12V VHF TV transmitter circuit diagram

Hi all today I'm going to give you a Tv transmitter circuit diagram..Actually  Tv transmitters are ban in some countries. So If build this build it with your own risk.Here we have used transistor BC 108.This circuit can be operated with 12V power supply.With out supplying an antenna don't supply power for the circuit.With this circuit diagram you can send signals up to 75 m to 100 m.Try this circuit and have a nice day.

Note : # Use  correct turns when you make L1

           # Build this on a PCB

Simple Fm transmitter circuit Diagram

Today I'm going to give you a FM transmitter circuit.The most impotent thing of this circuit is we can operate this circuit with 1.5V power supply.L1 should be 5 turns of 0.7mm enameled wire wound on 3mm form.Here we have used  2SC9018 transistor.Fix 12 inch antenna .with this circuit we could transmit radio signals up to 

30 m.

Note :  #  This is only for educational purpose 

           #  Build this circuit on a PCB   

1Km Fm transmitter circuit diagram

Hi every one most of you guys asked me about some circuit diagrams which are related to transmitters So today I'm going to give you a very simple but powerful circuit diagram.This circuit can transmit signals up to 1Km in an open space.This circuit powered with 12v power supply.Here we have used very popular  transistor 2n2218.When you design this circuit diagram try to fix all the parts in a small area then you can get positive results.Without fixing an antenna don't give the power to the circuit.As an antenna  fix 30cm wire.So enjoy this wonderful circuit

Note : Don't supply power with fixing an antenna

           Build this circuit on a PCB

           

Powerful FM Transmitter Circuit Diagram

Today we are going to give you very interesting circuit diagram.Normally most of electronic lovers love to make transmitter circuit diagrams.Already FREE CIRCUIT DIAGRAMS 4U has given you many transmitters.The specialty of this circuit diagram is this is some what powerful.By using this transmitter you can send signals up to 5ooM.here we have used very famous transmitter 2N2219 .This circuit is operated by 12v power supply.Specially I would like to tell you If your country doesn't allow you to build transmitters don't try this.We have publish this with the educational purpose.If you misused this circuit FREE CIRCUIT DIAGRAMS 4U doesn't take any responsibility of that.

Note:

# Build this circuit on aPCB

# Without connecting the antenna don't supply power for the circuit

# By using some what long wire as the antenna you can send signals to long distance

Simple Transmitter Circuit Diagram

Today Free Circuit Diagrams 4U is going to give you a simple Transmitter circuit.This circuit runs with NE555 IC.We can operate this circuit diagram with 9V power supply.before supplying power don't forget to fix a wire for the antenna ( about 30 inches)

Note: 
            # Build this circuit on aPCB
           # Don't supply over 9V

Single Transistor Transmitter Circuit Diagram

We all like to make transmitters.Most of guys sent emails to Free Circuit Diagrams 4U asking simple transmitter circuit diagrams .I suppose this would be the best answer for that.The special thing of this circuit is this circuit runs with one transistor.This circuit can be operated with 3V power supply.Here we have used 2N2222 transistor. you can make the coil winding 5 turns of 24AWG wire on a 1cm plastic former.You can send signals up to 5oM in open space.

Simple Tracker circuit Diagram

Most of the guys asked about tracking circuits so today I'm going to give you a tracking circuit diagram.The special thing of this circuit is you can get the signals of this circuit through a normal radio.This circuit can signals 200M to 400M.According to the environment distance can be changed.And another special thing is you can operate this tracker circuit with 3V power.Here I have used BC557 and BC 547 transistors.

 

Note:

# Build this circuit on a PCB 
# Don't supply over 3V 
# Use H antenna to receive signals

Very simple FM Transmitter Bug

Most of viewers asked about FM transmitter circuit today I'm going to give you very small and some what powerful FM transmitter.The special thing of this circuit is we can operate this circuit with 3V.Here you can use BF414 / BF324 / BF606 transistor.

TV Transmitter circuit diagram (VHF)

Most of people ask TV transmitters.So Today I'm going to give you a very useful circuit diagram.By using this circuit you can send your signals 75m to 100m.This circuit diagram is not my own circuit one of my friends gave me this.I suppose you guys also can send your own circuit diagrams for us.Then we can publish them through our website.Here They have used common transistor BC 108 If you are unable to find this transistor you can use equal transistors like Bc337 2n2222 Bc 546















Note

# To make L1 wound 6 turns of #24 enameled wire on a 10mm air former for frequency 60 - 80 MHz For 150 - 180 MHz wound 4 turns and for 180 - 200MHz wound 2 turns.

# This circuit operates with 9V power supply

# When you build this circuit you have to build this on a little space.

# The power of this circuit is 80mW

# use a pcb to build this circuit diagram.

# This is only for educational purpose.We can bear any responsibility of this If you misused this.

# This circuit transmit only video signals .If you want to send sound signals you can use an audio transmitter

Mini FM Transmitter Circuit Diagram

This is a some what powerful transmitter.Here I have used famous Transistor 2N2222.This circuit operates with 3V power supply.To make L1 wind 5 turns of 24AWG wire on a 1cm plastic former.
