Russian pirate station from Belarus active on 3940 kHz

For a long time I've been noticing logs of a Russian station on 3940 kHz named "Music Wave Radio". I never managed to hear this ID but the other day I heard "Russkoe Piratskoe Radio" (Russian Pirate Radio) and e-mail
address  podradio@mail.ru

I sent off a report and the next day came a response from Evgeny Shaden with a QSL and some info: 'Russian Pirate Radio' is indeed the name of the station, "Music Wave Radio" together with "Nostalgic Broadcasts" and "Radio Wagner" {Russian Legion of Foreign Soldiers group left Mali territory recently} are just the titles of the programmes. 

My observation is, that their programmes are generally biased towards patriotism. Their schedule is Saturday and Sunday 1900 "until early in the morning. They give the transmitter power as 20 kW, which would explain the strength, but they will not disclose even the country where the transmitter is located.

UK Propagation Update

 


RSGB

GB2RS News Team | October 3, 2025

Last week was characterised by very unsettled geomagnetic conditions with a Kp index that reached 7.33 on 30 September and was often above 5. 
This is not good for HF propagation!

But what caused this? A high-speed solar wind stream at around 750 kilometres per second, coupled with the Bz component of the Sun’s magnetic field pointing south, led to the disruption. But there didn’t seem to be any particular solar event that triggered the high-speed solar wind stream.

The Russell-McPherron effect is probably to blame. This is a phenomenon where the alignment of the Earth’s and the Sun’s magnetic fields, during the equinoxes around March and September, allows charged particles from the solar wind to more easily penetrate the Earth’s magnetosphere.

This enhanced connection leads to more intense geomagnetic storms and increased aurora activity as the Bz aligns favourably with the Earth’s magnetic field at these times. This may pass as we get further into October.

As a result of the geomagnetic storm, maximum usable frequencies, or MUFs, have often been lower than normal. A quick listen on 28MHz on Wednesday 1 October confirmed the poor conditions. It’s a shame as October is normally a fantastic month for HF DX.

The solar flux index peaked at 187 on 30 September, having been above
170 since 28 September.

Next week NOAA predicts that the solar flux index will remain above 150 to 160 all week. The good news is that geomagnetic conditions are forecast to improve, with a maximum Kp index of 3. If that comes to pass, we can expect HF to be better after a day or two, and we might be able to make the most of the autumnal conditions for DX.

VHF and up:

The current spell of unsettled weather, mainly over northern areas, is typical of the season, but it’s also common to find high pressure passing by in between the deeper lows. In the current pattern, the highs are mainly for the southern half of Britain. This will bring some good Tropo conditions at times for the VHF and UHF bands.

As we head into autumn, these lifts may linger through much of the morning on some days before the temperature rise breaks down any temperature inversion. A good clue is that it’s usually over when the overnight fog clears.

On the other hand, there will probably be some good rain scatter opportunities on the GHz bands as the active lows push fronts across the country, especially in the north. There are signs that we may return to high pressure over the country during the RSGB 2025 Convention weekend from the 10 to 12 October.

We have a meteor shower to play with during the coming week. The Draconids peak on Wednesday 8 October, but the shower stream is spread over the whole of the week.

Lastly, there have been some reasonable auroral events recently so, as usual, keep a watch on the Kp index going over 5 since, as we said earlier, these autumn months are very much favoured for auroral activity.

For EME operators, the Moon’s declination is increasing and goes positive tomorrow, the 6 October, so lengthening Moon windows and increasing peak elevation is the story for the coming week.

Path losses continue to fall as we approach perigee on 8 October. 144MHz sky noise will be low for much of the next seven days.

Radio Prague International, part 1

 This week, Wavescan features Radio Prague International ... a feature you don't want to miss. Special thanks to Ray Robinson and Jeff White for sharing this week's episode.  Part 2 will air next Sunday. 

Vintage QSL card from Radio Prague

Jeff: Last month, while I was attending the HFCC meeting in Prague, Czech Republic, I was able to visit the studios of Radio Prague, which now broadcasts via WRMI shortwave in Okeechobee, Florida.  So now, Ray Robinson in Los Angeles has been digging into the history of this iconic station of the shortwave bands, and this week brings you part 1 of a 2-part series.

Ray: Thanks, Jeff.

I’m sure many shortwave listeners well remember that very distinctive interval signal and sign-on by Radio Prague.  That one was recorded on 6055 kHz in 1973.  When I lived in the UK in the 1970’s and early 80’s, it was certainly a very easy station to pick up.  But, where exactly was it?

Radio Prague International interval signal at YouTube 

I guess I should start by telling you that Prague is the capital city of the Czech Republic, sometimes now referred to as Czechia, a country of about 11 million people right at the heart of Central Europe, who are largely isolated by their very difficult language.


Vintage QSL from Radio Prague


For nearly 75 years, from the end of World War I until 1993, the Czech Republic was united with Slovakia and known jointly as Czechoslovakia.  During the inter-war period, Czechoslovakia was a parliamentary democracy – the only one in Central and Eastern Europe from 1933 onwards.  Nazi Germany progressively invaded from 1938 on, and then in May 1945, Prague was ‘liberated’ by the Red Army.  The Communists formally took power through a coup d'état in 1948, and the country remained the Czechoslovak Socialist Republic under the control of Moscow until 1989.

A period of reform in 1968 known as the ‘Prague Spring’ was famously crushed by the presence of Warsaw Pact tanks in the center of Prague.  Eventually, through what was known as the ‘Velvet Revolution’ in November and December 1989, the communist regime fell, but by 1992, Slovak calls for more autonomy effectively blocked the daily functioning of the federal government.  So, on January 1, 1993, the Czech Republic and Slovakia were peacefully established as two independent states.

So how did radio broadcasting start there?  Well, the first radio program in Czechoslovakia, made up of words and music, was broadcast on October 28th, 1919 from the telegraph station at Prague's Petrin lookout tower.  Regular radio broadcasts were launched on May 18th 1923, by the valve manufacturer, the Elektra Bulb company, a name that was later changed to Tesla.  This made Czechoslovakia only the second country in Europe after the U.K. to have regular radio broadcasting.

These early broadcasts originated from a tent erected at the transmitter site of a communication facility located in a suburban area of Prague called Kbely.  One listener in England reported hearing test broadcasts on shortwave from this site shortly before the regular service on both longwave and medium wave was inaugurated.  Broadcasts at first lasted just one hour per day, and all programs – both news and musical productions – went out live.

January 1924 saw the first broadcasting intended for listeners abroad in English and Esperanto.  Then in the December of that year, the studios moved from Kbely to a Post Office building in Central Prague, and then finally at the end of 1933, they moved again into a building at 12 Vinohradska Street that is still the headquarters of Radio Prague to this day.

Entrance to Vinohradska Street in 1936



In 1926, additional medium wave stations were established in the regional cities of Brno and Bratislava, and others followed in the late 1920s.

In the 1930’s, some European countries had begun regular broadcasting on shortwave – notably England (in 1932), Germany (in 1933) and Soviet Radio in the mid-1930s.  So, with growing political unrest across the continent, a decision was taken in 1934 to commence regular broadcasting from Prague also to foreign audiences outside Czechoslovakia.  Work commenced in 1935 to install antennas and a 30 kW Marconi shortwave transmitter imported from England, in a telegraph building at Podebrody, near Prague.

This unit was designated with the callsign OLR, which over the years has appeared on many of their QSL cards.

The first test broadcast from this new unit was heard on July 24, 1936.

Then, just a few weeks later, at 10am on August 31, 1936, the station began regular programming in five languages, for four hours per day.  By 1937, they had been joined by other regular shortwave broadcasting from Brussels, Copenhagen, Oslo and Vienna.  Over the next few years, the broadcast schedule of Radio Prague increased significantly, and in 1938, two new German transmitters were installed at Podebrody.

But then Czechoslovakia was occupied by the Nazis in 1939.  On March 15 that year, the Nazis stopped all broadcasting from Podebrody on shortwave, decreed that all domestic programming must be in German, and began using the radio for propaganda purposes, even going so far as to ban music by Czech composers.  A few days later, though, they relented a little and allowed the shortwave broadcasts to resume, but only for two hours per day to North America, and only in the Czech language.  All Jewish journalists were forced to leave the station. 

Radio Prague at '50'

Shortwave broadcasts to the country in Czech were made from the BBC in London beginning in September 1939, from Radio Moscow in 1941, and from the Voice of America in Washington beginning in 1942.  But in Czechoslovakia itself, listening to foreign radio was a crime punishable by death.  Then in 1943, the Germans removed shortwave capability from over a million radio sets, effectively preventing the majority of the population from listening to foreign broadcasts.

That same year, international radio monitors noticed the station in Prague was using new call signs.  Instead of, for example, for operation on the 31 meter band, the former Czech callsign OLR3A, the identification had become the German DHE3A.

Over the course of the war, some 14 Czech radio staff members were imprisoned or executed by the Nazis, some for political reasons, and others because they were Jewish.  

But the final German announcement of that era was made early on May 5, 1945.  At 6am, an illicit broadcast from the radio studio in the Czech language helped spark the beginning of the Prague uprising.  Aided by Czech police, the Czech resistance had gained control of the station by barricading themselves in the newsroom, and they were able to inform and inspire the people to rise up against the Nazis.  Fierce battles were fought, many lives were lost, and the Czech Radio building itself was badly damaged.  The city of Prague finally fell to the Red Army four days later on May 9, 1945.


Next week, we’ll continue the story of Radio Prague after the Second World War.

Back to you, Jeff.

Highlights of Solar and Geomagnetic Activity 22 - 28 September 2025

Graphic design by Gayle Van Horn

Solar activity reached R1 (Minor) levels on 23, 24, 26 and 27 Sep and R2 (Moderate) levels on 28 Sep. Region 4217 (S16, L=209, class/area Cko/250 on 22 Sep) produced an M1.1 flare at 23/1034 UTC with an associated Type II sweep with an estimated shock velocity of  835 km/s. On 24 Sep, Region 4224 (S14, L=205, class/area Dso/060 on 26 Sep) produced an M1.0 and an M1.6 flare at 24/0931 UTC and 24/1913 UTC, respectively. An M1.6 flare was observed from behind the E limb at 26/2001 UTC with an associated Type II sweep with an estimated shock velocity of 778 km/s. 

Region 4226 (S11, L=133, class/area on 24 Sep) produced an M1.0/Sf flare and an M1.1/Sf flare at 27/0359 UTC and 27/0423 UTC, respectively. Later on 26 Sep, another activity produced an Earth-directed CMEs. 

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit was at high levels on 22 and 27 Sep with a maximum flux of 1,723 pfu observed at 27/1655 UTC. Normal to moderate levels were observed on 23-26 and 28 Sep. 

Geomagnetic field activity was at quiet to unsettled levels, with an isolated active period midday on 23 Sep. Weak negative polarity CH HSS's dominated the period. Solar wind speeds reached a maximum speed of about 600 km/s midday on 23 Sep. 

Forecast of Solar and Geomagnetic Activity 29 September - 25 October 2025

Solar activity is expected to be at low levels with a likely chance for isolated M-class flares throughout the period. 

No proton events are expected at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit is expected to be at high levels on 05-08 Oct, 13-16 Oct and 21-24 Oct. Normal to moderate levels are expected for the remainder of the outlook period. 

Geomagnetic field activity is expected to be at unsettled to active periods on 29-30 Sep, 11-13 Oct, 19-22 Oct and 25 Oct, all due to negative polarity CH HSS influences. Unsettled to active periods are expected on 03-06 Oct due to positive polarity CH HSS influences. Mostly quiet levels are likely for the remaining days in the outlook period.

Special repeat programming from UBMP on September 28

 


                     Special Encore Broadcast of September's Uncle Bill's Melting Pot Program

Channel 292 will air an encore broadcast of September's UBMP featuring jazz from Russia and Ukraine on September 28, 2025.

Programming will air at 0300 UTC (11pm Eastern US) on 3955 kHz. This is an experiment - although most Europeans are fast asleep, this is supposedly the hour of maximum reach for the frequency, and it may or may not touch parts of the world that don't receive the transmission directly at the usual times. 

We are about to find out. Some past propagation maps for 3955 have shown grey line action at that hour for the east coast of the Americas.

U.K. Propagation Update

 


RSGB
GB2RS News Team | September 26, 2025

Last week was good for HF propagation for a number of reasons. Firstly, we are now entering autumn, which offers better propagation prospects than summer. Secondly, the solar flux index has remained high at up to
184 as of last Thursday, 25 September.

We had a week of near-normal geomagnetic conditions, with a low Kp index, no Earth-directed coronal mass ejections, and a relatively quiet solar wind.

These have all combined to give excellent HF propagation, including openings on the 10m  band using FM and transatlantic 10m contacts being possible in the afternoon.

The maximum useable frequency, or MUF, over a 3,000km path, according to Propquest, has mainly been in excess of 30MHz during daylight hours.

The KQ2H repeater in upstate New York, with an output frequency of 29.620MHz, has been loud at times in the afternoon and is a good indicator of HF propagation. Expect it to get better as we enter October. Other US stations have also been heard on the 10m band using FM, including one in Ohio.

Steve, G0KYA was surprised to hear the GB3XMB 10m beacon on 28.287MHz from Waddington, Lancashire this week. Steve remarked that it is 175 miles to Norfolk as the crow flies. He said that the signal didn’t sound like backscatter, so that’s quite a distance for 10m ground wave.

Other DX worked, according to CDXC, included FP5KE, the St. Pierre and Miquelon DXpedition. The station could heard on everything from Top Band to 10m.

V6D in Micronesia has been working on the 40 and 17m bands using CW.

Other highlights include D2USU in Fiji on the 12m band using FT8, and 9Y49R in Trinidad and Tobago on the 10m band using FM.

Next week, NOAA predicts the solar flux index may fall to be in the 159 to 170 range. Geomagnetic conditions are predicted to be poor tomorrow,
29 September, with a Kp index of 5, and again between the 3 and 5 October, also with a predicted Kp index of 5. Expect decreased MUFs for a few days until the ionosphere recovers.

VHF and up:

The next week or so looks to be typical for autumn. It will be a mix of Atlantic weather systems bringing lows and their fronts which may offer some rain scatter for those on the GHz bands.

The other side of the coin is areas of high pressure or mostly weak ridges, in this case mainly affecting the south and east of the country. 
This is the point where Tropo operators can move in with paths probably favouring the North Sea and Scandinavia up to this weekend and then across to the continent and down to Spain during the coming week.

It is worth remembering that Tropo can exist throughout the 24 hours across water and along coasts like the North Sea and English Channel, although the portion of a path overland can weaken during daytime.

The meteor scatter prospects remain in the random territory, so they are best in the early morning.

Recent activity with geomagnetic disturbances suggests that aurora should continue to be part of the operating list in the coming week. 
Check for a hollow note or warble on HF signals and for a Kp index greater than 5, then consider turning your VHF arrays to the north.

For EME operators, Moon declination reaches its minimum tomorrow, 29 September, so from then on we will see lengthening Moon windows and increasing peak elevation. The Moon’s distance from Earth started to decrease after apogee on Friday, 26 September, meaning path losses are falling. 144MHz Sky noise will be high today, the 28 September, and peaks at around 2800 Kelvin tomorrow, 29 September, before dropping back to low for the rest of the week.

When Weather Bends FM Signals

 


    
          Nick Langan says that tropospheric propagation is the most common “oddity” in FM

By Nick Langan 

Published: September 23, 2025
Nick’s Signal Spot is a new feature in which Nick Langan explores RF signals, propagation, new equipment and related endeavors. 

Maybe you’ve been on the other end of a listener phone call during the summer or fall months.

“What happened to your station? Did it go off the air?”

All is well at your transmitter site. But even within a station’s primary coverage area, a tropospheric band opening can be intense enough to produce interference on the same frequency. 

A Closer Look at Trans World Radio-Bonaire

 
TWR - Bonaire
Thank you to Ray Robinson and Jeff White for sharing this week's programming, featuring Trans World Radio- Bonaire.

Jeff: Some of you may have seen the article in Radio World magazine last month called ‘A Visit to Shine 800 AM’.  It was all about Trans World Radio’s medium wave station on the Dutch Caribbean island of Bonaire, and that caused Ray Robinson to do a bit more digging.  So here he is, with the TWR Bonaire story.

Ray: Thanks, Jeff.  The island of Bonaire lies about 50 miles north of Venezuela and about 850 miles north of the equator.  It’s 24 miles long and three to seven miles wide.  It’s part of the ABC islands, which along with Aruba and Curaçao, used to form the Netherlands Antilles.  But in 201,0 their status was changed, and the Netherlands Antilles, as an entity, was dissolved.  Bonaire, whose population is only about 24,000, became a special municipality within the country of the Netherlands itself.

Trans World Radio started life, of course, as the Voice of Tangier in 1954, from where it broadcast first to Spain, and then to much of Europe and Scandinavia over the following five years.  When the International Zone was placed back under the control of the Moroccan Government in 1959, all international broadcasters were forced to close by the end of that year.  But by May 1960, TWR had resumed broadcasting on shortwave from a new facility in Monte Carlo, and a high-power medium wave transmitter was added four years later.

But in 1963, TWR first expanded to the Western Hemisphere, opening a high-power medium wave station on the island of Bonaire.  The salt flats on the south coast of the island provided the perfect environment for a medium wave station to propagate to South America and the Caribbean.  Their initial transmitter was a 500 kW Continental Electronics unit, which operated at full power on 800 kHz for 35 years.  It was assigned the Dutch callsign PJB.

TWR's Original 500 kW Continental Medium Wave Transmitter

Later, two shortwave transmitters were added – one at 50 kW and one at 250 kW – and they were used mostly to broadcast Spanish, Portuguese and German programming to South America, and English programming to North America with an expanded schedule on Sundays.  Diesel generators were also installed to provide the power necessary to operate all the equipment.


