  2. AM broadcasting - Wikipedia

    en.wikipedia.org/wiki/AM_broadcasting

    AM broadcasts are used on several frequency bands. The allocation of these bands is governed by the ITU's Radio Regulations and, on the national level, by each country's telecommunications administration (the FCC in the U.S., for example) subject to international agreements. The frequency ranges given here are those that are allocated to stations.

    Multiple; see Shortwave bands: Mostly AM and single-sideband (SSB) modes high frequency (HF) Very long range through "skipping". Standard time frequencies can be heard here. VHF low 54–88 MHz: vestigial sideband modulation for analog video, and FM for analog audio; 8-VSB or OFDM for digital broadcast very high frequency (VHF) band I

  4. Radio spectrum - Wikipedia

    en.wikipedia.org/wiki/Radio_spectrum

    A radio band is a small frequency band (a contiguous section of the range of the radio spectrum) in which channels are usually used or set aside for the same purpose. To prevent interference and allow for efficient use of the radio spectrum, similar services are allocated in bands.

  5. AM expanded band - Wikipedia

    en.wikipedia.org/wiki/AM_expanded_band

    The extended mediumwave broadcast band, commonly known as the AM expanded band, refers to the broadcast station frequency assignments immediately above the earlier upper limits of 1600 kHz in International Telecommunication Union (ITU) Region 2 (the Americas), and 1602 kHz in ITU Regions 1 (Europe, northern Asia and Africa) and 3 (southern Asia and Oceania).

  6. Medium frequency - Wikipedia

    en.wikipedia.org/wiki/Medium_frequency

    Medium frequency (MF) is the ITU designation [1] [2] 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 hectometers (1000 to 100 m).

  7. Medium wave - Wikipedia

    en.wikipedia.org/wiki/Medium_wave

    Medium wave (MW) is a part of the medium frequency (MF) radio band used mainly for AM radio broadcasting. The spectrum provides about 120 channels with more limited sound quality than FM stations on the FM broadcast band. During the daytime, reception is usually limited to more local stations, though this is dependent on the signal conditions ...

  8. List of AM stereo radio stations - Wikipedia

    en.wikipedia.org/wiki/List_of_AM_stereo_radio...

    The following is a list of AM radio stations transmitting in C-QUAM stereo throughout the world, which can be sorted by their call signs, frequencies, cities of license, country of origin, licensees, and programming formats. Japanese stations sometimes omit the JO prefix in favor of just the last two letters of their callsigns. Australia issues ...

  9. Amateur radio frequency allocations - Wikipedia

    The nominal "17 m" band actually covers 16.6–16.5 m. The nominal "15 m" band actually ranges from 14.28–13.98 m. By common sense, the "15 m" band ought to be called "14 m", but that name has been in longtime use for a shortwave broadcast band. 80 metres or 80 / 75 meters – 3 500–4 000 kHz – 85.65–74.95 m actual
