Highlights of Solar and Geomagnetic Activity

20 - 26 July 2026

Solar activity was at low to R1 (Minor) levels this period. A total

of 54 C-class and 6 R1 (Minor) events were observed. The largest,

and most complex spot group, was Region 4493 (N06, L=158, class/area

Eki/440 on 23 Jul). This region produced a total of 42 C-class and 5

M-class events, the largest an M3.6 at 22/0635 UTC. A 200 sfu 10 cm

Burst was associated with this event. Region 4494 (S04, L=088,

class/area Dac/120 on 26 Jul) produced the other R1 (Minor) event,

an M3.2 at 26/1528 UTC. Associated with this event was a Type II

Sweep with an estimated shock velocity of 1,057 km/s. No other

significant activity was observed. 

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit was at

high levels on 20 and 26 Jul with the high value of 1,300 pfu

observed at 20/1645 UTC. 

Geomagnetic field activity was at quiet to G1 (Minor) levels. Quiet

levels were observed on 20 Jul. Levels increased to unsettled to

active on 21 Jul to early on 24 Jul, with isolated G1 (Minor) levels

observed late on 23 Jul. This activity was due to effects from a

negative polarity CH HSS. Quiet conditions were observed most of 24

Jul and 25-26 Jul. 

Forecast of Solar and Geomagnetic Activity

27 July - 22 August 2026

Solar activity is expected to be at mostly low levels with a chance

for moderate R1 (Minor) levels throughout the outlook period. 

No proton events are expected at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit is

expected to reach high levels on 27 Jul, 02-03 Aug, 06-09 Aug, 12-16

Aug, and 22 Aug. The remainder of the outlook period is expected to

be at normal to moderate levels. 

Geomagnetic field activity is expected to be at unsettled to active

levels on 27-28 Jul due to potential weak CME effects. Unsettled to

active levels are expected on 29-31 Jul, 04-07 Aug, 11-12 Aug, and

17-20 Aug with isolated G1 (Minor) levels possible on 19 Aug. This

level of activity is due to recurrent CH HSS effects. Mostly quiet

levels are expected for the remainder of the outlook period.

99 Years of Indian Broadcasting / AIR / Akashvani, part 2

 

Thank you to the Wavescan staff for Part 2 on the history of AIR/Akashvani

Part 2 – 1936-Today

Jeff:  Today, Ray Robinson continues our feature on the 99th anniversary of broadcasting in India, and the 90th anniversary of Akashvani in particular, with grateful thanks to the Indian DX Club International and their Asian DX Review.

Ray:  Thanks, Jeff.  So the Indian Broadcasting Company began broadcasting 99 years ago on July 23, 1927, initially with a single station in Bombay.  Just over a month later, a second station was added in Calcutta.  But the company faced financial difficulties, and less than three years after its launch, in March 1930, it collapsed and entered liquidation.  A few weeks later, on April 1, 1930, the Government stepped in and relaunched the stations as the Indian State Broadcasting Service.  And that service was duly renamed ‘All India Radio’ on June 8, 1936 – 90 years ago.

Walter Kaufman was a Jewish refugee from Czechoslovakia.  He was an accomplished violinist who fled Europe to avoid being captured by Hitler’s Gestapo, and he lived in Bombay until after the war, when he returned to his homeland.  In 1936, he composed the signature tune for All India Radio, which became the wake-up alarm for a nation.

The late 1930’s transformed broadcasting in India.  A station was opened in New Delhi.  News bulletins became a regular feature.  External broadcasts began reaching audiences beyond India's borders.  Engineers worked tirelessly to expand transmitter networks and improve reception.

Then came the Second World War.  The conflict dramatically increased the importance of radio.  Governments around the world relied upon broadcasting to communicate information, maintain morale and reach distant populations.  India was no exception.

On October 1, 1939, the External Service began with a broadcast in Pashto, intended to counter German radio propaganda targeted to Afghanistan and the North-West Frontier province.  Other broadcasts in Dari, Persian and Arabic were soon added for regions that were then British protectorates.

