    In the morning of Christmas Eve, December 24, we will try to start the old Alexanderson 200 kW transmitter, from 1924 and send out a Christmas message on VLF 17.2 kHz CW. The transmitter will be tuned up from around 08:30 (07:30 UTC) and a message* will be transmitted at 09:00 (08:00 UTC).

    Guests are welcome to attend the transmission at the radio station in Grimeton from 08:00 local time. The Alexander association will arrange Coffee and Christmas cookies, free of charge. No entrance fee.

    For those of you who can not attend, we will broadcast the event live from Grimeton,Sweden on our YouTube Channel.

    QSL-reports on the SAQ transmission are kindly received via:
    – E-mail to: info@alexander.n.se
    – or via: SM bureau
    – or direct by mail to:
    Alexander – Grimeton Veteranradios Vaenner,
    Radiostationen Grimeton 72
    SE-432 98 GRIMETON
    S W E D E N

    The SK6SAQ amateur radio station will be QRV on the following frequencies:
    – 7.035 kHz CW or
    – 14.035 kHz CW or
    – 3.755 kHz SSB

    Two stations will be on the air most of the time.

    *The world heritage site Grimeton is a living cultural heritage. All transmissions with the long-wave transmitter SAQ are therefore preliminary and may be set at short notice.

    Hello friends! Thanks for receiving the final report of the Christmas Morning sending 2018 per email from you. Your signal was received here in Horten / Norway loud and clear. I reported this to you per this web-page. Look further down on this page. Maybe I did the wrong way of reporting to you? … since I could not find my report in your final report 2018. Keep up all the good work. Best regards LA9ET / Geir, Horten, Norway

    Received the summary of the Christmas Eve 2018 reports, a little incomplete however, mine wasn’t included! I hope too many were not left out, otherwise we are left with an incomplete picture of coverage! Good transmission however, look forward to the next one!

    A copy of my report sent by email, to share the passion with the other SWL…
    I’m reporting from Italy to submite a reception report for the Christmas Eve SAQ Alexanderson alternator station.
    I read the fascinating story of the transmitter on the SWLing blog.
    As my current equipment doesn’t permit to reach the 17.2 Khz frequency, I used the Twente WebSdr receiver with the help of a Morse decoder for the message
    Listening time: from 7:30 UTC to 8:45 UTC
    Mode: CW
    SINPO: 55444
    Listening notes:
    At 7:45 UTC the transmitter tuned in with the periodical message VVV VVV DE SAQ
    At 8:00 UTC I was able to hear the full message (here I report what I received, with missing parts and my interpolation on the missing characters of received words):
    Thank you to share this tranmission using this valuable piece of technology and radio history. Bravi!
    My best wishes for Christmas and the New Year. I will check you nice and informative website for tne next transmissions.
    73 and Best regards

    Late report, but SAQ was received very strong in JN45sl with an unusual receiver, my ARM Radio project, based on the STM Discovery inexpensive evaluation board.

    Good signals here again this year, and a nice recording on the following link for your interest.

    Receiver was my trusty Perseus SDR, with about 500m of beverage cable….

    well here is a link for SAQ reception in scotland….

    After a couple of years without success (including sleeping through my alarm and missing it one year) I finally heard SAQs beautiful note direct on 17.2 kHz on Stonington Point CT this Christmas Eve. Solid copy at-93 dBm on a Wandell und Goltermann AT-611 Selective Level Meter at 400 Hz bandwidth. Antenna was an approximate 100 foot wire connected to my Tacoma 4X4 pickup’s HF mobile antenna feed point, laid on stones protecting the east side of the point from the ocean, about 10 feet from the salt water that surrounds the Point at the eastern end of the CT shoreline. The WuG was powered by a small 12V DC to 115 VAC inverter. Watched the streaming video on YouTube while listening. My fAvorite part of the video was hearing relays hammering in time to the keying accomponied by the flashing of arcing across the relaycontacts in the panels. What were the two small plank pieces of machinery they crew was operating early on the video? Oil and or cooling water pumps? After copying the massage I tried working SK6SAQ on 7035 kHz, but my 5 watts from a K1 Elecraft to a 40 meter Hamstick on the Tacoma could not break the pile up of EU stations.

    Interesting to see the number of people using SDRs to copy. Talk about two ends of the electronic communication evolution timeline – SAQ being copied on SDRs!

    Merry Christmas to all! Hopefully will have an SDR as well as the WuG on Stonington Point for a the next SAQ operation!

