  • Folks!

    Am Sonntag 24. Oktober ist SAQ abermals on Air. Nachfolgend, hoff' das klappt so, ein Text den ich heute morgen im ARRL Newsletter gefunden habe. Zuvor habe ich von der Veranstaltung nirgendwo was gelesen daher dieses Posting. Ev. interessiert sich ja auch sonst jemand dafür. Falls das HTML zusammengehaut wird einfach den Links folgen...

    UN Day Transmission from Sweden's SAQ Set for October 24

    On United Nations Day, Sunday, October 24, the vintage and historical Alexanderson alternator in Grimeton, Sweden, with call sign SAQ, is scheduled to send out a message to the world on 17.2 kHz CW. The events of the day will be livestreamed on YouTube starting at 14:25 UTC. Transmitter startup and tuning will begin at 1430 UTC, with the message transmission to follow at 1500 UTC.

    This year's message was drafted by Swedish human rights lawyer and sustainability expert Parul Sharma.

    Dating from the 1920s, the Alexanderson alternator -- essentially an ac generator run at extremely high speed -- can put out 200 kW but typically is operated at less than one-half that power level. Once used to provide reliable transatlantic communication, it is now a museum piece and only put on the air on special occasions.

    The transmitter was developed by Swedish engineer and radio pioneer Ernst Alexanderson, who was employed at General Electric in [Blocked Image:]Schenectady, New York, and was chief engineer at the Radio Corporation of America.

    Six 400+ foot towers with 150 foot crossarms support a multi-wire antenna for SAQ. The actual signal radiates from a vertical wire, one from each tower.

    Amateur radio station SK6SAQ will be active on these frequencies: 3.535 MHz CW, 7.035 MHz CW, 14.035 MHz CW, 3.755 MHz SSB, and 7.140 MHz SSB. QSL SK6SAQ via email to, via the bureau, or direct to Alexander - GVV, Radiostationen Grimeton 72 SE-432 98, Grimeton, Sweden. Two stations will be on the air most of the time.

  • Die SAQ-Sendung kam hier in JO61AB sehr laut und klar an. Empfänger war der Belka DX in Kombination mit dem VLF-Konverter von SV2CZF und einer MiniWhip im Garten in 4m Höhe. Ich habe die Aussendung als Video aufgezeichnet. Der Sound kommt also direkt vom Lautsprecher des Belka und man kann den Höreindruck nachvollziehen. Der Konverter hat einen Frequenzoffset von 1.8 kHz, daher musste ich 15.4 kHz am Belka einstellen. Hier der Link zum Video:
