Does the BBC still broadcast on shortwave?
BBC World Service at 80: A lifetime of shortwave. The BBC World Service – which marks its 80th birthday on Wednesday – was broadcast only on shortwave back in 1932. Today, audiences on FM, digital radio and the internet are growing fast while shortwave is in decline, but for millions it remains a lifeline.
Is AM radio shortwave?
It was the first method developed for making audio radio transmissions, and is still used worldwide, primarily for medium wave (also known as “AM band”) transmissions, but also on the longwave and shortwave radio bands. The earliest experimental AM transmissions began in the early 1900s.
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 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.
Is UVB 76 still broadcasting?
The radio signal that occupies 4625 kHz has reportedly been broadcasting since the late 1970s. The earliest known recording of it is dated 1982. … Instead of shutting down with the fall of communism in Russia, UVB-76 became even more active.
Why do radio stations reduce power at night?
Most AM radio stations are required by the FCC’s rules to reduce their power or cease operating at night in order to avoid interference to other AM stations. … However, during nighttime hours the AM signals can travel over hundreds of miles by reflection from the ionosphere, a phenomenon called “skywave” propagation.
Are Number Stations real?

What is the number station?
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. … The first known use of numbers stations was during World War I, with the numbers transmitted in Morse code.
What can I listen to on shortwave radio?

How much does a shortwave radio cost?
Shortwave prices range from about $50 for a compact portable to $2,000 or more for one of the large tabletop sets.
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 often transmit strings of numbers or numbers intoned by a computerized-sounding voice. Others send broadcasts via Morse code or they just emit various types of noise.
What is the Swedish Rhapsody?
