One of the highest prices ever paid for a Collins 51J-4

Collins-51J4Many thanks to SWLing Post contributor, Dan Robinson, who writes:

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.

eBay Find: the Zenith Trans-Oceanic Royal D7000Y, with Comparisons to the Sony CRF-320

ebaySometimes 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.royalty of radios book

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.

Eugene_F._McDonald_the_Commanderand_founder_of_ZenithOnce 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:

https://www.youtube.com/watch?v=Uli6DPRJkX8

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

Jay Allen’s excellent article on restoring a Zenith T-O Royal D7000 has very clear photos of the receiver’s interior: http://radiojayallen.com/zenith-royal-7000/

Moral of the Story?

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).

Michael comments on the Squires Sanders SS-IBS

Regarding the Squires Sanders SS-IBS Dan recently spotted on eBay, SWLing Post reader, Michael Black comments:

[The Squires Sanders SS-IBS is] a legendary receiver that either brought new ideas to receivers, or brought them to the amateur radio level.

There’s an article in QST in 1963 from Squires about this new stuff, I’ve never seen it so I don’t know if he’s talking in abstract terms, or revealing this receiver.

A big difference is that there’s no RF amplifier before the mixer, and the mixer is balanced. But he throws some of that out by going to double conversion, I assume for tuning reasons. The first IF is 500KHz wide, the first oscillator is crystal controlled and the second oscillator is variable, as seen in top end receivers of the day. The alternative would be a tuneable oscillator that was switched per band (instability from the switch, and the higher the band, the higher the frequency, hence stability) or mixing the tuneable oscillator with a crystal oscillator before feeding the first mixer, which can cause spurs without proper filtering).

The second IF is 1MHz, and having a filter so high was relatively new, though maybe some rigs had moved up to HF filters at the time.

It apparently is fussy about the antenna, or matching, because of the lack of RF amplifier.

Soon there’d be receivers that converted to 9MHz or so directly, saying goodbye to most image problems. Heathkit had a general coverage receiver later in the sixties that had an IF, with crystal filter, at 1680KHz, a relatively cheap receiver with much greater image rejection on the higher bands. The ham band only Heathkit HR-10 used the same IF and filter.

Then a bit later, synthesizers arrived that made it much easier to build better receivers.

There was a wave of building using the 7360 balanced mixer used in this receiver, and frontend q-multipliers to deal with the lack of front end selectivity. But as semiconductors and ICs came along, it became much easier for mixers to be balanced or double balanced.

Thanks for this insight, Michael–sounds like the Squires Sanders SS-IBS was quite the innovation of its time. Thank you for sharing!

Guest Post: A Late Summer Visit to Howard Mills’ Radio Restoration

Many thanks to former VOA correspondent and noted DXer, Dan Robinson, for the following guest post:

A Late Summer Visit to Howard Mills’ Radio Restoration

-Dan Robinson

The end of summer is a wistful time, as we begin to mourn the passage of warm days and anticipate the arrival of autumn.

For those of us in love with shortwave, even in these waning days of HF broadcasting, August brings changes in propagation that herald the approach of improved reception, thoughts of getting antennas in shape, and preparing receivers for the new DX season.

It’s also a time when Hamfests are winding down for the year — for me, it’s still great fun to attend these and see what equipment is available.

A few months ago, I and fellow Washington, DC area SWL Dave Malick took the opportunity to visit a couple of Hamfests. At one of these, in Berryville, VA, I ran across someone who over the years has become somewhat of a legend in the field of radio restoration — Howard Mills.

Howard lives in rural West Virginia, at a point about equidistant from Harper’s Ferry and Sheperdstown. That’s about an hour or so from DC and the immediate Maryland suburbs. From DC, you drive out Rt 270 to Frederick, Maryland and then up Route 15 and 340.

It’s beautiful country — on the way you pass through small towns, past farms, and in late summer, roadside stands selling huge ears of corn and about every type of vegetable, along with peaches and apples of every type and size.Rack mounted equipment

Back in the late 1990’s I first became aware of Howard Mills when I brought my Collins 51J4 to him for refurbishing.   Howard is one of the few persons remaining in this country capable of going through classic tube receivers from top to bottom.

