Actually, religious programs are a separate category... or were back when we had to show exactly how we served the public with Public Affairs, Religion, and Other (things like educational shows) as well as PSAs and news.Which probably counted towards the station's public affairs commitment. (e.g., "Eternal Light", or "Lamp Unto My Feet".) So not quite the same.
"The most well-known old Jewish radio station in New York was WEVD, which operated from 1927 to 2003 and became a popular platform for Yiddish and other ethnic programming. Founded by the Socialist Party and later taken over by the Yiddish newspaper The Forward (Forverts), it was known for its ethnic brokered programming, with the tagline "the station that speaks your language"As for whether any Jewish-affiliated applicant or group ever has applied for a station license, that I can't talk to. However I agree with you, if the government denied such an application based on the group being Jewish, or the proposed programming tilting that way, I'd think that applicant would have quite the 1A case.
There is apparently an LPFM operated by a Jewish group, too. Just do a "Jewish Radio Stations New York City" for more.
