List of broadcast and cable television channels and frequencies at Radio frequency spectrum allocations.Clay Irving's list of broadcast and cable television channels and their frequencies.Andy Davenport's Cable TV Channel Chart.The FCC rules suggest that the actual frequency of the fundamental oscillator in HRC comb generators "shall be 6.0003 MHz. from William Grant, Cable Television, 2nd edition, GWG Associates, Schoharie, NY, 1988, page 82 "Since the television signals are vestigial sideband modulated, if the beat products can be manipulated to fall on or near the RF carriers themselves, they are much less offensive." In effect, all signal carriers are spaced precisely 6 MHz apart, thus all beats generated are at 6 MHz increments. This does not reduce the beats produced, but positions them within the system transmission spectrum such that they are more tolerable. "By harmonically relating the carrier frequencies themselves it is. These are schemes that some cable systems use to reduce the visibility of beat products. "HRC" is harmonically related carriers.Channels 70 through 83 were re-allocated for other services but older equipment is capable of receiving on those channels. The frequency of over-the-air broadcast channels 2 through 69 is specified in FCC Rule 73.603.To calculate the frequency of any EIA-542 channel above 99: The standard specifies HRC channels as shown here except that channel 98 is 108.025 MHz and channel 99 is 114.025 MHz. The standard can be purchased from Global Engineering Documents. In 1997, the American National Standards Institute (ANSI) approved standard EIA-542, Cable Television Channel Identification Plan.More information on television channel frequencies: Cable channels operating on frequencies used in the aeronautical radiocommunications bandsġ08-118 and 328.6-335.4 MHz are required to be offset by 25 kHz from 50 kHz-spaced channels [FCC Rules Cable channels operating on frequencies used in the aeronautical radiocommunications bandsġ18-137, 225-328.6 and 335.4-400 MHz are required to be offset by 12.5 kHz from 25 kHz-spaced channels [FCC RulesĢ. The lower edge of the channel is 1.25 MHz below the visual carrier and the upper edge is 4.75 MHz above the visual carrier.ġ. For the aural carrier frequency, add 4.5 MHz to the visual carrier. The visual carrier frequency is shown in this chart. Cable TV Channel Frequencies Cable TV Channel Frequencies
