The switch to digital television is less than a month away and the Federal Communications Commission is trying to help out viewers who still have questions about the transition. The FCC is hosting a number of DTV clinics in the next three-and-a-half weeks, including one in Bangor later this week.The clinics are designed to show folks how to hook up converter boxes, if they’re not receiving their signal through cable or satellite services. The clinic in Bangor is set for this Thursday at K-mart on Hogan Road. It will run from 4 in the afternoon to 8 o’clock that night. Anyone with questions about converter boxes or how to apply for government coupons for the boxes is welcome.