But as time went on, the costs associated with operating and maintaining such high-power tube-type transmitters forced them to cutback.  In the late 1980’s, the power output from the 250 kW shortwave transmitter was reduced to 100 kW, and then in 1993, all shortwave broadcasting from TWR Bonaire ended.  In 1998, the 500 kW medium wave unit was replaced with a 100 kW one, a Nautel NX100, and the diesel generators were taken out of service.  The station still had twice the power on medium wave of any station in North America, but it was nothing like the flame thrower it had once been.

 But the following year, in 1999, a new medium wave antenna was designed by Tom King of Kintronics Labs in Bluff City, Tennessee, who also engineered and installed it.  The design utilizes four 478’ tall active towers at the four corners of a rectangle, which through selective termination can be used to create three different directional antenna patterns – one for the Caribbean, Venezuela and Colombia, one with a beam to the north west for Cuba, and a third with a beam to the south east that reaches much further down into the Amazonia region of northern Brazil.  By using this new antenna, TWR aimed to maximize the impact of the 100 kW transmitter.

They had many loyal listeners, but by the early 20-teens, it was apparent there was still a need for higher power.  The station said they had a lot of people in Cuba asking if they could increase the power again to cover the whole island with Christian programming on medium wave.  So, they launched a new project, and over a period of about four years, managed to raise almost $4 million for the purchase and operation of a new high-power solid-state transmitter.


Coverage Patters of the Three Antenna Beams


But, there were no 500 kW transmitters now being manufactured.  One option they had was to combine two 250 kW units to achieve the same output power as the old Continental.  But instead, they found they could get close to that level by selecting a Nautel 400 kW unit, the NX400, which could be assembled from ‘off-the-shelf’ parts for much less cost than two 250 kW units.  It uses MDCL – modulation-dependent carrier level – which enables it to achieve greater than 90% efficiency, and thus it is also quite economical to operate.

The antenna was upgraded for the higher power with new tuning houses at the base of each mast.  The new NX400 transmitter was shipped from Nautel’s facility in Nova Scotia, Canada in eight crates, and it was received in Bonaire in December 2017.  It was installed in the space occupied until 1998 by the old 500 kW Continental, and a dedication ceremony was held on January 30th 2018.  As with all Nautel solid-state transmitters, the NX400 has what the manufacturer calls a “10% overhead”, which means TWR can and does put out closer to 440 kW from Bonaire.  Combined with the more effective antenna design, this means the station now actually sounds stronger than it did with the old 500 kW transmitter decades ago.

The current technology also allows the station to operate with a smaller staff.  Back in the 60’s and 70’s, TWR had close to 100 people doing live radio out of Bonaire, but today’s operation is much more labour-efficient.  Both the transmitter and the antenna switching equipment can be monitored remotely, and program producers no longer need to leave the target audiences they are serving.

Mark Persons of Radio World visited TWR Bonaire recently, and he wrote in last month’s issue that the station “is silent during the day but comes alive at night.  From 7:30 to 8 p.m., they broadcast in English to the Caribbean islands, then the pattern is switched to the northwest from 8 p.m. to midnight, when Spanish programs are sent to Cuba via skywave bouncing off the ionosphere.  And yes, they do put a reliable signal into Cuba, some 900 miles away.  In the mornings, “The antenna is on the southeast pattern from 4:30 to 6 a.m. when Portuguese is beamed as far as 1,200 miles into Latin America, again by ionospheric reflection.  Then from 6 to 7:30 a.m., the station is nondirectional with Spanish programs to the Caribbean, Colombia and Venezuela.  Listeners know when to tune in.”

Lauren Libby, the former President of Trans World Radio before his debilitating stroke last year, said the station’s enhanced power and coverage not only helps spread Christian programming to a wide area, but is also useful in other ways.  He said:  “When you get into an emergency situation, there’s nothing that beats medium-wave.  For instance, when the hurricanes came across the Upper Antilles we were on the air every night with weather, encouraging those affected and talking to people throughout the region live on the air.  The Dutch government says whenever there’s a disaster, just tune to 800 AM because that’s where you can get information.  That was one of the reasons that we did what we did — to allow the Dutch government to be able to talk to their territories in the Caribbean, all the way from Saba in the north to Aruba next door.  You need this kind of power if you’re going to do that.”

Here in North America, unless you happen to be close to CKLW in Windsor, Ontario or are unable to null them out, those late evening hours are probably the best time to try to log the 800 kHz signal.  Bonaire is on Atlantic Standard Time all year round (currently the same as Eastern Daylight Time), so that corresponds to midnight to 0400 UTC.  Listen out for their ID in Spanish – Radio Trans Mundial.
