Special Features

  • Complete DIY Transmitter Kit for Learning & Experiment: This radio medium wave transmitter kit includes all necessary components for building your own AM transmitter. Perfect for school science experiments, electronics education, and amateur radio enthusiasts. Understand the principles of sound modulation and high-frequency signal generation through hands-on assembly.
  • Adjustable Frequency 530‑1600KHZ with Stable Oscillation: The built-in common base modulation transformer oscillation circuit generates stable high-frequency equal amplitude signals. Adjust the CV to set your desired frequency across the entire medium wave band (530‑1600KHZ). Includes positive feedback network and high-frequency bypass capacitors for reliable performance.
  • Sound Amplification & High-Frequency Modulation: Features IC1 sound amplifier chip with volume potentiometer (SW1) for audio input control. The high-frequency modulation circuit (Q2) further amplifies signals for clear transmission. Adjust SW2 and SW3 to fine-tune sound quality and voltage for optimal AM modulation.
  • Low-Pass Filter & Antenna Matching: The L2/L3/C26/C27 low-pass network filters out high harmonics, ensuring the output waveform is close to sinusoidal for clean transmission. Designed to match a 2-5 meter antenna (self-provided) for effective range of 5-10 meters with adjustable 20‑500mW power output.
  • Complete Kit with Instructional Manual: Package includes PCB board, all electronic components, screw package, sound cord, and detailed instruction manual. Requires 9V2A DC power supply (5.5mm interface, center positive) and a simple wire antenna (1.5-2.5mm² household wire, 2-5 meters, self-provided). Ideal for students learning wireless signal generation and AM sound modulation.
