Compared to the previous ATS-909 model, the ATS-909X boasts a larger LCD with a brighter backlight for easier reading. With over three times the output power of the ATS-909 (1W vs. 0.3W) and a more rigid cabinet, the ATS-909X offers superior sound quality and reliability. An additional AM RF preamplifier, DSP decode IC, and a longer telescopic antenna compared to the ATS-909 enhances the short-wave reception for improved signal fidelity. A "Squelch" setting allows you to set the sensitivity rating for radio reception, rejecting residual noise and reducing scans to faulty stations. In addition, the Sangean ATS-909X offers an alarm function with 3 timers for Snooze and Sleep features. Wake up to a conventional buzzer or one of your favorite radio presets. There's even a nap timer to catch a brief nap during the day.
