take a final view in two to three months on the third phase of expansion of FM radio and about 806 radio licences are expected to be issued and the Government plans to take FM radio to about 283 towns.

The advances that the radio had during the twentieth century been very important and life changing. When the radio was first invented it was a great success and it did the job it entailed. During the 20th Century the radio made some very important advances, they are advances ranging from transmute radio signals to amplifier levels, and FM radio to HD radio. All these advances made the radio what it is today. Transmatic radio signals are when a wireless receiver can transmit sound from over 2000 miles; this is a new way to send Morse code. FM Radio and HD radio advances came in the late twentieth century yet they were just as important; the FM radio came to solve the static problem that the AM radio was having.

The Metro Market Phenomenon 18% of all private FM stations are in Metro markets.
