WESU 88.1 FM station general manager Ben Michael stands by the station’s 30-year-old transmitter housed in the penthouse of Exley Science Center. The instrument was recalibrated to transmit 6,000 watts of effective radiated power (ERP) through a new antenna, allowing the station to broadcast into southern Massachusetts. For the past three decades, the station only produced 1,500 watts of ERP. (Photo by Olivia Drake)
