About the station

Seventeen years, one transmitter, thousands of voices.

Copperline began in a converted dentist's office with a second-hand transmitter and a sign-up sheet at the farmers market. Today the station occupies a 4,000-square-foot studio and trains two dozen new volunteers every year.
