A shield has been added to the Si4732 receiver to suppress electromagnetic interference; an ESD device has been added to the antenna input to protect the chip.\n2. The Hi-Z circuit has been moved to the front of the antenna path and uses the more stable VCC_RADIO power supply to preserve signal resonance and reduce noise.\n3. The ability to use wired headphones as an FM antenna has been added (this requires use in an environment with a strong FM signal and a long headphone cable for optimal performance).\n4. The left and right audio channels have been swapped; the amplifier and speaker parameters have also been retuned to improve sound quality.\n\nController: ESP-32-S3\nOperating Modes: FM\/AM\/LSB\/USB (Note: Airband is not supported)\nReceiving Bands: HF\/SW\/MW\/VHF\nFrequency Range: LW, MW, SW (150kHz - 30MHz), VHF (64-108MHz)\nScreen: 1.9-inch, 170x320 resolution\nScreen Brightness: Adjustable from 32 to 255 levels\nCharging Port: TYPE-C (Cannot be charged with a fast charger)\nAudio Port: 3.5mm three-way stereo\nAntenna Port: SMA-KE (female)\nBattery Capacity: 800mAh\nColor: Black\nMaterial: Metal CNC\n\nPackage Contents:\n1 x Radio\n1 x Telescopic Antenna\n1 x Circular Antenna\n\nOnly the above package content, other products are not included.\nNote: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
