Broadcast engineers maintain radio stations—their job is to keep stations on the air and making money. From rewiring a station’s equipment to fixing a transmitter on a mountaintop at 3:00 a.m., these engineers make sure that we, the listeners, can count on music streaming from our favorite stations. As a teenager, Glenn Leffler never dreamed that his desire to be a musician would spark a career in broadcast engineering. Now—running a business, teaching classes at local colleges, and recording his own albums—he is grateful that his passion for guitar and gift for electronics paved the way.
