Nov 09, 2007 — Yesterday you probably heard NCPR a little differently, or not at all. We're putting up a brand new antenna tower, so we had to lower the power on the old one while the ironworkers did their work. It's fascinating and a little scaryto watch. A winch lifts 20-foot tower pieces into the air and ironworkers bolt them on top. Then they climb up another 20 feet and do it again. The new tower is 320 feet tall. The conversation is pretty good, too. David Sommerstein hung around with the winch operator for today's Heard Up North.
