Frequency Radio Broadcast Stations (FCC) State/city Radio Broadcast Stations (FCC) Frequency "United States Assignments" Arrangement between the United States of America, Canada, Cuba, the Dominican Republic, Haiti, and Mexico, comprising recommendations of the North American Regional Radio-Engineering Meeting (supplemental to North American ...
AM broadcasting is radio broadcasting using amplitude modulation (AM) transmissions. 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.
In the United States, the normal Federal Communications Commission (FCC) practice for station applications on the standard AM band frequencies had been to individually process requests. For the expanded band, the Commission decided to allocate the entire band at once on a nationwide basis, after evaluating all of the stations which notified the ...
Because the AM broadcast band developed before technology suitable for directional antennas, there are numerous exceptions, such as the US use of 800 (kHz) and 900 non-directionally in Alaska, limited to 5 kW at night; and 1050 and 1220, directionally, in the continental US, and without time limits; each of these being assigned to specific ...

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
Broadcast frequencies: Longwave AM Radio = 148.5 kHz – 283.5 kHz (LF) Mediumwave AM Radio = 520 kHz – 1700 kHz (MF) Shortwave AM Radio = 3 MHz – 30 MHz (HF) Designations for television and FM radio broadcast frequencies vary between countries, see Television channel frequencies and FM broadcast 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).
