Using quartz crystal for frequency stabilization, and receiving frequency will not drift when temperature changes.
Using professional audio DSP to process and analyze audio signal, auto mute when there is no signal or week signal as big FM base noise, in order to get rid of the annoying rustle of traditional FM radio.
Advanced digital audio signal processing (DSP) and FM phase-locked loop modulation technique (PLL) ensure less sound distortion and more stable performance.
Using incremental digital 360° rotating encoder to adjust volume and frequency, which is accurate, stable, durable, and also offers comfortable hand feeling.
LCD display is more intuitive and accurate, and has very low power consumption and tiny noise interference.

Receives NOAA weather alerts to keep you informed of severe weather and natural disasters including, floods, hurricanes, tornadoes, and earthquakes.
Digital PLL Tuned AM/FM/Weather Band Radio.
Alarm, snooze and sleep functions makes this ideal for bedside use.
Adjustable, telescoping antenna for the best possible reception.
“No Worry” battery backup option (9V battery not included) – when your power goes out, there is no need to worry, the time and alarm setting will be retained.
NOAA weather alerts, digital clock, AM/FM radio, AUX input, digital PLL tuned, AC power plug.
