Product parameters:
Output power: 100mW
Audio frequency response range: 50Hz-18KHz
Transmission frequency:
Turn off campus broadcast 87.0MHz-108.0MHz, turn on campus broadcast 76.0MHz-108.0MHz
Frequency adjustment step: 0.1MHz/time (short key press), 1.0MHz/time (long key press)
Modulation mode: standard FM frequency modulation
Channel: LINE/USB channel (stereo), MIC channel (mono)
Equivalent noise: ≥30dB (sound quality is close to CD sound quality)
Power supply voltage: DC 3.0V-5.0V
Working current: 35mA
Transmitting antenna: 75cm whip antenna
Transmission distance: The FM transmitter module is connected to a 75cm standard whip antenna, the radio uses Tecsun PL-660, and the measured coverage radius of the open area is 100 meters. (Note: The launch distance is for reference only, and it may vary slightly due to different usage environments)

Features:
1: Use advanced digital audio signal processing technology (DSP) and FM phase-locked loop modulation technology (PLL) to make the sound quality more realistic, the performance more stable, and the long-term working frequency has no deviation.
2: LCD display is more intuitive and accurate, with extremely low power consumption and minimal noise interference. To
3: Built-in 30-level digital volume adjustment, key operation can be easily completed.
4: Power off automatically memorize the volume and frequency information before power off
5: Multi-channel audio input automatic switching
6: High-precision chip quartz crystal is used to stabilize the frequency, and the emission frequency will no longer drift when the temperature and voltage change
7: Support serial port command control
