What is MW and SW radio?

The name “shortwave” originated during the beginning of radio in the early 20th century, when the radio spectrum was divided into long wave (LW), medium wave (MW), and short wave (SW) bands based on the length of the wave. Early long-distance radio telegraphy used long waves, below 300 kilohertz (kHz).

What are the basic elements of DSP?

A DSP contains these key components:

  • Program Memory: Stores the programs the DSP will use to process data.
  • Data Memory: Stores the information to be processed.
  • Compute Engine: Performs the math processing, accessing the program from the Program Memory and the data from the Data Memory.

How do I get good FM radio reception?

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.

What should I look for in a shortwave radio?

Shortwave frequencies are usually considered those from the upper end of the AM broadcasting band, 1700 kHz, up to 30 MHz. The minimum frequency coverage you should look for is 540 kHz to 30 MHz. Most shortwave radios sold today also tune down to 150 kHz, covering the longwave band.

Is AM or FM Better?

With FM, the frequency (the number of times each second that the current changes direction) of the carrier signal is varied. FM signals have a great advantage over AM signals. Both signals are susceptible to slight changes in amplitude. With an AM broadcast, these changes result in static.

What is MW radio frequency?

Medium frequency (MF) is the ITU designation for radio frequencies (RF) in the range of 300 kilohertz (kHz) to 3 megahertz (MHz). Part of this band is the medium wave (MW) AM broadcast band. The MF band is also known as the hectometer band as the wavelengths range from ten to one hectometer (1000 to 100 m).

Are shortwave radios obsolete?

In North America and Europe, many of the major broadcasters have disappeared or minimized their presence. In fact, the BBC World Service no longer beams programming via shortwave to the Americas or most of Europe. “Shortwave is still significant in much of Africa, South Asia and parts of Latin America.”
