Starting as a 10-watt class D, WREK currently broadcasts a 100,000-watt ERP signal throughout the Atlanta metropolitan area, making it among the ten highest-powered college radio stations in the United States.

Certain times focus on certain themes: mornings play Just Jazz and Classics while afternoons transmit RRR (Rock, Rhythm and Roll) and nights air Atmospherics and the notorious Overnight Alternatives.

Other weekly shows include Electronic Sound System, an experimental electronic show featuring music and in-studio performances of new and established artists that run the electronic gamut; Velvet, featuring classic and contemporary R&B and soul; Live@WREK, a live music show broadcasting local and touring artists and bands; Girl Rock!, highlighting the work of women and non-binary artists worldwide; and Slow Riot, technical, abstract math rock and atmospheric, swirling post-rock.

WREK also broadcasts play-by-play coverage of Georgia Tech intercollegiate athletics, including baseball, women's basketball, and volleyball.

[4] WREK's transmitter is a Harris HT/HD+ which outputs a 16.3 kW TPO signal into a high-gain 8-bay ERI (Electronics Research Inc) antenna, resulting in an effective radiated power of 100,000 Watts in the strongest direction.

WREK first signed on the air on March 25, 1968, broadcasting at 10 Watts from a 20-foot tower atop the Van Leer Electrical Engineering building on Georgia Tech's campus.

[10] Chief Engineer and then-student Geoff Mendenhall designed and built a 425W power amplifier which, once type certified by the Federal Communications Commission (FCC) in August 1968, brought WREK to 3,400W ERP.

Visitors to WREK's Coliseum studios were often startled by its walls, which were covered by thick layers of posters, set lists, and other music memorabilia, as well as the giant electromechanical broadcast automation machines and other large racks of monitoring and control equipment.
