Dutch MW pirates: a history and how to hear them

The Dutch MW pirates are a well-known phenomenon. However, knowledge of these stations has traditionally been almost non-existent among most DXers and there is little publicity about them other than on blogs like ours. To remedy this, we'll take a look at the MW pirate scene and provide you with essential details to consider when DXing these underground stations from the Netherlands.

A brief history

The first Dutch pirate transmitter was built around 1915. As far as we know, there were only a few pirates before World War II, but at the end of the war many of the American and French army transmitters were put into circulation all over the country, paving the way for many people to start up their own stations. At this time the pirates provided the audience with Dutch folk music, and this format has mainly been used ever since as the legal stations never have offered this kind of service.

Jumping three decades to the 70s, a new kind of pirate popped up on the 227 metre band (1300-1330 kHz), usually called "international broadcasters" as they had broadcasts in English, dedicated not only to a local audience, but also to DXers all over Europe.

For several years the activity on 227 was intense and many of the stations became very popular. Among those were Radio Corallfisher, Radio Hawaii, Radio Tom Cat and Radio Nolan. The latter told us he could get around 100 letters for only a one-hour broadcast, a figure that most pirates of today can merely dream of.




At the start of the 1980s legal broadcast stations began occupying some of the 227 metre frequencies, leaving no space for the MW pirates, and consequently one by one they left the airwaves.




A few years later, however, new frequencies were found in the MW band and the international pirate scene was revived, mainly with broadcasts on 1508 kHz. Radio Orang Utan was the very first station to use the frequency. That was in March 1985, and it turned out to be a very good and clear channel. Just a few months later, several other international pirates also could be heard there. One of the most active stations besides Radio Orang Utan was Radio Torenvalk, who also used 1094 kHz for their regular transmissions.




For some reason these frequencies were abandoned after only two years and those stations who were left went back to the 186 metre band and some moved to shortwave. 

In April 1992 new morse signal stations from Scheveningen in northern Holland began broadcasting on 1611 and 1615 kHz, making reception of Dutch pirates in the frequency range 1610-1620 kHz very difficult. Only a handful of stations continued to operate in this part of the band. However, all was not lost as most of the previous occupants moved down band just a little and could be heard mostly between 1604 and 1610 kHz. A few stations also revived 1508 kHz - the likes of Radio Perlee, Radio Pirana and Radio Barones, who could all be heard with regular international broadcasts.

The different types of Dutch MW pirate
In terms of Dutch pirates on mediumwave we are usually referring to stations operating on the 186 metre band, that is the range from 1610 to 1640 kHz. There are some pirates who operate lower down the MW band - 1575, 1548, 1539, 1512, 1494 etc, but these are often low-power daytime locals and can hardly be heard from outside their own area. In the last few years some of the Dutch pirates have tried out going a little higher than 186 metres, experimenting on frequencies up to 1700 kHz  - Radio Digitaal can often be heard straying this high up the band - but, as a rule, you don't hear many stations this high.

There are a large number of pirates in the Netherlands. Many of them broadcast on the FM band, some with huge teams of people running up to 30kw of power. Over the past decade MW activity has gradually increased due to the overcrowded state of the FM band.

Basically, there are three types of Dutch pirate operator. First, we have the already mentioned international stations, who usually have a programme format similar to the SW pirates (pop/rock music, jingles and announcements). Names like Barones, Ros Am, Casablanca and Batavier fit firmly into this area.

In the second category we have the so-called zender amateurs, who provide a service of Dutch folk music. They also often make qso contacts, in which two or more stations give signal strength and modulation quality reports to each other. A QSO starts with two stations initially and often more stations come along with it, which sometimes can develop to involve anything up to seven or even more pirates. Names like Monte Carlo, Toulouse and Noordzee figure here.

Last, we have stations
 whose main interest is to play music to a local audience only. There are also mixtures of these categories - it’s rather common that some of the pirates make international broadcasts as well as making Dutch folk music programmes and QSOing.

 
When to listen
The Dutch pirates can be heard daily all year round. The best time to listen out for them overseas is from around 1700 UTC to midnight, and sometimes even later. On weekends activity increases dramatically. The few international broadcasters can mostly be heard on weekend nights, although other days and times are used too.

Some stations have regular broadcast times. You can hear Marianne every Tuesday evening on 1620 kHz, for example. Thursday mornings on 1636 is when you can hear Torpedojager, while early Sunday mornings are a great time to catch Noordster on 1620, and Witte Tornado is active on occasional Sundays on 1647 kHz from 1600 UTC.

While some stations might not have regularly transmission times, many do have specific frequencies. While this helps to establish an audience, another reason for staying put is because of the antennas used by many of the pirates. Their coil designs have a very narrow bandwidth, which means the transmitter will give full power and work at its best only on the frequency for which the antenna has been designed. A change in channel can lead to a big decline in the effectiveness of the antenna.


Here are some stations to listen out for use who have a regular spot on the band:

Atlantic 1611
Blauwe Koe 1615
Bluebird 1629
Casablanca 1640

Marianne 1620 (Tuesday evening)
Mi Amigo 1636
Moby Dick 1652 (Saturday evening)
Moonbreaker 1647
Noordster 1620 
Pandora 1625 
Pereboom 1648
Philadelphia 1611

Ros Am 1620
Schaduwjager 1620 
Torpedojager 1636 (Thursday morning)
Utopia 1611
Witte Raaf 1655
Witte Tornado 1647 



When DXing the Dutch pirates, listen for tune-up whistles and strong open carriers all over the band. Many stations can be heard this way and can often lead to some lengthy QSOs. Now and again you will hear announcements between the Dutch folk music records, so listen for the station identifications. A phone number, usually for text messages or WhatsApp contacts might be given out, and sometimes (although it is becoming more rare) an email address. Some stations might have an email address but no longer announce it as they prefer not to be contacted in this way. They prefer instant contact which does not involve time-consuming responses to emails and sending out qsl cards.

It’s not much use telephoning a Dutch pirate unless you can give a verbal Dutch report and be understood. You might have just heard an identification and location given in perfect English, but this is probably the only English the station operator knows, having repeated it for many years. A fair amount of the MW pirates do speak fluent English, but many do not.

When a station has been on the air for a while with a music programme and announces a close-down, this is the time to listen very carefully. Check all frequencies as more often than not one, two or possibly three stations will be waiting to give him a report. 

 
Why it can be difficult
Some stations you will hear have a splendid modulation quality, but a number of the pirates sometimes have a distorted modulation which often makes it impossible to decipher the speech. One way to help matters is to use amplified audio and a bandwidth filter connected between your receiver and loudspeaker or headphones. The improvement is often dramatic.

Another problem with listening to the Dutch MW pirates can be drifting. With DDS transmitters and high-quality Greek-built transmitters, this is now far less frequent than it used to be, although unstable carriers can still be noted. A few of the pirates use very old transmitters which continue to move around even when they’ve been on the air for some time. The BC191 transmitter which was used during wartime is renowned for such drifting but can still be found in some pirate studios:





There are quite a few difficulties when it comes to reporting the Dutch MW pirates. Although some of them can be found in the pirate radio chatroom and can be contacted immediately with a reception report, others may not be interested at all in hearing from you. Most of these stations belong to the third category (local low-power operators) and if you do hear one of them, usually the only way to contact them is to rely on the goodwill of a pirate in the neighbourhood and ask him to forward your report to the station in question.

In you do make contact, be it via email, text message or WhatsApp you can include a SINPO rating in your report, but beware it will not be understood by all of the pirates. Therefore, you should also describe the reception in words. Primarily they are interested in signal strength and modulation quality, which simply can be described as any of poor, fair, good, very good etc. Then you can go on describing any type of interference and anything else that might be of interest to the station.

Since many stations play Dutch folk music and QSO in Dutch, it might be difficult for you to get appropriate programme details. To spare this trouble, you can enclose an MP3 recording of the reception, which is often highly appreciated by the pirates. But if you do send an audio report, also record some other stations you have heard as this is likely to interest him as much as his own signal.

If you receive a response and a QSL you should always send the station a note of thanks for the reply. This may sound unnecessary, but it is self-evident that politeness is much appreciated by the pirates. It also helps the next DXer's report gets a reply as well.

Radio equipment and antennas
Any radio receiver that covers the required range can be used to DX the Dutch MW pirates. For the best results, however, a communications receiver that has good selectivity and sensitivity and a digital frequency readout is what you want. The best antenna to use for Dutch pirate DXing is a loop, either indoor or outdoor.

My very first receiver was a Russian-built Vega Selena 215, and I have happy memories in the early 1990s listening to the likes of Radio Barones, Nooitgedacht, Pelikaan and Pedro. There was no digital display, and tuning to certain frequencies was all rather hit and miss. I've heard the strongest Dutch pirates on all sorts of radios, some very inexpensive. Reception is largely down to the antenna. Get that right and you're guaranteed to hear plenty of stations.



