Some US television stations flip the switch to all digital broadcasts today
Tuning in a digital signal can be a bit more tricky than its analog counterpart. The signal either works or it doesn’t. There isn’t much in between such as analog’s ‘snowy’ signal. AntennaWeb can help with antenna point and direction if the television is hooked up to a directional antenna. Rabbit ears: just start playing around but when you do get in the picture, it will be better than cable or satellite. There is nothing better than free, digital TV.
