About

Aacharya J.C.Bose is well known as the “Father of Wireless Communication”.

Acharya Bose’s demonstration in 1895 & 1897 predates all.

Bose transmitted wireless signals to a distance of a mile. Popova in Russia was still trying remote signaling at this time & the first wireless experiment by Marconi was not successful until May 1897.

Bose is a pioneer in microwave optics technology.

Bose’s invention of 1-centimeter to 5 millimeters radio waves is being used in radars, satellite communication& remote sensing.

Bose’s concepts from his original 1897 papers are now incorporated into a new 1.3 mm multi-beam receiver on the NRAO (National Radio Observatory) 12 Meter Telescope.

Bose anticipated the use of P-type& N-type semiconductors & hence 60 years ahead of his time. Bose developed the use of GALENA crystals for making receivers.

In Bose’s presentation to the Royal Institution in London in January 1897, he speculated on the existence of electromagnetic radiation from the sun. This radiation from the sun was not detected until 1942.

My Dad and I took a road trip to tour the 1 MW FM community tower in Crestwood, MO, serving the entire St. Louis metro area combining 10 FM radio signals into two antenna systems.

Special thanks to the Audacy engineers who allowed us to take a peek at their (very clean!) transmitter rooms and equipment!

Has WTWW left shortwave?

I recently learned from a few reports on Twitter that WTWW left shortwave for good on November 9, 2022 and will now only broadcast over the internet. I missed this announcement on the air and WTWW’s website doesn’t seem to reflect this information yet.

The WTWW wikipedia page has already been updated, however, with WTWW’s services noted in the past tense and the following addition was made this week:

On November 9, 2022, WTWW announced it would discontinue all shortwave operations, with intent to continue streaming the programming as long as it was feasible. Ted Randall cited a massive increase in transmitter usage fees (the majority of that being from electricity cost) that the station could not realistically pay. The station signed off for the last time that night, with its final programming including a farewell message from Randall encouraging listeners to continue listening to the Web stream, a string of listener requests from WTWW’s automated system, and the final song being a rendition of “America the Beautiful” by one of Randall’s favorite recording artists, Ronnie Milsap.

Can anyone confirm if WTWW has indeed stopped all shortwave transmitting? Please comment.

BBC centenary marked at first national radio transmitter (BBC News)

The BBC’s 100th anniversary has been marked in the town that enabled it to make nationwide radio broadcasts.

Opening on 27 July 1925, the Daventry Transmitter was the world’s first long wave transmitting station.

Known as 5XX, it was on Borough Hill in the Northamptonshire town and its first transmission was with the a poem called “Daventry Calling…”.

Sophie Good from the town’s museum said: “Daventry has got a strong affiliation with the BBC.”

The BBC chose the position so the transmitter could cover the maximum land area.

It brought the total audience within listening distance to 94% of the population.

When it opened, the poem by Alfred Noyes was followed by speeches from the postmaster general, external and the mayor of Daventry, introduced by Lord Gainford, BBC Chairman.

The then Prime Minister Stanley Baldwin sent a message, published in the Radio Times, which said he saw “Daventry as another milestone on the road to the social betterment of our people”. [Continue read at the BBC…]

The BBC is celebrating its 100th birthday (NPR / AP)

LONDON — The British Broadcasting Corp. marked 100 years of broadcasting on Tuesday, a century after a group of wireless manufacturers founded the company and began filling the airwaves with its first daily radio service.

The BBC was founded on Oct. 18, 1922, in London and daily broadcasting began a month later. The broadcaster is marking its centenary with a series of special programs, including a guest appearance from King Charles III on The Repair Shop, a program featuring expert craftspeople restoring antiques.

Actress Jodie Whittaker will make her last appearance as the Time Lord on a special episode of Doctor Who on Sunday, before Ncuti Gatwa takes over the role. [Continue reading…]

Campaign to help WRMI after extensive hurricane damage

Our friend Jeff White, General Manager of WRMI is trying to repair extensive damage to the WRMI antenna farm post hurricane Ian. A GoFundMe has been created to help WRMI with repair costs. Even small donations add up!

Jeff White provides the following details:

Hello,

WRMI has a rich history of supplying news, information and entertainment to the world from our Okeechobee, Florida Transmitters.

