WTZA (1010 AM) is a commercial radio station in Atlanta, Georgia, known as "Radio Punjab". It is owned by Radio Spice, LLC, and airs a South Asian format. In the daytime, WTZA has the maximum power for AM stations in the U.S., 50,000 watts. But because AM 1010 is a Canadian clear channel frequency, WTZA must reduce power at night when radio waves travel farther. During critical hours the power is 45,000 watts and at night it broadcasts at 78 watts. It uses a non-directional antenna at all times, located off Battle Forrest Drive in Decatur, near Interstate 285. WTZA is classified as a class D AM broadcast station according to the Federal Communications Commission. History WEAS The station originally signed on in 1947 with the call sign WEAS and was licensed to serve nearby Decatur, Georgia. The station was founded by Eurith Dickenson ("Dee") Rivers, Jr., son of former governor of Georgia E.D. "Ed" Rivers. The WEAS call sign stood for Emory University & Agnes Scott College, both of which are located in Decatur. WEAS's format grew into a combination of country and western music, southern gospel music and preaching. In 1963, the station changed its call sign to WGUN It had a country music format with the station adopting "the big GUN" slogan. The WEAS call sign went to the Dee Rivers station at 900 MHz in Savannah, Georgia. WTZA On January 25, 2013, the station changed its call sign to WTZA. On January 31, 2013, after a brief simulcast with W233BF "Streetz 94.5", it changed its format to urban oldies, branded as "Old School 1010". Again after a simulcast of 94.5 (legally, WSTR FM 94.1 HD3), "broadcast translator" station W257DF on 99.3 switched to simulcasting WTZA at the end of summer 2014, upon making its most recent move toward metro Atlanta. However, since W257DF was only recently authorized by the FCC, it is illegal for it to rebroadcast anything other than another FM station's analog signal. The city of license for this station is Dallas, Georgia, although it has never actually had that city within its broadcast range. It transmits at 99 watts instead of 250, to protect WRAS FM 88.5, which overlaps its 10.7 MHz intermediate frequency centered on 88.6. Originally applied-for during the 2003 window, the first location northwest of Villa Rica was approved in December 2013 at the full 250 watts. Just a few
