Radio communication is part of the flight training for FAA pilot certificates and it is also examined during the practical phase of your flight check. The FAA does not require an additional license for radio communication as other countries do. However some foreign countries do issue a restricted radio license to persons holding a FAA pilot certificate. You'll get more detailed information from your local aviation administration office or from the agency regulating radio communications in your country where you reside.

FAQ How Radio Communication Works Sound and radio waves are different phenomena. Sound consists of pressure variations in matter, such as air or water. Sound will not travel through a vacuum. Radio waves, like visible light, infrared, ultraviolet, X-rays and gamma rays, are electromagnetic waves that do travel through a vacuum. When you turn on a radio you hear sounds because the transmitter at the radio station has converted the sound waves into electromagnetic waves, which are then encoded onto an electromagnetic wave in the radio frequency range (generally in the range of 500-1600 kHz for AM stations, or 86-107 MHz for FM stations). Radio electromagnetic waves are used because they can travel very large distances through the atmosphere without being greatly attenuated due to scattering or absorption. Your radio receives the radio waves, decodes this information, and uses a speaker to change it back into a sound wave. An animated gif of this process is given below. START ANIMATION A sound wave is produced with a frequency of 5 Hz - 20 kHz.

Radio Communication with Extraterrestrials Radio messages travel at the speed of light and are relatively cheap to send. Round trip message time will still be inconvenient. If the nearest civilization is 100 light years away it will take 200 years to get the answer to a question. But just detecting a continuous transmission from another civilization would revolutionize our view of the universe. Where to look? Which stars of the hundred billion in our Galaxy? Sun-like stars may be a good starting point. We know life evolved around one of these. Which frequencies of the nearly infinite number of radio channels? ET's will try to make it easy and pick frequencies at or near those of astronomical interest. The "water hole" between the 21 cm line of hydrogen and the 18 cm line of OH (HOH = water) is a very quiet place in the radio spectrum. The signals must be obviously intelligent. A seqeunce of prime numbers is everybody's favorite probably with instructions on how to tune in on the interesting information. Since the travel time rules out "conversations", continous transmission of archival information may be most common.

This extract from the full article covers the general history and technical details of Ernst Alexanderson's development of alternator-transmitters, starting in 1906. General Electric Review , October, 1920, pages 794-797: Transoceanic Radio Communication By E. F. W. A LEXANDERSON C HIEF E NGINEER, R ADIO C ORPORATION OF A MERICA A certain spirit of romance has been directed in turn toward the initial feats of spanning the oceans by the sailing vessel, steamship, cable, radio, submarine, airplane, and airship. The passing of the romance attached to the earlier of these means has revealed us in possession of another thoroughly practical and established transoceanic type of communication. In the line of succession, radio now stands in midst of its transition stage. Skillful developmental work is hastening the process. The following article briefly reviews the highly successful Alexanderson system of telegraphic and telephonic radio. Each component piece of apparatus is described, its function outlined, and the operation of the whole equipment explained.E DITOR.

Exercise 7 Old Exams: Exam 1 Exam 2 Course presentation Course status Course targets The starting point is the planning of the physical transmission link with a radio system, which includes base-band and RF parts of the radio transceivers, antennas and feeders, and the radio path. After the course the student will have knowledge about typical radio communication systems and environments, impact of radio channel fading on information transmission, fading countermeasures and their performance, radio noise and equipment impairments, radio link budget and system planning. The main goal is to provide information for radio link budget calculations in radio link and network planning, so that the student is able to choose system solutions, which will guarantee that the radio communication system will fulfil given specifications. The radio link budget is a simple instrument for this purpose, but the determination of the gains and losses in the different terms of the budget will require profound knowledge of the performance of the different transmission methods. The application of it to system planning requires understanding of the interactions between the used transmission methods and algorithms.

Other topics Home page Announcing: Volume 4 "Clandestine Radio" Follow again the progress of new Volume For more details see the "Volume 4" Page Welcome to the home page of Louis Meulstee. He is the author of "WIRELESS FOR THE WARRIOR", a series of books devoted to the technical history and development of British Army radio communication. In this web site you will find basic technical descriptions and photographs of many vintage radio sets once used by the British Army. In addition, there are also posted numerous other subjects for example: line telegraph (the Fullerphone), Air-Sea rescue sets (Gibson Girl), a gallery with Soviet radios and various other subjects which are not really connected with British Army radio communications! Please note that the pages in this site are regularly updated and renewed. Especially the gallery section, which will be much more extended in the future. This will not be done on a scheduled base as I have a rather time consuming job (see below) and am NOT retired from the Army... Some time ago I added a page on the history of the company I work for ( Business Radio Solutions , a department of KPN Royal Dutch Telecom) entitled: Mobile Radio in the Netherlands.
