Grundig presented it's first "real" world band radio in the later very famous "Satellite" series in 1964. The Satellit 205 was a single conversion superhet providing six spread shortwave broadcast bands using a turret tuner arrangement. The export variant sold abroad carried the designation "Transistor 5000", some of the sets came with an english language dial without the European station names.
This portable receiver was the first one in the series of Grundig Satellite World Band radios that was brought to an end 1996 with the Satellit 700.
Later Grundig Satellit were sold by Grundig U.S. and have been sold elsewhere under Eton or Lextronix labels, these have not been designed by German engineers any more.

The Grundig Satellit 205 or "Transistor 5000" has been presented in 1964 as the first one in a long series of multiband shortwave receivers. It was fully solid state, could be operated on batteries and was sold in the same years as the U.S. made solid state Zenith Trans Oceanic Royal 1000 or 3000.

The portable set with the dimensions 41 x 25 x 12 cm has a weight of 7 kg, it can be powered using batteries or an optional power supply that can be installed in the cabinet.
On the right side of the front panel, You find the vertical dials for the VHF / FM band, four shortwave bands and the medium- and longwave band. At the right of the dials, You find the bushbuttons for bandswitching, at the left the two round bandspread and main tuning controls and in between the mains switch, the signal strength meter and the fine tuning control. An AFC switch is located left of the S-meter. The volume control, the separate bass and treble controls and the switch activating the tweeter speaker, can be found on the top side of the set.

This early Satellit model provides continuous tuning over the entire shortwave range with the possibility of fine tuning in the shortwave bands S1 - S4 (called K1 - K4 on sets in German language countries), and a turret tuning arrangement for six shortwave broadcast bands. You find a small horizontal dial window of the bandspread tuning at the left above the speaker grille, the set covers the 49, 41, 31, 25, 19 and 16 m shortwave broadcast bands. In the following models Satellit 208 - 1000, the bandspread dials are situated vertically.
There has been a quite rare "Satellit 205 Amateur" variant covering the 80 - 10 m amateur bands instead of the shortwave broadcast bands.

Innenleben des Satellit 205
An interior view of the Satellit 205, You will reconize the optional internal power supply TN12.

There has been the option to separately install a BFO unit within the cabinet, this will enable the set to receive CW / morse code transmissions an the amateur bands.

This single conversion set still can be used to listen to the strong signals of the major international broadcasters on the shortwave bands. The calibration of the bandspread dials is too coarse to locate a station on a known frequency successfully. Within the continous coverage shortwave ranges, the calibration ist rudimentary, so tuning in a tropical bands station is plain guesswork.
In the sixties, the Satellit 205 has been a remarkable shortwave portable, reception quality and signal rejection was quite poor due to the single conversion design - nowadays, I consider the set as a collectors item that gives You the possibility to listen to Your local AM and FM stations as well as tuning in to some international signals, but not as a convincing DXers rig.

There exist several variants: Shortwave bands on sets to be exported to non-German speaking countries carry "S5-S10" designations and the Stations names on the mediumwave bands are omitted, on German sets sold locally You find "K5-K10" designations.
