Both KNAU and KPUB stations are experiencing technical issues, resulting in dead air or overlapping audio. Our software vendor is attempting to resolve the issue.

Arizona Public Radio continues to integrate new audio software for both our news and classical services, resulting in some glitches.

We appreciate your patience and continued support.
