The wonderful world of listening to the radio
December 1st, 1924, was the day on which the VLF transmitter in Grimeton with call sign “SAQ” was taken into service. The station connected with telegraphy transmission across the Atlantic to Riverhead and Rocky Point on Long Island, New York.
The quality of the Centennial Transmission was exceptionally good… better than any of my SAQ receptions so far.
The fifth and final beacon of this series. A QSL for NDB OD-322 Örnsköldsvik Airport. Not in Lapland but close. Örnsköldsvik is the first airport in the world to have a remotely controlled air control tower. It is controlled from Sundsvall–Timrå Airport.
Below please find the excerpt of the email to QSL the Lapland beacons. Thanks to Chris from AVISEQ. Feel free to contact me for the QSL address by dropping a comment!
The fourth beacon from the Lapland region in Sweden. Chris from Aviseq sent me an email to QSL NDB DK at 328 kHz, Vilhelmina. The beacon serves as navaid for South Lapland Airport, 1547 km from my QTH.
As is the case for Lycksele and Hemavan Airport there are daily flights from Vilhelmina to Stockholm Arlanda. Vilhelmina itself has a population of only about 4000. Apparently the huge distances to be covered in Sweden justify the airport.
Another two NDBs from Lapland, Sweden. NDBS NUT on 325 kHz and SUT on 342 kHz serve as navigation aids for Hemavan Tärnaby Airport. The distance to my QTH is 1632 kilometers.
Hemavan and Tärnaby are ski/winter sport resorts. From the airport, which is adjacent to Hemavan, you can see the slopes in the background. Amapola (aka Populair) Airlines operates flights between Hemavan and Stockholm Arlanda.
My reports were confirmed by Chris from AVISEQ.
Chris from Aviseq, who also QSL-ed my reception of the beacons WU and VNA for Umea Airport, was so kind to confirm my reception of the beacon OL for Lycksele, Sweden on 320 kHz by email as well.
Lycksele Airport is located in South Lapland, a sparsely populated area in the north of Sweden. The distance to my QTH is 1590 km. Amapola operates daily flights to Stockholm from Lycksele Airport.
To give you an impression what it means to dig such a signal out of the noise with Pskov software I added the above picture. In the yellow/black panel you see how OL is received… Every line from left to right is a capture of the cyclic signal. As you can see the first minutes/cycles offered a better signal… The aggregate is a clear OL identification in morse code.
A QSL from NDB VNA-354 Vanja, a navigation aid for Umea Airport in Sweden.
Earlier I received a e-QSL for my reception of the other NDB for Umea Airport WU-329. The engineering team that reached out to me promised to send a QSL card by mail for the other beacon VNA-364 once they had completed their maintenance visit and were able to take a few pictures. Last week I received it!
It is always nice to get a picture of an NDB. Sometimes I’m able to trace them on Streetview in Google Maps. But as Christoffer from the Engineering team explained: no chance for VNA which is pretty much off the beaten track. The picture below shows the access path to the beacon.
The transmitter is SA-100D transmitter with 100 Watt. Christoffer told me it’s the same as WU uses and the stations are near identical in terms of looks.
Almost exactly a year ago I wrote a post on my reception of two beacons for Umea Airport: WU-329 and VNA-364. At the time I received a polite “thank you email” from Swedavia, the operator of Umea Airport. But hardly a QSL.
Two weeks ago I was contacted by engineers working at AVISEQ, the company responsible for the maintenance of the navigation aids and ATC communication/systems in Sweden. They had read my post and prepared the above eQSL for NDB WU-329 me and there should be a QSL for VNA-364 on its way. Of the latter beacon I also received some nice pictures, as the team was doing some maintenance on VNA. I will post them together with the QSL.
Stay tuned for more!
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.
The Sveriges DX Förbund, SDXF (or Swedish DX Assocation) can be heard with a program via Channel 292. December 26th I heard them on 9670 kHz with a special Christmas edition. Unfortunately the program was mainly in Swedish, with a few minutes in German language only. Reception report should be sent to qsl@sdxf.se. QSL manager Gert Nilsson sent me an email confirming that my report was received, and a few weeks later I received their nice QSL card by mail.
Not sure when they are on the air again (they had a show on World Radio Day yesterday), so please check the websites of SDXF or Channel 292 for more information.
Asfalttelegrafen was on air from December 23rd until January 5th. I tried a couple of times around Christmas, but I couldn’t get a decent signal here in Woerden. Tracking some KiwiSDRs I learned that the signal reached the German coast, but then it quickly deteriorated.
On January 4th however I was lucky however. And although a strong noise source on 1495.25 kHz forced me to notch everything between 1000 and 1500 Hz I could recognize the various titles played and picked up a clear ID (at 24 secs in the clip).
A day later I received a lengthy and detailed email QSL from Torleif Roos, who is DXer and HAM operator as well. Asfalttelegrafen is located in Ludvika, Sweden, 1097 km from my QTH. I noticed the name is sometimes also spelled as Asfaltstelegrafen.
The station got its name from “Asfalttelegrafen”, a program on the Swedish National Radio 3rd program on FM around 1975. In the late Sunday nights before midnight it brought rock music. Unfortunately private individuals can’t obtain a permanent license in Sweden, so Torleif has to apply for a 14 day license every time he want’s to broadcast. More information can be found on the radio sweden international website.
The transmitter is a 1 kW Hercules. It is connected to a “L” antenna, 48.5 meters long above an earthplane created by 16 cables of 50 meters each. Broadcast times were 20:00 – 03:55 h UTC, which is the window created when Radio Moldova is not in the air. During those hours the frequency is empty in Europe, with the next station being in Iran.
