Band II is the range of radio
frequencies
Frequency is the number of occurrences of a repeating event per unit of time. It is also occasionally referred to as ''temporal frequency'' for clarity, and is distinct from ''angular frequency''. Frequency is measured in hertz (Hz) which is e ...

FM radio broadcasting.
Broadcast television
Usage in Russia and in other former members of OIRT
In the former Soviet Union and other countries-members of
OIRT, frequencies from 76 MHz to 100 MHz were designated for broadcast television usage.
Considering 8 MHz channel bandwidth used by the Russian analog television system (
System D), the following television channels had been defined:
Broadcast television channels 1 and 2 are assigned to
VHF I band, channels 6 to 12 are assigned to
VHF III band.
Starting from the early 1990s, frequencies previously allotted to television channels 4 and 5 have been re-allocated for FM radio, thereby harmonizing it with the Western allocation for FM radio service.
