The following tables show the frequencies assigned to broadcast television channels in various regions of the world, along with the ITU letter designator for the system used. The frequencies shown are for the analogue video and audio carriers. The channel itself occupies several megahertz of bandwidth. For example, North American channel 1 occupies the spectrum from 44 to 50 MHz. See Broadcast television systems for a table of signal characteristics, including bandwidth, by ITU letter designator.
Channel 1 was withdrawn on June 14, 1948, and allocated to fixed and mobile services. In some countries using the standard, channels 5 and 6 are allocated to non-broadcast services. An international agreement provides for a unified television bandplan, with 6-MHz channels throughout ITU Region II for both VHF and UHF bands, though not all territories observe this bandplan, such as French territories, the Falkland Islands, and Greenland.[citation needed]
During World War II, the frequencies originally assigned as channels 13 to 18 were appropriated by the U.S. military, which still uses them to this day. It was also decided to move the allocation for FM radio from the 42-50 MHz band to a larger 88-106 MHz band (later extended to the current 88-108 MHz FM band). This required a reassignment of the VHF channels to the plan currently in use.[1]
North America, South America, Caribbean, South Korea, Taiwan, Burma (Myanmar) the Philippines – assignments since February 25, 1946[edit]
FM channel 200, 87.9 MHz, overlaps TV 6. This is used only by KSFH and K200AA. Channel 6A is only used in South Korea and the Philippines.
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 4A or channel C, but at lower volume than wideband FM broadcast stations, because of the lower deviation.
Channel 1 audio is the same as European Channel 2 audio and the video is the same as European Channel 2A. Channel 2 video is the same as European Channel 3 video.
Channel A was never used terrestrially. The only System I Band I transmitter on Channel B was RTÉ One from the Maghera, Co. Clare transmitter during 1963–1999. Channel A was initially intended for use at Maghera but Channel B was used instead because of the risk of interference to (overspill) reception of BBC405 line transmissions.[2] It was moved to Channel E due to interference from distant transmitters on channel 3 and channel A via certain atmospheric conditions and other reasons. Channel C was used by a relay transmitter in Glanmire, Co. Cork.
Channel B video is the same as Italian Channel A video and Channel C audio is the same as Channel 4 audio).
There are currently no Band I Channels used in Ireland (except on cable TV, and these have mostly been phased out for DOCSIS use) and no plans to resume using them.
Most Irish Cable TV systems do not follow the above channel plan as their analogue (video) carriers are usually at multiples of 8 MHz (i.e. 176, 184, 192 MHz etc. in Band III)

Channels 1 and 1A were used for early experimental broadcasts and are no longer allocated.[3]
Channels 15 and 16 are allocated for use in the African Broadcasting Area only.[4]
Channel 2A was only ever used in Austria for the Sendeturm Jauerling to avoid interferences with neighboring Eastern European TV stations.
Channel 12 was reserved by the military in some countries (like Germany (West Germany only)) so only relay transmitters operated on this frequency.
Channel 4A audio carrier's frequency is very close to US Channel 6 audio carrier and overlaps the FM band in Europe
Channels A through H are indicated in many European TVs as Channels 13–20.
Channels B through H2 are identical to Channel E4 and up.
Channel A video carrier is the same as Channel E2 video carrier and thus it used to be common that the audio from a distant TV station on channel E2 received via Sporadic E interferes with Channel A video and vice versa.
In its very early days DFF made some test transmissions using the D/K standard (6.5 MHz audio) before reverting (around 1957) to System B/G (5.5 MHz audio) but using some unique frequencies.[6]
Channels 0, 1, 2, 3, 4, 5 and 5A are no longer used since the transition to digital television.
With the introduction of digital TV in 2001, the last two channels were moved up by 1 MHz (some existing services affected - one example is AMV11 in the Upper Murray region of Victoria, Australia and VTV-11 in Western Victoria, due to the introduction of digital television at the time in regional Victoria) to allow a full 7 MHz for a new channel 9A and channel 12 was added following the new channel 11.
Americas (most countries), South Korea, Taiwan , Burma (Myanmar) and the Philippines[edit]
For frequencies used in the Americas (most countries), South Korea, Taiwan and the Philippines, refer to Pan-American television frequencies.
Notes
The frequencies used by UHF channels 70 through 83 were reallocated to the Land Mobile Radio System (Public Safety and Trunked Radio) and mobile phones in a CCIR worldwide convention in 1982, and thus were never used for digital TV but are listed here for theoretical use.
In certain metropolitan areas of the United States, Channels 14 through 20 have been allocated to Land Mobile Radio (LMR) use.[8]
Channels 52 through 69 in the United States have been reallocated now that conversion to digital TV was completed on June 12, 2009. Channels 70 through 83 in the United States and Canada were re-allocated to AMPS cellular phone use in 1983.
Not all countries listed use ATSC, which has a single VSBcarrier wave. Other countries use COFDM modulation for DVB-T (Taiwan, Colombia) or ISDB-Tb (Philippines and Latin America), which has dozens of carriers within the channel.
ISDB-Tb frequency DTV channel 14 uses 473.142857 MHz, but on ATSC 3.0, DVB-T/DVB-T2, and DTMB, uses 473 MHz. Slightly same frequency, but without .142857 MHZ.
Due to the FCC repack in the United States, all TV stations that had been broadcasting from channels 38 to 51 were required to be moved on or below channel 36 by July 3, 2020.[11] These frequencies would later be used by U.S. mobile carriers like T-Mobile on Band 71.[12]

Frequency spacing for each channel in Japan is the same as in the countries listed above, but the channel numbers are 1 lower than in those countries; for example, channel 13 in Japan is on the same frequency as channel 14 in North and South America (most countries), South Korea, Taiwan, and the Philippines.
