Grundig - SATELLIT-3400 Radio

Grundig Satellit 3400 radio, manufactured in Germany. From my private collection. An excellent radio with powerful sound and superb reception. A model that is becoming increasingly rare in this condition. Connoisseurs know that producing such a model today would require high technical skill and significant costs.
The receiver is in excellent condition visually! The mechanics, buttons, rotary knobs, and station memory work flawlessly. The antenna is built-in, the tuning is intact, and the VU meters and quartz clock are functioning. It needs batteries! For some reason, it only receives signals from the upper scale! I don't know what the cause is! Maybe it needs maintenance; I haven't used it in years! The battery compartment is clean!
A power cable is included in the package.
