What ever happened to WA9RTP?

[Jeffhs]

Amateur radio station WA9RTP was located in the studios of Chicago television station WFLD in the late 1960s. I just saw a YouTube video from 1967, when WFLD-TV was covering a blizzard in the city that year; amateur station WA9RTP was mentioned in the video, with the news announcer stating that WFLD-TV was venturing into a new method of reporting news--via amateur radio.

To the best of my knowledge, WFLD-TV was the only Chicago TV station to try this. Do any of you in or from the Chicago area remember this experiment? Also, I'm curious to know when WA9RTP finally went off the air. It is no longer listed in the FCC's amateur radio call sign database.

Note: I am not from the Chicago area and have never seen WFLD-TV, or any other Chicago TV station. The only way I know anything at all about WFLD-TV or WA9RTP is from doing a Google search for the television station, and from seeing an article years ago in the (now defunct) Popular Electronics magazine about the amateur station, in the magazine's "Amateur Radio" section.

Thank you.
