KNAU Arizona Public Radio continues to integrate new audio software into both our news and classical services, resulting in some glitches. Thank you for your support and patience through this upgrade.

KNAU 88.7 is restored to full power. APS cut power to our system atop Mormon Mountain to service another radio station's electricity meter and restored it early Monday morning.
