摘要

描述VHF Usage.svg	English: The VHF radio band, showing usage for television, FM radio, Digital Audio Broadcasting, amateur radio, marine radio and aviation by frequency and location. Legend: Television channels are represented by their frequency blocks. Each colour represents a different TV system: Grey for system A, yellow for systems B, C and F, green for systems D and E, red for system I, magenta for systems K1 and L, and cyan for system M. The yellow and red lines in each channel block represent the main audio frequency. The other radio systems used on VHF are represented as coloured bands: blue for FM radio and Marine VHF radio, aquamarine for amateur radio, and green for DAB.