A visit to Howard is an experience everyone should have at least once in a lifetime. Restoration activities take place in the lower/ground level of his home.

Outside there are some amazing antennas, long wires, and beams which support both his amateur radio and receiver activities.
DSCF7558Under a porch, covered in tarps, are some of his latest equipment and parts acquisitions, from thousands of tubes to some of the rarest radios and transmitter items one may ever see.

Howard at his home in WVA

Inside, you find a wonderland of receivers. You name it, Howard has it. In racks, there are specialized Beckman 51J4s, SP-600s, AR-88s and R-390/As, Eddystones, and others. In another room, you see some of the most beautiful, and collectible and valuable, American and foreign-made radios dating back to the earliest days.

Rare Eddystone

On tables in one portion of the basement of Howard’s place, you find several R-390s in various stages of refurbishment. One, he notes (probably among his “keepers” ) was found still new in its original crate (how I would love to have that one!).

On the day Dave and I visited, the purpose was to pick up one of the most beautiful R-390s I have ever seen — a Capehart that was refurbished by Howard in 2007 and placed in a custom cabinet, complete with an easy-left-off top, similar to the HQ-180 design. This black beauty is now sitting in my shack at home.

R-390A Capehart

Howard has been at it for many decades, as I said. A conversation with him is a voyage through radio history, punctuated by references to a range of major radio manufacturers. He clearly loves what he does, though one wonders how much longer he will be at it.

Howard emphasizes by the way that his work is in restoring TUBE radios — he doesn’t get into solid state. There are a few well-known receivers in his place — I noticed an ICOM IC-R72 and a JRC NRD-535– but most of what you see are the classics that we have all come to know and love.

DSCF7529

His primary specialty appears to be the 51J series. A link to him on the Collins site notes that his main focus is on A line equipment, J series, and 32V series, but he is certainly capable on a number of models, including as I saw, HQ-180s and AR-88s (http://www.collinsradio.org/howard-mills/)

I was able to take some photos of Howard’s operation and offer them to SWLing Post readers here. At this point, Howard remains in business. He has had customers from all over the U.S. and I assume around the globe.

For each refurbishing job, Howard provides an extensive print out of every single modification and component replacement he does, along with the results of sensitivity and calibration tests done for each set.

Please do note that Howard makes clear that basically as long as it takes him to refurbish a radio — is as long as it will take.   If you give him one of your radios, you basically agree to it being with him for several months if not longer. He does have a backlog.

R390A New

Things like sandblasting front panels for R390s (I am not certain to what extent he does this himself or out-sources this particular aspect) also takes time.   And the detail with which he approaches a breakdown of an R390/A, evidenced by the sets I saw in process, is quite extraordinary and time-consuming.

Howard gets mostly superb reviews from those who have used his services. If you look him up on the Internet, and he has time for you to visit, it’s an experience you will always remember, though it’s not that I would suggest a crowd descend on him.

Hope everyone enjoys the photos — I had intended to get this article to Tom much sooner than October. Keep in mind, of course, that though Howard is one of the last to do this kind of work, there are a few others, including Chuck Rippel in Virginia.

We are indeed lucky to have anyone still doing this work. We know they do it not just as a business, but out of a love for this wonderful old equipment.

Many thanks, Dan, for taking us on this virtual tour of Howard Mills’ collection and workshop!

Your Capehart R-390A is absolutely gorgeous; Howard, no doubt, brought it back to mint status through loving, considerate restoration. What a great addition to your collection, Dan.

Thank you, again,  for sharing your guest post.

Anniversary of Sputnik I Launch & Radio Moscow

radio_moscow_sputnik_card_side1

Many thanks to SWLing Post contributor, Richard Langley, who writes:

Yesterday, 4 October, was the anniversary of the Soviet Union’s launch of Sputnik I, the first artificial Earth satellite. The launch heralded the beginning of the space age. Sputnik I’s Doppler-shifted radio transmissions on 20.005 and 40.002 MHz led to the development of the U.S. Navy Navigation Satellite System (Transit) and the equivalent Soviet system (Tsikada) and, eventually, to GPS and GLONASS and the other modern global navigation satellite systems.

