Working Principle

The DIY Radio Transmitter operates based on the fundamental principles of radio frequency (RF) modulation and transmission. The core components, including the transistor, resistors, and capacitors, form an oscillator circuit. When powered on, this circuit generates an alternating current (AC) at a specific frequency, producing a radio frequency signal. The antenna attached to the circuit converts the electrical signals into electromagnetic waves, which travel through the air. A modulation process is applied, allowing the transmitter to encode audio signals or data onto the RF carrier wave. The transmitted signal can then be received by a nearby radio receiver tuned to the same frequency. The inclusion of LEDs and other visual indicators enhances understanding of how electricity flows through the circuit and provides instant feedback during assembly and operation.
