Amplitude Modulation AM Radio Emitter Experimental AM

The emitter is a simple AM signal source for amateur electronics and radio enthusiasts. It's simple in circuit and easy to use. It uses common parts for easy to make. A volumepotentiometer with a switch can realize the modulation depth adjustment, which is the on/off function. The amplitude modulation frequency of the emitter is 600Khz-1500Khz, which can receive a maximum distance of about 5m. 3.5mm headphone jack for external audio modulation signal. This emitter is used for debugging and maintenance of the radio, radio station, SDR receiver, and other assemblies of the tool.



Features:

【Simple Circuit for Easy to Make】: This kit is simple in circuit, it uses common parts for easy to make. A volumepotentiometer with a switch can realize the modulation depth adjustment, which is the on/off function.

【Wide AM Frequency Ranges】: The amplitude modulation frequency of the emitter is 600Khz-1500Khz. This emitter is a low- emitter and can receive a maximum distance of about 5m.

【High Sound Quality】: The sound quality is close to FM broadcasting within the rated transmission distance, with a nice signal-to-noise ratio, especially since the effect of receiving through a repeater is not much different from that of direct transmission of modulated signals. The sound fidelity is higher.

【Easy to Use】: External audio modulation signal, 3.5mm headphone jack. Connect the audio signal to the headphone jack, and turn the sliding potentiometer, you will hear the ringing sound and the LED lights up. The powersupply voltage is 5-12 V, using 2 lithium batteries powersupply, available external direct current powersupply. With LED working indicator light.

【Wide Applications】: This emitter is used for debugging and maintaining the radio, radio station, SDR receiver, and other assemblies of the tool. Especially suitable for students to learn the working principle, practice production, and testing.