Hurricane Ian damage to our antenna farm is so extensive, it has knocked us off the air to Europe and Africa.

We need your help to get us back on the air again to transmit to Europe and Africa news, information, religious programming and entertainment.

We have no insurance for the antenna farm due to the huge cost of insurance premiums.

We are desperately asking for help around the world to get us back on the air again to Europe and Africa. Your help is paramount to WRMI returning to the air in the many countries in Europe and Africa.

Your help will allow WRMI to rebuild the transmission towers destroyed by Hurricane Ian that are pointed towards Europe and Africa.

Keith discovers a Radio Bougainville recording on the Shortwave Archive: “A 50-year old tape takes me back”

We’ve published thousands of off-air recordings on Shortwave Radio Audio Archive over the past decade. They’re freely available for everyone to search and download.

For those of us who work on the archive, it’s a pure labor of love. We are not compensated for the time and effort we put into running and curating it, although we use Patreon and Coffee Fund contributions to help pay for the site and online archives.

Quite frequently, our recordings are discovered and are intensely meaningful to individuals. Listening to radio recordings has an amazing ability to summon up memories and moments in time.

We recently discovered the following article on the blog PNG Attitude written by Keith Jackon. Keith has kindly given us permission to post it in its entirety here on the SWLing Post. Thank you, Keith, and we’re pleased this recording was so relevant to you:


A 50-year old tape takes me back

KEITH JACKSON

NOOSA – It had dropped into my Twitter feed via @Laselki, the account of the Lebanon-based Arab Amateur Radio Network, and @Stret_Pasin, a valued supporter and one of my 8,700 Twitter followers.

It had originated in Ontario, Canada, from the historic village of Ancaster close by the US border and Niagara Falls.

It was a fleeting recording of a shortwave broadcast.

Map showing location of Ancaster, Canada

A broadcast from Radio Bougainville transmitted 51 years ago on 21 October 1971, which had travelled 13,300 km to Ancaster and been recorded.

Then saved on a cassette tape until, for some reason, recently retrieved and shared.

“Sound is a bit crackly,” wrote @Stret_Pasin, “but this will bring back memories of Radio Bougainville.”

Truer words never were tweeted.

When you link to the brief recording here (scroll down to the black audio bar), you will pick up in rapid succession the sound of chanting to the famous Bougainville kaur flute, then an announcer’s voice and finally a snatch of Bougainville string band music.

Click here to listen on the Shortwave Radio Audio Archive.

I thought I recognised this sequence as the pre-recorded station identification put to air each time the station’s transmitters were fired up at Toniva, just south of Kieta, from a switch in the main studio down a ladder beside my house.

But the more I listen to it, the less convinced I am of its provenance.

All I can say for sure is that anything the captured snatch of radio was broadcast at about 12 noon on Bougainville on 22 October 1971.

This was at a time when Radio Bougainville usually broadcast for 11 hours a day in three separate sessions: 6 am – 9 am, 12 noon – 2 pm and 4 pm – 10pm.

In a small town in Canada it was late morning the day before, and a young Dan Greenall was tuning his Hallicrafters shortwave radio seeking out distant stations he would register as finding in the ether.

Even in our modern digital age, there are shortwave junkies who ferret out remote radio stations and seek QSL cards: written proof of reception. (One issued by Radio Bougainville in 2016 is pictured here.)

QSL reception confirmation from NBC Bougainville, 2016

’I heard this at such time on your station; tell me it is true.” And we’d check the log and return a QSL postcard. Yes, you had indeed heard our station.

Collecting these cards became popular with radio listeners 100 years ago and continues to this day

Dan had been doing just that 51 years ago when he happened upon a distant signal struggling through heavy interference to be captured by his outdoor copper wire aerial and delivered to the sturdy Hallicrafters S-52 receiver.

Keith’s appointment to manage Radio Bougainville was greeted by this headline in the Bougainville News

Dan has written for the Shortwave Radio Audio Archive:

“The morning of 21 October 1971 provided some of the best reception of Papua New Guinea stations in the 90 metre band that I ever experienced.

“These stations were rare visitors to my headphones but I was able to make a couple of short recordings of two PNG stations that morning, and they have survived to this day on that same audio cassette (now 51 years old).

