Grundig Satellit 3400 Professional (1978–1983)

The Satellit 3400 Professional was the flagship of Grundig's shortwave receiver lineup. It was the heaviest and largest set the company ever built in this category. It's a desktop/portable hybrid, a substantial 52 × 32 × 14 cm and 8.9 kg of analog radio, produced from 1978 to 1983. The "Professional" suffix marked the domestic German-market version. An "International" variant was made for export, and a later brown-colored version also exists.

The receiver covers FM, long wave, medium wave, and short wave from 1.6 to 30 MHz in ten bands with bandspread, using double conversion. It runs on mains or six UM-1 batteries. It has a digital frequency display, so you get analog tuning with a digital readout. A field-strength meter adjustment for FM reception is documented in the service literature. One Russian collector described it as "one of the last fully analog" receivers of its class, and it holds "must have" status among shortwave enthusiasts.

Surviving documentation is thinner than the set's stature suggests. No original price, sensitivity figures, or formal performance measurements have surfaced in the usual directories. Service manuals do exist. A six-page manual is available through several outlets, and the chassis is referenced as model 21UZ55A. The only condition note from a collector mentions a damaged ANL switch. One owner on YouTube, having just acquired a unit, put it this way: "usual story, of course it works from the seller, but I don't know how to use it."
