TECSUN PL-310 DSP (Digital Signal Processing)  FM stereo．MW．SW．LW multi band portable radio. This radio is using DSP 4734 Micro-chips (from Silicon Labs in USA) to digitalize the analog MW / FM / SW broadcasting signal base on the modern software technology and radio principles. It can highly improve on radio's sensitivity, selectivity, S/N ration and anti-interference. 

And the direct frequency entry, you can easy to turn into a station that you know the band frequency. Or you can use the ATS (Auto Tuning Storage) functions on FM / MW / LW & SW bands, all the available stations will be stored in the memory automatically.

The alarm functions that you can wake by buzzer or to your favorite radio station. And the temperature function can be selected as Celsius (°C) or Fahrenheit (°F).
