The only way for there to be a true NJ station would be if the station had a COL in a Central NJ area such as Southern Monmouth/Ocean county, where the sense of being in NJ, (basically not near Philly or too close to New York either, and w/ a significant population) is perhaps the strongest.
With a COL there, the station would have to have its tower somewhere there to provide a City Grade signal there, and by the nature wouldn't be able to service NYC very well. With must-carry though, of course that is not true - the station might go Spanish or religious or infomercial all the time without any local identity, but hey assuming that was ruled out, then maybe it could have worked.
By having the COL of WWOR being Secaucus, it just made it too easy for it to not be a NJ station. But, as it was VHF 9, it couldn't be anywhere south as there could be interference with Ch.10 in Philly (analog TV concern).
Wasn't Ch. 58 (WNJB) once licensed as a commercial station? Channel 58: WRTV - Asbury Park (12/14/1953-4/1/1955).
Couldn't NJ have been able to convince the FCC to make it commercial like that Pittsburgh PBS (WQEX once noncommercial and owned by WQED), and NJ could have earned an additional profit from the sale of it?
NJ would still get NCE service WNJT and WNJN (assuming everything else with the deal with WNET stayed the same) and enough area would get signal of NJTV And maybe a new commercial licensed station could be equivalent to WFMZ 69, providing local news, and maybe Me-TV on a digital subchannel
The only losers would be the cable/sat companies as they would have 1 more must-carry channel to carry.
