If WBAI 99.5 goes off the air

A station in Wilmington heard in New York?
You're kidding. Remember line of sight. Curvature of the Earth. There's a reason why those two stations could operate on the same frequency.
Neither of those stations is in NJ, by the way.

How will WJBR's signal improve in NJ?
I don't know about Manhattan, but when I used to live in Monmouth County, I could pull in 93.7 WSTW to just about Freehold on my car radio and I used to be able to receive it in Hazlet with a large yagi antenna aimed south. Of course, 93.5 in New Rochelle was weak to non-existant in that area, so that helped with little or no co-channel interference. IF 99.5 in New York goes off of the air, I would imagine that WJBR would at least make it up to Monmouth County, except maybe Southern Monmouth where it would experience interference with WBHX 99.7. On the other hand, there is no 99.3 to pester 99.5's signal in Central New Jersey. Further north of Monmouth County, I wouldn't imagine picking up WJBR as the previous poster mentioned, the curvature of the earth would do in its signal in North Jersey and Metro New York.

Tropospheric ducting can and does carry FM signals beyond the line-of-sight horizon, especially along a largely coastal path like the one between Wilmington and NYC. It's not at all uncommon to get VHF signals (both FM and TV) from Wilmington, Baltimore and DC in the New York area when inversion layers in the atmosphere cause ducting. It would not be at all unusual to hear WJBR or even Washington's WIHT in New York during ducting events if WBAI were to go off the air. (Which it already does when there are power issues at Empire; WBAI is the only station there without an off-site backup.)
It would improve greatly.
It would NOT reach Manhattan. It is 103 miles from WJBR's tower to the Empire State Building which means it is POSSIBLE but would require a deliberate effort consisting of a high-gain outdoor antenna mounted several hundred feet up.
However, Staten Island -which is part of NYC- may see some spotty reception in places.
The practical limit for reception (the 35dBu contour) would lie around New Brunswick. At the 35dBu line most better car radios will decode a somewhat listenable mono signal but will still suffer from fading in & out as you drive around.
I made a map showing WJBR's 54dBu contour (City-Grade) and WJBR's 35dBu contour (the limit of reception for the most sensitive car radios) that you can view at: http://www.angelfire.com/nj2/njradio/wjbr5435.jpg

That map shows only predicted groundwave signal without taking into effect propagation enhancement such as ducting. Get a good duct going, as happens almost daily in the summer along the coast, and that 35 dBu signal can easily get much, much stronger. Anyone who's ever done any FM DXing around the region has plenty of experience with this phenomenon.
99.5 would fill up fast. With pirates.
When WBAI went off the air for over night maintenance, I could receive WJBR in Northern Essex County on my Grundig G 8. Also, a few years back, when WFME went off the air, I was able to receive a faint signal of WMAS from Springfield, MA, that was 120 miles in the middle of the day. It's very possible for FM's to reach 100+ miles regularly, it's just the FM band is so cluttered, that it seems impossible

In the same area, but reversed, I was able to receive WALK 97.5 in stereo all the way to Exit 5 on the NJ Turnpike when 97.5 in Trenton/Burlington shut down to move their transmitter a few years ago.
