We've been being told for a few years now that all one needs to prepare for the analog/digital conversion was a converter box. In my research to determine why I cannot get my local PBS (but am now getting all other local digital), I've found that one may also need a specific antenna. I need a yellow UHF multi directional antenna, according to
AntennaWeb, about another $30.
My roommate has offered to purchase the workout on dvd, so we can quit fiddling with the tv AND I'll have it for Friday, Saturday, and Sunday (when it doesn't air on PBS). She likes how active I am around the house and neighborhood when I've had my 30 minute workout in the morning.
