Another example that I just remember, KLZ right here in Denver. That has been in continuous use for a terrestrial station since I think about 1922 (it's Denver first commercial station), but previously assigned to a ship that sunk in 1920 called the HMS Speedwell. What's really interesting is that the name Speedwell was originally the name of the Mayflower's ill-fated sister ship as well (it began taking on water twice and turned back, never making it to the New World).
