880 audio went off air ~2 min's after 1am but the carrier lasted for a long while then disappeared, then came back, repeat... Same for 660 but early on the carrier was gone.

Only heard the usual suspects, 670 WSCR and 650 WSM. Canadian French speaking stations next to 880 but nothing stood out. Didn't even hear WWL or WLS. Problem was the constant dead air carrier.

I assume if I got up at 4am I may have heard some other stations before sunrise, if the carriers were gone. It was late and I had plans for the next day so I had to pass on any serious DXing.

This was the 2nd time in 2 months that 50K locals went off air over night. Wish they'd let us know weeks before they do maintenance, if that's possible for them to give us any advance notice.
