There really aren't. New wave was a subgenre of a subgenre. The songs were never really that popular when they were current. Even Elvis Costello, who was one of the leaders of the new wave, has had to reinvent himself, and only does a handful of his new wave songs in his show today.
That's what I was thinking. It's the sort of format that might work as a SiriusXM pop-up channel for a couple of weeks or even a month, maybe "curated" by Costello or Debbie Harry or some other New Wave notable as a single-artist-and-friends channel, like Jimmy Buffett's Margaritaville or Garth Brooks' channel, with the "curator" playing his own songs every fourth or fifth song. But as a full-time channel or OTA station, no way. Note that Retro is nostalgic for the sound of WFNX, which was always a cult favorite rather than a solid ratings getter in its day. It was kept afloat by the owner's alternative newspaper, The Boston Phoenix, back in the days when newspapers were cash cows.
