![[NEW] How to Make Long Range Video Transmitter - Make Your Own Television Transmitter 3W Power](http://i.ytimg.com/vi/4VrjFP3hirs/mqdefault.jpg)

Very good project.
For those who wonder, this is a AM RF modulator that works on channel 5 (Australia) or 3 (Japan) for 107.1MHz. To be used in other regions (Europe, Americas, Asia), must change the coil and for higher channels use a RF transistor) or use a TV set with CATV band. My guess is that it can work well on lower VHS band and maybe with an RF transistor on lower channels of the VHF high band. In some coutnries, it work on VHF CATV band.
The potentiometer adjust the level of the input signal.
Can be used with a video signal B&W or color but is for video only because it do not have the audio modulator.
The TV standard - PAL, SECAM or NTSC - is determined by the video signal and not the modulator.
The modulator must be tuned on the frequency of the channel wanted (the video carrier).
Can be used with any old console, VCR, DVD or any device that have composite video output. (remember Sega Nintendo, Sinclair Spectrum, MSX?)
Also can be used for any TV that can receive the old analog TV signals (have an terestrial TV tuner) which most modern TVs do not have anymore.
Well done, thanks for your valuable information
@@inventorkr1 Well, thanks. I used to do similar modules for old consoles and home computers that did not had RF output, in early 80s, when most TV sets did not had AV input, so the only way to display them on TV was trough an RF modulator. I usually used to make them for channels 2-3 because the transistor could be any type and there was no TV interference on those channels.
Thank you for the additional information, very helpful!
@@sebastian19745 Now we are talking 😊
Wow good job to you 💯💯💯💯💯
Could you please tell me a little more. What camera are you using?
Creative video, thanks :)
Bendito sea este canal 😇😇🙏🙏
Awesome music😊
Полезная штука

Bom mesmo ..

wow fcs9018 is coming back😮
Good
i ordered crt TV at amazon
Porque en bideo de transmision está parpadeando
👍👍👍
Which camera you have used in this video? And is it possible in modern Smart TVs ?
Video cannot be received on modern TVs, only old TVs
@@inventorkr1 Okay Thanks
Yes it's possible@@inventorkr1
USE TV CHANNEL SACN
Great job...now I need to know for the PCB rotary vise at 0:12 if it's 3D printed. If yes where I can get STL files
Thanks in advance
It is sold ready-made and you can find it on Amazon or Ali Express
@@inventorkr1 I tried with several way but I can't find it...can you tell me what keyword shall I use please....

@@inventorkr1 ok I got it... 👍

Is gonna work on black-white TV?
Yes, of course

Is it possible to add four wired cameras?
Do you mean a four-wire camera or do you mean four cameras?
@@inventorkr1 I have a total of five wires: green, white, black, red, yellow.
can i add to this?
FCC open up!
Perhaps you did not read what was written in the description well. In addition, this is an educational circuit whose transmission range does not exceed outside the room of the house.
@@inventorkr1 yeah, that small setup can’t transmit far without good antenna
Range Kitna metre hai
Since you are such a Drama Queen, please insert the resistors pointing to the same direction 😅
Thank you for your comment, but what is the benefit of that?
@@inventorkr1 It looks nicer and when you read or check a PCB, you don't have to twist your head as much.
If you want to get good lifespan out of your soldering iron. Do not run it hotter than it needs to be. I think 270-280 would have done the job.
This type of soldering iron requires a high temperature setting
Is the range 50-100m ?
Why is the music so damn ANNOYING ? 😡
Yes, the transmitter is 50 metres
