Shortwave listening and everything radio including reviews, broadcasting, ham radio, field operation, DXing, maker kits, travel, emergency gear, events, and more
I just checked Fred Osterman’s Shortwave Receivers Past and Present. It appears the CRM-R6A is a “double conversion super” with 16 tubes and typically weighs 92 lbs. They were manufactured in the US between 1965 – 1969 and cost $1795 when new. The CRM-R6A can be mounted in a rack, of course.
It’ll be interesting to see if someone meets the first bid amount of $750.
While certainly a promotional piece for Hallicrafters, this has great footage and captures a bit of the excitement of radio expanding into new frontiers. There is a discussion of how the radio was modified for military conditions as well as some innovations which were implemented to make such a system mobile.
As an aside, it never ceases to amaze me how clear and crisp black and white film technology of the time seems somehow better than the color images which replaced it. But that may just be me — a black-and-white guy living in a colorized world!
There is a second part to this video, as well as other WWII-era videos available on YouTube with a bit of searching, and of course don’t forget to check out the SWLing’s Shortwave Radio Archive page for more interesting shortwave audio old and new!

This NOS 51-S1 is headed for a record price for an Ebay sale. I have only seen one of these in this condition in my decades on Ebay. This is a rare rack version complete with box and original accessories. The preselector, also NOS, sold earlier today:
“I put the pic in Lightroom and pulled it out of the shadows.
It is definitely a Skyrider and not an SX-28.”
Wow–I’m amazed there was enough information in that photo to pull it out of the shadows! You can see the silk screening and the SEND-REC. switch in the lower right corner.
Again, here’s my Hallicrafters SX-24 Skyrider Defiant for comparison:
I know why they used a Skyrider in the film; the warm glow of the dials and signal meter were simply irresistible! (At least, they are for me!)
With the recent posts about shortwave radio in films (Star Wars and Star Trek), I remembered a scene from Avengers: Age of Ultron where I thought I spotted a vintage Hallicrafters receiver.
In the scene, Hawkeye (Jeremy Renner) is using an “old school spy method” to find the whereabouts of Black Widow (Scarlett Johansson). I remembered Haweye sitting in front of a 1940s era radio.
This weekend, I found the clip from the movie (first time I had seen it since the theatre) and sure enough, I’m positive this is a Hallicrafters. Click on the images above or below to enlarge.
I can’t quite determine the Halli model, though–can anyone ID it?
The images aren’t the best: the scene is dark and the radio at quite an angle. Still, there’s no mistaking that Hallicrafters glow.
My Hallicrafters SX-24
I think there’s a good chance it’s the same model I have in my radio shack: the Hallicrafters SX-24 ‘Sky Defiant‘–but I can’t quite confirm. Perhaps it’s an SX-28?

