This is interesting, but I don't recall it. I am not a ham, so my ears weren't attuned to such news. WFLD started out as an independent funded by the heirs of Marshall Field plus the Sun-Times and Daily News newspapers, which put a good amount of money into facilities and nearly nothing into programming. One of their most popular local series was called "Films With a Mind of Their Own," which was hosted by Richard Christiansen, theater critic of the Chicago Tribune, and featured industrial promotional movies, which they obviously got for free. Based on that, it doesn't surprise me that they tried to get unpaid news reporting from the ham community.
Here's a TV guide listing for July 4, 1967:

By the way, the most popular "film with a mind of its own" was titled (IIRC) "A John Is a John Is a John" and was about an odor-venting toilet design.
My two favorites were ones that used little or no narration, only music: one showing the production of Oreo cookies, and one from Western Electric showing the making of telephone cable.
