There was a show (in color) in either the 1970's or 1980's. The episode I'm trying to find had a man (I seem to remember him working in a deli or butcher shop) whose father had died in WWII when his troop ship was sunk. Somehow the son got a radio that was broadcasting as if it was WWII. The son radios a warning to the troop ship. The next morning, he goes to the shop and his father is there! Somehow, his warning had gotten though and saved his father. The son is overjoyed. Then, outside, the morning newspaper is dropped on the corner...by someone dressed in German military uniform. The newspaper name is something like "Cleveland Beobachter". His father was saved, but Germany won WWII.
I've looked through episode guides of all the sci-fi anthology shows I could find, but no luck. I'm certain it was from an anthology show, as it certainly was not from a serial. Does anyone happen to remember what this episode and show was?
