Television's Most Infamous Hack Is Still a Mystery 30 Years Later (vice.com) 116
It has been 30 years since the Max Headroom hack, arguably the creepiest hack in the television history took place. Caroline Haskins, writes about the incident for Motherboard: It was a few minutes after 9 PM on Sunday, November 22, 1987. Chicago sportscaster Dan Roan was cheerily summarizing the Bears's victory that day for Channel 9 local news. Suddenly, televisions went silent, and their screens went black. At first, it seemed like an equipment malfunction. Without warning, televisions in the area blasted loud radio static. It was overlain with the screech of a power saw cutting into metal, or a jet engine malfunctioning. At center screen, a person wore a Max Headroom mask -- a character who appeared on various television shows and movies in the 1980s. He appeared to have yellow skin, yellow clothes, and yellow slicked-back hair. As purple and black lines spun behind him, Max nodded and swayed back and forth. His plastic face was stuck in laughter, and opaque sunglasses covered his eyes, which seemed to peer through the screen. The screen went black again. After a moment, Roan reappeared. "Well if you're wondering what'll happen," Roan said with a laugh, unaware of what had happened during the interruption, "so am I." Two hours later, it happened again on another channel. This time, Dr. Who had just turned to get his companion, Leela, a hot drink, when a line of static rolled across the screen, revealing the yellow man. After 30 years and an intense FCC investigation, the people behind the Headroom hack remain unknown. The correspondent has spoken to the newscasters who were interrupted and mocked that day.

Not really a hack per se (but phreak as fuck). They just overpowered the uplink to the transmitter with their own signal.

Really all he did was overpower the microwave input the broadcaster was using to the transmitter - which are relatively low power, but even then - it's not like building or buying that kind of equipment is easy and certainly would have left a paper trail (it sounds like the FBI investigated it as well). These days of course all those aux broadcast channels are encrypted.

The studio-transmitter links of the time were all analog, all NTSC, no security at all. The transmitters were all on the same tower. All one really had to do was get a hold of the STL hardware, set the channel, beam a signal from a nearby location, and roll tape.
It used to also be that you could set the brakes on a freight train with a walkie-talkie, by sending the right command to a device at the end of the train. It might even still be the case. Nobody considered that someone else could get on your frequency back then.

The local news program does not uplink to a satellite for distribution to the transmitter. It's a simple STL - studio transmitter link. Studio in middle of city needs way to get programming to the hilltop where the transmitter is. Radio. Not magic.
If you have a transmitter that sends the same signal, and your signal is stronger, well, you get the idea.

If the local anchor was interrupted in a story by hacked video, it wasn't because his video was being sent up to a satellite and the uplink or downlink was hacked. It was a simple terrestrial STL.
If it was Dr. Who, then it was a tape delay feed from Lionheart. You would not try to do such a program live because what happens if the feed fails? If the feed fails while you are taping it you have some time to find a replacement program, or you can call the source and say you need it again. If the feed fails du

This kind of attack was easy for an advanced electronics experimenter to pull off. All that needed done was to overpower the studio's signal on the studio to transmitter link with the appropriate signal and you were in. Most of the information was provided by the sign off program as the studio to transmitter link station identification occurred during this time and the frequency was provided. This was basically a terrestrial version of the HBO attacks.
Re:Easier than you think. (Score:5, Interesting)
Exactly this. The STLs (Studio->Transmitter Links) are on 900 MHz and 2.8 GHz in Chicago. The studios are in smaller buildings (not many stories) but the main TX sites are all the tall buildings (Sears/Willis, Hancock, etc.).
The links are directional beams or dishes and they are usually directly aimed at one another, but they are not that high power and can be overridden, especially if you have equipment maintenance penthouse access and can get up to the levels those things are at. Getting that access these days is much harder, post 9/11. It would probably be impossible to replicate that hack today, plus the STL's are digital and probably encrypted these days.
Every once in a while some of my old acquaintances used to get drunk and someone would bump into one of the STL dishes causing a momentary "outage". :)

I think this makes sense as the most likely explanation.
But....where would you get the equipment able to encode and transmit the signal correctly and at enough power to override the studio signal? I'd imagine your theoretical "advanced electronics experimenter" might be able to build something like this, but I'd also guess it wouldn't be a simple project and some key parts would have been expensive. I'd also guess there's probably some encoding/modulation info you'd have to know as well.

"UHF with a frequency shift"? The transmitter will "shift down again"? No. You send the video and audio signal via whatever band you were licensed to use for your STL (UHF, SHF, whatever), the received baseband video and audio is modulated onto the TV carrier, along with any other subcarrier signals.
Generating the UHF source is trivial, especially in the 80s - every VCR and home computer had a UHF modulator.

Back in the day, most studio to transmitter links were radio, unidirectional, and LOS, so not a lot of power required. Easily overridden with say... an old van with a generator in it and a transmitter aimed at the transmitter's antenna.
Now days, it is mostly done via fiber optic links, so less of a chance there, but since most TVs still accept and work with analog signals, odds are pretty good you could just blast your own signal high enough locally to do this same thing.

If your TV is tuned to a channel it knows is digital, it will not switch over to analog. It will be looking for the digital stream with the specific ID code of the channel you are tuned to. If that is disrupted for any reason, you get the black screen of "no signal".

Please tell me which magical channel you watched this USB microscope on, when the top end of the old UHF TV band was channel 83 at a measly 890 or so MHz. Well below the 1.860 GHz you claim your microscope used for USB.