AIR expanded its news operations and foreign-language services.  Broadcasting became an essential instrument of communication.  In February 1943, a new ‘Broadcasting House’ was opened at Parliament Street in New Delhi, and by the end of the war, radio had become firmly established in public life.

Every institution has moments that define its legacy.  For All India Radio, one such moment arrived at midnight on August 15, 1947 – the date of Indian independence from Great Britain.  Across the country, listeners gathered around radio receivers.  

Some listened in homes.  Others listened in public spaces.  Many remained awake through the night.  Through the microphones of All India Radio, India heard the voices that announced the birth of an independent nation.

The airwaves carried speeches, celebrations and history itself.  In that moment, radio was not merely reporting events.  It was helping create a shared national experience.  The country was listening together.

And yet, on that momentous occasion of Independence, AIR's reach remained surprisingly limited.  The network operated only a handful of stations and transmitters.  Much of rural India remained beyond effective coverage.  The decades that followed changed that dramatically.  New transmitters rose across the country, and power levels were increased.  Coverage was expanded into previously unreachable regions.  Engineers transported equipment through mountains, forests and deserts to bring broadcasting to remote communities.

The results were remarkable.  What had once covered only a small fraction of India gradually evolved into a network reaching nearly the entire population.  For millions, radio became the most accessible source of information, education and entertainment.

If the 1930’s and 1940’s were about building infrastructure, the 1950’s, 1960’s and 1970’s became the golden age of programming.  Radio entered Indian homes in a way no other medium had before.  The National Programme of Music introduced listeners to the finest classical performers in the country.  Farm broadcasts delivered practical information to rural communities.  Educational programs supported literacy and development.  Children's programs became beloved family traditions.

In 1956, All India Radio was officially renamed Akashvani, which means ‘Voice from the Sky’ in Sanskrit.  

But the arrival of Radio Ceylon had challenged All India Radio’s dominance in entertainment broadcasting.  So in response, the Vividh Bharati channel was launched on October 3, 1957, and it transformed Indian radio.  Film songs, light entertainment, listener requests and celebrity presentations captured the imagination of millions.  For an entire generation, the sound of radio became inseparable from daily life.  The radio accompanied breakfast.  It played during work.  It entertained families after dinner.  It became a member of the household.

 Audio Clip - Vividh Bharati, Simla available at: https://www.podomatic.com/podcasts/wavescan

One of Akashvani's greatest achievements often receives less attention than it deserves.  It preserved much of Indian culture for posterity.  Before digital recording, before streaming platforms and before online archives, AIR was documenting the nation's cultural heritage.  Legendary musicians, poets, dramatists and scholars performed in front of AIR microphones.  Rare traditions were recorded, and regional languages found representation.  Folk music from remote villages was preserved for future generations.  The archives that emerged over decades became one of the most valuable collections of Indian cultural history ever assembled.  Without Akashvani, much of that heritage might have been lost forever.

No institution survives for ninety years without facing challenges.  AIR was often criticized for excessive bureaucracy and slow decision-making.  Questions about editorial independence surfaced from time to time.  Television created a new competitor for audience attention.

Later came private FM stations with energetic presenters and highly localized content.  Then the internet changed everything.  For many traditional broadcasters around the world, the digital revolution proved disruptive.  Akashvani faced the same challenge.  Could a public broadcaster built in the age of valves and transmitters remain relevant in the age of smartphones and streaming?  The answer required reinvention.

Today's Akashvani bears little resemblance technologically to the network inaugurated in 1936.  There are now 420 stations nationwide, covering 92% of India’s geographic area and over 99% of its population.  Programming is available in 23 languages and 179 regional dialects.  FM broadcasting began on July 23, 1977 in Madras, now known as Chennai, and DRM technology has improved audio quality still further throughout the country.  Online streaming allows global access.  Mobile applications bring programs to younger audiences.  Podcasts extend the reach of traditional radio content.  Social media platforms create new forms of engagement.  Yet despite these transformations, the essential mission remains unchanged – to inform, to educate, to entertain, and above all, to connect.

