How to Build a 1 Watt AM CW Transmitter Circuit

In this article, we will show you how to build a 1 watt AM CW transmitter circuit. This circuit is simple to build and can be used for a variety of applications, such as sending Morse code or transmitting audio signals. ### Materials To build this circuit, you will need the following materials: * A 9V battery * A 1000uF capacitor * A 100 ohm resistor * A 1000 ohm resistor * A 2N2222 transistor * A 10 turn potentiometer * A piece of wire * A breadboard * A soldering iron and solder ### Instructions 1. Start by assembling the circuit on a breadboard. Connect the 9V battery to the positive and negative terminals of the breadboard. 2. Connect the 1000uF capacitor between the positive and negative terminals of the battery. 3. Connect the 100 ohm resistor between the collector and emitter terminals of the transistor. 4. Connect the 1000 ohm resistor between the base and emitter terminals of the transistor. 5. Connect the 10 turn potentiometer between the base and ground of the transistor. 6. Connect the piece of wire to the antenna terminal of the transistor. ### Testing the Circuit Once the circuit is assembled, you can test it by connecting an AM radio to the antenna terminal. Turn the potentiometer clockwise to increase the output power of the transmitter. You should be able to hear the signal on the radio. ### Conclusion This 1 watt AM CW transmitter circuit is a great project for beginners. It is simple to build and can be used for a variety of applications. With a little creativity, you can use this circuit to create your own unique projects. Here are some additional tips for building this circuit: * Use a high quality soldering iron and solder. This will help to ensure that the connections are good and that the circuit works properly. * Be careful not to overheat the transistor. The transistor can be damaged if it is heated too much. * Test the circuit before using it. This will help to ensure that it is working properly and that you are not going to damage your radio.
