WDAZ, NBC Grand Forks commercials [December, 1982]

I'm not 100% sure on the date. The episodes these commercials are from are:
Gimme a Break! - "A Man in Nell's Room" - Aired Dec.3, 1982
Love, Sidney - "Jan (Part 1)" - Aired Nov.27, 1982

Episode of SNL referenced airing later in the evening:
SNL Season - "Chevy Chase & Queen" - Sep.25, 1982

It also referencing upcoming episodes:
St. Elsewhere - "Legionnaires (1)" - Aired Dec.7, 1982
Little House on the Prairie - "Love" - Aired Nov.29, 1982

I think it was sometime in December, airing reruns since none of the promos mentioned "all new".
