Have heard on several occasions on the Center Point Channel (Ch1) the call "STAR 2". It is a helicopter unit that is based at the Bessemer airport. The times I've heard it are at night between about 9:00 and 10:00 P.M. Suspect there is a "STAR 1" but don't know for sure or what Channel the are usually on. If anyone knows would like the information. The UID for "STAR 2" is i42161.
