Feature: 1. Simple Circuit Design: The medium wave transmitter is constructed using commonly used transistors and resistors, capacitors, and inductors, without the need for sound transfer equipment, making it easy to assemble. 2. Excellent Sound: The transmitter produces sound quality comparable to FM broadcasting within the designated transmission range, with a great signal to noise ratio. When connected to a receiver with a straight amplifier, the sound quality is nearly identical to directly playing the modulated signal. 3. No External Antennae Required: With no need for an external antennae (typically required for MW transmissions spanning tens of meters), the transmitter relies solely on the magnetic field leakage from the ferrite rod, resulting in easy setup and a close transmission range. 4. Versatile Interface: The AM radio transmitter features various ports including a waveform testing terminal, sound jack, and external power socket, making it user friendly and allowing for additional functionality. 5. Educational Value: Ideal for students to learn about circuit principles, practice building and testing, the transmitter utilizes discrete components and includes a dual gang variable capacitor for increased capacitance. Specification: Item Type: Medium Wave Transmitter Material: PCB Frequency Range: 525 to 1605kHz Power Supply Voltage: 6V Transmission Distance: About 1 meter for superheterodyne MW radios, about 0.5 meter for direct put and ore radios.
