Radio
[edit ]Band II is primarily used worldwide for FM radio broadcasting.[1]
Broadcast television
[edit ]Usage in Russia and in other former members of OIRT
[edit ]In the former Soviet Union and other countries-members of OIRT, frequencies from 76 MHz to 100 MHz were designated for broadcast television usage.[2] Considering 8 MHz channel bandwidth used by the Russian analog television system (System D), the following television channels had been defined:
| Channel | Frequency Range |
|---|---|
| R3 | 76-84 MHz |
| R4 | 84-92 MHz |
| R5 | 92-100 MHz |
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.
Other countries
[edit ]Both Japan, System J and Australia, System B have also had analog TV channels situated within Band II.
