On the other hand, we were using half-mil tape at slow speed at CJRT in the
late 60s when this was the only way to record long programs to run on the
automated system. I once recorded the entire 4-hour evening jazz program with
the tape flipped, noticed it after I'd finished recording, said a few choice
words and then checked the playback, and apart from a small loss in highs (this
was mono FM and we probably had 10 listeners in those days) it didn't sound bad
enough to re-do it.