Of course, what listeners outside India remember is All India Radio’s General Overseas Service, which is heard around the world.

 Audio Clip - All India Radio General Overseas Service available  https://www.podomatic.com/podcasts/wavescan

Even though the network’s name was officially changed to Akashvani back in 1956, it was still frequently referred to on air both as AIR and All India Radio right up until 2023.  All India Radio was a term originally coined by Lionel Fielden in 1936, and so for some, it had connotations of India’s colonial past.  Thus, on May 3, 2023, an order was issued by the Indian government that the network should henceforth solely refer to itself as Akashvani.  Even on that date, the English morning news bulletin -- broadcast at 8.15am -- carried the ‘All India Radio’ name in its introduction.  But by the afternoon news bulletin, broadcast at 4.05pm, the announcer had switched to Akashvani.

 Audio Clip - It's Akashvani - India's public radio service is no longer called 'All India Radio' available at  https://www.podomatic.com/podcasts/wavescan

The story of Akashvani is one that began with engineers who built transmitters in difficult conditions, artists who enriched the airwaves, announcers whose voices became household companions, and listeners who welcomed radio into their lives. 

From the inauguration of the Indian Broadcasting Company in 1927 to today's digital broadcasts reaching audiences around the world, nearly a century has passed.  Yet the fundamental purpose of broadcasting remains the same:  to bring people together through sound.  Long before India became digitally connected, Akashvani had already created something equally remarkable — a nation listening together.  So, as India celebrates ninety years of All India Radio and honors the enduring legacy of Akashvani, we are reminded that broadcasting is not merely about transmitters, frequencies or technology.  It is about people.  It is about stories.  

And it is about a voice that, for generations, helped India hear itself.

Back to you, Jeff.

Part 1 – 1920-1936

Jeff: Last month, on June 8, Akashvani in India celebrated 90 years since the official renaming of the Indian Broadcasting Company as ‘All India Radio’.  On Thursday this week, July 23, it will be 99 years since the IBC, the predecessor of AIR , was first inaugurated in Bombay.  So today, Ray Robinson takes a look back at the circumstances surrounding that historic event.

Ray: Thanks, Jeff.  And I must start by acknowledging that much of the material for today’s feature comes from an excellent article written by Sandipan Basu Mallick, VU3JXD, which was published in last month’s journal of the Indian DX Club International, the ‘Asian DX Review’.

The story of broadcasting in India began with a handful of curious men, homemade transmitters, experimental aerials and an almost magical belief that voices could travel through the sky.  Imagine Bombay in 1920.  The city was alive with the energy of a rapidly changing world.  Electricity was becoming more common.  Motorcars were appearing on the streets.  Wireless communication had begun transforming shipping and military operations across the globe.

Among those fascinated by this new technology was a young entrepreneur named Gianchand Motwane.  Motwane was not merely a businessman.  He was an experimenter, one of those restless minds who saw possibilities where others saw impossibilities.  In 1920, he conducted what is widely regarded as the first radio transmission in India.  It was modest by modern standards — a low-powered experimental broadcast — but it demonstrated something extraordinary:  voices and sounds could travel without wires.  The future had arrived.  The transmission lasted only a short time, but it marked the beginning of Indian broadcasting history.

Over the next few years, wireless enthusiasts began gathering in Bombay, Calcutta and Madras.  They were part scientists, part hobbyists and part adventurers.  They assembled receivers from imported parts, strung aerial wires across rooftops and spent evenings listening to distant signals fading in and out of the static.

In August 1921, a collaborative experiment between The Times of India and the Posts and Telegraph Department transmitted a program from Bombay. Remarkably, the signal was heard more than a hundred miles away in Poona. For those who experienced it, the achievement seemed almost miraculous. The possibilities of radio had become impossible to ignore.

