Can you communicate with a short wave radio? Shortwave lets you listen to emergency broadcasts, talk locally, and even communicate around the world. It is relatively inexpensive and easy to get the equipment you need to stay informed during an emergency.
What is shortwave communication?
Shortwave radio is radio transmission using shortwave (SW) radio frequencies. Thus shortwave radio can be used for very long distance communication, in contrast to radio waves of higher frequency which travel in straight lines (line-of-sight propagation) and are limited by the visual horizon, about 64 km (40 miles).
Is shortwave radio still available?
It was widely used during the 20th century, when virtually every country had several stations broadcasting via shortwave to the international public. Some of these are still operational, such as the BBC World Service, Voice of America and Radio France Internationale, among many others.
What can I listen to on shortwave radio?
Other shortwave radio stations US customers might listen to include:
Why is shortwave better at night?
As it turns out, the ionosphere reflects certain frequencies of radio waves. So the waves bounce between the ground and the ionosphere and make their way around the planet. You can pick up some radio stations better at night because the reflection characteristics of the ionosphere are better at night.

Are shortwave radios obsolete?
Answer: Absolutely! Regular shortwave radio listeners already know the answer to this question. Sure, the landscape of the shortwaves is changing, but it's such a vast landscape that, even with a few major players dropping out, there is still so much to hear and appreciate.
Why would I need a shortwave radio?
Over the years, people have relied on shortwave radio for broadcasting voice and news to listeners over massive areas – even spanning continents. Other uses include over-the-horizon radar, two-way international communication, and diplomatic communication.
What are shortwave radios good for?
Besides their use in international broadcasting, shortwave radio frequencies and techniques are utilized to relay telephone and telegraph communications over great distances. Amateur radio stations and portable two-way radios also operate at shortwave frequencies.
What frequencies are considered shortwave?
High Frequency Broadcasting (HF), also known as Shortwave Broadcasting, is a radio service licensed by the FCC to operate between 5,950 kHz and 26,100 kHz. This is an international broadcast service where transmissions are intended to be received by the general public in foreign countries.
Who uses shortwave radio?
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. Twenty years after the first big blow to shortwave, this frequency band and its potential is being revisited.
Is a ham radio a shortwave radio?
Shortwave radio operates on all frequencies including all of the frequencies that ham radios operate on. On the other hand, Ham radio operates on limited frequencies only with licenses.
What is the most powerful radio station?
XERA called itself "the world's most powerful broadcasting station" and Variety magazine claimed that it could be heard in New York City.
Why is AM radio bad at night?
At night there is less upper layer ionization, so the AM signal refracts off the upper layers, causing the signal to skip hundreds or even thousands of miles. This causes interference to other stations.
Can a person hear radio waves?
Yes, humans, under special circumstances, can hear radio-frequency pulses in the range of 2.4MHz to 10GHz (corresponding to radio frequencies and microwave) as buzzes, clocks, hiss or knocking at apparent auditory frequencies of 5kHz and higher (very high-pitched).
Is shortwave radio worth listening to?
Question: So is there anything to listen to? Answer: Absolutely! Regular shortwave radio listeners already know the answer to this question. Sure, the landscape of the shortwaves is changing, but it's such a vast landscape that, even with a few major players dropping out, there is still so much to hear and appreciate.
How can I get better reception on my shortwave radio?
How long is a shortwave antenna?
The length of the antenna needs to agree with the length of the longest radio waves that you want to receive. Shortwave broadcasters use frequencies that are from about 50 to about 400 feet long, and an effective antenna needs to be at least one-fourth of that length — and one-half is much better.
Is shortwave listening dead?
In fact, the BBC World Service no longer beams programming via shortwave to the Americas or most of Europe. “There has been a massive decline in shortwave listenership, especially in Europe and North America,” said Andy Sennitt. “Shortwave is still significant in much of Africa, South Asia and parts of Latin America.”
Can you play music on shortwave radio?
But they do broadcast very, very accurate time signals. That time can be heard on shortwave radio 24/7. Early on, WWV focused on experimental broadcasts (think Victrola concerts that wowed early radio users).
Is a shortwave radio fun?
So why bother with shortwave? It's easy and cheap -- and fun. You can hear and learn things that you would never find even if you work your search engine like a mule. From Swaziland to Paris to Havana, shortwave broadcasters can surprise an adventurous listener more than any MP3 playlist.
What is the difference between long and short radio waves?
Longwave moves along the ground at a certain power and moves across in a linear line. In contrast, shortwave link with the atmosphere and reflects the earth's path to move in a curve. Longwave comes back to the earth after it gets into the ionosphere. Shortwave too interrelates with the ionosphere.
What is shortwave therapy?
“Shortwave diathermy uses high-frequency electromagnetic energy to generate heat. It may be applied in pulsed or continuous energy waves. It has been used to treat pain from kidney stones, and pelvic inflammatory disease. It's commonly used for conditions that cause pain and muscle spasms.”
Can you listen to police on shortwave?
The Shortwave or HF spectrum covers 3 to 30 MHz. Police, Emergency, Fire, etc. radios are in the VHF and UHF spectrum. They also use FM and digital techniques not possible for an old AM radio to decode.
Can ham radio pick up shortwave?
Shortwave listening includes listening to anything in this range, including broadcast shortwave. CB and Ham Radio in the US allow receiving and transmitting on specific ranges of frequencies based on laws and rules formulated and enforced by the FCC.
Can you use a CB antenna for a ham radio?
Yes you can put a CB whip and a ham whip on the same vehicle as shown in the photo, and no, they won't "cancel each other out." Remember that hams can operate on many different bands, from 1.8 mHz to something like 2,300 mHz, and the antennas will vary all over the place as to length.
How far can a 50000 watt FM radio station reach?
The most powerful 50,000 watt AM radio stations can be heard within a hundred miles or further in the daytime.
What are the 5 classes of radio time?
Classes for U.S. AM Broadcast Stations
How far can Hf travel?
But the real advantage of HF is skywave propagation, where a single link can span distances as great as 3,000 km (a little less than 1,900 miles). Skywave propagation occurs when the radio wave is refracted (bent) in the uppermost layer of the atmosphere, called the ionosphere.
Which travels farther AM or FM?
Although AM waves can be received at greater distances than FM waves, FM. Furthermore, FM has much better sound than AM because AM has a different frequency and wavelength than FM. AM stations broadcast on frequencies of between 535 and 1605 kilohertz. The FM band extends from 88 to 108 megahertz.
How far does a FM radio signal travel?
VHF radio waves usually do not travel far beyond the visual horizon, so reception distances for FM stations are typically limited to 30–40 miles (50–60 km).