After the Vega, I remember a Sangean ATS803A, a Sony ICF2001D, and a Lowe HF150. I still have all these, but now mainly use a Lowe HF225 and a Kenwood R5000.

When I first started out I built my own little box loop antenna. High-tech it was not - in fact, it was a very crude design. However, it worked well and pulled in plenty of Dutch MW pirates, especially on family holidays in Norfolk on the English east coast. I later upgraded to an octagon design, and used it with an amplifier, which again gave very good results.



These days I have a couple of portable loops for holidays, but mainly use a Wellbrook loop antenna pointing straight towards the Netherlands, and it really is very good. I have had a few of their designs over the years, but this is the one I've currently got installed.






Most residential areas have plenty of local interference, and I get my fair share here, too. So, in order to combat this and get noise-free reception of the pirates, I use a noise cancelling unit. This requires two antennas (the loop and, in my case, a random length of wire) and uses one against the other to null out the offending signals. I find it an essential piece of kit.



I hope this information has been useful and provided an insight into a sometimes confusing part of the radio spectrum. 
If there is anything I've missed or something specific you would like to know about the Dutch MW pirates, I'll always do my best to help. Just drop me an email at mwpiratefan@gmail.com.

Solar activity and a trip to Japan

It's wet, windy and cold in the UK and it's been like that all week. Just as well there has been plenty on the radio to keep me happy, despite some challenging listening conditions. It's time to update the logbook and, as ever, the listening equipment here is old-school with the Lowe HF-225 and Wellbrook loop antenna.

    Observations

    • This morning I received a propagation report from my pal Nige that suggested conditions would be abysmal for listening today, so my expectations for an afternoon and evening of entertainment on 1.6 MHz were duly tempered! So when I switched on the radio at just after 3.30pm local time here in the UK I was very surprised to hear a strong signal coming in on 1611 kHz. It belonged to Twentana, who was testing. A few moments later I heard a similarly strong signal just 9 kHz higher on 1620 where Zwarte Boekanier was putting out a request for reception reports. And then there was Arona on 1636 kHz and then Utopia with a report for Twentana. Then things turned. 
    • I could see from the various online SDRs and WhatsApp groups that Concorde was transmitting on 1611 kHz and Eigen Risico on 1636 - usually I would have no problem hearing these stations given all the others I’d already received. So, propagation conditions were certainly disturbed owing to huge solar activity resulting in the Northern Lights having been widely seen across the UK the previous evening. While the signals I couldn’t hear did later put in an appearance, they were weaker than usual and the stronger stations were suffering from much more fading than usual, and short rapid fades where those using wire antennas usually suffer from long, deep fades, sometimes so deep that the signal would nearly disappear.
    • The best catch of the day came on 1548 kHz, where Bizon was testing from the Veluwe region with just 10 watts of power. To hear this low-power signal given good conditions would be impressive, but considering propagation was massively disturbed and far from optimal, this was nigh on incredible, especially as the sinpo was around 33333 with some co-channel interference and fading the only real listening issues.

      • The Sunday morning qso today was a bit of a quiet one - just the four stations gracing the airwaves to give their reports once Noordster had closed down from his weekly breakfast show. Among those stations, however, was a new one for me in the shape of Zilervos from Friesland. His signal might have been only weak here, but I could hear him and that’s what counts! Good also to catch Zwarte Bouvier during the early evening - it’s been a while since I heard him.

        • Some interesting in-band catches from the Netherlands today, plus a new name for me. Zilvermeeuw (Herring Gull in English) was coming in pretty well at just before 4.30pm local time in the afternoon, and using 1575 kHz. And then, just a few minutes later there was activity just a nudge down the band on 1548 kHz when Matrix switched on their transmitter for a test. The signal was good, peaking up to a sinpo of 45444, and it will be no surprise to see more of these in-band frequencies used for international transmissions with British legal stations closing down their AM operations, the most recent being Desi Radio on 1602 kHz.

        • When station operators turn on their transmitter, they can never be certain where the signal will end up. You could be running one watt of power, 100 watts or 1kw-plus, but there is an uncertainty about radio, which of course, is part of the fun. But when Ros Am signed on today, one thing is for sure - he didn't expect that signal would be heard in Japan. Not on an online SDR, but by a well-known and respected DXer on his very own receiver and antenna, at a distance of approximately 9,000 kilometres. And here is the reception report that was sent to Ros Am, which has been verified and made the station operator very happy indeed!