The early 1920’s were the years of the radio clubs.  The Radio Club of Bombay began regular broadcasts in 1923.  In Calcutta, the Radio Club of Bengal followed with its own transmissions.  In Madras, enthusiasts established the Madras Presidency Radio Club, which soon became one of the most active centers of broadcasting experimentation in India.

These pioneers worked with limited resources and often improvised equipment.  Yet they possessed something more valuable than money:  enthusiasm.

 

In Calcutta, demonstration broadcasts conducted with Marconi equipment amazed listeners.  Music concerts and speeches travelled through the air to audiences miles away.  Newspapers reported these experiments with excitement.  Radio was still a novelty, but it was rapidly becoming a sensation.

In Madras, broadcasting owed much to the efforts of dedicated individuals such as C. V. Krishnaswamy Chettiar, who assembled transmitters from imported components and helped create a functioning radio service.  Programs included music, talks and educational content.  Loudspeakers were installed in public places so that even people without receivers could listen.

For many Indians, this was their first encounter with broadcasting.  Listening itself became a social event.  Families gathered around receivers.  Friends invited neighbors to hear distant voices.  Public demonstrations attracted curious crowds. Radio was not yet a household appliance.  It was an event.  Few realized that these modest clubs were laying the foundations for one of the world's largest broadcasting networks.

The defining moment arrived on 23 July 1927.  The Indian Broadcasting Company had been established to create a professional broadcasting service for India.  Its first station was ready in Bombay.

Newspapers across the region reported the event.  One report published in The Singapore Free Press and Mercantile Advertiser described the inauguration of the "Bombay Beam Radio Station" and highlighted the significance of this technological achievement.  Lord and Lady Irwin, the Viceroy and Vicereine of India, travelled to Bombay to formally inaugurate the station.  The ceremony attracted dignitaries, businessmen and wireless enthusiasts.  There was a sense that something historic was unfolding.

Speaking at the event, Lord Irwin reflected on the power of broadcasting to connect people separated by distance.  He noted that radio could provide companionship and information to those living in remote locations.  Looking back nearly a century later, his words seem remarkably prophetic.  The Bombay station began regular broadcasting on that day.  Just over a month later, Calcutta received its own station. For the first time, organized broadcasting had truly arrived in India.

Yet success was far from guaranteed.  Running a broadcasting service in India during the 1920’s was expensive.  Receivers were costly.  The audience was still relatively small.  Revenue struggled to keep pace with expenditure.  The Indian Broadcasting Company faced mounting financial difficulties.

In March 1930, barely three years after its triumphant launch, the company collapsed and entered liquidation.  The future of broadcasting in India suddenly appeared uncertain.  Had the story ended there, radio in India might have developed very differently.  Fortunately, public support for broadcasting had already grown strong enough to prevent its disappearance.  Political leaders, listeners and public figures recognized its potential importance.  So, the Government stepped in.

On 1 April 1930, broadcasting resumed under government management as the Indian State Broadcasting Service.  The patient had been saved.

Every great institution eventually encounters an individual who shapes its destiny. For Indian broadcasting, that person was Lionel Fielden.  A senior BBC producer, Fielden arrived in India in 1935 as the first Controller of Broadcasting.  He inherited a service that was financially fragile, organizationally uncertain and geographically limited.  Yet he also recognized its immense potential.  Fielden believed radio should not be merely an urban entertainment service catering to elites.  It had to speak to India in all of its diversity.  It had to reach villages as well as cities.  It had to represent Indian culture rather than simply imitate British broadcasting. 

Under his leadership, expansion accelerated.  New stations were planned.  News services were improved.  Programming became more diversified.  And most importantly, the service acquired a new identity.

On June 8, 1936, the Indian State Broadcasting Service was officially renamed All India Radio.  The name captured an ambitious vision:  a broadcasting service for the entire nation.  Few could have imagined how profoundly that vision would shape India's future.