      Dear Christopher,
      Sorry for my late reply.
      The small plank pieces seen on the live video stream are used to start the circulation pumps in the liquid resistors. There are two liquid resistors used as variable rotor resistance for the electric motor.

      The liquid resistors consist of about 2 m high containers, in which electrodes made from stainless steel are dipped into the liquid consisting of water and sodium carbonate. The liquid level in the containers may be varied by “sluices” controlled from the control board (you can see the operator adjuating the liquid level several times during the startup phase). This regulates the resistance between steel electrodes and thus controlled the rotor resistance. The heat generated is cooled off in the liquor through a heat exchanger for cooling station facility. Read more about this and watch video (Swedish language) here:

    Dear guys,

    first of all : thank you for posting my QSL report with the telegraph picture at your front page !

    XMAS morning I tried to receive your signal again and used a different receiver but again the telegraph
    from W.Gurlt to write your message on a paper strip !
    It worked again !
    Signal was about -105 dBm, very clear and stable

    My station :
    antenna – 2 element beam for 7/10 MHz which works surprisingly well on VLF
    attenuator 10 dB
    up-converter to 10017.2 kHz
    RX – FT1000MP with 500 Hz filter in the 1st and 2nd IF
    homebrew AF detector for generating the pulses for the telegraph
    telegraph : W.Gurlt, Berlin, 1880

    Thank you very much for that successful operation – I’ve enjoyed it !

    I regret the delay, but on these dates you always have to travel to see the family.
    This year I was able to listen to your broadcast with an emblematic receiver VOLNA-K of the 50s of Soviet construction. For me it was a curious test, I was not sure if I could receive the broadcast.
    My QTH is Galliners 20km north of Girona City. LOC JN12KD


    I used an active antenna Miniwhip. I could receive your signal although a little weak, I suppose due to the propagation. The receiver does not have S-meter, but I pass a YouTube link where you can listen to how you received with this old receiver. It is a fragment made with my mobile phone: https://youtu.be/zboPH73D_bs

    Thankful for your work and my best wishes on these dates.

    Hello dear friends,
    SAQ was 579 by ear, on my loop here in the Netherlands in JO22na
    After I tuned my loop antenna to the signal of SAQ, I wanted to make room for a paper, to take up the message later.
    When I moved my breadboard with the loop amplifier, the circuit went dead and did not come a live again, what ever I did.
    At first I was very disapointed. But later I realized, that I received SAQ and could give a very good 579 report.
    Thank you for the transmission.

    Thank you for putting SAQ on the air. It was a real thrill to hear CW at 17.2kHz. Most of my radio is at the microwave end on EME but I built a PA0RDT mini-whip with a 680mm whip mounted 2m agl feeding through a MW band-stop filter into an SDR IQ running the Spectravue software in order to hear this unique station! I recorded the whole message and I believe the SNR to be about 17dB. My main problem was lines from the PC but with a narrow bandwidth 100Hz I got rid of the worst.
    Best wishes to all for Christmas and 2019.

    I wanted to acknowledge reception of your signal on 17.2 KHz. on 24-December. I heard the “CQ” between the hours of 8:02 and 8:04 UTC. My receiving equipment is a Watkins-Johnson 8711A receiver with an indoor wire loop antenna. Signal strength was approx. -110 dBm.
    Thank you! It was a pleasure to finally hear your signal here in the United States!

    Very good signals here in Holland (NE) in JO33JB. Never heard the signals so loud. I think propagation was very good this time. We were in the field far from buildings etc.. 30 dB above the noise on a miniwhip at 4 mtrs, 38 dB above noise on a large loop with a diameter of 35 mtr, hanging at 2-3 mtrs high with a little OP27 amplifier.

    Thank you for the transmission today! Received here in the northwestern part of Germany with an SSB LAN-SDR, signal strenght was about -110 dBm (S 4 – 5). Your message was easy and complete readable (R5). My antenna is a 27 wire L configuration about 8 Meters above ground, not tuned to VLF. I used in this configuration a homemade converter with S042P IC, wich converts the signal to the 10 MHz range.

    Also my Siemens E311 with the SO42P converter give a very good reception (RST 559) of your transmission today (in interaction with the converter an the vertical above).

    Test transmission starts ca. 7.35 UTC with “VVV de SAQ SAQ SAQ” etc. XMAS-Message follows at 8.00 to 8.04 UTC.
