Local Networks Alexandria/Pineville, LA

[rustolem]

Sorry if this has been asked before but a couple of months ago I switched locals from NewOrleans to the Alexandria/Pineville, LA area and ever since I have been hearing a popping? noise from the CBS channel, the CBS broadcast is done through the same station that sends out the NBC signal.
Just wanted to know if anyone else from this area is having this problem?
Thinking I may have to "move" back to New Orleans if this keeps up.

Thanks for any responses.
