. Hijacking incidents have involved local TV and radio stations as well as cable and national networks. Although television, cable, and satellite broadcast signal intrusions tend to receive more media coverage, radio station intrusions are more frequent, as many simply rebroadcast a signal received from another radio station. All that is required is an FM transmitter that can overpower the same frequency as the station being rebroadcast. Other methods that have been used in North America to intrude on legal broadcasts include breaking into the transmitter area and splicing audio directly into the feed. As a

On November 26, 1977, an audio message, purporting to come from outer space and conveyed by an individual named ‘Vrillon’ of the ‘ Ashtar Galactic Command’, was broadcast during an ITN news bulletin on

. The intrusion did not entirely affect the video signal but replaced the program audio with a six-minute speech about the destiny of the human race and a disaster to affect "your world and the beings on other worlds around you". The IBA confirmed that it was the first time such a transmission had been made. In 2022, the person behind the intrusion was identified as journalist and pirate radio DJ Bob Tomalski, after journalist Tommie Trelawny, as part of investigative podcast ''The Interruption'', discovered an old comment thread in a private Facebook group for pirate radio enthusiasts, which identified Tomalski as the perpetrator.

. MacDougall was able to perform the intrusion while working a second job as a master control operator at a satellite teleport in Florida, where he worked to make ends meet due to declining income from his satellite TV equipment business. He stated that he did it because he was frustrated with HBO's service rates and that it was hurting his business selling satellite dishes (hence his second job at the teleport). The message, placed over SMPTE color bars, broadcast by MacDougall read:

Next came PBS affiliate WTTW, where the man was seen and heard uttering garbled remarks before dropping his pants, partially exposing his buttocks, and was then spanked by a woman wearing a French maid costume with a flyswatter before normal programming resumed. This second interception occurred at about 11:00 p.m. during an episode of the ''

This incident got the attention of the CBS Evening News the next day and was talked about nationwide. The HBO incident was also mentioned in the same news report.


The Playboy Channel religious message

A broadcast of the movie "Three Daughters" on the

following the Captain Midnight incident. According to investigators, it was the religious content of the transmission and the type of equipment used that drew them to CBN. The jamming signal left behind subtle technical clues that were captured on a VHS recording made at the Playboy Channel's uplink at the time of the event – like finding "fingerprints" in the video. After investigators were confident that they identified the brand of transmitter and character generator from the video, they concluded that CBN was the culprit. Haynie, of

, was on duty at his job as an uplink engineer at the time of the jamming. CBN maintained that the FCC's case was entirely circumstantial since there were no witnesses and the signal could not be traced to a point of origin. During the investigation, experts on both sides attempted to recreate the incident with CBN's equipment. According to CBN spokesman Dino McCann, they were unsuccessful. Furthermore, CBN asserted that there was not enough power for Haynie to jam Playboy's signal but during the trial, government witnesses said the CBN station was capable of interfering with satellite transmissions. After initially being deadlocked, the jury eventually sided with the prosecution and convicted Haynie on two of six counts. (Haynie was acquitted of similar charges of interfering with the American Exxxtasy channel; a recording of the event was of such poor quality that it was unusable.) Haynie received three years of probation, a $1,000 fine, and 150 hours of community service.

) over state-run television broadcasts in Toruń, including an episode of '' 07 zgłoś się''. The messages read "''Dość podwyżek can, kłamstw I represji. Solidarność Toruń''" ("Enough price increases, lies, and repressions. Solidarity Toruń") and "''Bojkot wyborów naszym obowiązkiem.''" ("It is our duty to boycott the election", referring to the Sejm elections of 1985) with the Solidarity logo. The four men were eventually discovered and were charged with "possession of an unlicensed radio transmitter and publication of materials that could cause public unrest". At their sentencing, the judge noted their prize-winning work in the Polish scientific community and gave each of them probation and a fine of the equivalent of US$100 each (or 3,000,000 old złoty, 300 PLN in today's currency).

. In the mid-1970s so many pirates were operating around the city of Arkhangelsk, especially at night, that local people were urged to telephone reports of violators to a special number. Hijackers using call signs such as "Cucumber", "Radio Millimeter", "Green Goat", "Fortune", and others, would overpower the signal on relay stations for wired radio networks to transmit their programming, or transmit into wired radio networks during gaps in regular programming. Even though the incidents appear to have been fairly common according to reports from the BBC, most were not publicly acknowledged for policy reasons. Reports in newspapers typically referred to the hijackers as "radio hooligans broadcasting drivel, rudeness, vulgarity, uncensored expressions, and trashy music". State news organizations also attempted smear campaigns against such pirate broadcasters, claiming that they had interfered with a state frequency used by
