Tecsun PL-990x radio

TECSUN PL-990x is a portable PLL DSP multiband receiver that can receive receive FM, Longwave (LW), Medium Wave (MW) and Shortwave (SW) frequency bands and is Single Sideband (SSB) capable. 

Tecsun PL-990x is equipped with an analog High-IF circuit and DSP triple conversion decoding technology. The DSP microchip digitizes the analog radio signal which, in combination with the PLL (Phase-Locked Loop) circuitry, greatly improves the radio's sensitivity, selectivity, S/N ratio and anti-interference capability. Like other Tecsun models, it comes with a variety of "hidden features". 

Tecsun has further developed the performance of the Class AB Amplifier circuit and the ultra-dynamic full range speaker, making listening to radio stations and the newly added audio playback feature (from a microSD card or Bluetooth pairing) even more enjoyable.
