:Zack, here are my observations about your your latest edit of the WNSR article. 
 ::1. For some reason, you removed the info about how WNSR's daytime signal must co-exist with WNBQ's, but left in the comparison of the two stations' nighttime signals. 
 ::2. The fact that WHBQ's nighttime signal aims more or less away from WNSR's is probably just a coincidence.  WHBQ has a Class B license, which lets that station receive nighttime protection as well as give it.  WNSR, however, possesses a Class D license, which prevents it from receiving any nighttime protection from any other AM station and forces WNSR to protect any and all Class B stations on 560 kHz and nearby frequencies.  That, combined with the fact that WHBQ is a few decades older than WNSR and thus more or less enjoys a "first come, first served" edge over WNSR in the FCC's eyes, is why I think it's important for the WNSR article to mention WHBQ's impact on WNSR's signal.
