Shortwave listening and everything radio including reviews, broadcasting, ham radio, field operation, DXing, maker kits, travel, emergency gear, events, and more
But it has been off the air for the past weeks due to some minor health issues. The program was interesting in that besides Slow Scan photos, he also did other digital modes using FLDigi.
Some of the test included multiple digital signals in the same waterfall.
When I went to website today to check to see if there were any updates on when it might return to the air, I discovered that he is doing a podcast: Daily Minutes Podcast. Following is podcast feed:
This podcast is a combination of new items as well as some re-runs of earlier Show Scan Radio programs. They also are a combination of English & Dutch. The June 13 & 14 podcasts are about off-shore radio. Very interesting and enjoyable.
The Jun 12 & 14 podcasts include a re-run of an earlier Slow Scan Radio Show in the last thirty minutes of the podcast.

Many thanks to SWLing Post contributor, Vlad, who shares some images and a video of a new QRP transceiver in development: the Discovery TX-500 by a company called lab599.
Specifications have not been published yet, but we have confirmed a few details from the manufacturer:
10 watts PEP
HF plus 6 meters
Weight 570 grams (1.25 pounds)
Voltage 9 – 14 VDC
105 milliamps at 13.8 VDC and with backlit display on
CAT control via USB and using Kenwood codes
I/Q outputs
Weatherized
Expected availability autumn 2019
Target retail price is $700 US
Product website is forthcoming
All of the following images came from the Discovery TX-500 gallery on Instagram:
For someone, like me, who loves playing radio in the field (Parks On The Air and Summits On The Air) this looks like an ideal rig. It’s one of the only ham radio transceivers I’ve seen that is weatherized to some degree (how much, we don’t know yet).
I don’t see a speaker on the TX-500, so I’m guessing it might require a mic/speaker combo or an external speaker of some sort? I also don’t see a built-in ATU, but at $700, I certainly wouldn’t expect one.
With a power consumption of 110 milliamps at 13.8 VDC, this little transceiver should run for ages on a modest battery pack.
This is certainly a fascinating prototype QRP transceiver. If the Discovery TX-500 transceiver can be produced and marketed at $700 with all of the features mentioned so far, it should certainly fly off the shelves. They can certainly take my money!
Of course, I will plan to grab one of these for review. I’m also eager to see how this little SDR transceiver might perform on the broadcast bands.
We will post post TX-500 updates and details as they become available. Bookmark the tag Discovery TX-500 and stay tuned!
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!
