Pier is over the Atlantic. I was on the parking lot of the pier, a couple feet above the ground. The pier is very long (over a thousand feet). Roanoke was just a one time catch. I've heard 99.1 several times, but the other two (plus 92.3 WXLK that I heard earlier in the day) I had never gotten.
Daytime reception is really good of all those Savannah and Jax stations, but you can forget about it at night. None of the signals come in, except maybe WTKS 1290 with 5kw. WBMQ 630 also can come in, but they cut their night power a few years back from 1 or 5kw to 47 watts. Night reception is really a hodgepodge depending on the weather and the time of year.
Tonight, the Chicago signals were blasting in (even 670), other nights you can hear all the New York clears, and other nights the band is sort of closed up.
