Anyone transmitting TV programming on the television bands would be a pirate since there is no Part 15 allowance for low power TV.
But of all the NOUOs and NOVs issued year by year we NEVER see a pirate TV station being warned.
Are there any TV pirates?

I myself have experimented with TV but not in the sense of a "pirate" broadcaster. Rather as a tinkerer I have transmitted images perhaps 50 feet for a few minutes at a time. The experimental transmissions may have lasted a few minutes at most. The method was to feed a video signal into a simple RF signal generator external modulation input. The result was a very "soft" image as the typical TV video is from 30 Hz to 4 mHz. The RF signal generator was only capable of modulating with signals perhaps to 100 kHz. That would severely impact the detail or sharpness of the image.
I have used wireless TV broadcasters or links such as the very early "Rabbit" system. Our city used a Radio Shack wireless TV link to connect a VCR to a TV at the front of an audience. These items were of commercial manufacture and carried a Part 15 sticker. That being the case it would seem the FCC approved these "broadcasters" for use under Part 15.
Although not specifically intended to be used for "broadcasting", the end result is the same.
The Rabbit system operated in the 900 mHz band. The Radio Shack system operated somewhere in the gHz bands. Perhaps that is why these Part 15 applications were allowed as these types of systems do not operate in the commercial TV bands.

Well that's interesting.
These days with TV mostly switched to digital UHF channels with the exception of a few straggling LPTV stations still doing analog, an analog TV pirate could probably go on a lower VHF channel for years without being noticed. Unless of course I'm wrong.
I have a TV Genie, a low power transmitter that was sold for awhile on the backs of match book covers and ads in TV Guide for channel 14 UHF. I am told that the FCC raided the manufacturer and confiscated his inventory.
Also, in 1971 channel 14 was closed to TV and is now land mobile.
Also, in storage down below are VHF modulators for channels 7 and 13, capable of 0-10 Watts into a cable or (illegally) an antenna.
You won't find me doing pirate stuff on TV, but the freedom to talk about it might be a right.

Several years ago one of the Tech's at our shop purchased a Ramsey TV Broadcaster.
I don't know if Ramsey sold that as a "Part 15 Device". The device looked very similar to Ramsey's other kits, a black box about 4" X 4" X 2". It had a short, telescoping antenna and inputs for video and audio.
As I recall it operated on TV channel 4 with a range of maybe 100 feet.
