Any chance have any WCVB TV recordings that contain the test of the emergency broadcast system between early 80s to late 90s? The voiceover if I remember right was the late Frank Averuch, and during the attention signal, the screen says "Emergency Broadcast System, Official Government Information, Civil Defense Instructions", then at the final 5 seconds or so before the attention signal ends, the screen changes to a background image of a satellite dish for the closing announcements of the test? During the announcement, it announces that WCVB serves the Boston, Southeastern Mass, and the islands area. That's all I can remember from WCVB's test of the Emergency Broadcast System.

I didn't realize Keith oberman was on cvb.... Interesting.... I think Bill O'Reilly was on the channel as well... I love these retro commercials... Grew up in NH so got all the Boston stations

I Remember the “Be a Good Sport” theme being played at 7:03. I wish someone had it in the clear.

Fantastic. Do you have any of the 'NewsCenter5' broadcasts from this time period ??

Yep - there's Father / Cardinal Law...Spotlight*
