A broadcast band is a segment of the radio spectrum used for broadcasting.
Common name
Frequencies
Modulation
Frequency range
Notes
longwave
148.5–283.5 kHz
amplitude modulation (AM)
low frequency (LF)
Mostly used in Europe, North Africa, and Asia
AM radio (medium wave)
525–1606.5 kHz, 525–1705 kHz in N. America, Australia and the Philippines.
amplitude modulation (AM)
medium frequency (MF)
Usually speech and news, where a lower bandwidth will suffice; long range at night due to the ionosphere increasing in altitude
Shortwave
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 (TV)
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
Channels 2 through 6 are from 54–88 MHz (except 72–76 MHz).
FM radio
87.5–108 MHz, 76–90 MHz in Japan
Frequency Modulation (FM)
VHF band II
Usually music, due to the clarity and high bandwidth of FM. Relatively short range
VHF high (TV)
174–216 MHz
vestigial sideband modulation for analog video, and FM for analog audio; 8-VSB or OFDM for digital broadcast
VHF band III
Channels 7–13 use 174–216 MHz.
UHF (TV)
470–806 MHz
vestigial sideband modulation for analog video, and FM for analog audio; 8-VSB or OFDM for digital broadcast
ultra high frequency (UHF)
Channels 14–69 use 470–806 MHz, except for the radio astronomy band at 608–614 MHz where channel 37 would be
