Tecsun PL-398bt radio

Tecsun PL-398BT is a PLL DSP radio receiver for listening to FM, Longwave (LW), AM / Medium Wave (MW) and Shortwave (SW) frequency bands.

This device uses DSP si4734 micro-chips (from Silicon Labs in USA) to digitize the analog radio signal. In combination with the PLL (Phase-Locked Loop) circuitry, this greatly improves the radio's sensitivity, selectivity, S/N ratio and anti-interference capability.

The Bluetooth receiving feature makes it possible to use the dual speakers to play audio from Bluetooth enabled devices, like smartphones and tablets.
