FM MONO Reception -2 By turning MODE switch to MONO position during reception of
FM stereo broadcast, this unit will be automatically ready for receiverbroadcast in monaural when the stereo indicator lamp turns off, it will operate as if the selector switch of other unit was set in FM MONO position.
AFC Circuit
AFC is not required in this unit, as the quality of the oscillator stage makes it unnecessary to use this AFC.

Hallo Michael-Otto,

vielen Dank für die Fleißarbeit! Wenn du den Katalog hast, kannst du mir vieleicht sagen, ob das damals das Spitzenmodel war, oder gab es schon 8000er oder noch höhere?

PS: warum wird mein Bild immer in eine URL umgewandelt?

Hallo lulabu,

zu dieser Zeit war er das Spitzen Modell von Kenwood.
Zu Ps, weiß ich nicht.

Gruß
