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:

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).

Best solution to restore a vintage plastic radio chassis?

Sony-ICF550W-FrontFriday, I brought home an untested, slightly grimy, Sony ICF-5500W. I purchased it through Goodwill for $20.

Sony-ICF550W-Right

I crossed my fingers as I put three C cells in the radio and turned it on. Fortunately, I was rewarded with brilliant audio. I tuned the ‘5500W on AM/mediumwave and heard CFZM,  500 miles to my north, and Radio Reloj, 860 miles to my south. A quick scan on the FM dial revealed that I could also hear all of my local benchmarks. Whew!

Other than the dial needing a little calibration, and DeOxit on a few pots, it’s in excellent mechanical shape.

Sony-ICF550W-Left

I started cleaning the radio last night using Q-tip cotton swabs and a vinegar/water solution.

I’d like to restore the hard plastic chassis’ original shine, though.

I was tempted to reach for some Armor All, but stopped myself short. I know it would give the ICF-5500W a nice shine, but would it cause any long-term damage to the black plastic or clear dial cover?

I know there are vintage radio restorers among the SWLing Post readership. Can someone offer advice on what’s the best product to use (or not use!) on my ICF-5500W?

Brittle ribbon cables: James cautions Sony ICF-2001D and ICF-2010 owners

Sony-ICF2010

Regarding the Sony ICF-2001D (or ICF-2010 in North America), SWLing Post contributor James Patterson writes:

I have a comment on the Sony ICF-2010. In New Zealand it is called the ICF-2001D, as labeled on it.

I bought the ICF 2001D at a sale. Brought it home and it seemed to perform almost perfectly on all bands. In fact I was very suprised on how well it worked. Audio was excellent, sensitivity was great, even the Air Band received very well. But I’m a very keen SSB DXer, meaning I monitor the Single Side Band [SSB] utility stations like HFAir, Marine, military, etc. so I needed to check the SSB in the radio.

[O]n official frequencies like 8.86700 HF AIR, it was well off, and came up readable around 8.86500, even with the tuning speed mode set to “slow”. So I then decided that with the age of the radio, over time it has drifted off zero beat, so I would need to re-align the BFO/SYNC coil.

I looked up on the internet at the signal board, and located the correct coil. Having the batteries out of the radio, I plugged in the DC power supply and retuned that coil and got the speech correct at 8.86700. I also checked the universal time signal on both USB and LSB and it was “Bang on”.

I was very pleased with myself, meaning I now had a Sony ICF-2001D working in perfect condition.

But just then the radio went dead. At this stage I still had the board lifted up, as I had just finished the realignment. I could not understand, after all my work, what had happened. So having a good look at the wires and the board, to my most disappointed dismay, I noticed one of two ribbon cables–Sony called it a “Flexible circuit board” had snapped right across and come apart.

There are two ribbon cables on the board. This was the short one. So,with the slightest lift of the board, this one snapped. I then felt the cable and noticed how frail it was with a piece just falling off. The ribbon cable as I call it, had become most fragile with age and probably heat from the sun(?) over the years the previous owner had it.

So all of a sudden I found I had a ICF-2001D no more. I looked at the other board, the CPU board underneath and noticed that ribbon cable was joined to the other ribbon cable side by side to become one cable, and spot soldered onto the board. Also on shifting the CPU board to view underneath it, the selective speed plastic slide switch snapped off.

Note broken ribbon cable and broken switch.

[B]y now, I was in a state of complete disarray to say the least. Never was I going to have the ICF-2001D operational again.

So guys, be most careful if you ever need to do any repairs or realignment of that radio–remember the ribbon cables become very fragile and will just snap right across as mine did with the slightest lift of the board. I wish I had known this, and I would have taken the cable out of it’s socket first,then when finished, plugged it back in, and radio would still be working. But to realign it, the cable would need to be connected anyway. So I hope this does not happen to anyone else, especially if you don’t have spare parts, as I don’t have.

So Im keeping this one for parts now,and hopeing to replace it with either another 2001D or its older brother ICF 2001. I do have a small collection of vintage portable short wave radios; they all have SSB, and all work very well. Most have the varible BFO control knob and that seems to suit me better, rather than a radio with tuning steps and needing to perhaps realign it. I think the ICF-2001D is very similar to my ICF-SW7600G with only a few memories and no tuning knob. I think the older ICF-2001D would still be my radio of choice though.

In this photo I have tried to replace the ribbon cable with an old Computer ribbon cable,but that job failed because the board underneath has the ribbon cable spot soldered on.There are two ribbon cables both joined side by side to become one.So the idea of replaceing the broken ribbon cable would disturb the other having to cut it away from it.

James’ restored Sony ICF-5800H

Sony Vintage radio ICF 5800H 001

SWLing Post contributor, James Patterson, has recently restored a Sony ICF-5800H. James sent me a few photos and I decided to post them here.

Sony Vintage radio ICF 5800H 003

I absolutely love the design of Japanese analog radios from this era. They have signal meters, large backlit dials, carry straps, and proper large controls–buttons, switches and knobs–that can even be operated when wearing gloves in the winter.

Video: Shortwave listening and radio astronomy

Sony-ICF-SW100

On Thursday I attended an event at the Pisgah Astronomical Research Institute (PARI)–location of the 2015 SWLing Post DXPedition.

During a break, I had a couple of free hours, so I reached in my messenger bag and pulled out the Sony ICF-SW100: a radio that has quickly surpassed all others as my favorite EDC (everyday carry) radio. It has so many useful features in such a small package!

Radio astronomy observatories are ideal locations for impromptu shortwave radio listening as there is little to no radio interference/noise present.

PARI-26E-and-26W

PARI’s “Building 1” and the 26 West (left) and 26 East (right) radio telescopes.

While the weather on Thursday was gorgeous, HF band conditions were…well…miserable. There was very little to hear other than China Radio International, Radio Havana Cuba and a few other blow torch broadcasters.

Still, time signal station WWV was on my mind since I had just purchased Myke’s new edition of At The Tone and have been reading your excellent comments with early memories of listening to WWV and WWVH.

I tuned to 15 MHz and, of course, there was reliable WWV in Fort Collins, Colorado on frequency. Though WWV’s signal was relatively strong (despite the conditions) I turned on the SW100’s sync detector because fading (QSB) was pronounced at times.

Here’s a short video of the ICF-SW100 on a picnic table in the middle of the PARI campus. That’s PARI’s 26 (meter) West telescope in the background:

Bill’s simple Sony SRF-59 passive loop antenna modification

Sony-SRF-59-AM-Loop-Antenna

In reference to our previous posts about the Sony SRF-59 ultralight receiver, SWLing Post reader, Bill Mead, writes:

“As someone who doesn’t normally open the backs of radios, this is my mod on my ultralight. All it takes is a bit of electrical tape to hold the belt clip on the loop.”

That is, indeed, a brilliant and simple mod. The SRF-59 inductively couples to the loop antenna, so no soldering is needed; simply tape the belt clip to the loop, making sure the position is convenient for tuning the SRF-59 and the loop’s capacitor.

You can find passive loop antennas ranging from $19 to $50 US. The Grundig AN-200 and the Terk AM Advantage are two models currently on the market. Here are a few places you can check prices:
