TECSUN H-501x can receive FM, Longwave (LW), Medium Wave (MW) and Shortwave (SW) frequency bands and is Single Sideband (SSB) capable.
This radio receiver is equipped with an analog High-IF circuit and DSP triple conversion decoding technology. It has great performance in sensitivity, selectivity and combating interference of mirror stations (image rejection). Like other Tecsun models, it comes with a variety of "hidden features".
The full-range dual speaker design, Class AB Amplifier circuit and independent treble and bass control knobs make listening to radio stations and the added audio playback features (from a microSD card or Bluetooth pairing) even more enjoyable.
