It wasn't really announced or promoted (other than in the mornings on the previous format), but the new format is Classic His Radio (contemporary Christian from the 70s through the 90s). It just flipped today (probably at midnight last night). His Radio decided to end the talk format after the longtime station manager for the talk format, Gary Miller, retired after almost 40 years at His Radio (he'd been exclusively running their talk format for the last 12 years or so after being the midday personality at His Radio for almost the whole time beforehand).
I was surprised to hear Christmas music beginning April 1st as they said the new format would take effect on that date. I think they were waiting until after their annual fundraiser to flip to the new format, though, hence the "stunting" of Christmas music for the past two weeks. I don't understand why they haven't promoted it or announced it, unless that will begin next week now that it's officially flipped.
I also think their talk format was probably not listened to much anymore, especially after the end of the LMA with Clear Channel with 660 AM a few years ago (they stopped carrying any syndicated national talk shows when they ended the LMA). With this format change, His Radio now mirrors most of Radio Training Network's other stations (main channel, praise and worship channel, classic Christian channel, youth-oriented music channel).
EDIT: I'm not sure why it says I'm a new participant on this forum when I've been a member for 20 years (and even longer than that going back to the Radio-Info days, so probably 22-23 years or so). I guess it's because I don't most very much, but enjoy reading everyone's posts about radio on the various message boards).
