Wrong obsolete everything

This article is totally wrong by obsolescence. MUST be deleted or kept renamed 'past history of television allocations' and a new one created titled 2021 U.S.A. digital television channels and frequencies and for each region to allow other regions create their own separate articles instead of one single disaster with nothing updated. The current year 2021 channels and their corresponding radiofrequencies should be listed with real references, ignoring the arbitrary virtual naming.

Wrong ATSC frequencies

The ATSC carrier frequencies listed in the US UHF tables are wrong. They should only have 0.31MHz offset from the lower edge and they show 1.31 MHz in the tables. BEWARE!! December 3, 2010 66.218.211.100 (talk) 17:11, 3 December 2010 (UTC)[reply]

Old talk

True or false: this table can be extrapolated all the way to channel 69. 66.32.244.69 01:29, 6 Sep 2004 (UTC)

I always thought all TV channels are on a number from 2 to 69. For example, the Atlanta TV template goes from 2 to 69. But this goes all the way to 83. 66.32.244.69 02:13, 6 Sep 2004 (UTC)

TV channels in North America above 69 were reallocated to the cellular telephone service (you can actually hear cell calls on old TV sets if you tune up there). These channels were never popular for broadcasting anyway. In the US I believe the FCC is trying to reallocate the VHF television channels some day...--Wtshymanski 16:30, 3 Apr 2005 (UTC)

so that's why my old 1985 Granada TV used to pick up taxi cab dispatch information on Channels 78-83 (i found Ch. 81 was the clearest for spying...muwahahaha :D ). The Legendary RaccoonFox • Talk • Stalk 20:40, 16 December 2006 (UTC)[reply]

Question: Can anyone verify the Chinese UHF channel listing? Compared to http://stjarnhimlen.se/tv/tv.html#worldwide_0 the listing in the wikipedia article is off by +2 MHz starting at channel C25.--Stevotower 22:51, 4 April 2006 (UTC)[reply]

Suggestion: Shouldn't French overseas/etc and Cote d'Ivoire be merged since they use the same system and common channels? —Preceding unsigned comment added by CXGY (talk • contribs) 20:06, 6 September 2007 (UTC)[reply]

This article needs to be updated to show where digital TV channels fit in. For example, are 9.1, 9.2, and 9.3 really in the vicinity of analog channel 9, or are they really on associated UHF frequencies somewhere? From reading the articles on digital TV, I got the impression that the latter could be the case. I haven't found a source for this information, and it is necessary in order to know what kind of antenna to put up. Palmpilot900 (talk) 03:37, 4 February 2008 (UTC)[reply]

I found some information for the U.S.A. and added it to the article on the DTV transition. Palmpilot900 (talk) 19:09, 4 February 2008 (UTC)[reply]

British VHF list

I noticed that the list of British VHF channel frequencies states that it was discontinued in 1985. Shouldn't there be a list of the new frequencies? Or was the entire VHF band discontinued altogether? --Kyle1081 (talk) 18:39, 21 January 2011 (UTC)[reply]

VHF has not been used for TV in the UK since the 1985 shutdown of the 405-line television system. Band I got reused for private radio links, Band II is used for FM radio (and has been since about 1955), Band III was originally used for PMR, I think some of it still is, but there are now several broadcast DAB radio multiplexes in operation across the country. The UK's analogue 625-line colour TV system was only ever on UHF, but that has now been shut down and the channels reused for DVB-T digital TV.

Another problem with this article is that for some reason the graphical representation of VHF channels shows a channel 14 for the U.K., which never existed. As the table elsewhere correctly shows, the old System A VHF channels ended at ch. 13. 31.185.193.87 (talk) 10:41, 23 November 2013 (UTC)[reply]

Use of "See Also"

Links that take Wikipedia visitors off the Wikipedia site need to be in their own section to make this fact clear. Wikipedia is not a search engine. The fact that links within an article are within Wikipedia's name space is implied. Links underneath a section entitled "External Links" (or similar) are the exception. (This practice seems to prevail in WP articles -- though I do not know if it is a formal WP policy. It does, however, protect WP visitors which serves WP's interests indirectly. Of course, the practice also serves WP interests directly, as it ought to).

Centre of band?

Would it be OK to include a column in most of the tables here for the Centre Of Band? When looking at spectral masks, for example, it's fairly common to refer to the frequency by the centre. And with Whitespace use of these channels coming soon, any particular carrier in these bands is not so relevant. 212.44.19.5 (talk) 15:10, 16 January 2013 (UTC)[reply]

Digital Terrestrial Television

This page doesn't make reference to the Digital Switchover in Europe (and elsewhere). The same UHF channel numbers are used but references to vision and sound sub-carrier frequencies are now irrelevant. Additionally, channels above 60 have been cleared of TV broadcasts and work is in progress to clear channels 49 and upwards for other uses too.

Interference between neighboring channels

With the old analog systems, I seem to remember channels being allocated with adjacent numbers available in the same area. Can we confirm this and add to the article something like "unlike FM radio, television stations in the same area can be assigned to adjacent channels without interference"? -- Beland (talk) 17:46, 15 June 2016 (UTC)[reply]

VHF TV channels are 12 MHz or two channels apart - VHF Lo Band: 2, 4, 6 OR 3, 5. VHF Hi Band: 7, 9, 11, 13 OR 8, 10, 12.

UHF TV channels are 36 MHz or six channels apart - 15, 21, 27, 33, 39, etc.

That might be true for the US, but in Italy and Slovenia, I've seen adjacent channels used in the same area, and in Italy, even on the same transmitter. - OBrasilo (talk) 20:40, 9 March 2021 (UTC)[reply]
