I don’t know what’s so interesting about it. There have probably been hundreds, if not thousands of radio stations around the world that have used the branding “The Beat”. Probably just as common as the surname “Smith”.
KNRK’s a directional signal with some huge nulls in East Vancouver. W7PAT tells me it’s to protect KLYK. Once in a really great long while, under the right conditions, I can null out KNRK’s sideband on 94.9 and faintly hear KIOK.
Have OETA released that particular Welk episode for public TV? And if they have, did they include the stereo mix?
I have seen several black & white Welk programmes on OPB in the past, all from the 50s, but none in stereo as far as I have been aware. (Of course, my parents’ having a mono TV set at the time didn’t help matters much, either….)
