A good tuner should be capable of rejecting adjacent channel interference that is up to 33 dB stronger than the weaker desired signal. WNJT is 33.1 dB stronger than WNYT; close call. What helps is that WNJT is in a different direction, so if your antenna is aimed at WNYT, that should make WNJT weaker.
