Giuseppe’s Crossed Loop and the “VariabilOne”

Many thanks to SWLing Post contributor, Giuseppe Morlè (IZ0GZW), who shares the following:

Dear Thomas and all friends of SWLing Post,

I’m Giuseppe Morlè iz0gzw from central Italy on the Tyrrhenian Sea, Formia.

A few days ago at a fair for radio amateurs in Latina, I bought an excellent very large variable capacitor–those of ancient military radios–and I found a splendid antique knob with a fantastic gear ratio.

I called this VariabilOne and it consists of two sections of 250pf each. It’s very portable and can be applied to any loop with crocodile clips.

I built another cross loop made up of 2 turns the internal loop, 35 cm. and only one turn for the external loop, 40 cm.

I can tune frequencies from 3.500 to 20.0 MHz. The crossed loop is strongly directive given the two loops that work together being joined on their ends.

I have made some demonstration videos and it is a pleasure for me to share them for our entire community (see below).

Thanks to you and I wish you all the best for you and your family.
Greetings to all.
73. Giuseppe iz0gzw.

Giuseppe, thank you once again for sharing your brilliant homemade antenna projects with us. I absolutely love that monster variable cap and tuning whee! What a thing of beauty–and obviously your loop is very effective.

Thank you as always, Giuseppe!

Polish Radio launches another programme for Ukrainians (Radio Poland)

Public broadcaster Polish Radio is on Thursday launching a new weekly programme for Ukrainians escaping the Russian invasion and their compatriots residing permanently in Poland.

The hour-long broadcast will be delivered in Ukrainian, airing every Thursday at 7 p.m. on Polish Radio’s mobile app, web player and DAB+ platform, the public broadcaster’s IAR news agency reported.

Listeners will hear advice on where to find help, how to apply for assistance available to refugees, and how to obtain information about their loved ones, according to IAR.

Also, the programme will feature news on how the Polish government, local authorities and charities are working to support refugees from Ukraine, and on Poland’s efforts to facilitate Ukraine’s entry into the European Union and the NATO alliance, IAR reported.

The weekly broadcast is prepared and hosted by journalists from Polish Radio’s External Service, also known as Radio Poland.

‘Countering Putin’s false narrative’

“The priority is to counter the Putin regime’s false narrative,” said Radio Poland’s Director Andrzej Ryba?t.

He added: “We’ll be reporting at length on Polish-Ukrainian relations, as well as the policies of the European Union and NATO. In addition, Ukrainians who had been forced to flee their country will hear about what is happening in the places they had had to abandon as a result of the Russian aggression.”

As the programme develops, it is also set to feature Polish-language courses for Ukrainians seeking shelter in Poland, and items on Ukrainian music and culture, IAR reported.

Ever since the Russian invasion of Ukraine began on February 24, Polish Radio has been airing news bulletins in Ukrainian on several of its channels, as well as launching a 24-hour live audio and video stream about the war on Youtube.

It is also broadcasting the signal of Ukrainian Radio on its web player and DAB+ platform so that the people escaping the Russian attack can listen to programming in their native tongue, executives said.

Poland on Thursday reported it had admitted nearly 2 million refugees fleeing Russia’s invasion of Ukraine.

Radio Waves: Stories Making Waves in the World of Radio

Because I keep my ear to the waves, as well as receive many tips from others who do the same, I find myself privy to radio-related stories that might interest SWLing Post readers. To that end: Welcome to the SWLing Post’s Radio Waves, a collection of links to interesting stories making waves in the world of radio. Enjoy!

Owning a shortwave radio is once again a subversive activity (Hackaday)

An abiding memory for a teen fascinated by electronics and radio in the 1970s and 1980s is the proliferation of propaganda stations that covered the shortwave spectrum. Some of them were slightly surreal such as Albania’s Radio Tirana which would proudly inform 1980s Western Europe that every village in the country now possessed a telephone, but most stations were the more mainstream ideological gladiating of Voice of America and Radio Moscow.

It’s a long-gone era as the Cold War is a distant memory and citizens East and West get their info from the Internet, but perhaps there’s an echo of those times following the invasion of the Ukraine. With most external news agencies thrown out of Russia and their websites blocked, international broadcasters are launching new shortwave services to get the news through. Owning a shortwave radio in Russia may once again be a subversive activity. Let’s build one! [Continue reading…]

Radio’s Hardware Problem Grows (Radio Ink)

(By Ed Ryan) When was the last time your station gave away a slick looking radio as a promotion (batteries included)? How many more echo dots will radio stations keep giving away before they realize they may be pushing listeners to find something else to listen to?

In a teaser for Edison Research’s upcoming Infinite Dial presentation at Podcast Movement’s Evolutions next week, the research firm reported that the number of Americans who say they do not have a single radio in their home continues to rise.

In the 2020 Infinite Dial, performed before the onset of the COVID-19 pandemic, just under one-in-three Americans age 12 and older reported not having a single radio in their home, according to Edison. In 2022, that number is now 39%.

Fourteen years ago, only 4% of respondents said they had no radios at home. Continue reading →

Many thanks to SWLing Post contributor, David Iurescia LW4DAF, who shares a link to the following announcement from Vatican Radio:

Vatican Radio increases shortwave broadcasts to Ukraine and Russia

From next Monday the Pope’s radio station will expand its Ukrainian and Russian programmes. The increase of shortwave frequencies aims to empower the Radio’s outreach in its mission to communicate the Gospel message and to “read” current events through this perspective.

By Vatican News

From Monday, 21 March, Vatican Radio will increase its shortwave broadcasts to Ukraine and Russia. In addition to the two daily broadcasts (afternoon and evening) in the two languages, the morning programmes to Moscow and Kyiv will last twenty minutes longer.

“The decision,” Massimiliano Menichetti, head of Vatican Radio Vatican News explains, “was taken with the agreement of the entire management team of the Dicastery for Communication, at this time when war is raging, in order to better respond to our mission: to bring hope, the Pope’s words and the reading of facts through the light of the Gospel to the whole world.”

In these past weeks, he added, thanks to a network of direct contacts that support the work of our reporters, we are trying to give comfort to those who are suffering and to ensure timely information.

The frequencies of Vatican Radio, the pages and posts of Vatican News in 51 languages (including English and Italian in sign language) aim to not leave anyone alone, even in the awareness of the power of prayer”.