Over $2k for this receiver, which appears to be quite unique. It is not one of the well-known and quite rare Beckman 51J4s, and likely it was re-finished to give it the almost white-grey color it has.
But it does have an interesting tuning addition, what the seller calls a factory-installed 4:1 vernier knob. Regardless, it fetched about as much as any 51J4 has ever brought in on Ebay:
Thanks, Dan! That 51J4 is a beauty. I’m always amazed at the price Collins equipment fetches at auctions and even at Hamfests. You’re hard-pressed to find anything under $800 and rare units (like the 51J4 above) sell for so much more.
Someday, I’d like to add a Collins R-390A to my collection, but first I need to make room for it and start saving! My buddy, Charlie (W4MEC) has rebuilt several R-390s and I’ve no idea how he does it. The tuning mechanism alone is one amazing (and complicated) piece of engineering! Charlie loves a good challenge, though, and he’s certainly brought a few R-390s back into full service.
Sometimes when browsing eBay you’ll come across a hot item that wasn’t even on your wish list or Followed eBay Searches. This was the case for me early last month when I spotted a new listing for a Zenith Royal D7000Y-2 Trans-Oceanic that’s arguably the best performing T-O ever made. It’s not the most collectable (the final R7000 series has that distinction), but is the final model with the desirable band spread tuning arrangement. The D7000Y is also the last of the hand-wired Trans-Oceanics. Some claim this model has the best audio of the transistorized T-Os, too.
I have a soft spot in my heart for Zenith Trans-Oceanics, as the co-author of the “Royalty of Radios” reference book, the late Prof. John Bryant, was my best friend for many years. John also wrote books on Zenith’s corporate history and other models of Zenith radios. The transistorized Zenith Trans-Oceanics were unobtainable dream receivers for me when I was a teenager in the mid-1970s.
I watched this Buy-It-Now auction for three days and was very surprised it remained available, especially after noticing its superior condition compared to other auctions for the same model. Finally on the third day I pulled the trigger–I’m not a collector of vintage radios but I couldn’t miss the chance to let this fine old Zenith follow me home. At a Buy-It-Now price of $219 including cross-country shipping, it seemed like a no-brainer decision.
When the radio arrived–packed extremely well–it was in ever better condition than pictured and described (I’d call it 9.8 on a 10 scale). The package included the original hang tag, QA stickers, owners manual, service manual, marketing literature and even the original monaural earphone and AC power cord. All dial lamps and the chart light worked fine. The previous owner said the T-O was fully aligned a year ago, and indeed I found that the reception quality on the built-in whip antenna is great. I’d love to know where this receiver was stored for the last 38 years; it was clearly someone’s gently used, cherished Zenith.

Compared Against the Sony CRF-320
Besides simply enjoying receivers I get a kick out of comparing them against each other, and against various other ones owned by my radio hobby friends. Thanks to the loan of a vintage Sony CRF-320, I was able to directly compare it to my Zenith Trans-Oceanic Royal D7000Y-2 receiver. My friend’s CRF-320 is the equal of my Zenith in condition and quality. Each of us would like to own both of these radios!
This is an interesting pairing, since the Zenith was among the last of the premier, USA manufactured portable receivers (analog only, all hand-wired chassis), and the CRF-320 was an equally prestigious portable receiver of the “latest technology”–digital/analog readout with printed circuit board construction.
Once a leading receiver brand, Zenith did not react quickly enough to changing trends and business climate after the death of its founder, Commander Eugene F. McDonald. The 40 year old (1942-1982) proud line of Trans-Oceanics gave way to new, semi-automated methods of building receivers with inexpensive labor from Asia.
After an initial production run of the next (and last) R7000 series, manufacturing was moved to Taiwan. The receiver was built just as well as the previous Royal D7000, but used PCBs inside and the useful band spread frequency ranges were done away with (at the expense of ease of tuning). Still, Zenith T-Os couldn’t compete on price or performance against the Sony CRF-320, and the R7000 Trans-Oceanics were the last (and now most collectible) versions.
This YouTube video compares reception of these two vintage receivers with mid-morning signals on the 31 meter band, from the Seattle area:
Both radios were used with their built-in whip antennas although I couldn’t extend the Zenith’s its final four inches due to ceiling height in the room.
In my opinion, the CRF-320 is superior in keeping signals steady with its AGC, but the D7000Y-2 excels in audio quality and is neck-and-neck in most other respects. The Zenith may have performed a bit better with weak signals if the ceiling in my kitchen was a few inches higher! (Both radios have substantially long built-in antennas, and each are very well matched to their circuitry for excellent reception.)
There are many references around for the Zenith Trans-Oceanic series, but not a lot has been published on the CRF-320. Here is one page with good details on the Sony: http://www.shortwaveradio.ch/radio-e/sony-crf320-e.htm
I’ve been active on eBay since 1998. As with garage sales, the chances of an excellent “find” increase with the time spent in the pursuit. Sometimes you just get lucky though and find a very desirable item remaining unsold for days, such as this Trans-Oceanic! It’s all about being in the right place at the right time. Since I’ve bought the receiver I’ve yet to see any other D7000s of equal or better quality, despite some with Buy-It-Now prices of up to $450 plus shipping (edit 12/16: I spotted one that appears in equal condition to mine, but for a Buy-It-Now of $675 + $40 S/H).
