How was early radio different from early telegraph system?
The difference is the telegraph required wires; the radio did not. But other then that, they were mostly the same.
What replaced the radio?
telegraph
First radio ever made?
Transmitter: a high voltage spark transmitter that emitted wideband radio noise. It was only useful for Morse Code telegraph messages.Receiver: detected pulses of radio signal using a device called a coherer, a glass tube full of iron filings that stuck together when a pulse arrived, the resulting drop in resistance tripped a relay which activated the sounder and a decoherer, a solenoid activated rubber mallet that tapped the cohererknocking the iron filings loose making it ready for the next radio pulse..
What is the electrical circuit for the radio in cars?
Car radio electrical circuits are as veried as the radios themselves. Certainly they have a lot of commonality, but each is unique. For a given unit, the manufacturer holds the circuit diagram. Other than that, about the only thing you could get your paws on would be a block diagram showing the general functional areas of the radio. If the question is pointed at the wiring diagram for the radio harness, that information is available from the car folks. Wire color and arranement differ from one unit to the next. A shop specializing in auto sound systems may be able to help.
What is a radio waves energy?
(The power of the radio transmitter) times (the length of time it continues to transmit)
What stores offer a radio transmitter compatible with an iPod?
Stores that offer a radio transmitter that are compatible with an iPod are as follows: WalMart, Target, Future Shop, The Source, Circuit City and Best Buy.
What came first radio or radio transmitter?
radio transmitter
How does microwaves travel to make a phone work?
They travel just like the radio waves that make your car radio work. They are sent from a transmitter - and picked up by your phone - the phone sends radio waves back to the transmitter to complete the circuit.
What types of waves are used in telegraphs to communicate in Morse code?
The basics of the telegraph include electricity, which is electromagnetic energy. In the modern era, we see the use of a telegraph key to complete an electric circuit, and the dots (dits) and dashes (dahs) are sent out through the air using a transmitter that generates electromagnetic waves. Some might call these radio waves, and this is wireless telegraphy.
What is a tank circuit used for?
A tank circuit is used in electronic circuits to store and transfer energy at a specific frequency. It consists of an inductor and a capacitor connected in parallel, which allows the circuit to resonate at a particular frequency. Tank circuits are commonly used in radio frequency amplifiers, oscillators, and tuning circuits.

When was Vakarel radio transmitter created?
Vakarel radio transmitter was created in 1937.
When was Ingøy radio transmitter created?

How do you make a radio transmitter on the Sims 2 Castaway?
by getting a transmitter and radio. then you press make radio into a transmitter. the transmitter and radio are both by the airplane in areoplane jungle, the transmitter is annoyingly hard to find as it is too small to see. The radio is big, however, and you should spot it right away. also ig you do this try using the transmitter on the volano or in crystal caves...
When was Solec Kujawski radio transmitter created?
Solec Kujawski radio transmitter was created in 1999.
