Someone Stole the Chicago Airwaves

Dan Roan's Face

Dan Roan was mid-sentence during the sports segment of WGN-TV's nine o'clock news on November 22, 1987 — a Sunday, the day before Thanksgiving. He was running through the Chicago Bears' latest developments when the picture cut out. What replaced it lasted somewhere between 17 and 25 seconds depending on which account you trust. A figure in a Max Headroom mask, swaying in front of a spinning corrugated metal panel. The audio was a wall of electronic buzz. Then the engineers at WGN switched to a backup line, the signal broke, and Roan was back.

Roan looked at the camera for a moment and said: "Well, if you're wondering what's happened, so am I." He joked that the studio computer had "taken off and went wild" and resumed his Bears report. The broadcast went on. In the control room, the phones were already ringing. Nobody knew what had happened. The answer was simple and deeply strange: someone with a more powerful transmitter had overridden WGN's signal. They had aimed it at the broadcast antenna on top of the John Hancock Center and won the competition.

Two hours and change later, at approximately 11:15 in the evening, the same thing happened again. This time on WTTW, Chicago's PBS station. This time the pirate's audio was intact. And this time the broadcast lasted ninety seconds.

The Character They Chose

Max Headroom was the most recognizable face on American television in 1987. The character originated in a 1985 British film as a satirical AI newscaster — a journalist named Edison Carter who was mortally injured while investigating corporate corruption, his consciousness digitized into a glitching, stuttering, self-aware computer construct. The character was played by actor Matt Frewer in heavy latex prosthetics and makeup, edited with choppy repetitions to simulate digital compression. When he crossed to American screens, he became the pitchman for Coca-Cola's "New Coke" campaign, appearing in nationally broadcast commercials with the tagline "Catch the wave." He got his own American talk show on Cinemax. He appeared on the cover of Newsweek.

The Max Headroom TV series, which aired on ABC, centered on a corporation that controlled all broadcast media and used Max as a propaganda tool. In the fiction, Max was capable of hijacking Network 23's signal without warning. The series was cancelled by ABC in September 1987 — roughly two months before someone wearing a mask of Max's face actually hijacked two Chicago television stations.

Whoever chose this disguise understood the joke. Max Headroom was a character who broadcast without permission, who mocked corporate media from inside it, who appeared on your screen whether you wanted him or not. The choice was a statement, even if the rest of the broadcast was barely coherent.

Ninety Seconds on WTTW

The second intrusion interrupted WTTW's broadcast of the Doctor Who serial "Horror of Fang Rock" partway through. Unlike the WGN incident, where engineers switched frequencies fast enough to kill the audio entirely, WTTW had no engineers on duty at the Sears Tower transmitter that night. The monitoring technicians at the station's broadcast center tried to intervene but couldn't reach the hardware in time. The pirate broadcast ran its full course.

What Chicago viewers saw was a figure in a Max Headroom mask and dark sunglasses, swaying against a corrugated metal background. The pirate spoke. The audio was distorted and occasionally difficult to parse, but enough came through to reconstruct the sequence. The figure called WGN sportscaster Chuck Swirsky a "frickin' liberal." It held up a Pepsi can, referencing Coca-Cola's Max Headroom "Catch the wave" commercials. It hummed the theme from Clutch Cargo -- a low-budget 1950s children's cartoon that aired in reruns on WGN Channel 9 -- and said "I still see the X." It made a scatological reference to the Chicago Tribune, which WGN's parent company owned and which branded itself "The World's Greatest Newspaper." It held up a knitted glove and said its brother had the other one, but it was dirty. It cried: "Oh no, they're coming to get me!"

Then, in the final seconds, the figure bent forward. An unseen person in a French maid costume appeared and spanked the pirate with a flyswatter. The pirate wailed. The broadcast cut out. Doctor Who resumed.

"Well, if you're wondering what's happened, so am I."

— Dan Roan, WGN-TV sports anchor, November 22, 1987

The references throughout the WTTW broadcast cluster tightly around a specific Chicago television world: WGN's sportscasters, WGN's children's programming, WGN's corporate parent. The pirate was not speaking in generalities. They were making specific, informed, insider jabs at a particular institution. Rick Klein, chief curator of the Museum of Classic Chicago Television, who has studied the footage closely for decades, has noted that the knowledge on display went well beyond what a casual viewer would possess.

