Hi-Fi TV Soundtracks (pre 1978) - Why?

[KentTeffeteller]

AT&T Long Lines was a big issue, especially the further from NY or LA/Hollywood you got. Radio networks had as many issues with audio from AT&T Long Lines as TV did. Mutual Radio Network in East Tennessee did well to have 8 Khz audio on the high end. I remember being in the control room at WATO 1290 in Oak Ridge, right when Mutual News got aired from a Satellite Feed the first time, went from barely acceptable phone feed the hour before to right in the control room with you grade in one upgrade.
