New miniature antenna can operate wirelessly inside of a living cell (Tech Explorist)

An intracellular antenna that’s compatible with 3D biological systems and can operate wirelessly inside a living cell.

A new study could allow scientists to create cyborgs at a cellular scale, thanks to MIT Media Lab for designing a miniature antenna that can operate wirelessly inside a living cell. This could have applications in medical diagnostics, treatment, and other scientific processes because of the antenna’s potential for real-time monitoring and directing cellular activity.

Scientists named this technology Cell Rover. It represents the first demonstration of an antenna that can operate inside a cell and is compatible with 3D biological systems.

Deblina Sarkar, assistant professor and AT&T Career Development Chair at the MIT Media Lab and head of the Nano-Cybernetic Biotrek Lab, said, “Typical bioelectronic interfaces are millimeters or even centimeters in size and are not only highly invasive but also fail to provide the resolution needed to interact with single cells wirelessly — especially considering that changes to even one cell can affect a whole organism.”

The size of the newly developed antenna is much smaller than a cell. The antenna represented less than .05 percent of the cell volume in research with oocyte cells. It converts electromagnetic waves into acoustic waves, whose wavelengths are five orders of magnitude smaller, representing the velocity of sound divided by the wave frequency — than those of the electromagnetic waves.

Mid Century Television – live, local and unpredictable late 1950s television (Southgate ARC)

In the late 1950s television networks ruled the airwaves from 7 to 11 PM, but outside of that timeslot television was live, local and unpredictable.

Jim Hanlon, W8KGI, worked as a summer relief engineer at Cincinnati’s WCPO-TV from 1956 to 1958. At that time WCPO-TV did not have any video recording technology, so all local TV was live TV and provided a refreshing dose of live programming, equipment failures and production creativity that been lost in today’s pasteurized, homogenized TV ecosystem.

Join Jim as he recalls what it like producing live TV programming in the early days of television broadcasting.

Radio Waves: Stories Making Waves in the World of Radio

Welcome to the SWLing Post’s Radio Waves, a collection of links to interesting stories making waves in the world of radio. Enjoy!

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

Ukraine’s ‘Army FM’ Radio Adapts To Full-Scale War (CoffeeOrDie)

KYIV, Ukraine — During the early morning hours of Feb. 24, as Russian missiles struck targets across Ukraine in the opening hours of the full-scale war, the Ukrainian military’s Army FM radio station went underground.

The team of seven army officers and about 10 civilian personnel abandoned their studio on the top floor of a downtown Kyiv building and relocated into a nearby basement. Inside the dank and dark underground space, they connected a mixing board and a couple of laptops to a mobile radio system, which the station’s reporters had previously used to report from the Donbas trenches.

“I just grabbed my Kalashnikov and went to work,” said Oleksandr Yurchenko, 32, a Ukrainian army second lieutenant assigned to Army FM.

While a Russian invasion force advanced to the outskirts of Kyiv in the war’s perilous first few days, the Army FM team stayed at their posts and worked in six-hour shifts to keep their programs running 24/7. They constructed makeshift beds from shipping pallets and stocked the basement studio with food and water. Body armor vests and Kalashnikovs occupied all available shelves and empty corners.

From this jury-rigged basement studio, Army FM continued to transmit information and entertainment programs to listeners across Ukraine — including into territories Russian forces invaded and occupied. [Continue reading…]

SDRplay Updates on Hardware Shortages (RTL-SDR Blog)

As we all know many electronic components are currently in shortage, and this global shortage is affecting some SDR manufacturers like SDRplay. Recently on their blog SDRplay have provided some updates on their hardware shortage situation. They write:

As we have mentioned before, due to the worldwide shortage of electronic components, we are suffering from production delays at both our manufacturing subcontractor operations here in the UK. This means that many of our resellers have completely run out of RSP1A and RSPdx devices.

However we are pleased to say that this week, we have been able to build some additional units. This means that by the end of next week (February 25th), our resellers should have more stocks of RSP1A and RSPdx. More RSPduos are promised for mid to late March.

It is highly likely that even after the latest production runs are delivered, some of our resellers will run out again in the weeks ahead. Meanwhile we are working to do all we can to secure more critical components for our manufacturers. This includes tweaks to the designs so that they can accommodate alternative more readily available parts.

Many thanks to customers who have been left waiting to buy, and to our resellers for your patience as we navigate though this situation.

A list of our authorised resellers can be found here: https://www.sdrplay.com/distributors/

Voice heard ’round the world: Voice of America museum near Cincinnati a historical marvel (The Columbus Dispatch)

WEST CHESTER, Ohio — Imagine, if you will, a voice so strong that it shakes the very foundations of global tyranny.

In the early days of World War II, a group of Americans, including President Franklin Roosevelt, actor and director John Houseman and Cincinnati entrepreneur Powell Crosley Jr. imagined such a voice, one that could counter Nazi propaganda in Hitler’s own backyard.

They named it The Voice of America.

Today, the National Voice of America Museum of Broadcasting, 8070 Tylersville Road, occupies the site from which the service beamed its message around the world for 50 years beginning in 1944, recounting its history and remembering the people, especially Crosley, who made it possible.

