TECSUN PL-520 is a portable PLL DSP multiband receiver that can receive FM, Longwave (LW), Medium Wave (MW) and Shortwave (SW) frequency bands and is Single Sideband (SSB) capable.

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.

The PL-520 receiver has Tecsun's new ETM+ feature, which gives the possibility of setting up time-specific memories for long wave (LW), medium wave (AM) and shortwave (SW). Its compact size is ideal for travelling. Let the radio wake you up in the morning by setting the alarm, or set the sleep timer to auto turn-off the device while listening before going to sleep. Charge the battery by connecting the radio to a 5V USB charger, one similar to those used for most smartphones and tablets.
