European Band III allocations vary from country to country, with channel widths of 7 or 8 MHz. The standard channel allocations for most of Europe are 7 MHz wide and are as follows:
The Irish (8 MHz) system is shown below.
The band came into use for radio broadcasting at the turn of the 21st century and is used for Digital Audio Broadcasting.
It is subdivided into a number of frequency blocks:
In the UK and part of Ireland, Band III was originally used for monochrome 405-line television; however, this was discontinued by the mid-1980s. Other European countries (including Ireland) continued to use Band III for analogue 625-line colour television.
Digital television in the DVB-T standard can be used in conjunction with VHF Band III and is used as such in some places. The use of sub-band 2 and sub-band 3 band for Digital Audio Broadcasting is now being widely adopted. Sub-band 1 is used for MPT-1327 trunked PMR radio, remote wireless microphones and PMSE links.
In North America, use of the band for color television broadcasts is still widespread. Favorable propagation characteristics and reasonable power limits (up to 65 kW for full-power digital television, versus 20 kW or less on VHF Band I) has meant that many US broadcasters elected to move their full-power ATSC stations from UHF frequencies to Band III VHF when all full-power NTSC analog television services in the US shut down in 2009.