And we’ll pick up the story again next week, with the looming War years, Independence in 1947, and beyond.

The Mystery of Radio Curom

 Thank you to the Wavescan staff for the nostalgic story from Curaçao Island

Whatever Happened to Radio Curom on Curaçao Island in the Caribbean?

Jeff: Last September, Ray Robinson presented a feature about shortwave and medium wave broadcasting on and from the Dutch island of Bonaire in the Caribbean.  Bonaire is well-known as the home of the high-powered stations of both Trans World Radio and the former Radio Netherlands relay site.  But Bonaire is just one of three islands that make up what used to be called the Netherlands Antilles, or the ‘ABC’ islands of Aruba, Bonaire and Curaçao.  What is often not remembered these days is that Curaçao also has a history of broadcasting on shortwave, so here’s Ray again to tell us about that.

Ray: Thanks, Jeff.  Curaçao is located about 40 miles off the coast of Venezuela in the central Caribbean, and is approximately 44 miles long, and 10 miles wide.  The highest point of elevation on the island is Mt. Christophelberg at 1220 ft high.  There are no rivers, and only seasonal lakes.

The island’s history began with the arrival of Amerindians from South America around 2500 BC, and the first European colony was established by the Spanish in 1499.  The Dutch took over in 1634, and during the Second World War when the Netherlands was under Nazi occupation, American and British forces provided administration temporarily as a protective measure until the war was over, when the island was returned to the Netherlands.  The American troops also built a military airport.

In 2010, Curaçao officially became its own country, a constituent island country within the Kingdom of the Netherlands.  It is autonomous, although The Hague retains responsibility for defense and foreign policy.  The current population is about 160,000, who primarily speak Papiamentu – the creole language of the ABC islands that’s largely based on Portuguese as spoken in the 15th and 16th centuries.  But most of the population is also fluent in the official language of Dutch, and some also speak Spanish and/or English.  Curaçao is the largest of the ABC islands, both in terms of land area and population, and its capital is the port city of Willemstad.

Wireless came to Curaçao very early.  In 1908, a Dutch warship, the Jacob van Heemskerck, brought the first wireless transmission equipment to Curaçao, and this was duly set up in Fort Rif at the mouth of Willemstad Harbor as a coastal wireless station.  The original callsign was CRC, though this was regularized to PJC a few years later.

That callsign, PJC on Curaçao, is reminiscent of the more familiar callsign PCJ which was the call of the well-known Dutch international shortwave broadcasting station back in the early days of radio.  In fact, in the pre-War years, it wasn’t unusual for radio journals to mix up the callsigns, with the Curaçao call sometimes being printed incorrectly as PCJ, instead of PJC.

In 1928, for the first time, a radio telegraph service between the Netherlands Antilles and Holland was established by PJC on Curaçao.  Two years later a similar wireless communication service was established between Curaçao and New York.

The first radio broadcasting service on the island was launched on 20 February 1933, and it too was installed in Fort Rif, as a function of the maritime radio station PJC.  The Dutch word for ‘broadcasting’ is ‘omroep’ – you may recall that the full Dutch name of Radio Netherlands was Radio Nederland Wereldomroep, Radio Netherlands World Broadcasting.  So in Curaçao, the new station was Curaçao Omroep, which they shortened to Radio Curom, taking the first three letters of Curaçao, and the first two of omroep.  It was officially a government radio broadcasting service, but operated by the Curaçao Radio Association, or CRV – Curaçaosche Radio Vereeniging.

The station was given the specific callsign PJC1, and emitted just 150 watts on 9091 kHz.  Reception was first reported in the USA in the club magazine of the International Short Wave Club (or, ISWC) in April 1937, and the station was heard periodically in North America.

In 1941, the same ISWC magazine proclaimed that Radio Curom would soon be upgraded to 2 kW; and in 1943, the station began relaying programming on behalf of AFRS, the American Forces Radio Service, on 5930 kHz using a new transmitter, PJC2, with a power of 3 kW.

A low-power medium wave station using the callsign KWJG was installed at the Hato airfield on Curaçao in 1943 also to relay AFRS for the American troops then based there.

A final listing during this era is found in a publication in New Zealand, which shows Radio Princess Juliana on 7250 kHz in 1946.  This apparently operated under the same PJC2 callsign previously used for the AFRS programming, and it was listed in the World Radio Handbook with 3 kW on either 7250 kHz or 5017 kHz from 1947 through 1953, though the last listing shows that the station had become inactive on shortwave.  Instead, in 1953, Radio Curom launched a medium wave service with a power of 3 kW on 722 kHz.  Subsequently, other medium wave stations, all commercially operated, were inaugurated on the island.

In 1958, Radio Curom’s 25th anniversary was celebrated with the production of an LP record of Caribbean music recorded in the Radio Curom studios – the first ever LP recorded in Curaçao.  It was published with the help of Philips in Eindhoven, in the Netherlands.

Interestingly, a report in the NASWA Journal states that Radio Curom was noted again on shortwave in the United States during 1960 with programming in the 31 metre band.

And then, in Jerry Berg’s second book ‘Broadcasting on the Shortwaves, 1945 to Today’, he states that Radio Curom was again briefly reactivated on shortwave in the 1970’s, when it was heard in the United States on 17513.5 & 20779 kHz.

The 1980 edition of the WRTH listed five medium wave radio stations in Willemstad on 850, 1010, 1230, 1500, and 1540 kHz, but as is the case in so many countries, broadcasting in Curaçao gradually migrated from the medium wave band to FM.  The last medium wave station, which closed in December 2022 after declaring bankruptcy, was the familiar Radio Curom, which then was using 10 kW on 860 kHz with the call PJZ86, and identifying on air simply as ‘Z86’.

So these days, there is no shortwave or medium wave broadcasting service left on the island of Curaçao, although a couple of dozen FM stations are listed, along with a number of online stations that webstream only.  

In its early years, Radio Curom was branded by the radio magazines of the era as being a poor verifier.  However, as time went by, that changed and many QSL cards were issued.  The highly desired QSL card from Radio Curom used to show a stylistic map of Curaçao with a tall antenna tower.

The maritime station on Curaçao, with which Radio Curom was associated, also issued QSL cards as verification of listener reports.  Two of their cards are known; one showing a map of the island, and a later one showing the figurative shield of Curaçao in color.

So, Radio Curom was indeed on the air on the shortwaves, many years ago, and apparently during three different eras, beginning in 1933 and ending in the early 1970’s.

Back to you, Jeff.

Radio Seabreeze resumes broadcasts

 

Radio Seabreeze is back in the air at 1395 kHz after a long time. The maintenance work has been completed and the antenna has been restored, allowing listeners in the Northern Netherlands to receive the transmitter again via mediumwave.

Let us know what the reception is like and leave a message in our guestbook or via our QSL page.

https://radioseabreeze.nl/2026/07/10/10-juli-2026-1395-weer-in-de-lucht/ (translated from Dutch)

1395 kHz is from the Grou Aquaverium site. It went off air at the end of January 2026 because of renovation work at the Aquaverium, including renewal of the roof where their antenna was sited. Seabreeze's other transmitter is on 1098 from Laren, further south near Utrecht.

U.K. Propagation Update

 

RSGB

GB2RS News Team | July 24, 2026

We said last week that there were no coronal holes to worry about. Yet two days later a massive crack appeared on the Sun, stretching over one million kilometres.

Luckily, this didn’t amount to much and it had little effect on HF propagation, but it does go to show that solar events can rapidly develop and that long-term forecasts can be tricky.

The solar flux index has increased over the past week, and was sitting at 150 as this report was being written. As we suggested earlier, geomagnetic conditions have been quiet with the Kp index generally below 3.5, which bodes well for HF.

Solar conditions have been good with only four M-class solar flares and no X-class events. Any coronal mass ejections, or CMEs, have been directed away from Earth.

