Shortwave listening and everything radio including reviews, broadcasting, ham radio, field operation, DXing, maker kits, travel, emergency gear, events, and more
Many thanks to SWLing Post contributor, Dan Srebnick, who notes that the Raspberry Pi 4 mini computer was unveiled this morning by the Raspberry Pi Foundation.
This model has a number of upgrades we’ve all been waiting for:
I love the Raspberry Pi and own a number of models that I’ve employed in various projects. For example:
Two RACHEL-PI systems (English and French) I’m evaluating for use with ETOW
A stand-alone SDR station
What excites me most about the Raspberry Pi 4 is the improved processor speed and larger allotment of RAM (up to 4 GB). This could make the Pi a more effective stand-alone or portable SDR station. The dual monitor capability could also be a big bonus. And, of course, GigaBit ethernet speeds will help make the Pi a better/faster connected device.
When the Raspberry Pi 3B+ was introduced last year, I hesitated one day and had to wait weeks for the second shipment. Not this time! I purchased two 4GB units (in two different shipments as most suppliers have a maximum of one per customer) and hope to receive them by mid-July.
If you’re interested in pre-ordering the Raspberry Pi 4, check out the Raspberry Pi Foundation website for recommended resellers.
Do you plan to grab a Pi 4? Would you like to share a recent project with us? Please comment!
The Yle public broadcaster has told its ‘carissimi auditores’ (dear listeners) that “everything passes, and even the best programmes reach the end of the road. This is now the case with our world-famous bulletin, which has broadcast the news in Latin on Friday for the past 30 years”.
The core members of the ‘Nuntii Latini’ (News in Latin) team – Professor Tuomo Pekkanen and lecturer Virpi Seppala-Pekkanen – have been with the five-minute bulletin since it was first broadcast on 1 September 1989, although other newsreaders and writers have joined since.
Professor Pekkanen took gracious leave of Yle, saying that, “judging by the feedback, Nuntii Latini will be missed around the world – and we send our warm thanks to you all for these past years!”
[…]Latin news addicts won’t have to suffer withdrawal symptoms for long, as the language’s greatest remaining bastion, the Catholic Church, launched its own weekly news bulletin in Latin the same week as Yle’s programme went off air. [read more here]
The key difference is that Yle offered a broad world news agenda, rather than Vatican Radio’s more focused ‘Hebdomada Papae’ (The Pope’s Week) – not to mention the fact that the Catholic Church uses its own, Italian-influenced pronunciation, rather than the Classical version preferred by scholars.[…]
The GE 7-2990A (left) and Panasonic RF-B65 (right)
This has been a very crazy and radio-active weekend!
It started with a busy Friday that was capped off with the BBC Midwinter Broadcast and then continued into Saturday with a Parks On The Air activation and Field Day at Mount Mitchell State Park.
The Midwinter Broadcast has never been an easy catch here in North America–after all, the BBC aim their signals to Antarctica–but I always manage to receive the program with only a portable and I’m almost always travelling on the day of the broadcast.
This year, I was actually at home and could have used one of my SDRs at home to snag the broadcast, but it’s become a bit of a tradition to listen in the field, so that’s what I did.
Knowing how difficult it would be to receive the broadcast–especially given the poor propagation–I reached for one of my “Holy Grail” portables: the Panasonic RF-B65.
The Panny RF-B65 is a portable DX hound!
I never take only one radio to the field, though, so I decided it was time to give the hefty GE 7-2990A a little outdoor time on the Blue Ridge Parkway.
The GE 7-2990A
I’ve only had the GE 7-2990A for a few months. It came from the estate of my dear friend Michael Pool (The Professor) who passed away earlier this year.
This particular radio has quite an amazing history–remind me to share the story someday–but I’ll always cherish the 7-2990A because it was one of Michael’s favorites.
I knew the GE was one of Michael’s favorite mediumwave receivers, but I wasn’t sure how well it would perform on the shortwaves. Turns out, it’s quite an amazing HF receiver!
Out of the the three Midwinter Broadcast frequencies (5875, 7360, and 9455 kHz), I could receive the 7,360 kHz signal from Ascension Island best.
I was quite surprised with the 7-2990A’s ability to pluck this weak signal from the ether. Although the video doesn’t do it justice, the GE’s excellent audio fidelity made listening more enjoyable compared with the much smaller RF-B65.
And, yes, that’s my faithful brown and white listening companion, Hazel, in the background. In truth, she was less interested in the broadcast and more interested in finding squirrels!
Your Midwinter recordings–stay tuned!

