SAQ Transmission
Hi,
I haven't seen any mention of the transmission yesterday afternoon from the Alexanderson transmitter SAQ at Grimeton, and I unfortunately missed it. For anyone who also missed it, there is a link to a video of the startup and transmission given on the Summits on the Air reflector. Kind regards Dave G0ELJ |

Re: SAQ Transmission
Hi,
Just a Datong VLF converter in front of an FT857. and a short wire antenna at the moment. When I was in Birmingham I used to have a Marconi CR200 and a home made VLF loop or a 50 foot wire, and received SAQ pretty well. Have missed every SAQ transmission in the three and a half years since moving here, so don't know whether I would receive it or not, although I can hear the US naval transmissions a little higher up (and I am a bit closer) ! Kind regards Dave |

Re: SAQ Transmission
I too forgot (shame you all cry) this time, usually received using my Wellbrook loop and an SDR. I was sent a QSL card (via e-mail) last time, printed it and is now on display on my wall at work. When fellow engineers and scientists* visit my domain it is a start for a conversation, only one person said "that's sad, old tech.", their loss.
*Scientists, we have a lot here and I am an interface twixt hem and reality, i.e. "make that work", great job! |

Re: SAQ Transmission
I watched the start up live on their Youtube Channel, then heard the transmission using my SDR Play RSP2 and SDR Uno. Long wire antenna.
Pity they only stayed on for 10 minutes. John |

Re: SAQ Transmission
The generator frequency is controlled by liquid-conductor variable resistors. The videos don't say much about these, but they were originally used to provide telephone modulation during the war.
There's some nice historic notes and pictures in Grimeton - The Movie

Re: SAQ Transmission
Hi,
There appears to be another transmission today from SAQ Grimeton at 1800. I'm not absolutely certain, as the date is coloured red on their site, and the Swedish word next to 18.00 means nothing to me, but worth checking for anybody in a position to receive 17.2 kHz. Kind regards Dave |

Re: SAQ Transmission
Hi Graham,
Many thanks for the info, I thought it might be the 'Christmas Transmission' I'm a bit relieved actually, as I've been wondering what to use for an aerial! Xmas Greetings and stay safe, Kind regards Dave |

Re: SAQ Transmission
That is correct Mick, I read the same, possibly on South Gate Amateur Radio News.
