. 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.

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.
