What was used to broadcast from the moon during the Apollo 11 mission?
The LM had an antenna array that could beam signals to Earth. When the astronauts were out on EVA, their suits had radios which beamed signals to the LM, which in turn sent the signals to Earth. The LM acted as relay between the Earth and the suit radios.
How did radios affect Popular culture?
Radios were first used to broadcast system for emergency use, then eventually use to broadcast baseball, presidential speeches, and so fourth.
How do XM radios work exactly?
XM radios use signals transmitted by satellites in order to broadcast. A signal is broadcast from the ground station and sent to one of two XM satellites that then are able to broadcast the signal to all the receivers owned by XM customers on the ground. The satellites take the signal they are sent, which is basically a mass of encoded data, and descramble the audio as well as the encrypted information with it which includes such things as the song title, artist, and genre in order to send them to the personal receivers in the correct format.
What is the function of RF tuner?
An RF tuner is a device that receives radio frequency signals and converts them into audio or video signals for playback. It filters and demodulates the incoming signals, allowing users to access various broadcast channels, such as television or radio. RF tuners are commonly found in televisions, radios, and other multimedia devices, enabling them to tune into specific frequencies for content delivery.
Do crystal radio sets still work now that everything has gone digital?
Yes because only television signals from some stations have gone digital. Crystal radios will pick up stations broadcasting on the A.M. broadcast band (540k to 1600K). These signals are amplitude modulated and crystal radios pick these up really well. You could also use them for Shortwave and pick up some stations. Am, FM and shortwave are still not digital.
What is a bilinear amplifier?
it amplifies both the incomeing and outgoing signals on CB radios
What is the highest and lowest radio signals that your radio signals that your radio can pick up for AM and FM?
Radio signals have several characteristics ... wavelength, field strength, amplitude, advertising cost,popularity, frequency, etc. The question doesn't specify which characteristic it wants measured in orderto name the "highest" and "lowest".We'll assume it's referring to the frequency of the various radio signals.In the USA, commercial AM broadcast stations all have carrier frequencies between 0.55 MHz and 1.7 MHz.Typical consumer AM radios are designed to operate across that range.In the USA, commercial FM broadcast stations all have carrier frequencies between 88 MHz and 108 MHz.Typical consumer FM radios are designed to operate across that range.
How do airplanes communicate?
Most planes have VHF radios. Military planes have UHF radios, and some planes have satellite communications.
How people communicate using radios?
Morris code, tele-graph, light signals on ships.
How do boats communicate with one another?
They have radios stationed in all boats. <><><> Well, there are radios in MOST ships, and many boats. Besides radio, ships communicate with each other by horn signals. There is a standard set of signals that indicate actions that a ship is about to take.
Was tv made before truck radios?
The earliest production radios for automobiles (including trucks) were introduced by Motorola in 1930. While the fundamental inventions necessary for television had been made by that time, they did not appear in production (electronic, as opposed to electromechanical) television receivers until the mid-1930s. In the US, broadcast television signals were not standardized until 1941, when the first commercial broadcast television licenses were issued.If you mean two-way radios for trucks, then it's practically a tie. Two-way radios were being installed in fire trucks as early as 1938--exactly the same time that television was being introduced.This question could be debated endlessly, since it really depends on what form of experimental television you would accept as the starting point.
What is the purpose of a marine band radio?
Marine band radios are two-way radios which are used either in a military setting or by officers for easy communication. The purpose of these radios is to get a greater range of communcation.
