You most certainly can receive the Miami FM stations in West Palm Beach. I lived there in 1980-1981 and they came in like locals both in the car and at home using nothing more than a twin lead dipole 4 feet off the floor.
Yes, you can receive them... but the are not "listenable" in most of the county. It's been widely studied that FMs get about 80% of their AQH listening in the 70 dbu contour. That is the contour where nearly any radio will pick up a station with ease. No Miami FM has a 70 over Palm Beach County or anything except the sliver at the coast where Boca is.
95% of listening is in the 64 dbu contour, which extends into the county a few miles more... but not near WPB itself.
If you have to position an antena (most radios use the power cord today) it ain't gonna happen.
My point, though, is that no Palm Beach station covers Dace, and only 5 FMs put 64 dbu signals over all or part of Broward, while even the best Miami FMs only cover well a small porting of southern Palm Beach County, so were it to be suggested that the radio maket be extended, it would neither meet the 55/15 rule at Arbitron nor would any subscriber in either market vote for it.
