Many thanks to SWLing Post contributor, Robert Yowell, who writes:
I was visiting the US Air Force Museum [Friday] and walked through “Columbine III” which was the Lockheed Constellation used as Air Force One by President Eisenhower from 1954 until he left office. In the back of the cabin was a nice cozy area where this Hallicrafters receiver was installed – ostensibly for the passengers to listen to news or other events while in flight.
I am sure one of your readers will be able to identify which model it is.
Can you imagine flying in this gorgeous Lockheed VC-121E four prop aircraft and listening to HF radio from a built-in Hallicrafters set? Wow…
Thank you, Robert, for sharing these photos. The National Museum of the US Air Force is one of my favorite museums in the world. I bet I’ve visited it more than a dozen times over the past decade–always a treat and always something new to discover!
Post readers: Can you identify this Hallicrafters model? Please comment!
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!

Check out the attached picture. It is from a preview of tonight’s episode of “Young Sheldon.” In it, Sheldon and Dr. Stergis are listening to an antique shortwave radio. I think it is a Capehart International Radio Model 88P66NL.
Also in the preview is an active loop receiving antenna. The show is supposed to be about Sheldon when he was young, back in about 1985. I don’t think active loop antennas were very popular at that time! Maybe they got the timeframe wrong on the use of the antenna. What do you think?
What a catch! I love the flip-up cover on the Capehart although I’m sure in daily use it might have been a bit unhandy. 🙂
Regarding active magnetic loop antennas, like you, I don’t remember them being around much in the mid 80s, although I know the technology was available. I imagine they were used in speciality commercial and military applications. Like you, I’m guessing we didn’t have as many noisy switching power supplies which make them such a necessity these days. I remember happily DXing with my Zenith Transoceanic in the middle of my house in the mid 80s. Those were certainly the days!
Post Readers: Do you know of any active magnetic loop antennas that were used in homes in the mid 1980s and before? If so, please comment!
Evidently, the NJARC has been posting live video feeds of their meetings and events for quite some time, but recently YouTube changed their policy and now requires a minimum of 1,000 subscribers for live feeds. At time of posting, my subscription brought their number to 700–they need at least 300 more.
If you’d like to support the NJARC (and learn a thing or two about radio restoration–!), consider subscribing to their channel.
Many thanks to SWLing Post contributor, Cap Tux, who shares this eBay find: a Dieter Rams Braun T1000CD.
I must say, £675.00 is a lot of money, but I’m not so sure it’s an inflated price for the Braun T1000CD. I believe I’ve seen them fetch even higher prices and the condition of this unit is excellent.
Here’s the seller’s description:
I bought this radio from an Italian colleague in 1983 when I worked in Nigeria. I am the second owner from new. It has been dry stored in a box at my home for for most of the last 35 years. It is in very excellent condition with only the most minor blemishes to the case. Comes with original paper work and circuit diagram numbered the same at the radio. Please see all the photos. I had this serviced and realigned by Graham at East Coast Wireless. I have just checked all the controls and apart from the dial light they all work.
I’m sure a Dieter Rams collector will grab this unit in short order. Frankly, if I had the radio funds for such a purchase, I’d be tempted. I don’t own a single Rams’ designed radio.
Thanks again, Cap! One of the great things about eBay is finding the occasional gem like this and simply admiring the design.
Many thanks to the Southgate ARC who notes this recently published 1947 silent film from the Radio Society of Great Britain:
The RSGB has released a vintage silent black and white video of an Amateur Radio Direction Finding (ARDF) field day held in 1947 at Chipping Barnet which was then in Hertfordshire
The Incorporated Radio Society of Great Britain titled the video – D/F Field Day (North of the Thames) May 18th 1947. It has been added to the many amateur radio videos that can be viewed on the Society’s YouTube channel.
One thing that’s apparent from the video is the difference in the age range of those who participated in amateur radio in the late 1940’s compared to today.
Pages 69-70 of the RSGB Bulletin (forerunner of RadCom) for October 1947 contained a fully illustrated report on the North of the Thames ARDF event as well as the South of the Thames event held on July 6, 1947.
The two leading affiliated societies on May 18 were from Essex:
1st Romford and District Radio Society
2nd Southend and District Radio Society
The two clubs swapped positions for the July 6 event.
Fascinating! I love how everyone wore proper attire and much of the equipment was home brew. I imagine operators were happy to go back to field and enjoy all sorts of radio activity so close on the heels of WWII.
Spread the radio love
