What do the numbers on a radio station mean?
Megahertz means “millions of cycles per second,” so “91.5 megahertz” means that the transmitter at the radio station is oscillating at a frequency of 91,500,000 cycles per second.
Your FM (frequency modulated) radio can tune in to that specific frequency and give you clear reception of that station..
Is shortwave AM or FM?
Marine radio uses FM except for long range marine that uses SSB a derivative of AM. And SSB is still the main transmit mode choice by a huge population of amateur radio operators. And most shortwave (SW) broadcasting is still AM. AM radio is talk radio, that is, news, weather, traffic, sports and opinion.
What should I listen to on shortwave?
Specialized interests of shortwave listeners may include listening for shortwave utility, or “ute”, transmissions such as shipping, sailing, naval, aviation, or military signals, listening for intelligence signals (numbers stations), or tuning in amateur radio stations.

What is the purpose of UVB 76?
One former high-ranking European official and longtime student of Soviet jamming of Western radio stations, known to his fellow UVB-76 fans as “JM,” maintains that the Buzzer’s purpose is to transmit coded orders to military units within Russia, not to spies outside its borders.
HOW FAR CAN AM radio waves travel?
about 100 milesUseful daytime AM service is generally limited to a radius of no more than about 100 miles (162 km), even for the most powerful stations. However, during nighttime hours the AM signals can travel over hundreds of miles by reflection from the ionosphere, a phenomenon called “skywave” propagation.
Why is it called shortwave?
Shortwave radio received its name because the wavelengths in this band are shorter than 200 m (1,500 kHz) which marked the original upper limit of the medium frequency band first used for radio communications.

How do number stations work?
At their most basic, numbers stations are simply shortwave radio transmitters, generally operating between 3,000 and 30,000 kilohertz. They’re located in many, many countries, but no one knows just how numerous they are. They often transmit strings of numbers or numbers intoned by a computerized-sounding voice.
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.
Which is faster AM or FM?
FM uses a higher frequency range and a bigger bandwidth than AM. … Each FM station is allocated 150 kHz of bandwidth, which is 15 times that of an AM station. This means that an FM station can transmit 15 times as much information as an AM station and explains why music sounds so much better on FM.
What are number stations used for?
A numbers station is a shortwave radio station characterized by broadcasts of formatted numbers, which are believed to be addressed to intelligence officers operating in foreign countries.
Do spies use Morse code?
Spies Used Morse Code: The spies did not do any transmitting. They listened to Cuban shortwave transmissions in Morse code that gave them assignments.
Is UVB 76 still broadcasting?
On May 17, 2020, UVB-76 was interrupted again by a short third-party transmission.
Is AM radio dead?
Seems so retro, but it is still useful. Nevertheless, AM radio has been in decline for years, with many AM stations going out of business each year. … 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.
Which travels farther AM or FM?
Bottom line: AM signals tend to carry much farther (hundreds of miles, in some cases) but they are affected by weather and other atmospheric conditions. FM signals are usually much cleaner and do not get affected by static in the atmosphere, but they also cannot travel for long distances.
Do spies still use Morse code?
For Amateur Radio license requirements the FCC dropped the Morse Code requirement years ago. There is no current military use of Morse code. The Russian spies, recently arrested in the US, are keeping the The Code alive. …
Do numbers stations still exist?
Experts are confident that numbers stations do still exist, even if there are fewer of them. … Despite all the clues, no government has ever officially admitted or denied using numbers stations, nor have intelligence agencies.
Are there any shortwave stations left?
No wonder most of the analog shortwave transmitters sold today are DRM-capable or ready. In 2019 the BBC is still on shortwave and has large audiences in countries like Nigeria, having recently introduced new shortwave transmissions in additional languages.
How can I listen to UVB 76?
Tune the dial to 4625 kHz and you’ll hear a repetitive buzzing noise. This obnoxious station goes by the call sign UVB-76, but shortwave aficionados call it The Buzzer. The Buzzer has been blaring that tone since the early 1980s.
Can shortwave radio be traced?
Your signal can be tracked. It’s known as DF (Direction Finding) in the amateur radio world. … When it comes to an Amateur Radio license in the US, yes you can be tracked by that since it’s public record.