100th Anniversary Celebration of the First Trans-Atlantic Radio
Transmission of a Message by Amateur Radio (1BCG.org)

Saturday, December 11, 2021

On a cold winter night on December 11, 1921, members of the Radio Club of America were able to send the first amateur radio message from a small shack in Greenwich, CT to be received by American Paul Godley in Ardrossan, Scotland. This transatlantic test proved the value of shorter wavelengths – long considered worthless to long distance communications and through their success ushered in the age of global shortwave radio communications. The 1921 message was sent one-way. Acknowledgment of Paul Godley’s reception of 1BCG’s massage was sent back to the US via the Marconi high power radio transmitter in Wales.

The Antique Wireless Association, in association with the Vintage Radio and communications Museum of Connecticut (VRCMCT) in Windsor, CT, the Radio Club of America, the American Radio Relay League, and the Radio Society of Great Britain, participated in the 100th Anniversary special events held Saturday, December 11, 2021.

For the 75 th anniversary celebration of the 1BCG accomplishment in 1996, AWA members Bob and Mike Raide constructed a replica of the 1921 transmitter. For this 100th celebration, AWA Museum Staff restored the replica. The VRCMCT in Windsor CT has graciously offered to host AWA operation of the replica transmitter during the evening of December 11th. The 1BCG replica transmitter was placed on public display at the VRCMCT Museum during the day of Saturday December 11, 2021. [Continue reading the full report at the 1BCG website…]

GB100BBC launches 1st Jan 2022
With thanks to the London BBC Radio Group

Within minutes amateur radio stations around the UK and throughout Europe were clamouring to contact the special BBC station and secure a prized entry in the logbook.

The London BBC Radio Group was granted an extended special event radio licence by the regulator OFCOM, to operate the station throughout 2022.

The amateur radio activity is one of many events organised to celebrate 100 years of the BBC, which began broadcasting from Savoy Hill in 1922 as the British Broadcasting Company, moving to the iconic Broadcasting House in 1932, gaining a Royal Charter as the British Broadcasting Corporation.

The London BBC Radio Group has a growing membership which includes engineers, journalists, producers and on-air talent in both TV and Radio. The group is independent but hosted and supported by the Corporation.

The group was launched in 2017 by a handful of radio enthusiasts to revive a long and rich history of amateur radio at the BBC dating back to the Second World War.

The ‘radio shack’ at the BBC’s headquarters, Broadcasting House in central London, was officially opened by the then Director General, Lord Tony Hall, with an over-the-air message of congratulations. Lord Hall was subsequently bestowed Honorary membership of the club. [Click here to read at the Southgate ARC…]

Czech radio switches off MW and LW as 2022 starts (Mike Terry via the Southgate ARC)

Prague (dpa) – Radio reception on medium wave (MW) and long wave (LW) has been history in many parts of Europe for years.

Now, in the Czech Republic, at least the public broadcaster will stop transmitting on MW and LW as the new year starts on Saturday.

The powerful transmitters on the frequencies 270, 639 and 954 kilohertz could also be received in large parts of Germany.

The reason given for the move was the widespread availability of terrestrial digital radio DAB+ and the high costs of broadcasting.

Those still listening using medium waves were to be persuaded to switch with a campaign. The radio station Cesky Rozhlas set up a telephone hotline to answer questions.

It was not known at first whether the transmitters would be retained or used for other purposes.

The antenna of the medium-wave transmitter Liblice B east of Prague is considered the highest structure in the Czech Republic, with a height of 355 metres.

Impuls, the most-listened to private radio station, wants to remain faithful to medium wave for the time being. It broadcasts its second programme, with pop and country music, on analogue transmission.

Radio Waves: Stories Making Waves in the World of Radio

Many thanks to SWLing Post contributors Trevor R, Andrea Bornino, Wilbur Forcier, and the Southgate ARC for the following tips:

First radio transmission sent across the Atlantic Ocean (History.com)

Italian physicist and radio pioneer Guglielmo Marconi succeeds in sending the first radio transmission across the Atlantic Ocean, disproving detractors who told him that the curvature of the earth would limit transmission to 200 miles or less. The message–simply the Morse-code signal for the letter “s”–traveled more than 2,000 miles from Poldhu in Cornwall, England, to Newfoundland, Canada.

Born in Bologna, Italy, in 1874 to an Italian father and an Irish mother, Marconi studied physics and became interested in the transmission of radio waves after learning of the experiments of the German physicist Heinrich Hertz. He began his own experiments in Bologna beginning in 1894 and soon succeeded in sending a radio signal over a distance of 1.5 miles. Receiving little encouragement for his experiments in Italy, he went to England in 1896. He formed a wireless telegraph company and soon was sending transmissions from distances farther than 10 miles. In 1899, he succeeded in sending a transmission across the English Channel. That year, he also equipped two U.S. ships to report to New York newspapers on the progress of the America’s Cup yacht race. That successful endeavor aroused widespread interest in Marconi and his wireless company. Continue reading →
