The two Marions add something special.
OK, here is one that will require someone with better resources, or a better memory than I, or both.
I should have suggested similar sounding call letters or the same station name.
These stations, and I think their call letters were something like WAIV and WAVE or similar, were co-channel, were close enough to QRM each other, and were both called "The Wave" or "Wave FM".
One was in Jacksonville, FL, and the other I think was north of Jacksonville, Maybe eastern Georgia or eastern South Carolina.
All I remember is driving through the area and being very confused, and that was in the late 60s or early to middle 70s.
Let us find out the details, because I do not know what they are or were and am curious.
