Why is my car AM radio reception poor?
Check Your Antenna Connections One of the most common causes of poor car radio reception is a poor antenna connection.
If the antenna cable is poorly seated in your head unit, or any of the connections are loose, worn, or corroded, you’ll often find it difficult to tune into your favorite station..
Why do aircraft use AM radio?
Aviation voice radios use VHF AM. AM is used so that multiple stations on the same channel can be received. (Use of FM would result in stronger stations blocking out reception of weaker stations due to FM’s capture effect).
Does shortwave radio still exist?
At the moment the major shortwave broadcasters are BBC, Voice of America, All India Radio, China Radio International, Radio Japan, Radio Romania, KBS Korea and Voice of Turkey and many more. … No wonder most of the analog shortwave transmitters sold today are DRM-capable or ready.

Why is AM radio bad at night?
At night medium wave radio signals can travel much further than during the day. This means your radio is able to receive more radio channels either using the same frequency as the service you are listening to or adjacent to that frequency.
What is the point of AM radio?
AM stands for “Amplitude Modulation”, as AM radio signals vary their amplitude to adapt to the sound information that is being broadcasted through the wavelengths. While changes in amplitude occur on FM radio as well, they are more noticeable in AM radio because they result in audible static.
Are old radios dangerous?
You should be very wary of all unrestored old electrical devices such as kitchen appliances, fans, signs, and radios. Cords become frayed with age, insulation breaks down on various parts and switches wear out. … Antique Radios may also contain hazardous substances, see Antique Radios and Asbestos.
How do you fix AM radio static?
Fixing AM/FM Car Radio StaticMake sure the problem isn’t external.Check the car radio ground connection.Unplug the radio antenna and check if the sound is still there.Check if moving the antenna wire removes static.Check if moving other wires removes the static.
Is broadcasting AM radio legal?
UNLICENSED LEGAL AM The legal limit for AM broadcasting is 100 milliwatts, with a maximum antenna length of about 10 feet (this is highlighted in Part 15 as well). … A note about Part 15 – it does not require that you use a transmitter that has been type-accepted, so it is “legal” to use a homemade transmitter or a kit.
Is AM radio going away?
Nevertheless, AM radio has been in decline for years, with many AM stations going out of business each year. Now there are only 4,684 left as of the end of 2015.
Why is AM radio so bad?
AM stands for Amplitude Modulation and has poorer sound quality compared with FM, but it is cheaper to transmit and can be sent over long distances — especially at night. The lower frequencies of the band we use for AM signals creates a wavelength that is extremely large.
Why did AM radio die out?
The decline in AM audio was due more to regulation than to method of modulation. One aspect of radio not understood by most listeners is the concept of occupied bandwidth, or the amount of spectrum that a station uses to transmit its signal.
