Wrong station IDs are not defensible.

It's not good production values, but if it's only online it shouldn't be a legal issue.
As I recall both stations (the AM and the FM translator) were only going to be broadcasting until 7 PM each night for now. Of course, the AM powers down to flea power at sunset, which is at 6:15 through February. In March we go to 7:45 EDT after the time change.
They probably need to come up with a plan for when we move to DST and the days are longer. In June and July FCC sunset is 8:45 EDT.
