Award for reception of International Space Station ISS

April 22, 2025 / Peter Reuderink / 0 Comments

A few times per year the International Space Station (ISS) has an event in which they transmit SSTV messages in the amateur band. Between April 11th and 16th there was such an event, dedicated to “Humans in Space”. Note that April 12th, 1961 was the date of the first human space flight with Yuri Gagarin.

The frequency used was 145.800 MHz in the 2 meter amateur band, which is covered by my ICOM R8600 so I decided to give it a try. I used the AMSAT site to get information when the ISS was flying over. Each morning there were 5 passes, about 1.5 hr apart. During a pass the ISS would “theoretically” be in visible range for 6 to 10 minutes. As I didn’t have a 2 meter band antenna I just pointed my 5 elements 100 MHz Yagi (6 m elevation) westward to see what would happen.

The Amsat site provides a tool to predict ISS pass times.

On the first try I was lucky. The SSTV broadcasts were in FM and PD120 mode, which took me some time to sort out. Good thing that I made an SDR recording so I could leisurely experiment with fine tuning the decoding. Now each picture takes 2 minutes to send, followed by a pause of 2 minutes. And while the ISS is “theoretically” in sight for 6 to 10 minutes, the reality is that at my location I don’t have a free view from west to east. On the west there are houses and somewhat further away a 9 story apartment tower. But east is worse with a nearby 5 story apartment blocking my view. Combined with the directional properties of the antenna it meant that I never managed to have more than 2 minutes of good quality reception each pass. As you can see in the pictures below:

But good enough to upload my pictures to the ARISS website and apply for an award which was almost immediately returned (Tip: do check you spam email box, as that’s where my copy landed!).

Award for my reception of ISS during the “Humans in Space” event.

Now the problem is that I don’t have a reliable source for upcoming ISS events. The ARISS website doesn’t always seem to mention them. I got my information form the AMSAT-UK website, which had links to various relevant pages. So suggest you follow them if you are interested to try for yourself.

QSL BR6 Bodegraven Reeuwijk 107.8 MHz

April 18, 2025 / Peter Reuderink / 3 Comments

Another nice QSL from a local radio station in The Netherlands. This time from BR6, the local station for Bodegraven & Reeuwijk. John Bekker was so kind to confirm my reception report. He wrote that they have no QSLs, but in thThey have been heard as far as Wolfsburg, Germany, which isn’t bad given their power of only 50 Watts.

BR6 is also part of the RTV Midden Holland group (see my post on RTV Krimpenerwaard). Their antenna is located on an advertising column in an industrial park in the south of Bodegraven. Just over 10 kms from my QTH!

I hate these ugly advertising columns, but if you put a radio antenna on it, I can live with it😉

By the way… did you know that Bodegraven, like my own QTH Woerden is situated along the old river Rhine? Which was once the northern frontier, the “Limes” of the Roman Empire…

QSL RTV Ronde Venen 106 MHz

April 16, 2025 / Peter Reuderink / 0 Comments

Back on my journey exploring the local FM radio scene:
Another nearby local FM station is RTV Ronde Venen. They have two frequencies in use. I listened to their 60 Watt transmitter from Kockengen on 106 MHz (8 kilometers from my QTH). The other frequency is 105.6 MHz from Mijdrecht with 50 Watts. My report was confirmed within a day with a f/d email reply.

I heard and QSL-ed this station with a similar name “Radio Ronde Venen” in 1990 (no TV then apparently). This was the local radio from Mijdrecht, in the municipality Ronde Venen which was established when Mijdrecht, Vinkeveen, Wilnis and Waverveen merged into one muncipality in 1989.

Kockengen however is part of the the municipality Stichtse Vecht. With RTV Stichtse Vecht they were broadcasting on 106 MHz from Kockengen and 105.3 MHz from Maarssen. But since the start of 2025 they decided to join efforts with RTV Ronde Venen. Financial considerations with regards to investments in the studio apparently played a role. As I described in my post on RTV Krimpenerwaard it is another example of the trend in which local stations merge into more regional entities… Not sure what happened to 105.3 MHz though, that transmitter seems to be taken off the air.

QSL Klokradio Molenaarsgraaf 107 MHz

April 16, 2025 / Peter Reuderink / 0 Comments

Best kept secret in The Netherlands is the beautiful Alblasserwaard. Even on public holidays the roads are quiet, perfect for cycling through a classic Dutch Polder scenery…

I heard Klokradio the local FM station in the Alblasserwaard on 107 MHz with 200 Watts from the village of Molenaarsgraaf. The distance is only 24 kilometers, but reception was a bit compromised with RPL FM from my home QTH on the adjacent 107.1 MHz.

Kees from the Technical Department (who is a HAM operator) was so kind to send me a detailed confirmation email:

Dear Peter,

We hereby confirm your receipt on April 10, 2025, 5:34 PM from Klokradio on 107.0 MHz.

Thank you for your message. It is always nice for us to hear where we can be received.
Klokradio is the local broadcaster of Alblasserdam and Molenlanden in the Alblasserwaard. We started our broadcasts on December 15, 1990 and have existed for 35 years this year.

Because we have a large broadcasting area, we now use three transmitters/antennas.
One antenna is on a flat in Alblasserdam (97.3 MHz) and the other two in Molenaarsgraaf (107.0 and 92.1 MHz).
Attached is a photo of the mast in Molenaarsgraaf. The two horizontally stacked antennas at the top left are for 107 MHz, the yagi opposite for 92.1 MHz. The lower yagi is a receiving antenna for 97.3 MHz, which receives the signal from Alblasserdam and transmits it again on the other two frequencies. In this way we do not have delays when switching between the three frequencies (via RDS in the car). A bit complicated, but that is the disadvantage of a large, elongated service area.
In addition, some pictures that you might like.

We transmit 24 hours a day, but because we work with volunteers, a large part of that time is filled by “the computer”. The broadcast that you heard was one of our live presented programs.

Of course I looked at your website; nice to read what equipment you (have) used.
Thanks again and good luck with the hobby, 73’s.

Kind regards,
Kees (PE1NAC)

QSL Radio60! 5840 kHz

April 15, 2025 / Peter Reuderink / 0 Comments

Last weekend I received Radio60! in good quality on 5840 kHz. Most likely via the transmitter of the Dutch free radio station Contikenzo.
The program was presented by Jürgen who is known as Erden Man in the Free Radio world. He sent me this beautifully designed e-QSL via erdeman(at)gmx.de . Thank you Jürgen!

SSTV QSL WA1QZK Boston

April 14, 2025 / Peter Reuderink / 0 Comments

I’m not so much into HAM radio. Not that I have anything against HAMs – on the contrary – but there is already so much to listen to that I decided not to go there yet. If I’m going to do HAM I want to be able to transmit myself.

That said, I’ve found SSTV always attractive. And particularly when MF conditions aren’t great I don’t mind “sacrificing” one of my DSC receivers scanning 14230 kHz (or another HF SSTV channel). This way I picked up WA1QZK from Boston.

Intercontinental DX is always nice. Problem is that as an SWL (even when registered with VERON) you don’t always have access to email address information in a database like QRZ.com. But Ron, operator of WA1QKZ was so kind to share his email with SWLs as well, so I sent a report… and received the QSL card below. Thank you Ron!

QSL NHK Yamata 9560 kHz

April 12, 2025 / Peter Reuderink / 0 Comments

Pheww.. this one was a little bit tense… Already 5 days ago I got an email prompt (a scan of the card) indicating that my QSL from NHK had arrived in the Netherlands. That’s how the Dutch Postal Service works which is great, but apparently it still took them 5 days to deliver my card. In the mean time I was wondering if they delivered it to the wrong address.

QSL from NHK Japan… might be their final QSL on paper…

Normally I wouldn’t have mind so such, but this was the last chance to get a traditional NHK QSL… Fortunately, today I found it in my mailbox.

