TECSUN PL-990x Portable Multiband Radio Receiver

TECSUN PL-990x is a high-performance portable PLL DSP multiband receiver capable of receiving FM, Longwave (LW), Medium Wave (MW), and Shortwave (SW) frequency bands with dedicated Single Sideband (SSB) capability.

Equipped with an analog High-IF circuit and DSP triple conversion decoding technology, the PL-990x digitizes analog signals to work in tandem with Phase-Locked Loop (PLL) circuitry. This architecture delivers vastly improved sensitivity, selectivity, S/N ratio, and robust anti-interference performance, along with Tecsun’s popular array of "hidden features".

Tecsun has enhanced the Class AB power amplifier circuit and ultra-dynamic full-range speaker system, offering rich audio fidelity whether listening to broadcast radio or utilizing the newly integrated audio player (via microSD card or Bluetooth pairing).
