WWJZ (640 AM) is a radio station licensed to Mount Holly, New Jersey, serving Philadelphia and the Delaware Valley. The station airs catholic–talk radio programming and is owned and operated by Relevant Radio.
The station's transmitter is located near the intersection of U.S. Route 206 and County Route 630 in Pemberton Township, New Jersey, and station offices are in Fort Washington, Pennsylvania. WWJZ operates with 50,000 watts in the daytime, the maximum permitted for AM stations by the Federal Communications Commission. Because 640 kHz is a clear-channel frequency, WWJZ must reduce power to 950 watts at night to avoid interfering with other radio stations such as KFI in Los Angeles and CBN in St. John's, Newfoundland and Labrador, Canada, the dominant Class A radio stations on 640 AM in North America.