How You Steal a Television Signal

In 1987, Chicago's major television stations transmitted their broadcasts using a system called a studio-to-transmitter link, or STL. The actual broadcast antennas were not in the studios. WGN-TV's studios were at 2501 West Bradley Place, on the city's North Side. Their broadcast antenna was seven miles away, on top of the John Hancock Center at 875 North Michigan Avenue, 1,127 feet above the street. WTTW's antenna was on the Sears Tower. The studios beamed their signals to these antennas via microwave transmission, and the antennas rebroadcast them to the metropolitan area.

The vulnerability is in that microwave link. FM radio exploits what engineers call the capture effect: when two signals occupy the same frequency, receivers lock onto whichever one arrives with greater power. The laws of physics are simple. A strong enough signal, aimed at the right receiver, wins. The broadcast antenna cannot tell the difference between the legitimate studio signal and a pirate signal. It relays whatever is strongest.

To pull off what happened on November 22, 1987, you needed a powerful microwave transmitter, a directional antenna, and a position with clear line of sight to the downtown towers. You needed to know the exact STL frequency WGN and WTTW were using. You needed enough technical expertise to set up and operate commercial broadcast equipment. And you needed to do all of this quietly, in a city of three million people, without being seen.

Dr. Michael Marcus, the FCC's assistant bureau chief for Field Operations who led the federal investigation, later estimated that a surplus commercial microwave transmitter capable of doing this could have been sourced for approximately $10,000. A dish antenna the size of a satellite TV receiver, positioned on the roof of a high-rise apartment or commercial building on Chicago's North or Northwest Side, could establish line of sight to the Hancock Center's receiver. The equipment was expensive but not exotic. It was available to anyone with enough technical knowledge to know what they were shopping for.

The fact that the same operator hit two different stations in one night adds a layer. WGN's STL linked to the Hancock Center. WTTW's linked to the Sears Tower, several blocks south. Either the operator repositioned their equipment between the two intrusions, or they had planned an approach that gave them angles on both towers from a single location, or there were two separate transmitter setups. The two-hour gap between the incidents is consistent with repositioning.

The FCC Investigation

The Federal Communications Commission opened its criminal investigation before the night was over. The Chicago field office and the FCC's Washington bureau both became involved, and the FBI's Technical Services Division was brought in to analyze the footage. Technicians made enhanced frame-by-frame prints from U-Matic videotape copies of the broadcast, focusing on the upper right corner of the frame for any identifying details. The corrugated metal background, analyzed at length, appeared to be dented electrical tape on cardboard with a repeating dimple pattern -- something that could be fabricated at home with basic materials and impossible to trace.

Marcus, the lead Washington investigator, obtained what records he could. He was later candid about why the investigation stalled. "Our man in Chicago," he said in subsequent interviews, "didn't want to start knocking on doors." The Chicago field office, accustomed to routine FCC enforcement work -- spectrum monitoring, licensing disputes -- was not set up for this kind of criminal investigation. Coordination between the Washington and Chicago offices broke down. Leads that Marcus believed were worth pursuing went cold.

The FCC identified the probable transmission zone: somewhere with line of sight to the Hancock Center and Sears Tower, most likely the North or Northwest Side of Chicago. This narrowed the area but did not narrow it enough. A rooftop in a neighborhood of apartment blocks, a setup that could be assembled and disassembled in under an hour, a pirate who had clearly thought through both the technical and logistical requirements -- there was nothing to find after the fact. No one reported seeing unusual equipment. No one came forward.

The FCC announced that the perpetrators faced a maximum penalty of $100,000 and up to one year in prison. The agency asked for public tips. WTTW offered a reward. Nobody called with anything useful. No arrests were made. The statute of limitations under federal law ran five years, which meant that by November 22, 1992, any criminal liability had expired. Even if the pirate were positively identified today, no charges could be filed.

What the Broadcast Left Behind

The incident prompted immediate discussion in the broadcast engineering community about the vulnerability of STL links. If a hobbyist with $10,000 of surplus equipment could override a major-market television station's microwave uplink, the implications extended well beyond Chicago. The FCC undertook a review of STL security practices. Industry engineers recommended encrypted or frequency-hopped studio-to-transmitter links to resist capture-effect attacks. The conversation accelerated a shift toward more secure transmission architectures that was already underway for other reasons.

