D.I.C.A.: Giuseppe’s latest homebrew portable antenna

Many thanks to SWLing Post contributor, Giuseppe Morlè, who shares the following antenna project:

Dear Thomas and SWLing Post Friends ,

I’m Giuseppe Morlè, iz0gzw, from Central Italy, Formia on the Tyrrhenian Sea…
Some time ago I had drawn this minimal HF antenna on paper…

I took advantage of the New Year’s Eve rain to be able to build it with the usual leftover scraps…

The system consists of a 35 cm tube with two separate windings of telephone cable on it, 2.5 m on each side, green and white…in the center I connected the 4 ends to X…

The green lead with the white and the white with the green to the variable capacitor and the other two leads to the RG58 cable that goes to the receiver.

I started the test and noticed that the agreement was possible from 7 to 21 MHz…

I then placed a long ferrite inside the tube…

I noticed a strengthening of the signal and consequently of the noise picked up and the chord dropped to 3.2 MHz.

Tests inside my shack showed decent reception on all ranges…in the evening on the balcony on 80 m. I could perfectly listen to a QSO between Italian stations.

Everything is still in the experimental phase and I think I will try this minimal system also in QRP transmission.

In this first video I explain how this minimal antenna is made:

The second video concerns a 20 meter test by car. The antenna is placed on the dashboard of the car inside:

In the third video, I explain how it works without the ferrite and with the ferrite inside the tube:

In this video you can see the test on 40 m. outdoors on the roof of the house:

The tests are carried out at home in order to understand what can be achieved in an environment that is difficult to receive.

I will do more outdoor tests and I think this small minimal antenna will receive better. I will keep you informed.

Thank you all for your attention and I wish you all a new year full of satisfaction.

’73 de Giuseppe iz0gzw.

Fascinating, Giuseppe! I love all of these brilliant little antennas you design out of your “junk” drawer! We look forward to hearing more about this antenna and any modifications you make to it!

The Yoto Player: Chris’ Unconventional Wifi Radio Alternative

Many thanks to SWLing Post contributor, Chris, who writes:

Hello Thomas,

As a long time SWLing Post reader, I wanted to pass along something you and your readers might find interesting in the subject of internet radios.

While I have many MW and SW radios in my collection, I have reluctantly researched some PORTABLE wifi radios recently with the full knowledge that the satisfaction of catching a marginal broadcast signal no longer exists with this technology. But I have stumbled upon a PORTABLE internet radio that is not marketed as an internet radio, and it was right under my nose (or at least in my house) for a year before I discovered this.

As a father of two young children, I recently purchased a Yoto Mini player for them and a Yoto Player for myself (well, for them too):

https://us.yotoplay.com/yoto-player

This was after the realization that aside from the juvenile look to the Yoto, it fulfills all of my requirements of a portable internet radio player that the big players like Sangean, Ocean Digital, Lemega, and others cannot seem to attain in one product:

      • 24 hour battery life, rechargeable
      • very strong WIFI connection that covers whole house (can be BT speaker too, for those who use that)
      • much better sound and solid build
      • simple operation
      • no dependency on the status of online station database (** more below)
      • $120 or less ($70 for Mini)
      • other “tech” features people might use, but not necessary

Essentially, you place a credit card sized content card in the Yoto, it reads the song information by RFID, and downloads it from your online account so that it can play pre-recorded books or songs with or without internet connection.

HOWEVER, you can add radio station URL links to be ‘burned’ to a Yoto card as well and connect to those radio stations through the player. I have tested this and it works. Some use cases are that you could place multiple stations on one card and select which one from the Yoto (each with a custom graphic image to identify the station), or you could put one station on each Yoto card to feel more like you’re actively switching stations. Or you could put different genres of radio stations (music, talk, etc.) on a different card.

There are easy ways to find the actual URL of a streaming radio station.

If some people are looking for an internet radio that connects to a worldwide station database, the Yoto does not do that. But I don’t see myself needing that, because I would rather just add my favorite 5/10/20+ stations and jump between those. Connection status or retirement of online station databases seems to be a common source of complaints in the internet radio reviews I have read.

Please tell me your comments, and/or feel free to post this as a discussion topic on your blog.

Thanks,
Chris

Wow–I was not familiar with this device, but as you say, in a sense it’s a very robust interactive audio device with incredible battery life. I like the fact that so much of it can be used offline as well. I’m sure readers will have some comments and questions! Perhaps you can share more of your experience in the comments section of this post!

Andrew Ikin of Wellbrook Communications has passed away

Mark Fahey’s Wellbrook Mag Loop antenna.

Many thanks to a number of SWLing Post readers who sent me this message–a re-post from the IRCA mailing list:

Death of Andrew Ikin- Wellbrook Communications
From: Tracey Gardner
Date: Thu, 04 Jan 2024 13:10:23 EST

I am the bearer of very sad news.

My good friend Andrew Ikin of Wellbrook Communications passed away on 25th October 2023 after a very short illness.

He was buried on 10th November, a day before his 79th birthday.

He is buried in the local churchyard in Beulah.

Andrew was internationally known and respected, his products were second to none and his reputation for customer service renowned.

I was lucky enough to count him as a friend and I will sorely miss him.
The amateur radio and radio listener fraternity have lost a true colossus.

Radio Prague’s 2024 QSL Card Series

Many thanks to SWLing Post contributor, David Iurescia, who shares the following article from Radio Prague:

Radio Prague’s 2024 QSL card series will be musical – and digital

To this day, Radio Prague International has kept up the decades-long tradition of QSL cards – postcards confirming receipt of reception reports to listeners. Every year, we have created a new series of postcards to send to listeners. In 2024, there will be something else new – in addition to the traditional printed versions, we will also start producing and sending digital QSL cards.

2024 is the year of Czech music – and so is the theme for next year’s QSL card series.

With a different QSL card for every quarter, Kristýna Marková’s graphic designs will bring you images inspired by the most famous Czech classical music names – Antonín Dvo?ák, Bed?ich Smetana, Leoš Janá?ek and Ema Destinnová.

The Times They Are A-Changin’

Many international radio stations, as they muted their shortwave broadcasts, also stopped issuing QSL cards. However, Radio Prague International continues to preserve this tradition.

Unfortunately, significant price hikes by the Czech postal service have forced us to make a few changes. From 2024, we will only send printed postcards to listeners who send us a printed postcard or letter themselves. Otherwise, we will send digital QSL cards to those who send us a message by email or via our web form.

We hope that our digital QSL cards will delight you as much as our printed ones have and that you will continue to be among our loyal listeners for years to come.