“This one of Radio Bougainville begins with a local chant followed by announcement on the hour. The station ran 2.5 kw and their signal made it over 13,300 km to my receiver that day.

“Audio quality is passable considering the recording was made using an open mic to the speaker of the Hallicrafters S-52.”

Technical data:

Broadcaster: Radio Bougainville
Date of recording: 21/10/1971
Starting time: 1100
Frequency: 3.322.5 MHz
Receiver location: Ancaster, Ontario, Canada
Receiver and antenna: Hallicrafters S-52 using a longwire antenna

When I linked to the thin signal that had managed to land so far away so long ago, I was momentarily overcome with emotion.

I had known those sounds so well from too many early mornings wondering whether the breakfast announcer would arrive in time to open the station.

A recording something like that told me he’d arrived, fired up the transmitter and was ready to begin proceedings.

Through the static of 51 years – two-thirds of my life – came a once-familiar sequence of bamboo flute / announcer / stringband, transporting me back to a time when I was young and in my first management job which, bad bits and all, I was enjoying as if born to it.

Keith Jackson at the time of his appointment to Radio Bougainville

They were tough years for the people of Bougainville, especially in the villages around Kieta and its hinterland.

Bougainville Copper had started to dig the ore that produced great quantities of copper, gold and silver on alienated land amidst an alienated people.

Despite the volatile social and political climate, I had enjoyed the challenge of Bougainville.

I felt I’d been made for it and that it was making me.

And I enjoyed working with talented station staff, most from Bougainville, like Tom Kathoa, Sam Bena, Perpetua Tanuku, Justin Kili, Aloysius Sahoto, Aloysius Nase and Aloysius Rumina – most now gone from our midst. That’s what 51 years does.

And that simple recording – made so long ago and so far away – brought it all rushing back.

You can read more about my Bougainville years here in Brink of Secession.

So thanks to Dan Greenall, the Arab Amateur Radio Network and @Stret_Pasin for giving me a free ticket to fly back more than half a century. I really enjoyed the trip.

Also, a very special thanks to Dan Greenall and all of our contributors on the Shortwave Radio Audio Archive.

How the BBC (still) sends audio to transmitter sites (Hackaday)

Running a radio station is, on the face of it, a straightforward technical challenge. Build a studio, hook it up to a transmitter, and you’re good to go. But what happens when your station is not a single Rebel Radio-style hilltop installation, but a national chain of transmitter sites fed from a variety of city-based studios? This is the problem facing the BBC with their national UK FM transmitter chain, and since the 1980s it has been fed by a series of NICAM digital data streams. We mentioned back in 2016 how the ageing equipment had been replaced with a modern FPGA-based implementation without any listeners noticing, and now thanks to [Matt Millman], we have a chance to see a teardown of the original 1980s units. The tech is relatively easy to understand from a 2020s perspective, but it still contains a few surprises. [Continue reading at Hackaday…]

Receivers Introduced At Pre-IBC Event To Be Seen At RAI On Sep 10th (DRM Consortium)

This year’s IBC DRM virtual event, held on 6th September, was very well received by many participants world-wide. The much-awaited session on DRM receivers gave the listeners and viewers the opportunity to learn about new, hot off the press, receiver products and solutions in this sector.

A new cost-effective DRM solution developed by CML Microsystems in conjunction with Cambridge Consultants in the UK, is just one example. Their product is a multi-band broadcast DRM receiver module that makes it quick and easy for manufacturers to build DRM radio sets. The module supports DRM and analogue reception in the AM and VHF bands. Applicable IP royalties are included in the module price. The module also supports a remote controlled mode and thus can serve as the basis for full-featured DRM radio sets. The module is scheduled to be available to industry partners from Q1 2023.

Gospell from China presented their entire range of well-established and full-featured DRM receivers consisting of desktop and pocket radios, with support for EWF Emergency Warning Functionality and Journaline text service. In addition, Gospell unveiled their new car radio for easy integration, the Stereo Digital Radio Receiver GR-520. All models provide DRM reception across all DRM broadcast bands.

The Swiss company Starwaves announced three upcoming DRM receiver solutions: A complete and full-featured DRM and analogue AM/FM receiver module available to receiver manufacturers, with automotive-grade tuning and fast scanning across all DRM frequency bands and support for EWF Emergency Warning Functionality and Journaline text service. A first consumer receiver model built on this DRM module will be the W2401 desktop radio priced at €79. An even more advanced receiver at 99€ will in addition feature a built-in WiFi hotspot for web browser access to the DRM content. All Starwaves receivers can be enhanced with DAB+ functionality if required by a local market.

