The definition of what it is, is actually in your question. It's a receiver that operates in the radio frequency spectrum. Anything that has a transmitter is said to transmit in radio frequency or `RF`. The term radio is short for radiotelegraphy, which has become generic over the years.

Where does the radio frequency start? Technically, it' at 10,000 hz and higher. That's not to say that there's lower frequency transmitters (The U.S. Gov't uses 2 hz. to reach our submarines when they're under water, but that's more of an exception than the rule. The radio frequency spectrum can extend into the gigahertz range for things such as satellite communications, and as our technology advances, we could eventually see frequencies in the teraherts.

So a radio frequency receiver is anything that will receive a a frequency in the radio frequency range.

Hope this helps,

It can get pretty complicated. You need a radio receiver, and you need to be close enough to the transmitter of the station you want to receive. Also, you need to know that station's transmit frequency, and tune your receiver to that frequency.

You need a VHF radio antenna, a VHF radio receiver and of course a station broadcasting on the VHF frequency.

A radio receiver is an electronic device that receives radio wave/signal and convert the information carried by them to a usuable form through speaker. The principal functions of a radio receiver are frequency selection, amplification and detection of signals which are been convert back to its original form through the help of radio speaker.

Most FM receivers use 10.7 MHz as the IF.

You would probably be using a radio receiver. It is possible you'd be using a transceiver, which combines the functions of a transmitter and a receiver.

A radio telescope has two basic components, a large radio antenna and a radio receiver. It is used to detect radio-frequency radiation emitted by objects in space.

to shift the frequency of information signal ,at the frequency domain to a higher frequency the information can be transmitted to the receiver.

The "tuning capacitor" in a radio is involved in determining the frequency of an oscillator somewhere in the radio. As that capacitance is varied, the frequency of the oscillator changes. If the radio device is a transmitter, then the frequency on which it's transmitting changes. If the device is a radio receiver, then the frequency of the internal "local oscillator" determines the frequency that will be selected, out of everything coming down from the antenna, and then processed, detected, amplified, and filtered, for your listening pleasure.

RF as in Radio Frequency, probably something meant to go between an antenna and a transmitter/receiver.

The most common IF in consumer-grade FM radios is 10.7 MHz .

Because in radio communication a signal is specified by its frequency, In AM the carrier frequency is fixed.. we cant limit or manipulate it as it will might switch us to another carrier in the atmosphere... manipulating however amplitude (as in FM) doesn't switch us to another channel... so remember in radio communication signal is specified by its frequency whether FM or AM..

RF stands for Radio Frequency, magnetic waves radiate out of the transmitting antenna and are picked up or recovered by the receiving antenna at the receiver.
