Seems 104.7 is a very chaotic signal near JFK airport with WTC and LI battling it out, very short spaced and very frustrating, especially for the daily commute. If the LI station moved maybe a few miles east it could go non directional (or just a bit reduced to the NW) and maybe a bit greater height would put a decent signal from maybe Valley Stream out to Islip... but Hempstead is closer to NYC and signal strength there would be better near the current transmitter vs the Plainview/Bethpage area.