Starwaves also offers the DRM SoftRadio App for Android phones and tablets, which upgrades any device by connecting an analogue RF SDR dongle to a full-featured DRM receiver. The app is available in major app stores including Google, Huawei and Amazon.

Exciting DRM receiver solutions for professional applications and device manufacturers were presented by Fraunhofer IIS (Germany), such as the automotive receiver kit software SDR, and the DRM MultimediaPlayer Radio App as the basis of professional and consumer-grade radio implementations.

NXP, the leading, global semiconductor manufacturer, showcased their complete portfolio of automotive qualified suite of DRM chipsets for car receivers for all DRM broadcast bands.

Other companies from India, such as OptM and Inntot, as well as the South Korean manufacturer RF2Digital contributed to the pre-IBC DRM virtual event with videos presenting their solutions for DRM use in desktop radios, mobile phones and in cars.

CML Microsystems/Cambridge Consultants, Gospell, Starwaves and Fraunhofer IIS will also be present in Amsterdam during the IBC expo on the 10th September together with other key DRM members, such as BBC, Encompass, Nautel and RFmondial. IBC visitors participating in the two DRM sessions at the Fraunhofer IIS booth and at the Nautel booth will experience live demonstrations of the new DRM receivers and modules.

Selected news from the presentation on September 6th including from the DRM receiver section are available as a free download: https://s.drm.org/KJr9.

Germany: New Entry-Level license class ‘N’ on its way (DARC via Southgate ARC)

DARC reports on the planned introduction of an entry-level amateur radio license, it will be limited to just 10w EIRP in the 144 and 430 MHz bands but they can build their own equipment

A translation of the DARC post reads:

Today [June 7], the Federal Ministry for Digital Affairs and Transport presented the draft of a new amateur radio regulation that will bring some innovations for all radio amateurs.

The chairman of the DARC e. V. and the Round Table Amateur Radio (RTA), Christian Entsfellner, DL3MBG was pleased: “The new regulation implements long-standing requirements of the DARC and the Round Table Amateur Radio. Remote operation will finally be allowed in the future. The Ministry has also implemented our demand for a beginner class, which has existed since 2008.

This makes it much easier to get started with amateur radio.” While the existing classes E and A are raised in level due to the introduction of new topics from digital technology, class N focuses on operational knowledge, regulations and basic knowledge of the technology.

Holders of the new Class N will be allowed to transmit on 2m and 70cm with a maximum power of 10W EIRP. “The new entry-level class should offer access to amateur radio in particular to young people and older people in accordance with international requirements,” explains board member Ronny Jerke, DG2RON. The legally stipulated self-build right is not restricted, so even beginners can develop, set up and put into operation radio devices or hotspots themselves.

The exam will follow a cumulative system, e.g. B. is known from the US amateur radio test. First of all, the exam for class N is taken, which already contains all questions from the areas of operational knowledge and regulations. The technical test for class E and then for class A can then be taken.

“The examination catalogs developed by the DARC for the three classes are structured in such a way that the content and questions are not repeated, i. H. Content that has already been examined in a lower class no longer plays a role in the examination for a higher class. So all future radio amateurs go through the exams of class N, through E to class A. It should be possible to take all the exams in one day.

The previously unregulated remote operation has been included in the new amateur radio regulation. Holders of license class A may in future operate amateur radio stations remotely and also allow other radio amateurs to use class A. Another important innovation concerns the training radio operation, which will be possible in the future without a separate training call sign. Instead, adding the prefix “DN/” makes any Class E or Class A callsign a training callsign.

The RTA now has 4 weeks to comment on the draft regulation. The board and the departments of the DARC have already started to examine the text of the ordinance in detail and will report promptly.

The press release from the Federal Ministry for Digital Affairs and Transport can be found at
https://bmdv.bund.de/SharedDocs/DE/Pressemitteilungen/2022/065-kluckert-amateurfunkverordnung.html

Attached to the press release is a draft of the second ordinance amending the amateur radio ordinance. This can be found as a PDF file at
