The last British VHF TV transmitters closed down on January 3, 1985. VHF band III is now used in the UK for digital audio broadcasting, and VHF band II is used for FM radio, as it is in most of the world. Unusually, the UK has an amateur radio allocation at 4 metres, 70–70.5 MHz.
A radio band is a small frequency band (a contiguous section of the range of the radio spectrum) in which channels are usually used or set aside for the same purpose. To prevent interference and allow for efficient use of the radio spectrum, similar services are allocated in bands.
Since there are generally pilot tones (subcarriers) for stereo and RDS the designator '8' is used, to indicate multiple signals. C3F, C3F N Analogue PAL, SÉCAM, or NTSC television video signals (formerly type A5C, until 1982) C7W ATSC digital television, commonly on VHF or UHF G7W DVB-T, ISDB-T, or DTMB digital television, commonly on VHF or UHF
Class R: VHF, 100 kW low-band (channels 2–6), 325 kW high-band. (channels 7-13) Class S: VHF, more than 100 kW low-band/325 kW high-band. Notes: Official definitions of these classes are difficult to locate. The values above are inferred from the Industry Canada database. There is some ambiguity about the difference between Classes C and D.
Marantz 2050L AM/FM stereo tuner (USA; 1978-1980) [1]. In electronics and radio, a tuner is a type of receiver subsystem that receives RF transmissions, such as AM or FM broadcasts, and converts the selected carrier frequency into a form suitable for further processing or output, such as to an amplifier or loudspeaker.
Several low-power television stations colloquially known as "Franken-FMs" operated primarily as radio stations on channel 6, using the 87.7 MHz audio carrier of that channel as a radio station receivable on most FM receivers configured to cover the whole of Band II, from 2009 to 2021; since then, a reduced number have received special temporary ...
TV 6 analog audio can be heard on FM 87.75 on most broadcast radio receivers as well as on a European TV tuned to channel E4A or channel IC, but at lower volume than wideband FM broadcast stations, because of the lower deviation. Channel 1 audio is the same as European Channel E2 audio and the video is the same as European Channel E2A.