We are still in the summer doldrums, so D-layer absorption remains high and maximum useable frequencies, or MUFs, are generally lower than in the autumn and winter. However, we have the IOTA contest this weekend, which is a great opportunity to work some far-flung DX. So why not dust off your radio and get on the air? With mainland Great Britain being an island, you might find you are in demand as EU-005!

Other DX to be worked this week includes RI0BW, the Arctic Legends IOTA DXpedition; 3B9HR from Rodrigues Island; PJ7/LA5IIA on St Maarten; TY5FR from Benin; E51CZZ and E51KEE on the Cook Islands; VU4R from the Andaman Islands; and VP5G operating from Turks and Caicos.

In the coming week, NOAA predicts that the solar flux index may fall back to 125 at first, and then down to around 108. Luckily, the Kp index is predicted to remain low, with a predicted Kp of 2, at least until the end of the month.

VHF and up:

There have been good examples of both tropo and Sporadic-E in the last week and there are reasons to continue with some optimism for the coming week.

This is still a good period for summer tropo. However, remember that hot days are the enemy of tropo over land, and it tends to be sea paths that survive throughout the day, whereas land stations have to make the best of nighttime operations.

That said, the main change in the weather pattern this coming week will be that the high pressure, which has been over the Atlantic just west of Britain, shifts into the continent and eventually out of reach by the end of next week.

So, the message is to get into the tropo while it’s here and use the latter part of the week for perhaps meteor scatter, with the Delta Aquarids peaking in the coming week. There is reserved optimism for this since it’s primarily a southern hemisphere event.

Rain scatter has been very hard to find recently but looks like making a comeback as the weather turns more unsettled with sequences of fronts crossing the country. Maybe only patchy weak fronts, but still worth considering.

The summer aurora prospects are staying on the marginal side, but watch out for Kp index values creeping above 5 before turning your beams north.

Sporadic-E, which is rolling along in main summer season fashion, has been very good lately and was producing a full set of bands, up to 2m, last Thursday 23 July.

As the weather turns a bit more unsettled, this could help with Sporadic-E. This could happen if the fronts move into the continent and weak jet streams, and possibly thundery cold fronts, create turbulence at the right sort of range over Europe. This will probably favour paths to Scandinavia and to the Balkans.

For EME operators, Moon declination reaches minimum today, 26 July, so Moon window lengths and peak Moon elevation are at their lowest value. 

With apogee yesterday, 25 July, path losses will decrease as the week progresses. 144MHz sky noise is high to start the week, peaking at over

2800 Kelvin today, 26 July, before slowly decreasing in the coming week.

The End of an Era: NHK Leaves Nauen

 

NHK World Japan is expected to conclude its remaining shortwave relay broadcasts from the MBR transmission facility at Nauen, Germany, on June 28, marking the end of the broadcaster's final use of the historic German relay site.

The broadcasts affected by the closure are:

UTC/frequency

Japanese to the Middle East, 0100–0300 on 9440 

Japanese to the Middle East, 0300–0400 on 11960 

Japanese to the Middle East, 0400–0500 on 13750 

Russian to Eastern Europe, 0430–0450  on 6165 

For many years, Nauen has served as an important relay facility for international broadcasters seeking coverage across Europe, Africa, and the Middle East. With the departure of NHK World Japan, another chapter in the long history of shortwave broadcasting from Nauen comes to a close.

It remains unclear whether NHK will continue these services through alternative transmission facilities. Some observers have suggested that replacement broadcasts could originate directly from Japan, though no official announcement has been made regarding future frequencies or schedules.

For DXers, the period immediately following June 28 will be worth watching. Monitoring the traditional NHK frequencies, as well as nearby channels in the 16- and 19-meter bands, may provide clues as to whether the broadcaster plans to maintain service to these target areas through other transmission sites.

As always, reports from listeners will help determine what changes, if any, appear on the bands after the Nauen transmissions fall silent.
