TV broadcasters are making the switch from analogue to digital transmission this Friday. If you are using “rabbit ears” or a rooftop antenna, you must take action to continue using your old TVs after June 12, 2009. If you don't have a digital ready television and haven't installed a digital converter box, your TV will stop working unless you have cable or satellite. The deaf can call TTY number 1-877-530-2634 for more information.
