WBCR

J.J. Sefton: ...when I was music director at WBCR Brooklyn College Radio)...

What th...? I DJ'd and news directed at WBCR - Beloit College Radio. 88.1FM - where you sometimes come across as TV channel 6 audio! Once an experimental early station ("since 1907"), heard as far away as New Mexico, but reduced in my day to a mighty 25 watts. "With a good Northern wind, could be heard in Rockford!"
