What radio signals can be amplified?

In 1907, American inventor Lee De Forest introduced his patented Audion signal detector–which allowed radio frequency signals to be amplified dramatically. Another American inventor, Edwin Armstrong, developed the superheterodyne circuit in 1918, and in 1933 discovered how FM broadcasts could be produced.

How can I make my radio signal stronger?

Try outdoor antennas.

1. Make sure it is outdoors, roof mounted, or in the attic.
2. Most roof antennas will give you radio reception similar to a car radio, or often better.
3. Try repurposing a TV antenna you already have; use an FM splitter to use it on your radio.
4. Consider an omnidirectional radio antenna.

How can I improve my FM radio signal strength?

Get a new antenna. Switching from an indoor to an outdoor antenna can greatly improve FM reception. If you have a directional antenna, try switching to an omnidirectional antenna, or vice versa. Directional antennas can pick up stations from farther away, but omnidirectional antennas work well for closer stations.

Which is better AM or FM?

The difference in the way AM and FM radio signals are encoded means differences in sound quality, performance, and broadcast range between the two types of station. This explains why FM stations sound better than AM stations, but AM stations can be heard from further away.

What is the advantage of AM over FM?

The main advantages of FM over AM are: Improved signal to noise ratio (about 25dB) w.r.t. to man made interference. Smaller geographical interference between neighboring stations. Less radiated power.

What are the disadvantages of AM radio?

The major disadvantage of AM is that the signal is affected by electrical storms and other radio frequency interference. Also, although the radio transmitters can transmit sound waves of frequency up to 15 kHz, most receivers are able to reproduce frequencies only up to 5kHz or less.

Why is sound immunity better in FM vs AM?

FM signal is having fixed amplitude and phase and frequency is variable. Noise is generally uniformly spread across the spectrum and varies randomly in amplitude. The change in amplitude can modulate the signal and can be picked up in an AM system. So FM is more immune to noise.

Which wave is less immune to noise?

Because the frequency of a radio wave is less vulnerable to noise than the amplitude, FM was originally introduced to reduce noise and improve the quality of radio reception. In order to accomplish this, FM radio signals have bandwidth several times that of AM signals. Bandwidths six times or larger are common.

What is FM immunity?

Consequently, for safety reasons, VOR and ILS receivers in aircraft are now required to be protected against potential interference from VHF broadcast transmissions. This entails the use of FM (Frequency Modulation) immune VHF equipment through the modification of existing equipment or re-equipage.

How do aircraft radios work?

An aircraft uses a range of radio frequencies to navigate to its destination and communicate with air traffic control. To do this successfully, the onboard radio equipment uses different types and sizes of antennas, each designed for their own frequency band. These VHF frequencies have a line of sight capability.