I’ve already received about twenty emails from SWLing Post readers with audio and video recordings of the Midwinter Broadcast. Thank you!
If you would like to submit your recording, and you haven’t yet, please do so by email (thomas *at* swling.com) so I don’t overlook it. Remember to link to your video so that I can easily embed it on the upcoming post. Please don’t send me duplicate emails as it makes the sorting process more difficult.
I’ll try to find recordings linked via Twitter and Facebook, but it’s much more difficult to sort those in comments and know for sure that I’ve discovered them all.
Please note that, due to my schedule, it will likely be two weeks before the final post is published. I appreciate your patience and understanding!
I spotted a £3 semi-rigid pencil case that looked like it might fit my new PL-680, and when I got it home, found that it was a great fit.
I cut out the internal flap that holds the pens with scissors, and the result speaks for itself.
Wow! That’s a brilliant case for for the PL-680, Mark! That exterior color will also ensure you never lose it in the wild. Thanks for sharing this tip. What a fabulous bargain at £3! Post readers in the UK, take note!
Encore – Classical Music on Shortwave – Broadcast on Sunday afternoon in Europe and USA

If you live in North America and have an interest in becoming a ham radio operator, this is the weekend to check out what amateur radio is all about, and meet local radio enthusiasts.
“ARRL Field Day is the single most popular on-the-air event held annually in the US and Canada. On the fourth weekend of June of each year, more than 35,000 radio amateurs gather with their clubs, groups or simply with friends to operate from remote locations.
Field Day is a picnic, a camp out, practice for emergencies, an informal contest and, most of all, FUN!
It is a time where many aspects of Amateur Radio come together to highlight our many roles. While some will treat it as a contest, other groups use the opportunity to practice their emergency response capabilities. It is an excellent opportunity to demonstrate Amateur Radio to the organizations that Amateur Radio might serve in an emergency, as well as the general public. For many clubs, ARRL Field Day is one of the highlights of their annual calendar.
The contest part is simply to contact as many other stations as possible and to learn to operate our radio gear in abnormal situations and less than optimal conditions.”
Field Day is always the fourth full weekend of June, beginning at 1800 UTC Saturday and running through 2059 UTC Sunday.
Many Field Day sites have a GOTA (Get On The Air) station where non-licensed individuals are welcome to play radio. It’s a fantastic way to try your hand at transmitting with a little guidance and encouragement from the more experienced. Indeed, even if there is no GOTA station, you will often be invited to try out the mic.

This year, like last, I’ll be home and plan to spend Field Day with my buddy Vlado (N3CZ) in the Field! We plan to operate from Mount Mitchell State Park for a few hours. Later, we’ll likely stop by some local clubs on the air.
Keep in mind that there are many shortwave listeners among the amateur radio community; indeed, many hams became interested in the hobby through SWLing.

Every year, the BBC broadcasts a special program to the scientists and support staff in the British Antarctic Survey Team. The BBC plays music requests and sends special messages to the small team of 40+ located at various Antarctic research stations. Each year, the thirty minute show is guaranteed to be quirky, nostalgic, and certainly a DX-worthy catch!
After successful listener events from years past, I’m once again calling on all SWLing Post readers and shortwave radio listeners to make a short recording (say, 30-60 seconds) of the BBC Antarctic Midwinter Broadcast today and share it here at the Post.
The broadcast will take place at 21:30 UTC today.
Many thanks to SWLing Post contributors Richard Langley and Alan Pennington who confirm the following broadcast frequencies:
5875 kHz
7360 kHz
9455 kHz
If you would like to participate in our BBC Antarctic Midwinter Broadcast recording event, please read our original post which includes all relevant details.
