I saw the alert from NWS a few days ago, and was shocked that KWO35 was back on the air for regular broadcasts!
For those you don't know the story, the National Weather Service's NOAA radio transmitter in the nation's most populated city was taken off the air back in 2014, due to interference it was causing to the Coast Guard's communications system on the primary marine VHF calling channel 16 through a common antenna that they shared at Rockefeller Center. The National Weather Service shut the transmitter down to prevent further interference, and only powered it up for weather emergencies and interference testing. At one point, they were testing it at low power...but it was still causing interference.
Wow! It looks like they made a lot of changes that I did not hear about:
