ESP138D H-RADIO SI4732 Full Band FM AM SSB AIR Band Receiver + TEF6686 FM2256
Product Features:
1. **Dual-System Reception:** The ESP138D is a hardware-level dual-architecture radio, employing both the TEF6686 system (open-source algorithm) and the -SI4732 system (full-band coverage) operating independently. Switching between systems is as simple as clicking the power button while the radio is powered on. Note: Theoretically, both modes support firmware flashing, but it is recommended to use the factory default firmware; otherwise, malfunctions may occur.
2. **Dual Bluetooth Mode Support:** Users can connect their mobile phones to the radio via Bluetooth, using the radio as a Bluetooth speaker. Alternatively, radio broadcasts or audio received on the radio can be transmitted via Bluetooth to Bluetooth headphones or speakers.
Frequency:
TEF6686 Mode:
Coverage FM (65-108MHz) / LW (144-513kHz) / MW (520-1720kHz) / SW (1700-27000kHz), does not support AIR Band and SSB.
