I'm looking for Wrightsville Beach Scanner frequencies also. I have tried the P25 and the old 453 frequencies and do not seem to receive any transmissions.
I was down there recently and noticed something that was common among all the officers I saw all of them in marked vehicles and in uniform. The use of bluetooth / cellphones. I saw numerous citations written up and when the cop approached the vehicle, He never left from his spot beside the driver's door and appeared to be using his cellphone to communicate back to dispatch, wrote his ticket, and went on his way.
It appears that the banana republic called Wrightsville Beach is going more and more to a cellphone system in their attempt to be more and more secretive.
