Here's a note about WLNO, especially with regard to their signal over into Florida, as mentioned earlier: the station has been operating under an engineering STA for quite some time now as about 500 feet of cable is being replaced. The original STA request was to allow reducing the daytime power from 50 to 5kW, while maintaining the 5kW level at night using their licensed directional patterns.
As you'll note from this letter, however, authority was also granted to allow WLNO to operate
non-directional if needed with up to 12.5kW daytime and 1.25kW at night:
