After I cancelled my Rogers cable account I was still able to receive channels 2 thru 15 or so. Yesterday, I lost all of those????
I guess you were just lucky to receive Rogers analog cable, while it lasted, after cancelling and no longer paying for it. Rogers can cut off the digital signal from the head end, but they've stopped sending out a truck to disconnect your cable at the street. So you had analog for free until that ended. If you still want to watch TV for free, get an OTA antenna.
