QSL SAQ Grimeton Alexanderson Day 2024 on 17.2 kHz

e QSL SAQ Grimeton Alexanderson Day 2024

June 30th was the celebration of Alexanderson Day (the day named after the inventor of the Alexanderson Alternator) at SAQ. Despite mid summer conditions reception was quite good as was also the case last year. This resulted in another SAQ Grimeton QSL.

A nice feature of these SAQ broadcast is that they broadcast the event via YouTube with a live chat channel where DXers from around the world compare how well they receive the station.

QSL SAQ Grimeton Xmas 2023 on 17.2 kHz

Of the 4 SAQ Grimeton broadcasts I was able to listen to in 2023 this was by far the best reception with a clear CW signal, S4. A week later I received their e-QSL!

SAQ Grimeton is a former wireless telegraph station in Sweden. It generates radio signals using an AC generator (called an alternator) designed by the Swedish engineer Alexanderson. This technology was used prior to the development of vacuum tube oscillators. You can learn more about the history of this station and its planned transmissions on the website of the Alexander assocation.

QSL SAQ Grimeton UN-day

I received this e QSL from SAQ Grimeton, Sweden, for the reception of their UN-day transmission. The event took place on October 24th, at 15:00 UTC on the usual 17.2 kHz. I struggled to get a readable signal at my home QTH this time. So I used the Twente SDR as an alternative. Funny thing is that contrary to my expectations their previous transmission around noon mid summer resulted in a much better signal.

QSL SAQ Grimeton 17.2 kHz
e QSL SAQ Grimeton 17.2 kHz Alexanderson Day 2023

QSL SAQ Grimeton Alexanderson Day

I received an e- QSL from SAQ Grimeton, Sweden, for their transmission on 17.2 kHz to celebrate Alexanderson Day.

Ernst Alexanderson was the inventor of the Alexanderson alternator, a rotating machine used for the generation of a high frequency alternating current, which could be used to produce an electromagnetic wave for radio transmissions. The first alternator based stations were installed in 1906 for long wave telegraphy. In the early 1920s vacuum-tube transmitters came available, replacing the alternators. The Grimeton historical station is the only station in the world that still operates on the basis of an alternator.

I was a bit worried that it would be difficult to receive SAQ on VLF 17.2 kHz at noon in the middle of the summer. Not that I know a lot about VLF propagation. But the signals came through in much better quality than last time I received them on World Radio Day on February 13th this year.

QSL 7S6WRD Grimeton HAM Radio

During the UNESCO World Radio Day event of February 13th, 2023 a special HAM station was in the air. I received it in CW on the 14 MHz band. It was a long time ago that I decoded CW, but with record/play back I was able to collect sufficient details for a QSL of 7S6WRD Grimeton, Sweden.
My guess is that the station normally operates as SK6SAQ (with SAQ identical to the Grimeton callsign) but was under a special 7S6WRD callsign for this event (with WRD obviously referring to World Radio Day).
