  Radio-Electronics.Com :: Radio Receiver Sensitivity
The two main requirements of any radio receiver are that it should be able to separate one station from another, i.e.
These all use the fact that the limiting factor of the sensitivity of a radio receiver is not the level of amplification available, but the levels of noise that are present, whether they are generated within the radio receiver or outside it.
Normally radio receivers are designed such that the internally generated noise is much lower than any received noise, even for the quietest locations.

  radio. The Columbia Encyclopedia, Sixth Edition. 2001-05
A radio wave acts as a carrier of information-bearing signals; the information may be encoded directly on the wave by periodically interrupting its transmission (as in dot-and-dash telegraphy) or impressed on it by a process called modulation.
In both radio and television receivers, once the basic signals have been separated from the carrier wave they are fed to a loudspeaker or a display device (usually a cathode-ray tube), where they are converted into sound and visual images, respectively.
Radio is based on the studies of James Clerk Maxwell, who developed the mathematical theory of electromagnetic waves, and Heinrich Hertz, who devised an apparatus for generating and detecting them.

Radio can be incredibly simple, and around the turn of the century this simplicity made early experimentation possible for just about anyone.
A typical baby monitor, with the receiver on the left and the transmitter on the right: The transmitter sits in the baby's room and is essentially a mini "radio station." The parents carry the receiver around the house to listen to the baby.
FM radio signals are operating in the range of 100,000,000 hertz, so 101.5 on the FM dial is a transmitter generating a sine wave at 101,500,000 cycles per second.

 Receiver (radio) - Wikipedia, the free encyclopedia
A radio receiver is a real world example of a receiver in the information theoretic sense.
The receiver is generally the nerve centre of a sophisticated home-theatre system providing selectable inputs for a number of different audio components like turntables, compact-disc players, and tape decks and video components like video-cassette recorders, DVD players, video-game systems, and televisions.
Self-powered radios, such as clockwork radios are used in developing nations or as part of an emergency preparedness kit.

 Molecular Expressions: Electricity and Magnetism - Interactive Java Tutorials: Radio Receiver
Variable capacitors are used with inductor coils in tuning circuits of radios, television sets, and a number of other devices that must isolate electromagnetic radiation of selected frequencies.
Transmitted radio waves cause an induced current to flow in the antenna through the primary inductor coil of the transformer to ground.
This radio circuit therefore, is tuned by adjusting the capacitance of the variable capacitor to equalize the inductive and capacitive reactance for the desired resonant frequency, or in other words, to tune in the desired radio frequency.

 Crystal radio receiver - Wikipedia, the free encyclopedia
Crystal radio was invented by a long, vague chain of discoveries in the late 1800's that culminated into the first practical kind of radio receiver in the early 1900's; and constitutes the origin of the field of electronics.
While there were a number of earlier experiments with radio broadcasts to the general public, most historians consider the Autumn of 1920 to be the beginning of radio broadcasting for entertainment purposes.
The crystal radio did not require batteries, but it did require the user to purchase a commercially made set of headphones (or telephone receivers as they were called in those days), since that accessory was not suitable for home construction.

 Radio receiver design - Wikipedia, the free encyclopedia
In the Direct conversion receiver the signals from the aerial pass through a band pass filter, and an amplifier before reaching a non-linear mixer where they are mixed with a signal from a local oscillator which is tuned to the carrier wave frequency of an AM or SSB transmitter.
Note that the radio lacks a AGC loop, and that the IF amplifier has a very high gain and is driven into clipping.
To make a good FM receiver a large number of RF amps which are driven into limiting are required to create a receiver which can take advantage of the capture effect, one of the biggest advantages of FM.

We’re pleased to announce that the Receiver Shopping List, which for many years was a printed booklet from Radio Netherlands, then a Web feature, has been moved to its new home on the recently relaunched website of the Medium Wave Circle.
Changing editorial priorities and budget cuts meant that Radio Netherlands was unable to continue supporting this feature, and it seemed logical to hand over the material to a hobby club.
Although it is about five years since the last review was written, some of the receivers featured are still available either new or secondhand.
