In the late 2000s, he was an active buyer of radio stations. Among the stations acquired by Sima Birach and his Birach Broadcasting Corp. in that era is a Class B AM serving Little Rock with 5kw during daylight hours from 1 tower and 240 watts after dark from 2 towers.
Birach acquired the station in October 2007 along with a Tulsa AM in a $1.5 million deal brokered by John Pierce & Co. Now, that AM, which today has a FM translator bringing its Spanish-language programming some FM revitalization, is in the news. Why? An unauthorized period of silence and a OPIF filing deadline miss are set to cost Birach tens of thousands of dollars in FCC fines.
