The station also broadcasts over the air on micropower levels throughout Saxonburg on AM 1620 and FM 100.3 under FCC Part 15 rules.

In 1946, Fred Seitz, head of the physics department at Carnegie Tech, recruited Ed Creutz, Jack Fox, Roger Sutton and Bert Corben to the university to develop an important nuclear physics research program.

By June 6, 1946, they had built a leading-edge, 450 MeV proton synchrocyclotron at the Nuclear Research Center near Saxonburg, just south of the city limits.
