A quick update on my previous post on DSC and NAVTEX in Sweden. Following my QSL from JRCC Sweden I wrote an email to Stockholm Radio with a little query (and a reception report of Stockholm Radio on 2187.5 kHz).
Bjorne from Stockholm Radio was so kind to explain the current situation:
All transmission of weather and MSI (maritime safety information or navigational warnings) on MF are done by “Sweden Traffic” which is part of the Swedish Maritime Administration: Sjöfartsverket
All Emergency monitoring (GMDSS/DSC) is done by JRCC Sweden, located in Gothenburg. JRCC Sweden is also part of Swedish Maritime Administration: Sjöfartsverket. For this purpose JRCC Sweden has access to all Stockholm Radio facilities. I received my QSL for JRCC Sweden via email@example.com
In addition to providing VHF telephone services Stockholm Radio (www.stockholmradio.se ) is only responsible for coastal weather transmissions on VHF during summertime (June 15th – September 15th according to their website).
Göteborg and Stockholm Radio can be received regularly on 2187.5 kHz with DSC messages. As I already had QSLs from the 80-ies for I didn’t bother to send a reception report and QSL request for these two stations. But then I saw a QSL from Artur at MaresmeDX for JRCC Sweden. And I wondered how they are actually organized these days.
Within an hour of sending my reception report for a reception of MMSI 002653000, Göteborg Radio on 2187.5 kHz to firstname.lastname@example.org I got an answer:
So it seems that everything on MF is now under the jurisdiction of JRCC Sweden. The HF band isn’t covered anymore. And I guess that the name Stockholm Radio is used for VHF DSC watch and weather broadcasts: https://stockholmradio.se/ .
In the 80-ies you could listen to a couple of stations on MF. In addition to Göteborg (SAG) and Stockholm Radio (SDJ) I remember Karlskrona (SAA), Härnosand (SAH) and Tingstaede (Visby, SAE). The nice thing was that they had matching set of QSL cards. But although I heard all stations, I managed to get the QSLs for Göteborg and Stockholm Radio only…
On Christmas Eve morning, Sunday December 24th 2023, SAQ Grimeton is scheduled to be on the air, to send out the traditional Christmas message to the whole world, using the 200kW Alexanderson alternator from 1924, on 17.2 kHz CW.

Test transmissions We are planning to carry our some test transmissions on Friday, December 22nd, approximately between 13:00 CET (12:00 UTC) and 16:00 CET (15:00 UTC). SAQ will be on the air shorter periods of time during this interval, when we will be carrying out some tests and measurements. Your comments are welcome to email@example.com.
Radio Igloo was on air last weekend (and I told you so!). This time from Europe (my previous QSL was for a reception via WRMI). On Saturday, November 11th, they were present on three frequencies via three different Free Radio stations. I managed to pick up the one on 4975 kHz, but only the first 30 minutes. Conditions were poor and I suffered a lot of QRN on my holiday location in Exloo, which didn’t help either.
A day later I heard them on 6375 kHz (which was the only frequency they used that day). Fortunately quality was much better this time, and I could listen to the entire show which featured a nice selection of music, mainly picked by participants on the Westcoast DX Club event that was held at the same time. They were together 25 km North East of Gothenburg, Sweden, with some nice antennas, including a 300 m long Beverage. You can see the expedition on the QSL – I’ve been on many DX weekends, but never one where the beds were directly behind the receiver 😉!
According to Shortwave DX blog, the 4975 kHz transmission was via Free Radio Akenzo, and the 6375 kHz via Radio Mexico. I sent my report to firstname.lastname@example.org.
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.
After an extended period of building maintenance, World Heritage Grimeton Radio Station has scheduled SAQ to be on air on UN-Day, Tuesday October 24th 2023 at 17:00 CET (15:00 UTC), to send out a peace message to the whole world, using the 200kW Alexanderson alternator from 1924, on 17.2 kHz CW.
Transmission & YouTube Live stream 16:25 CET (14:25 UTC): Live stream on YouTube begins. 16:30 CET (14:30 UTC): Startup and tuning of the Alexanderson Alternator SAQ. 17:00 CET (15:00 UTC): Transmission of a message from SAQ.
From 23rd – 25th September I participated in another Coordinated Listening Event. This time the challenge was to try to log a beacon on each frequency between 275 and 425 kHz. So maximum 151 NDBs. In total I logged close to 380 beacons on 127 different frequencies. Of course I try to get a couple of QSLs in return for this effort and like last time I decided to focus on Sweden (there is no way that I’m going to send out 380 reception reports!). The first QSL came in today from Borlänge Airport. NDB BL-421 is located 1132 km from my home QTH.
