They are using the national CC Christmas feed, no surprise.
Is this why it sounds like they're a delayed simulcast of 99.5 WMAG? I remember hearing the same delay on 93.9 when they did Christmas music, both as Sunny 93.9 and then in 2007 after they'd become Kiss.
BTW, where is WRDU voice-tracking from? I don't recognize any of the "DJ's" that are on there now; and there is a new voice-over as well (Chris Shebel from Kiss and some female voice-over I don't recognize). Also, the only time the RDU name is used on the air is on Chris Shebel's voice-overs (the legal ID at the top of the hour and when he says "Happy holidays from 106.1 RDU"); otherwise, the station is referred to as simply "The Christmas music station."
As for the Carolina games, we'll see tonight (basketball game vs. Ohio State) what they use for the "10-second pause for station ID"...
