Back in October 2009, Wireless Waffle brought to your attention the HF (short-wave) monitoring data produced on a quarterly basis by the ITU. Within these reports were a number of short-wave pirate stations and the original list of stations brought a lot of interest from these stations, both to see who had been 'caught' and to see how close the ITU had gotten to identifying their exact location. Based on the e-mails that were received following the article, it seems like some had hit the nail a little too closely on the head for comfort.

To see how the ITU were getting along, and who had been spotted more recently, a trawl of the montoring reports from January to June 2010 has been conducted and the results presented below. Those stations whose name is shown in CAPITALS were directly identified by the monitoring station concerned. Those in lower case have been identified using the various on-line blogs that report pirate reception.

Please be assured that it is not our intention to name and shame these stations in any way, nor is the Wireless Waffle team opposed to hobby broadcasting (for want of a better word) but we do believe that the stations concerned should be aware that their location may not be as secret as they had hoped.

The question of how accurate these measurements are is a good one. The level of concern that seemed to arise from the previous list suggests that they may be relatively good. However, let's take a real example. There are 10 measurements relating to Mystery Radio. Of these, five different locations are logged. The map below shows the position of these loggings.

mystery radio italy

to catch a pirateThe distance between the closest of all these measurements is around 20 miles (32 km). It is possible that this is the best resolution that some of the monitoring stations can achieve. At this kind of resolution, a ground-based receiver would be unlikely to hear the transmitter. Ground wave signals would not travel this far, and it is the ground wave signal which is required for a person on the ground to be able to 'home in' on the location of a transmitter.

So should pirate radio stations be concerned about being tracked down as a result of the work of the ITU. From the evidence above, it seems that this data alone is probably insufficient to allow a station's location to be identified in one simple move. However, if you are running one of these stations and the location which is shown is more accurate than those for Mystery Radio - and certainly if its within 5 km at which point a man on the ground would be able to track you down - perhaps it's time to up sticks and find a new site!

Whatever happened to...?signal strength

hungarian antennaThere is endless speculation on the internet as to what became of the many pirate radio ships which sailed the seven seas (or the North Sea more specifically) in the bygone era. Wireless Waffle can exclusively reveal the final resting home of one of these infamous nafarious vessels, having been tipped off by a Government source who wishes to remain anonymous. 'Dave Herrish' for want of a better name (and a complete lack of imagination on our part) has informed us that the rigging that adorned the pirate ship 'The Ross Communidel Amigocado' was removed from the hull at a secret military shipyard somewhere on the southern northern Europe coast and transported, piece by piece, to the facilites of Radio Bulgaria where it was re-assembled and used as a mast for their short-wave monitoring station.

Situated between Varna and Dolni Chiflik the antennas are now used as a high gain array for the purposes of intercepting both civil and military radio traffic. But, twice a year, in what must be one of the most ironic celebrations in Europe, the station is opened to the public whereupon bunting and other maritime flags are fastened and festooned to the antennas and small children are allowed to climb up and pretend to be seafaring pirates.

Unbeknownst to many of these children, the Bulgarian phrase for 'I am a pirate', which is 'Лиц ентура дёка ролаян' transliterates as 'lits entura dyohka rolayan' (try saying it out loud), which is often heard being screeched loudly across the countryside accompanied by the ringing of ships bells. Ding dong!

Regulars to the pages of Wireless Waffle will realise that we have an inate (or should that be 'inert') fascination with short wave radio. And nothing is more mysterious and intriguing on short wave than the many spy broadcasts which usually take the form of a string of numbers or letters read out in a mechanical fashion by a pre-recorded male or female voice. A bit like the speaking clock for spooks.

mint spies bingoOne of the most famous spy stations, the Lincolnshire Poacher (which was allegedly broadcast from Cyprus), ceased transmissions in 2008 and it rumour has it that its sister station, Cherry Ripe (latterly broadcast from Australia) also ceased transmissions towards the end of 2009. Which leaves fans of these funky but furtive broadcasts with a big hole in their social calendar (not that such fans had much of a social calendar to begin with).

But all is not lost. Thanks to the Conet project and web designer Kevan Davis fans can now enjoy:

This excellent game will keep you occupied (but not in the same way as the US forces in Iraq) for literally minutes. If you win, it is customary to shout 'Badabingo, green stick in the green hole' though for security reasons we obviously cannot explain why this is so.

What are the chances (Part II)?signal strength
Tuesday 20 October, 2009, 14:29 - Pirate/Clandestine

A previous article on Wireless Waffle talked about the chances of a pirate radio station being caught focussing on VHF FM pirates. A later one focussed on short-wave pirates and discussed which frequencies to avoid in order to minimise getting the authorities' collective danders up.

Over the past 12 months, both Premier Radio (who used 6265 kHz) and Laser Hot Hits (who used 4025 kHz) have had their transmitter sites raided. Bringing together the ethos of the two previous articles, it would make sense that in order for a raid to be worthwhile, even at short-wave, there would have likely been a complaint raised against the station concerned.

So we might, therefore, ask, "Who raised these complaints?" It seems unlikely that major international broadcasters such as the BBC World Service or China Radio International would be at all threatened by pirate operators taking their audience away or causing interference, especially as the frequencies being used by the pirates are not ones being used by an international broadcaster at the time, so there must be another source of complaints.

Across Europe (and indeed the world) there are a series of short-wave (HF) monitoring stations operated by the various national regulatory administrations who produce quarterly reports on their monitoring activities. The purpose of the monitoring and the associated reports is, on the one hand, to check on legitimate users of the HF spectrum, and on the other to identify use which is in contravention to the ITU's rules on spectrum usage. Where an administration identifies contravening transmissions, it can flag these in the reports and, according to the ITU document describing the reports, these will then be forwarded to the administration which is the source of the transmission.

Looking through these reports for the past 12 months (eg from October 2008 to September 2009), there are a number which relate to various short wave pirates. Specifically:

* Where the station was identified in the monitoring report, it is shown in CAPITALS.

Where no name was given, it has been identified and added in by searching through various on-line logs from the date concerned.

In addition to the above there are one or two other unidentified broadcasts on typical pirate frequencies (eg 6447 kHz on 21 August 2009) but there does not seem to be any indication of who they might be (nor do logs help with this).

Clearly there has been a lot of monitoring of Laser Hot Hits going on by various administrations (Laser may be impressed that they were heard in South Korea!) Similarly Mystery Radio and Playback International have also been heavily monitored though the grid references given for their locations seems to vary quite a lot. rambouillet monitoring stationThese stations operate over long periods, usually at weekends but outside these times too, so it is perhaps not surprising that they have been 'caught'. A more interesting question might be why other stations have been monitored. Was it a chance happening by the administration concerned, or are the frequencies they are using of particular interest to that country?

There are many more questions that these logs raise: How many 'complaints' are necessary before action is taken? Are the locations produced sufficiently accurate to find the transmitters or are other methods necessary? Do the various monitoring stations co-operate to improve the accuracy of locations? Is there a competition between stations and administrations to show how 'bad' their neighbours are being (eg UK complaining about France and France complaining about UK). And perhaps, most importantly, how come Mystery and Playback are still on air?!
