====== Grundig Satellit 205 Amateur ====== Manufactured by [[Grundig]], Fürth. The German radio manufacturer [[Grundig]] presented its first real world band receiver in 1964. The Satellit 205, a portable single conversion receiver, was the first set in Grundig's successful series of world band receivers, which came to an end in 1996 with the Satellit 700. The receiver was produced in a version with the shortwave broadcast bands and a less common one with the spread amateur radio bands, the **Satellit 205 Amateur**. ==== Variants ==== |**[[Satellit 205]]**|Basic model with spread shortwave broadcast bands|Transistor AC151r in the AF preamplifier|14-3080-1141/62| |**[[Transistor 5000]]**|Export model for the non-European market, shortwave bands marked S1-S10 instead of K1-K10, station names missing on medium wave|Transistor AC151r in LF preamplifier|14-3080-9141/62| |**[[Satellit 205 Amateur]]**|identical model with spread amateur radio bands instead of shortwave broadcast bands|Transistor AC151r in the HF preamplifier| | |**Satellit 205a**|Successor model from 1967, two rear panel screws and two screws on both sides of the window of the drum tuner|Transistor BC108A or BSY76b in the LF preamplifier|14-3080-1341/62| |**Transistor 5000a**|Successor model from 1967, two back panel screws and two screws on both sides of the window of the drum tuner|Transistor BC108A or BSY76b in the NF preamplifier|14-3080-9241/62| {{:images:grundig-satellit205-amateur.jpg?600|Grundig Satellit 205 Amateur}} ===== Technical data ===== * [[Principle]]: [[single conversion superhet]], [[IF]] 460 kHz / FM 10.7 MHz * [[Operation modes]]: [[A1]] with [[BFO]] (optional accessory), [[A3|AM (A3)]], [[F3|FM (F3)]] * [[Frequency range]]: FM, LW, MW, 4 x general coverage SW, additional spread 160 / 80 / 40 / 20 / 15 / 10 m ham bands * [[Frequency dial]]: analogue dial * [[Frequency memory]]: none * [[Signal strength indicator]]: [[S-Meter]] * [[Signal processing]] * [[Features]] * [[Sensitivity]]: [[A3|AM (A3)]] approx. 2 μV / [[Selectivity]]: kHz (-6/-60 dB) ==== Power supply ==== * [[Batteries]]: 6 x 1.5 V ([[UM-2]]) ==== Dimensions ==== * 410 x 250 x 120 mm, weight 7 kg ==== Accessories ==== {{ :images:grundig-satellit205-power-supply.jpg?300|Satellite 205: power supply}} * optional built-in mains adapter **TN12** * optional built-in BFO for single sideband reception ---- {{:images:grundig-satellit205-amateur-front.jpg?600|Grundig Satellite 205 Amateur}} ===== Operation ===== As one of the earliest portable shortwave receivers, the Grundig Satellit 205 was introduced in 1964 as the forefather of a large family of "Satellit" receivers. At the same time, the first fully transistorised [[Zenith]] trans-oceanic receiver, also equipped with a turret tuner for band spreading, from U.S. production was presented. The Grundig **Satellite 205 Amateur** had the dimensions of 41 x 25 x 12 cm and a weight of 7 kg. The separate power supply could be stored inside the set, which could alternatively be operated from batteries. {{ :images:grundig-satellit205-amateur-dial.jpg?300|Grundig Satellite 205 Amateur}} The dial for the FM broadcast band, mediumwaves and the four general coverage shortwave bands from 180 - 10 m, is mounted on the right-hand side of the front panel, the row of range selector buttons next to it. The FM tuning knob is located between the dial and the speaker grill. The small on/off switch is located immediately below it, followed by the tiny field strength meter calibrated from 1 - 5, right next to it the AFC switch for FM. Below the small shortwave fine tuning knob is the main MW/SW tuning knob. The large loudspeaker is located at the left, behind a shiny grill. Above it, the window of the turret tuner with the bandspread dial of the selected shortwave broadcast band (49 - 16m), the bandswitch for the 6 ranges is located on the left face of the case. The volume control and the separate bass and treble tone controls are located on the top edge of the radio under the carrying handle. The single conversion design allows reception of the major international shortwave broadcasters; with only one available IF bandwidth, adjacent stations often cannot be separated sufficiently. The frequency dial has an accuracy of 10 - 20 kHz in the spread broadcast bands, in the general coverage ranges the currently set frequency can only be estimated very roughly, for station identification interval signals and spoken station identification must be used, the dial accuracy is not sufficient to reliably find a station once tuned again at a later moment. [[SSB]] reception is only possible with the optionally available external [[BFO]], with compromises in terms of frequency stability. Considering the conditions in the mid-60s, the Satellit 205 was a serious portable world band receiver with great audio quality, which was capable to receive the signals of the stronger international broadcasters from its telescopic antenna possible, even when travelling. {{ :images:grundig-satellit205-amateur-back.jpg?300|Grundig Satellit 205 Amateur}} The [[Satellit 205 Amateur]], which was produced in small series and allowed the amateur radio bands to be tuned in with the drum tuner instead of the international broadcast bands, had radio amateurs as its target audience, but these could often also make use of high-quality amateur radio receivers in their shack. ===== Technical principle ===== Single conversion superhet in analogue technology, spread SW amateur radio bands with drum tuner ==== Components ==== The set is equipped with semiconductors. ===== Technical documentation ===== ==== Development ==== {{gallery>:images?grundig-satellit-205-amateur*.jpg&0&80x80&lightbox&showtitle&titlesort}} ==== Further information ==== * [[https://www.radiomuseum.org/r/grundig_satellit_205.html|Grundig Satellite 205 on the website of www.radiomuseum.org]]