The Sputnik I radio signals were picked up by many shortwave listeners. The 20 MHz signal was close to that of WWV and so was easy to find. And, apparently, WWV turned off its 20 MHz transmitter during some of Sputnik I’s passes over the U.S. so as not to interfere with reception.

There are several good sites on the Web with information about Sputnik I and its radio signals including:

Sometime in high school, I received a card from Radio Moscow celebrating the launch of Sputnik I [see above]. Perhaps it was issued in 1967 for the 10th anniversary of the launch.

Richard: You never cease to amaze me! Thank you so much for sharing all of this Sputnik I information and resources! That gorgeous QSL Card is perhaps my favorite design from Radio Moscow.

An eBay caution: some sellers are out for a buck–or hundreds

RF2200
SWLing Post contributor, Dan Robinson, has recently noticed exorbitant prices demanded by certain sellers on eBay. Dan writes:

As readers of SWLing Post know, Ebay prices–at least asking prices–can often go completely off the scale.

While it’s true that prices can be as high as the market will bear, some recent examples are cases in point. The RF-2200 by Panasonic was an amazing radio for its time, competing with the SONY 5900W and some other models back in the early days of sophisticated portables. The 2200 was known, and is still respected, for its directional AM loop antenna, and is a prized part of the stables of many SWL’s today.

But let’s face it…only a 2200 found new-in-the-box, or in [like]-new condition, should fetch anything over $250-300. Other examples recently include a DX-302 for which the owner was seeking something like $1200. Price inflation has also been seen with SONY ICF-6800Ws. The [difference] with these sets is that they truly are in new or 10.0 condition, worth several hundred dollars.

New SONY ICF-2010s–[and] there are still some circulating that are new-in-the-box or in [like]-new condition–can and do bring prices north of $400, sometimes more. So do new-in-box SONY ICF-SW100s if they are complete with all accessories, in the box–but beware, they should be the newer modified versions and not the old version (you can tell this by looking at the hinge on the SONY, which should have a notch to indicate the revised version of the radio).

Another classic portable that deserves somewhat higher pricing is the Panasonic RF-B65. In [new-in-the-box] condition, these can go for more than $300.

So, [unless] you’re seeing astronomically high prices for RF-2200s, stop and think about it. These are old portables, and you should not be paying exorbitant prices–UNLESS you [encounter] a time capsule with a radio in the box that was never used. Even so, buyers need to ask multiple questions of sellers to protect yourself.

I agree completely, Dan. If you want to purchase an item at a fair market price or even a bargain, you must do your research before simply using the “Buy It Now” option on eBay. There are plenty of sellers who charge fair prices still; leave the stratospheric-priced items on the eBay shelf.

Tecsun-PL-365-Ebay-Crazy-Price

A case in point (above): never mind the grammar error in the above listing, the $125 “Buy It Now” price for the Tecsun PL-365 is frankly excessive. The PL-365 is identical to the CountComm GP5/SSB–a radio I recently reviewed–and is available new from Universal Radio for $79.95 plus shipping. And since there are currently no other listings for the PL-365 on eBay (I’m not sure why) this price might appear reasonable to a new buyer.

This same seller initially offered the Tecsun PL-365 for a much higher price–in excess of $180, I believe. While this seller has excellent ratings, and no doubt would stand behind the product, the markup is simply too high for me to endorse (hence, no eBay link here).

In the past, I’ve also noted a semi-rare vintage radio–a “boat anchor” variety with a market price of perhaps $1,500–up for auction with a first bid amount in excess of $20,000 US! Yet I felt confident of the $1500 market price because I checked and cross-referenced it in Fred Osterman’s Shortwave Receivers Past & Present, which provides fair market values.

So, while I continue to support eBay, which remains one of the most secure platforms from which to buy unique and vintage goods on the open market, I want to encourage readers to heed Dan’s warning: research all pricing before making radio purchases on eBay…and keep the holes out of your pockets. Note that I will never directly link to unreasonable eBay listings.
