- The VLF transmitter, with call sign “SAQ” at Grimeton Radio Station, was put into commercial operation, with transmissions across the Atlantic ocean, on December 1st 1924.
One hundred years later, SAQ is still operational and will be started up on Christmas Eve morning, December 24th, to deliver a Christmas greeting to the World.
SAQ can be heard on VLF 17.2 kHz CW, and the entire event can be followed live here:
08:20 CET (07:20 UTC): Live video from World Heritage Grimeton Radio Station begins
08:30 CET (07:30 UTC): Startup of the Alexanderson Alternator SAQ from 1924.
09:00 CET (08:00 UTC): Transmission of a Christmas message from SAQ.
*The world heritage site Grimeton is a living cultural heritage. All transmissions with the long-wave transmitter SAQ are therefore preliminary and may be cancelled at short notice.
Just drove all the way from England just to watch this in person this morning. Thank you for doing it in English!
Scandinavians usually speak pretty fluent English. We are fortunately a tad to small to use dubbed TV/film, and it helps a lot.
Greetings and Happy Christmas from Tangier Morocco.
We visited the station last year, took our sailboat into Varberg and visited by bus.
Great to see the station on air today!
Best wishes to you all, crew of Sailing Vessel Gabrielle. G8WVW/mm
Thank you so much for this wonderful video. Former RNW here, I wish you all the best in 2025!
Thank you for this lovely event. Your signal was received at 25dB above the noise in Munich, Germany using an active miniwhip antenna and I just uploaded a youtube video showing it. Have a great Christmas !
Impressive!!!! Congratulations on the 100th Station Anniversary!!! Perfect Hand sent CW!!!! Merry Christmas to all de WP4BKJ, Aguadilla, Puerto Rico
Thank you!
¡Excelente video! Muchas gracias y saludos desde la Ciudad de Buenos Aires, Argentina.
Utmärkt video! Tack så mycket och hälsningar från staden Buenos Aires, Argentina.
Great video! Thank you very much and greetings from Buenos Aires, Argentina.
Thank you for your commitment and for giving me a reason to make a ferrite antenna and drive out into the field on Christmas morning at almost 0°C to listen to the station! I've also uploaded a short video of it. Merry Christmas!
Ich habe dein Video gerade gesehen. Ach, ist das aber schön! Danke für's Teilen.
Impressive. A very clean fist, OM. It sounded like you might have started to get tired in the last half. But, I could listen to you all day long. HI
73 & Merry Christmas
and Happy Christmas and thanks to all the volunteers who keep this wonderful World Heritage Radio Station running! Excellent hand-keyed CW also in the Christment message.
Thrilled to hear SAQ this morning for the first time. Excellent signal about 579 on a RA17W with a RA137 VLF adaptor in IO91 UK (30KM NW of London). Only using a 30m half square as receive antenna because surprisingly it gave the best s/n. Better than a loop and larger 160m invL. Lots of switchmode hum birdies and other RFI down these low frequencies it seems. Glad it did not need a 17KM long beverage!
I received it on a 30cm 40-turn tuned coil plugged directly into the soundcard of a computer.
I totally forgot to try and listen for it this year. I did hear it 3 years ago, here in Pauls Valley, OK. Very faint, but just discernable.
Alles Gute, frohe Weihnachten und eine lange Funktionfähigkeit dieses wundervollen Senders wünscht Ingrid Monika, DK2IM aus Germany, Oberhausen-Schmachtendorf 73
Merry Christmas and Happy New Year Greetings from Woodbine, Maryland in the US! 73, DE AB3A
Fascinating video. I did not realise that there was still an operational mechanical transmitter
He is good! Flawless sending for good copy! 73 and Merry Christmas!!!
I was there a few years ago. If you can, do so as well! It is an unbelievable experience to be a part, however temporary, of this radio history.
Thank You to All SAQ Team! Merry Christmas and Best Regards! 73' Gianluca IK0SME
Greetings and happy Christmas and new year from Jaén (Spain). Beautifull transmission !!!. EA7KAU Justo.
Every time again it's just fascinating to see this machine starting and working. 🤩
Thank you for all you do, and Merry Christmas from Renton, Washington, USA! ❤️🎄
God sees and remembers everything then there will be the Judgement.
The God has nothing to do neither with magic nor with pagan holidays.
There is no evidence that Christ celebrated his birthday anniversaries, but king Herod executed John the Baptist on his "birthday".
This is the God's word,
Deuteronomy 12: 29-32: "When Jehovah thy God shall cut off the nations from before thee, whither thou goest in to dispossess them, and thou dispossessest them, and dwellest in their land; take heed to thyself that thou be not ensnared to follow them, after that they are destroyed from before thee; and that thou inquire not after their gods, saying, How do these nations serve their gods? even so will I do likewise. Thou shalt not do so unto Jehovah thy God: for every abomination to Jehovah, which he hateth, have they done unto their gods; for even their sons and their daughters do they burn in the fire to their gods. What thing soever I command you, that shall ye observe to do: thou shalt not add thereto, nor diminish from it."
Leviticus 20: 27: "A man also or a woman that hath a familiar spirit, or that is a wizard, shall surely be put to death: they shall stone them with stones; their blood shall be upon them."
Levticus 19: 31: "Turn ye not unto them that have familiar spirits, nor unto the wizards; seek them not out, to be defiled by them: I am Jehovah your God." (ASV)
This is a christians' way,
Acts 19: 19: "And not a few of them that practised magical arts brought their books together and burned them in the sight of all; and they counted the price of them, and found it fifty thousand pieces of silver."
But, the inhabitants of World Sodom run to fortune tellers and astrologers while blessing them in the name of God...
The problem is Devil runs the world. He is liar and murderer. This is the reason why deception and violence are everywhere. This is the reason why Hitler got the power, but Christ was executed as "blasphemer" and "rioter" by denunciation of clergy. This is the reason why the whole world is Sodom.
That's why we've got the Gospel about the God's kingdom. Jehovah would put everything in order. He has anointed the king, Jesus Christ. The dead will be resurected and we'll meet our loved ones again! :-)
This is just very very impressive. Amazingly smart in that time.
Feliz Navidad a todos.
Gracias por existir.

I've no receiver now since my frequency synthesiser failed so I watched it here today (25th).
Perfect sending, I sat here and read it.

god jul from holland nederland much work on the transmitter on air thanks a lot greetings from Jan,
I've seen these videos many times and still get a thrill. I marvel at a 100 year old machine still operating.
There's a guy on UA-cam demonstrating a 1956 Bendix G15 electronic computer running, the oldest such in North America & perhaps only of its kind operating in the world.
That's David from Usagi Electric. I've been following the amazing journey of him getting that old tube based monster operational again. He is quite the genius on antique computers!😉👍👍👍
@danw1955 me too, it's great fun. Amazing that thing works as does his home built vacuum tube computer. I also enjoy Paul Carlson et al getting these 80 year old radios & TV sets going.
Merry Christmas and a happy new Year! OK2UDG RST 557 Marek

Nice job
Great show! Thank you. 73 de Guido, DF9PW/N5MQD
Just imagine going through the start up steps… then a QSO asks to go QRP
Sadly it seems my JRC NRD-535DG is not able to receive this signal despite a 400m wire. It receives 60 kHz from England ok but it loses sensitivity below 30 kHz
I use a VLF converter that receives from 1khz to 500khz and upconverts to 28Mhz.
73 and Merry Christmas G7HFS/PA3IKH
Is it possible to get a diagram of the transmitter ? I'm curious what all the machines are.
Awesome!
