On August 7, 2002 I recorded a  programme of the German TV station MDR (Mitteldeutscher Rundfunk) titled �Krieg der Geheimdienste. Der Mann, der die NATO verriet � Topspion Topas�. This first episode of a series on spies was about Rainer Rupp, code name �Mosel� and later �Topas�, a West German citizen recruited by the HVA (Hauptverwaltung Aufkl�rung of the GDR) who worked his way to the NATO General Secretary and forwarded a vast amount of military secrets to the East Germans.

The interesting point of this excerpt is, in my opinion, that it confirms once more that the �4-Note� numbers station was indeed directed from the GDR to their secret agents in the West and it even suggests that this very station was also used to control �Topas�.

The TV show transcript follows:
[in German]
[Sprecher, Off:] ...sie umfassen die gesamte Planung f�r die Stationierung der Raketen. Das gelingt ihm nicht zuletzt deshalb, weil er ein hoch angesiedelter Mitarbeiter im Generalsekretariat ist; niemand sch�pft Verdacht. Die Unterlagen sind hochbrisant; nur wenige haben Zugang. Er fotografiert die Dokumente in seinem Br�sseler B�ro, bringt sie zur�ck, steckt die Filmrollen ein und nimmt sie mit nach Hause. Die HVA in Ost-Berlin teilt Rainer Rupp in Br�ssel mit, wann und wo er den Kurier treffen soll.

[Ausschnitt Interview mit MfS-Mitarbeiter:] "Wir haben ein Telegramm fertig gemacht, ein verschl�sseltes, und haben per Funk, per einseitigem Funk, die Treff-Vereinbarung, also den Tag, den Ort und die Uhrzeit best�tigt."

[Sprecher, Off:] Topas hat die Benachrichtigung erhalten und er entschl�sselt sie. Er macht sich auf den Weg ins nahe gelegene Antwerpen; dort soll er in einem Restaurant im Zentrum der Stadt den Kurier Heinz Schmidt treffen.
[Ausschnitt Interview Schmidt:] "Dann ist er auf..."

[Announcer, off:] ... they cover the complete planning for the stationing of the missiles. He succeeds not least because he is a high ranking member of the General Secretary; nobody became suspicious.
The documents are highly confidential, only few have access. He photographs the documents in his Brussels office, puts them back, tucks the film rolls in and takes them home.
The HVA in East Berlin informs Rainer Rupp in Brussels, when and where he is to meet the courier.

[simultaneously a cue on the screen: �Original MfS radio message� (!)]
[Excerpt of an interview of a MfS member:] �We prepared a telegram, an encoded one, and by radio, by one-way radio, we confirmed the appointment, that is, the day, the location and the time.�
[Announcer, off:] Topas has received the notification and deciphers it. He sets off for the nearby Antwerp; there he is to meet the courier, Heinz Schmidt, in a restaurant in the centre.
