A particular radio station is selected on our radio set by adjusting the natural frequency of LC-circuitequal to the frequency of particular transmitting station.
Radio communication works on radio signals that are "beamed" into the air on a certain frequency. Frequency is a certain wavelength or band. The receiving equipment has to be set to receive the signal on the same frequency.
Aside from radio transmiters set up by humans. nearly every thing emenates high frequency radio waves.
FM or frequency modulation is a means to vary the frequency withing a set basic frequency and transmit it. FM radio demodulate the frequency extracting the signal that made the frequency shift at the source.
turn the radio on manually tuner in stations push the set button andnumber for station like 1 2 3 etc.
In most cases Manually tune to the desired station Hold button until display blinks - should be set.
If your car only has a radio, you will need to purchase an FM aux tuner. This will then plug into your iPod and you will tune your cars radio to the frequency that is set on the aux tuner.
The benefits of WiFi internet radio include the ability to hear radio stations that may be being broadcast from anywhere in the world. Conventional radio relies on radio waves that can be transmitted to a set distance on a set frequency band. WiFi internet radio requires just a stable internet connection.
By using a radio that is set at the frequency FM 104.7 one can listen to The Fish radio in Atlanta. One can also listen to this station through the internet using 'radio websites'.
An intercom works much like a private radio or phone system. Both units are set to the same frequency, and when you transmit the signal is only received by a unit on that frequency. It is possible for others, such as neighbors, to hear you talk if they happen to have a device set to the same frequency.
Guglielmo MarconiWhen Marconi built his first radio it was set to a specific frequency to match the receiver/transmitter that he was going to communicate with...variable tuning came later. The transmission was not voice, but "Click" code.The advent of commercial radio "Stations" and broad use brought about the need for variable tuning.So the FIRST radio would have had one hard frequency setting at a time.
1. Turn on the radio; 2. switch to the FM band; 3. set the frequency to the lowest possible; 4. press SET; 5. press SEL; 6. press memory button no. 1 five times. The radio will reset itself, all settings will be lost but it can now also receive the even frequency numbers.
