Ident used from February 1983 until December 31st, 1986. This is one of many callsign variants, although there's also a version without the station indicatives. From January 1st, 1987, until March 1987, the ID was altered to make the text swing to the top before getting back to the center, unlike here where the text just gets to the center. When you press the "Stop" button, you get an "interval" card, usually used when there was a gap in programming (mainly at around 12:00md). Worth mentioning that previously, test cards were used instead, with added music instead of the one that usually accompanied it.
