WNEW is showing signs of getting cold feet over an new, experimental radio format it was widely expected to unveil this spring.

The new format was supposed to be a mix of MTV and VH1-style entertainment features with music.

“Infinity may have taken a closer look at some huge expected costs and had second thoughts about spending it all on a risky new format,” says an insider.

Even though the former home of Opie & Anthony has been promising a new format as early as later this month, few new employees have been seen at the station.

In fact, The Post has learned that Steve Kingston, program director of sister-station K-Rock (92.3) has been “intimately involved” with WNEW in recent days – causing insiders to speculate that a more traditional music format is on now the drawing boards.

Gloria McDonough-Taub, a TV producer, was recently installed by Infinity’s new MTV- and VH1-heavy management as WNEW’s “executive producer/head of programming.”

She is is said to be “visibly upset” by Kingston’s presence.

Kingston and McDonough-Taub didn’t return calls and an Infinity spokesman declined comment.
