Beim Meersburg W von 1950/1951 gab es offensichtlich vier verschiedene Modelle: 1. Meersburg W: Dies ist die Standardausführung, nur mit AM (2xKW, MW, LW) ohne UKW 2. Meersburg W-US: Mit ab Werk eingebautem UKW-Superhet-Vorsatz UKW-S. Nicht im Handbuch des Rundfunkhandels aufgeführt! 3. Meersburg W-UA: Mit ab Werk eingebautem UKW-Pendler UKW-A (UA), Röhre ECH43. Diese Ausführung ist im Handbuch des Rundfunkhandels 1950/51 neben dem einfachen Meersburg angegeben. Die zum jetzigen Zeitpunkt eingestellten Bilder beim Modell gehören definitiv zum UA2! 4. Meersburg W-UA2: Mit ab Werk eingebautem UKW-Pendler UKW-A2 (UA2), Röhren EF42, EF41. Dies ist offenkundig das Nachfolgemodell des UA mit verbessertem Pendelvorsatz. Gerät habe ich zur Neuanlage vorgeschlagen. Die Typen 2, 3 und 4 hatten die Zusatzbezeichnungen nicht direkt auf der Rückwand eingestanzt, es wurden braune Papierzettel hinter die Bezeichnung "Meersburg" geklebt, eine Praxis, die SABA offensichtlich häufiger bei Typenänderungen verwendete, z.B. die ersten Geräte der Serie W5, die zu W5-3D geändert wurden. Auch beim Freiburg 3DS gibt es Modelle, wo das "3DS" erst nachträglich angebracht wurde. Das war wahrscheinlich die große "Umbauaktion" zur Funkausstellung 1954, als SABA nachträglich die Seitenlautsprecher einsetzte. Bitte durchforsten Sie Ihre Bestände, denn vom Typ 3 (Meersburg W-UA) fehlen bisher Bilder! |

this Question was posted to SABA Meersburg W4, but schould be here: My apologies for the incorrect model designation in the Title The FM unit is installed in the Meersburg W according to the rear panel Reviewing the schematic for the model 840-780a (dated 6.6.50) and presumably for radios produced in 1950/51, I have not completely understood the function of the right front knob and the lower right rear knob on the side of the radio. I believe the use and function of the lower right rear knob is the same as that of the Saba S455WK that I have. I believed the right front knob, however, is used to select the Mode of Operation as follows: with 5 possible selections, I estimated the Modes to be--- 1. TA only 2. All except UKW operation 3. UKW only 4. UKW muting 5. Sensitivity selection (weak or strong) and EM4 circuitry correlation I realize there were many issues being resolved, after the Copenhagen convention, and improvements to reduce interferences and allow for interstation suppression of "excess noise". The use of the EQ80 FM discriminator (the phase detectors) appears to be somewhat brief in FM circuit developments, and also possibly added to the earliest models to reduce the number of tubes in the radio. I would be most appreciative to determine the proper use and function of these knobs. Respectfully, Robert Dieser Beitrag wurde am 10.Aug.05 14:32 von Robert Sarbell editiert.

Dear Robert, i took a look at the Circuit Diagram and the Technical Data Sheet of the Meersburg W. The Data Sheet says, that the set is Equipped with the SABA MHG Circuit, to set the Bandwith of the IF Amp to 3, or 6, or 10 kHz. This Switch is combined with the Switch to select the "Sound" of the AF Stage. This Switch has 5 Positions, and is shown in the upper right hand section of the Circuit Diagram. ( 840-760d). There is a Text about "SABA MHG Schaltung" in the RM, in German. The Other Switch has 6 Positions, which are TA ( Pickup ), Long wave, Medium Wabe, Short Wave 2, short Wave 1, and UKW. There is a Table shown in the lower left hand Corner of the diagram, which shows , which of the Switches is closed at what Position. The Switches are identified by S1 to S18, and You will find the Number beside each switch. The UKW Unit is connected to the 5 port solder Strip, shown in the Circiut Diagram just above the right EAF42, and described " z. UKW-E " this is, what i cold find out with the Informations on the Meersburg W. Hope this Helps, Henning Oelkers, Berlin |

Dear Henning, Thank you again. I certainly saw the coupled switch assemblies in the upper portion of the schematic, but had not correlated the respective circuits in the UKW schematic. to provide the 3, 6, or 10kHz selection of sound to the AF stage. I shall review the SABA MHG Schaltung text that you referenced. You have clarified all that I missed. Respectfully, Robert |

Dear Henning, I knew there was a NOTE fo the technician when he is going to perform alignments of the IFTs, that the tools should be made from the PVC-type material in order not to demolish the core of the spool. Even the dimensions are provided to make your own tools for the different spools in the IFTs - very helpful. I also reviewed some of the text but it is VERY slow for me unless I use the Babelfish translator. However, the files are not in the text format to copy and paste into the babelfish. I have solved my problem with the transliteration of the SABA MHG files into a "text document" that is translatable. I find the material to be as interesting as stated by the lecturer Herr Hermann Freudenberg(GFGF, Netphen; 2003) in June 2003. I have already advised my very good friend and neighbor to the south about the Stufen 1-2-3 for the Schmal, stufen 4 for the mittel, and stufen 5 for the breite selections; and the selectable AF stages. . . . . . .knob pulled out and knob pushed in. My Saba S455WK right knob has the "in-out" functions, but the rotation is through a pot and there are NO detents. Respectfully, Robert |