In 2009, the analog-to-digital television transition in the United States retired the broadcast infrastructure that the Max Headroom pirate had exploited. Digital broadcast signals are not subject to the capture effect in the same way. The specific vulnerability -- the open-air analog microwave STL, susceptible to simple power competition -- no longer exists in American commercial broadcasting. What happened on November 22, 1987 cannot be replicated using the same method. In a technical sense, it belongs to a closed chapter of broadcast history.

The Internet Era and the Ongoing Mystery

For nearly two decades after 1987, the Max Headroom incident existed mainly in the memories of Chicago viewers who had been watching that Sunday night, and in the archives of a small number of collectors who had preserved VHS recordings of the original broadcasts. Rick Klein, the Museum of Classic Chicago Television curator, had obtained a copy through a collector friend and regarded it as something precious and strange. He had been thirteen years old when it happened.

In 2006, Klein uploaded the WTTW footage to YouTube. It accumulated views steadily and then, as the platform's audience grew, quickly. By 2010, the clip had been seen by millions of people who had no prior knowledge of the incident. It became a meme before the word "meme" was in wide use in its current sense -- a piece of found media so bizarre and contextually specific that it demanded explanation, and whose explanation, once given, only deepened the strangeness. Communities on Reddit, particularly r/UnresolvedMysteries, began organizing what amounted to crowdsourced investigations.

In 2013, a computer programmer named Bowie Poag posted on Reddit claiming to have indirect knowledge of two brothers -- one technically gifted, one his caretaker -- who had been part of Chicago's bulletin board system (BBS) community in the late 1980s and whom Poag believed were responsible. He said that one of the brothers had told him on the night of November 22, 1987, at a Pizza Hut gathering, to "watch Channel 11 later tonight." He had not connected the remark to the broadcast until years afterward. He tracked down what he believed was the brothers' current address and sent a certified letter. No response came. Poag eventually said he believed they wished to be left alone, and that he would respect that.

Rick Klein, who has examined more of the primary material than almost anyone outside the original investigation, has said he believes the perpetrators had inside knowledge of WGN -- knowledge that would be consistent with a former or current employee, or with someone who had worked in close proximity to the station's operations. The references in the broadcast are too specific, too targeted, too institutional to have been assembled from public sources alone. Someone knew WGN from the inside.

"The possibility of this having been an 'outside job' is basically zero."

— Rick Klein, chief curator, Museum of Classic Chicago Television

In 2010, the hacktivist collective Anonymous directly referenced the Max Headroom incident in video communications during its campaign against the Church of Scientology, adopting the image of a masked figure interrupting broadcast media as part of its iconography. The incident had become, in the fifteen years since the statute of limitations expired, a foundational text in the mythology of technical subversion.

What It Means That No One Was Caught

The Max Headroom incident has a quality that most unsolved mysteries lack: it is entirely contained. There are no victims. There is no physical evidence of harm. The legal window for prosecution has been closed for over thirty years. Whoever did this has lived with the knowledge of it for the entirety of the internet era, watching the footage go viral, watching the theorizing, watching their broadcast become a cultural artifact -- and said nothing.

That silence is its own kind of statement. The most sophisticated act of broadcast piracy in American television history -- technically demanding, theatrically precise, culturally literate, and completely anonymous -- has remained unconfessed. Dr. Marcus, the FCC investigator, said in later years that he lost little sleep over it. Nobody died. Nothing was damaged. The broadcast infrastructure was improved as a result. The perpetrator was, by most accounts, a prankster with exceptional skills and a point to make about media, corporations, and the fiction of broadcast authority.

Someone in Chicago almost certainly knows. Perhaps they have always known. The statute ran out in 1992, and they have had every reason since then to carry their secret comfortably. They are older now. The corrugated metal panel they built is long gone. The mask is somewhere -- in a box, in a closet, discarded decades ago. The transmitter was sold or disposed of or cannibalized for parts.

What remains is 107 seconds of footage: 17 seconds on WGN, 90 seconds on WTTW. A figure swaying. A flyswatter. A Pepsi can. A man saying "they're coming to get me" and then cutting out, leaving the Doctor standing in the dark on Fang Rock, and Chicago wondering what had just happened to its Sunday night.

Nobody ever found out.
