Portable AM FM Radio Receiver with Headphone Amplifier LSB USB Transistor Pocket Radios 1.9inch IPS Screen Si4732 DSP Radio for Indoor Outdoor

Specification:Origin: Mainland ChinaImportant Notice:1. Headphones are not included in the shipment. The headphones shown in the image are for demonstrating FM antenna functionality only. Please provide your own headphones!2. If you have selected the metal casing version, please be aware that the aluminum alloy material provides some shielding against wireless electromagnetic signals. While this enhances interference resistance, it may also weaken Wi-Fi signal strength. Please acknowledge this before purchasing.V4 Upgrade Details:1. Added shielding cover to the Si4732 receiver section to suppress electromagnetic interference; incorporated ESD protection chips at the antenna input for enhanced safety.2. Relocated the Hi-Z circuit to the front end of the antenna path and adopted a more stable VCC_RADIO power supply to preserve signal resonance and reduce noise.3. Added functionality to use wired headphones as an FM antenna (requires use in environments with strong FM signals and sufficiently long headphone cables for optimal performance).4. Left and right channels have been swapped; amplifier and speaker parameters have been recalibrated to enhance audio quality.5. Upgraded to higher-quality components: a more sturdy telescopic antenna and a better-feeling, knob cap.Brand: AMNVOLTModel (Hardware Version): V4Housing Material: -machined metal or ABS injection-molded plastic (two material options available)Main Controller: ESP-32-S3Operating Modes: FM/AM/LSB/USB (Note: Does not support aeronautical bands)Receiving Bands: HF/SW/MW/VHFFrequency Range: LW, MW, SW (150kHz - 30MHz), VHF (64-108MHz)Display: 1.9-inch, 170*320 resolutionDisplay Brightness: 32~255 levels, adjustableCharging Port: TYPE-C (cannot be charged with fast chargers)Audio Jack: 3.5mm 3-pin stereoAntenna Connector: SMA-KE (female)Ba
