Here's 2 very rare clips from WXTV when their newscast was called "Reporter 41" sometime in the mid 80s or so. No news opens, sorry.
Another one from the late 80s:
Hold on, I'm not done yet, I also found rare stuff from WNJU from their 1989 news magazine program, "Primera Plana". Contains station ID, and a promo for "Informador 47" and "Noticiero Telemundo CNN".

Here's an even older promo of Informador 47 circa 1987 via RetroJunk. (If anyone happen to know the original YT video(s) that contain it, let me know.
