WFME cannot be easily moved to the east due to being shortspaced to various stations around the region, including WMAS in Enfield CT. And PST still has to contend with co-channel WDAC and adjacent channel WJLK if they want to attempt to go non-d. Scott Fybush can explain better than I can - in face, I believe he has over on the NYC page why WFME is boxed in pretty tight.
The best is that they can hope for is some reduced interference in M/S/U, and thats if WFME somehow gets shoehorned in off of 4 Times Square or Empire.
Here's what Scott Fybush said re: WFME moving -
"I dig pretty deeply into the allocations issues in this morning's NERW column over at fybush.com...Freebird is right on track with his comments, and I'd add a few more points:
-WIGX and WRKI are non-factors; under pre-1964 grandfathering, there's no protection to second-adjacent stations, which is how 93.5 and 96.7 moved into the Bronx.
-Moving to any NYC site (4TS, ESB, Freedom Tower) would decrease the interference between WFME and WPST. It is not clear to me, from a quick read of 73.213, whether a buyer of WFME could use that interference reduction to help offset an increase in interference to WMAS.
-There is a provision in 73.213 that allows a station to make a "public interest" showing to outweigh increased interference, especially if they can demonstrate that areas receiving new interference have at least five other full-time broadcast services. I don't recall this provision being successfully invoked any time recently.
-There is no aperture available at Empire (to the best of my knowledge) for a new directional FM antenna. The rent for a standalone FM antenna there could well be prohibitive. There's a reason everyone else on Empire combines into one of two master antennas.
The scenario is definitely different depending on whether Citadel or anyone else gets 94.7. Citadel has lots of options for downgrading WMAS to make a NYC 94.7 work; conversely, it can use WMAS as a convenient blocker to thwart anyone else's attempts to upgrade WFME."
