FM channel 200, 87.9 MHz, overlaps TV 6. This is used only by K200AA.; 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.
The Pan-American television frequencies are different for terrestrial and cable television systems. Terrestrial television channels are divided into two bands: the VHF band which comprises channels 2 through 13 and occupies frequencies between 54 and 216 MHz, and the UHF band, which comprises channels 14 through 36 and occupies frequencies between 470 and 608 MHz.
Very high frequency (VHF) is the ITU designation [1] [2] [3] for the range of radio frequency electromagnetic waves (radio waves) from 30 to 300 megahertz (MHz), with corresponding wavelengths of ten meters to one meter.
The radio spectrum is the part of the electromagnetic spectrum with frequencies from 3 Hz to 3,000 GHz (3 THz).Electromagnetic waves in this frequency range, called radio waves, are widely used in modern technology, particularly in telecommunication.
Under the original NTSC-M analog standards, a TV station's audio and video components are broadcast separately, with the audio transmitted as an FM signal. In 1945, TV channel 6 was assigned use of 82-88 MHz, [10] with the channel's audio located at a center frequency of 87.75 MHz. That same year the standard FM broadcasting band was reassigned ...
According to the FCC, as of March 31, 2011, there are 1022 UHF commercial television stations, 360 VHF commercial television stations, 285 UHF educational television stations and 107 VHF educational television stations, plus 439 Class A UHF television stations, 76 Class A VHF television stations, 3043 UHF television translators, 1411 VHF television translators, 1656 UHF low-power television ...
The International Telecommunication Union defines frequency allocation as being of "a given frequency band for the purpose of its use by one or more terrestrial or space radiocommunication services or the radio astronomy service under specified conditions". [2] Frequency allocation is also a special term, used in national frequency ...
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.
