What??[edit]

"For example, China, which used jamming extensively and still does, plays an infinite loop of traditional Chinese music while it is jamming channels." Is this true? It sounds a bit too humorous to be real. What they should really play, is the startup sound of the Windows Vista OS. —Preceding unsigned comment added by 75.36.205.58 (talk) 17:45, 24 March 2008 (UTC)[reply]

Its not totally implausable. A lot of the old Eastern bloc jammers used to use (highly distorted) speech and music (sometimes relayed from their own domestic radio services or from tapes played backwards) mixed in with white noise 80.229.222.48 (talk) 12:56, 29 March 2008 (UTC)[reply]

It seems fairly well documented by radio buffs across the net, see here for some info, including a download of the music that is used.

Phantom edits/reverts ?[edit]

Has anyone else noticed intermittant problem with some recent edits not appearing in this articles edit history which in turn seems to be causing a lot of unintentional reverting ? 80.229.222.48 (talk) 19:00, 2 April 2008 (UTC)[reply]

Jamming in the UK[edit]

It seems fairly rare but sometimes England does jamming in country. I've heard it a couple of times now myself, it's quite humourous as they use the theme music from James Bond most times. I've never been able to find any decent information on it, but the times I heard it was when there were radical right wing people on the radio. Others I've spoken to about it have heard it used against nationalists of Scotland, Ireland, Wales. Anyone ever seen a good source about this? I imagine it's quite tough to get something like that published within the UK itself due to the strong censorship abilities of the government. Forkhandles (talk) 19:52, 25 June 2010 (UTC)[reply]

During the late 1960's/early 70's the were a number of clandestine stations (illegal broadcasts made for political motives) in Northern Ireland. These were routinely jammed by the (British) Army. Both nationalist and loyalist stations were affected. 92.4.235.146 (talk) 20:58, 1 October 2013 (UTC)[reply]

More information please.[edit]

Especially on how jamming is actually accomplished. Be more specific. — Preceding unsigned comment added by Komkast22 (talk • contribs) 00:43, 13 October 2011 (UTC)[reply]

USA[edit]

How about the military use of radio jamming, as practiced by say the United States of America today? Hcobb (talk) 01:14, 21 August 2012 (UTC)[reply]

Western governments are jamming satellite in Iran?![edit]

I moved the following paragraph from the article to here since it doesn't make any sense! Foreign news and political channels are jammed in Iran since they are critical of the Iranian government and the person who wrote the following paragraph claims that it is done by the western governments. Seems like a joke to me.

"In the first quarter of 2012, it was claimed that Iran's satellite transmissions were jammed by British (operating from Bahrain), American and Israeli intelligence. The Hotbird satellite hosts Iran's many international channels including the controversial PressTV[1] (which was taken off-air in the UK in early 2012).[2]"

East German "jamming"[edit]

A further method used was operating transmitters for domestic radio stations on the same or nearby frequencies. For example, for many years East Germany operated at Wiederau a transmitter on the same mediumwave frequency (575 kHz) that Mühlacker radio transmitter used with an output power of 100 kW, which made it difficult to receive the AFN Mühlacker radio transmitter in much of the East Germany.

Was this actual intentional jamming or simply a case of a station being allocated a nearby frequency because no better frequencies were available ? The medium wave band in central Europe (particularly Germany) was heavily overcrowded during the cold war. While the presence of AFN (an English language station carrying primarily entertainment programming which nonetheless enjoyed a local following) may have been a minor irritant to the East German authorities surely RIAS or Deutschlandfunk were more obvious targets (being actually targeted at the East German population) ? Incidentally Radio Luxembourg/RTL on 1440KHz had an East German station on an adjacent frequency (1431 KHz) too. 92.4.228.57 (talk) 23:15, 29 August 2013 (UTC)[reply]

Least prolific eastern-bloc jammer[edit]

Bulgaria was one of the most prolific operators of jamming transmitters in the Eastern bloc with East Germany the least

What about Yugoslavia ? 109.152.104.54 (talk) 19:07, 14 March 2018 (UTC)[reply]

While not on the same scale as other Eastern bloc states East Germany did jam RIAS (before 1978) and Radio Glasnost (in 1989) In the 1950's a short lived VOA longwave transmitter in West Germany was also jammed. The DDR authorities claimed the stations in question used unauthorised frequencies. IIRC there was little (if any) jamming from Yugoslavia. 109.144.221.170 (talk) 22:30, 10 February 2024 (UTC)[reply]

Merger proposal[edit]

(merge in Wireless signal jammer) Most content in Wireless signal jammer is duplicated from here after [1]. While this article may be more general than Wireless signal jammer, having 2 will necessarily cause much duplication. I do not see much need for a separate article, and propose Wireless signal jammer is merged here. --Chealer (talk) 02:42, 1 March 2013 (UTC)[reply]

  • Disagree: The article Radio jamming is concerned mainly with jamming of broadcast radio (and television) whereas the article Wireless signal jammer is concerned more with cellphone and wifi jamming. The two subjects merit separate articles (albeit with see also links). 2.220.223.158 (talk) 20:46, 16 April 2014 (UTC)[reply]
  • Weak Support: Does Wireless refer to the Radio Frequency spectrum or a larger part of the Electromagnetic spectrum? Either way the articles cover over lapping frequencies and technologies. One good article would potentially cover the subject. Jonpatterns (talk) 18:33, 17 April 2014 (UTC)[reply]
  • Comment - there is also a Mobile phone jammer article.Jonpatterns (talk) 10:30, 27 April 2014 (UTC)[reply]
  • Comment - To add clarity we should merge, and change the name to "Communications Jamming". Textbooks in the field typically split up jamming/antijamming between Radar and Communications. The name Communications Jamming implies Wireless Communications Jamming because jamming wired communications does not make sense. — Preceding unsigned comment added by Supremedemency (talk • contribs) 06:48, 22 September 2014 (UTC)[reply]
  • Strong support There's clearly an overarching topic that should be described here, which neither of them is currently doing justice to. To the best of my knowledge the FCC (for example) treats them as essentially the same. e.g. CONSUMER ALERT: Using or Importing Jammers is IllegalGliderMaven (talk) 21:59, 5 January 2015 (UTC)[reply]

Name change to "Communications Jamming"[edit]

I propose changing the page title to Communications Jamming, to better distinguish it from Radar Jamming (the content is all about communications jamming). — Preceding unsigned comment added by Supremedemency (talk • contribs) 07:26, 22 September 2014 (UTC)[reply]

The article is titled "RADIO jamming" not radar jamming ! Having said that radar jamming (for military purposes or to evade road traffic speed detection) is a subject in its own right. 90.220.149.152 (talk) 11:25, 22 October 2015 (UTC)[reply]

Prisons often jam radio signals[edit]

It should be noted that prisons often jam radio signals in order to prevent radio controlled devices from being used and to prevent RC devices form delivering prohibited goods and also to block radio stations that have prohibited content — Preceding unsigned comment added by 64.222.180.90 (talk) 16:50, 6 January 2021 (UTC)[reply]

Types of Jammers section goes into detail when it shouldn't[edit]

In Methods>types of Jammers it lists portable, stationary, and self made.

The details in each of these categories isn't required though, you could make a portable jammer with a longer range, a stationary jammer does not have to run off of 230v etc. 2.31.167.154 (talk) 20:48, 9 February 2023 (UTC)[reply]
