The 1979 - 1982 built solid state Grundig Satellit 2400 Sl stereo can be operated from the internal mains power supply, batteries or with a rechargeable Dryfit accumulator.

The portable set with it's dimensions 59 x 29 x 12 cm was one of the bulkiest worldband radios made by Grundig ever, it was even a bit wider then the Satellit 3400. Without batteries, it has a weight of 7,4 kg .

On the upper part of the front panel in the middle of the set, You find the horizontal coarse dials for long-, mediumwaves, the six shortwave band segments and FM.
Underneath, You find the switches for Radio/Phono, mono/stereo, Muting and AFC in the FM band, the LCD frequency display with a resolution of 1 kHz and the signal strength meter.
In the middle row of controls, You find the volume, bass and treble rotary knobs of the left, the concentric knobs for main and fine tuning in the middle and the rotary band switches at the right side.
In the bottom row, You find from the left the main power, the secondary speaker / tweeter, the meter light and the counter switch. Next is the electronic wide stereo control, the AM/USB/LSB switch and the RF gain control (MVC), the BFO switch is placed in the right lower corner, quite far away from the sideband switch, another strange arrangement.

The Satellit 2400 operates as a single conversion set in the LW, MW and SW1 ranges and as double conversion set in the shortwave ranges 2 - 6. This will give You optimal reception quality with superior rejection of unwanted signals only on frequencies above 3,5 MHz. So for reception of the 60 m tropical band, the set operates in double conversion and while listening to 120 m band Australian stations, You will encounter much more unwanted spurious signals and intermodulation products from strong stations in the shortwave broadcast bands.
The receiver is quite stable for the reception of broadcasting stations, it's a poor performer when switched to CW and SSB reception in the amateur bands. The receiver has a slight drift and the frequency display resolution is not sufficient to successfully tune in radioteletype stations.
The Satellit 2400 is a nice secondary shortwave receiver for pleasant listening to strong broadcasting stations and some tropical band or ham band signals, it's outperformed by modern sets in single sideband reception. The receiver is far too bulky to be carried on trips abroad, but it's a nearly unsurpassed FM stereo performer which will give You very pleasant sound from Your favourite FM station.
The set can be found on the used market in acceptable condition, sometimes one or more of the switches in the bottom row are broken. The rotary controls usually won't suffer from bad contacts, so this set is more reliable then the pushbuttons and turret tuner used for bandswitching in the Satellit 3400.