I feel a little bit sad about this one, and I’m angry as well. Running a shortwave radio station requires a million dollar budget, but it also requires qualified technical personnel. So sending out a few QSLs per year to people that have a true technical interestest in your station doesn’t seem a bad idea… The “Finance Dudes” seem to have different perspective. Anyway, it is what it is… and this one goes on file. Thank you NHK for all the years that you did grant dedicated listeners a QSL!

QSL RTV Krimpenerwaard 106.6 MHz (and a reflection on local FM radio in the Netherlands)

April 12, 2025 / Peter Reuderink / 0 Comments

It’s April… and I’ve a bit of a feeling this is the Doldrum season for us DX-ers. Winter propagation conditions on mediumwave are behind us. During sunny days the solar panel interference makes DX on MF/HF nearly impossible, and regular SpE conditions on FM are still at least a month away…

But radio is never boring, there is always something to look into. So I thought it might not a be a bad idea to spend some time this year in scanning the FM band for local radio. After all it is almost 50 years after local radio was legalized in The Netherlands.

Following the demise of offshore radio stations like Veronica and Noordzee, the government of The Netherlands allowed some experiments with local radio. And the band between 100 and 108 MHz was empty… except for pirate stations taking the opportunity (but that’s a story for another blog). Between 1984 and 1988 there was an “explosion” of local FM radio stations in The Netherlands. Mind you, in those days internet was not available to the public, and both city councils and entrepreneurs saw this as a must have and an opportunity to connect with a local audience.

QSL email from RTV Krimpenerwaard 106.6 FM, a local FM station in “my backyard”

40 years later it seems that a lot of these stations have merged, just as the municipalities they served merged into larger entities. RTV Krimpenerwaard is a good example. In 1989/1990 I received Radio Vrolek (from Nederlek), Radio Vlistam (from Vlist/Stolwijk) and Radio Bergambacht. Together with Radio Zilverstad from Schoonhoven they merged into RTV Krimpenerwaard… just like these villages (and of course, Schoonhoven is a “stad”) merged into the municipality Krimpenerwaard.

Coverage area of RTV Krimpenerwaard… one of the most beautiful areas in The Netherlands, called “Groene Hart” (Green Heart).

The interesting thing is that it doesn’t seem to stop here. If you browse for the website of RTV Krimpenerwaard you end up on the website of RTV Midden Holland, a cooperation between local radio stations in the region we refer to as “Het Groene Hart”. Including my own home town radio “RPL FM” in Woerden. Definitely professional, up to date… but also more and more regional radio rather than local radio… Should we fear this is a bit like what happened to Indepent Local Radio in the UK, with all these stations being bought by “Smooth” or “Gold” making them commercial regional stations rather than stations serving a local community? Your views?

Below the QSLs I got from VROLEK, VlistAM, and Studio Bergambacht…

QSL KBC Huissen 891 kHz

April 9, 2025 / Peter Reuderink / 2 Comments

From December 1st, 2024, KBC is active on 891 kHz as a LPAM broadcaster from Huissen, The Netherlands. They succeeded Rivierenland Radio.

I heard them with a program with music from the offshore radio era. It was called “Het Zoute Uur” (The Salty Hour). Reception quality was pretty good (SIO 454) despite their 100 Watt and a distance of 72 kms to my QTH. My report was sent via the webform on their site.

KBC also broadcasts on shortwave to Europe, North America and Australia. Details can be found here.

QSL Comodoro Rivadavia Radio 12577 kHz

April 7, 2025 / Peter Reuderink / 0 Comments

I received Comodoro Rivadavia Radio with a DSC test acknowledgement to a vessel with MMSI 311000867 (SYLVIA EARLE, Bahamas). It’s the second time I sent them a report. I heard them earlier in December 2024. They confirmed they were sending a message at the time but my decode of the MMSI of the ship they contacted was incorrect. Despite the ERR check being OK. These things can happen sometimes. This time there was one other DX-er that picked up the same message using YADD decoder, so I was confident I really heard them!

The distance between my QTH and Comodoro Rivadavia is 12890 kilometers… and this is definitely not a DSC station that I hear as often as the ones from Brazil. My other confirmation from Argentina was Buenos Aires Radio.
