Satellit 700 international / professional
überarbeitet am 19.10.2010
In 1992, a new set was presented to follow the Satellit 500 as Grundig's top of the line
radio of the Satellit series.
The Grundig Satellit 700 is based on the Satellit 500 with improved features: The double conversion superhet covers shortwaves up to 30 MHz and offers AM-Sync mode. LCD display gives an alphanumeric display of station's names, 96 frequencies international shortwave broadcasters are permanently stored in a read-only memory segment, another 512 memories can be stored independently. With plug EEPROMS, so called "memory files", more then 2000 memory channels (with frequency, mode, alphanumeric tag) can be stored.
The set's dimensions of 30,4 x 17,8 x 6,6 cm and it's weight of 1,8 kg are similar to the ones of the set's predecessors Satellit 400 / 500. The Satellit 700 can be powered from 4 UM-1 / Mono cells for radio operation, an internal automatically recharged Li-accumulator keeps the microprocessor, clock and memories alive. The set can be run from NiCd accumulators, these are automatically recharged when the switch in the battery compartment is set to accumulator operation (ACCU) and the set is connected to mains power. The radio can also be powered from 9 - 12 V DC (center positive) from an external source or from the Grundig original power supply NR-90.
At the top edge of the set, You find only a world time chart next to the carrying handle and the telescopic antenna.
At the left hand of the set, You will find vertical rotary controls for bass and treble, the volume and the electronic lock function of the set, these controls are a great improvement over the slider controls suffering from contact problems found in older Grundig models.
The left half of the front panel is taken by the big speaker grill, this will
give You pleasant audio from the set's 1,5 Watt (for music max. 3 W) audio amplifier.
13 keys are used to switch the set on, to set it in AM or FM mode (FM in VHF band only),
they activate mono or stereo reception on the FM band, the wide or narrow bandwidth filter
and the synchroneous detection / USB / LSB reception. The MEMORY SCAN keys let You
run through the stored frequencies, the SEARCH key will activate a search to the
following signal with an adequate signal strength up or down the dial.
The easiest way to tune the set to a known frequency is to use the direct frequency keypad entry, e.g. type in 6 - 1 - 5 - 5 - FREQUENCY to listen the Austrian Radio on 6155 kHz. You can also use the main tuning knob at the right side of the receiver. The narrow/wide switch lets You select the narrow IF bandwidth in crowded conditions on the shortwave bands, when a nearby station is interfering. You might also try synchroneous detection to retune the receivers passband for about +/- 2,5 kHz to avoid an interfering carrier, or switch to single sideband band and select the sideband with less interference manually using the USB / LSB buttons. The automated synchroneous detector is improved very much in comparison to the one found in the Satellit 500. You can control the RF gain manually using the MGC control (manual gain control) at the right edge of the set.
Try to connect an external antenna in difficult conditions, there is a switch below the coaxial (German DIN45325 standard, a bit unusual outside Europe) connector. When using a long external antenna, You might use the attenuator which is active in the LOCAL setting of the SENS DX/LOC switch.
One of the most amazing features of the Satellit 700 is the "Radio Data System" capability on FM. The vast majority of central European FM stations does transmit the station information (station name, sometimes even other information as the title of the song played, the artist) and information about parallel frequencies on a subcarrier. This is most useful when travelling: at a new holiday location, turn on Your Satellit 700, slowly tune through the FM band and see the different station names showing up on the display of Your radio. The feature is specially useful when doing FM DXing on occasional band openings when very far stations come in for some minutes or hours during a sporadic E opening.
In summary, the microprocessor controlled Satellit 700 is a slightly bulky
portable shortwave receiver with excellent FM properties and integrated RDS decoder.
It's performance is very reliable, rejection of unwanted intermodulation products and spurious signals
is good thanks to the double conversion design, the audio is simply great.
