Television channel frequencies

International normalization for analog TV systems

VHF

Americas (most countries), South Korea, Taiwan, Myanmar, and the Philippines

Assignments since February 25, 1946

• System M 525 lines
• System N 625 lines
• 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.
• Channel 1 audio is the same as European Channel E2 audio and the video is the same as European Channel E2A. Channel 2 video is the same as European Channel E3 video.

Japan

• The frequency spacing for each channel is 6 MHz as [|the countries above], except between channels 7 and 8.
• Channels 1 through 3 are reallocated for the expansion of the FM band.

United Kingdom, Ireland, and Hong Kong

Ireland

• 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 reception of BBC 405 line transmissions. It was moved to Channel E due to interference from distant transmitters on channel E3 and Italian channel IA 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 IA video and Channel C audio is the same as Channel E4 audio.
• There are currently no Band I Channels used in Ireland and no plans to resume using them.
• Most Irish Cable TV systems do not follow the above channel plan as their analogue carriers are usually at multiples of 8 MHz

  Western Europe; Greenland; and most countries in Asia, Africa, and Oceania

• Channels 1 and 1A were used for early experimental broadcasts and are no longer allocated.
• Channels 15 and 16 are allocated for use in the African Broadcasting Area only.
• Channel 2A was only ever used in Austria for the Sendeturm Jauerling to avoid interferences with neighboring Eastern European TV stations.
• Channel 3 in Belgium, RTBF 1 broadcast from the Liège transmitter with 100 kW until the switchover to DVB-T.
• Channel 12 was reserved by the military in some countries 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.

  France

• Channel 1 used an earlier 441-line system and was discontinued in 1956.

French overseas departments and territories and former French African colonies

Italy

• Channels A through H are indicated in many European TVs as Channels 13–20.
• Channels B, C, D, H, H1, and H2 are identical to Channels E4, E4A, E5, E10, E11, and E12, respectively.
• Channel A video carrier is the same as Channel E2 audio 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.
• Channel C audio carrier's frequency falls into the FM band in Europe, and is also identical to American A6 channel audio.

  Eastern Europe, North Korea

East Germany (former DDR)

• From 1960 onwards European standard channels were adopted.
