WNCC

I'm not 100% certain but I think this t-shirt is from the radio station at Northampton Community College in Bethlehem, Pennsylvania.  The artist dated their drawing to 1988 (click it bigger) and this 2014 article says the college has had a radio club for over 30 years so the math adds up.  The station currently streams online but it's unclear whether they broadcast terrestrially or via carrier current when this shirt was new.  Anybody know?

Another WNCC existed at 950 AM in Barnesboro, Pennsylvania from 1950 until 2010.  The current terrestrial WNCC has only had those call letters since 1999.
