OK...but what about WHCN-FM 105.9 transmitting from West Peak in Meriden and another 105.9 broadcaster from Newark/New York City? After that's answered, I'll go back to 97.9 FM again.
Total apples and oranges. WHCN is a directional class B with a null toward the southwest (New York.) WQXR Newark is a lower-class B1 and runs 610 watts from Empire, while most Empire signals (WSKQ included) run 6,000 watts (10 times the ERP.) In this comparison, WHCN is the dominant signal.
When you're dealing with WSKQ and WPKX, WSKQ is a full class B on Empire, and little class A WPKX has to do more protecting.
To expand on this statement.
WPKX has to protect WCTY and WSKQ due to the FCC spacing standards as dictated in rule 73.207. WPKX is 57.76kM from WCTY, which is -14.24km short of the 72kM spacing required. Likewise, WPKX is 157.55kM from WSKQ, which is -20.45km short of the required 178kM. WPKX filed for special short spacing requirements (73.215) which would allow them to operate this short, but using a directional antenna to eliminate prohibited overlap to both stations.
As Reelyreal said, WHCN/WQXR are an old allotment, and WHCN has been operating directional against WSKQ for years. WPKX is a Docket 80-90 class A drop in, that signed on in the early 90's. So they have to be treated like a new station with new interference. (Now mind you, I am REALLY simplifiying things here. There is a lot more to it, regarding interference, etc.)
4 of the 7 West Peak FMs operate using directional patterns. 90.5, 95.7, 104.1, 105.9. 92.5, 93.7 and 102.9 are all non directional.
Scott Fybush might be able to chime in some more on the age factor here on the older B's running DA.
