Ilegal Low Wattage Analog TV Transmitter.

  (+11, -3)(+11, -3)
(+11, -3)
  [vote for,

What I want is an illegal low output transmitter that will take SVGA output and turn it into a conventional TV signal. I want it to plug into my Video Out port and get power and user control via my USB. I want to choose the channel. I know that we are going to "lose" that bandwidth so the government can sell it to the highest bidder. I don't care. I would love to be able to run a pirate TV station and I can't find this anywhere.

       walk into a store and ask for a VGA > RF converter. Plug that into an antenna after calculating the optimum length... Voyla, instant channel 3 (or 4).
FlyingToaster, May 29 2009

       //SVGA output and turn it into a conventional TV signal// I'm sure there are plenty of videos that do this part - some of the newer ones send their output via a scart cable, but older ones output a traditional RF signal via the 'aerial' (RF) cable - then, what FlyingToaster said. I suppose, if you had some CB gear, you could transmit on that, and have other people pick up the signal through a reversed configuration. There must be some CB Radio people who've done this and written it up already.   

       Does anyone know what *they* are going to do with the analogue TV signal allocations after everyone gets switched to digital here in the UK?   

       After all the transmitters get switched off, it might be fun to have lots of little pirate tv stations filling in the gaps. There's still quite a lot of receiving equipment out there that's already tuned to the old channels - TV hammery may be the next big thing.

       And wireless TV repeaters also interfere with WiFi and Bluetooth on the 2.4GHz bands.
coprocephalous, May 29 2009

       I am not sure about over there, but I can't see any differences to over here. The license for frequency range/s is first allocated and then bought. Allocation is by a suitably empowered organisation, ownership by a transaction. Ownership of a particular range can only be taken away by a legislative procedure. I.e. Like real estate, it always belongs to the owner, and can be sold (or leased, or rented out) like any asset, excluding expropriation by state. Whether someone is using it, or not, is irrelevant ito ownership. You would be criminally "squatting" or hijacking if you broadcast on a frequency "owned" by another party.
4whom, May 29 2009

       yes. and? I did include the work illegal in the title. The intention is to break the law. I take full liability for the use of said product. Sometimes a bit of gentile resistance by citizens produces better governance. I can think of few examples of passivity producing a superior culture.
WcW, May 29 2009

       //I did include the work illegal in the title//
No you didn't, you included the "word" "ilegal".

       //gentile resistance // What about the Jews?
AbsintheWithoutLeave, May 29 2009

       Why broadcast illegally when you can upload the same content to YouTube or put it on you own website?
Bad Jim, May 29 2009

       I'm not excluding the possibility of fierce resistance, or exodus. (title spelling corrected)
WcW, May 29 2009

       I presume that the goal here is to achieve Guerilla TV, possibly marketed to crumudgeony elder-folk who won't, or can't afford the new technology, who invested in massive christmas-tree sized antennae, and won't be able to use them any more, etc.   

       Or perhaps the goal is to transmit a "TV" signal you can then record from, for Pirate TV.   

       It may actually not be illegal if the power isn't too high. Radio frequencies were allocated in just the same way as TV frequencies, yet car radio adaptors to play iPods, and similar devices broadcast on them, while still bearing markings that claim they comply with FCC regulations.
ye_river_xiv, Jun 01 2009

       I like the idea of a bit more free-for-all on the TV frequencies. I don't really care for people buying up bandwidth because quite frankly they just seem to waste it.   

       Look at the large number of digital television 'stations' which nobody would miss if they disappeared tomorrow.
vincevincevince, Jun 01 2009

       I want the digital version of this. Unfortunately, MPEG-2 video and AC-3 audio encoders, transport stream multiplexers, and 8-VSB modulators are fairly complex beasts.
csea, Jun 01 2009

       Aren't there enough rubbish TV programs in the world already, without wanting to create more of them?
DrBob, Jun 02 2009

       Definately not, [DrBob]! Without the absolute crap, how could we ever appreciate the mediocre?
4whom, Jun 02 2009

       Silly. The stuff network TV puts out is so crappy that people are surfing the internet for 5 minute Youtube videos. Surely this is a sign that anyone intelligent enough to put out a signal will be more entertaining than the legal broadcast companies.
ye_river_xiv, Jul 04 2009

WcW, Jul 04 2009

       Yes, definitely like this. It has other applications too. I don't think YouTube does the same thing, and you could broadcast something other than conventional video such as notices, Power Point presentations or use it to make a wireless folding laptop display or other device.
nineteenthly, Jul 04 2009

       Years ago I used to wonder why they didn't fit tiny video transmitters in games consoles and VCRs so you could set them up just by tuning into the channel, no wires needed. But of course the quality would probably be terrible, and tuning in would likely take more effort than plugging a wire in.
mitxela, Jul 04 2009

       no, the issue is completely a legal one. Now that the spectrum is temporarily empty I want to take good advantage of it.
WcW, Jul 04 2009

       [Mitxela], how did your anno end up after mine when mine's a reply to yours?
nineteenthly, Jul 04 2009

       how low a wattage do you want ? AFAIK you can run most spectrum portions at a few watts or something (like walkie talkies, drive-in theatre radios, etc.)
FlyingToaster, Jul 05 2009

       I don't believe there is any leeway for devices in the TV broadcast spectrum here in the states. I have never seen such a device.
WcW, Jul 05 2009

       Channel 3/4 NTSC "RF modulators" are extremely common, should be easy to combine with an SVGA > NTSC adapter [links].
csea, Jul 05 2009

       I'm no expert, but I don't think you'd have everything you need at that point. We need watts of power, not milliwatts.
WcW, Jul 05 2009

       Milliwatts and a decent antenna should work for ~100 ft or so, or use a linear amp to boost. Here's one that should work [link]. Antenna should be matched to channel frequency for best operation.
csea, Jul 05 2009

       Someone mentioned internet broadcast, but what about local digital broadcast over wifi? The technology is cheap and the guys in the white vans aren't likely to come after you.   

       I have a Daveco uhf video sender that looked like it was on the store shelf from the 1980's until the mid 2000s when I bought it. Inputs are composite plus mono, and the channel can be set anywhere between 14-17, which apparently is the overlap between ham and uhf tv signals.
Dan Fakeman, Oct 10 2010

       The UT-66 is a reliable little low power modulater/transmitter; stick the output into a linear amplifier with the right antenna and you can transmit over substantial distances. ASTEC used to make a good range of UHF modulators for composite video, too; or tear down an old analog VCR - some of them have canned modular units for RF output, just feed them +5v and 1V P-P composite video.   

8th of 7, Oct 10 2010

       They didn't. It was simply the consequence of trying to insert another full-bandwith analog TV channel into an already crowded and confused UHF spectrum.   

       It was done by a Uk Government agency - stop looking for any sort of rational pattern there, or you'll end up back on the Thorazine.
8th of 7, Oct 10 2010

       Indeed. At least when ITV digital went down the tubes, the new operating consortium had the sense to avoid 64QAM (the high bit rate of 64QAM meant the possibility of squeezing more channels into the airwaves but made the signal 'fragile').
