A repair story: Vlado’s fix for the classic Sony ICF-SW100

In June, I made a small leap of faith and purchased a (dead) Sony ICF-SW100 from Universal Radio (see the listing on right).

ICF-SW100-Used-NonWorking You see, for many years, I’ve dreamed about owning this wee little receiver, now a classic among tiny radios, but used ones are typically too expensive for my modest budget.

This time, seeing the ad at Universal, I spoke with Universal Radio directly to obtain more details about their defunct unit; while they simply didn’t know what was wrong with the Sony, they were able to very accurately describe its cosmetic and functional condition…I took a deep breath, and decided to take a chance on it anyhow.

In full disclosure, I have a secret weapon in my camp: my talented friend, Vlado (N3CZ), who is not only the most adept electronics engineer/technician I’ve ever known, but one who truly welcomes a challenge. The thought had occurred to me as I admired the wounded Sony, Wonder if Vlad would like to take this on–?

The answer, of course, was Yes! So I dropped the DOA Sony off at Vlad’s home last week. He disassembled the radio, only to discover that my ICF-SW100 was a victim of the (dreaded) damaged ribbon cable.

A short history of the Sony ICF-SW100 and SW100S

These radios are indeed brilliant, incredible performers for their miniscule size. Yet the first generation of ICF-SW100 radios–those produced before the fall of 1997–have a design weakness: the ribbon cables which connect the upper and lower portions of the radio’s clamshell design eventually fail. Multiple openings and closings bend and cut the cables, rendering the otherwise remarkable little radio useless.

SWLing Post contributor, Dan Robinson, recently shared his knowledge about the ICF-SW100 series. Dan notes:

SW-100 Seekers Beware

As shortwave veterans know, the classic SONY miniportables — SW-1, SW-100(S) and SW-07, represented some amazing technological achievements. SONY managed to shrink some fantastic technology into these receivers, including (with the last two in the line) — SYNC capability. The SW-07, which was the last of these receivers, still brings some high prices on Ebay.

But if you are searching for the ICF-SW-100S there are some things to consider and beware of. As everyone knows, the SW-100 suffered from the well-known ribbon-cable failure problem. SONY addressed this problem in later serial numbers, and changed the design of the radio case.

Modified SW-100s have a notch where the top cover meets the base.

There are some dishonest sellers out there who are trying to pass off older version SW-100s as modified ones. Usually, the tip-off is that the photograph in the Ebay auction will be dark or out of focus, so it’s hard to tell if the radio is the modified version or not.

It has become quite rare to find an original SONY modification kit, which includes a new top cabinet of the SW-100. And some sellers are trying to get as much as $300 for these, though they rarely sell at this level.

This repair kit was on eBay at time of posting.

ICF-SW100 modification kit found on eBay at time of posting.

It’s also becoming rare to see SW-100S radios new-in-box. I had two of these, sold one and kept the other.

If you’re after one of these marvel radios, do what everyone should do when considering items on Ebay — ask many questions about [the] cosmetic condition, accessories, serial numbers, etc.

Universal Radio, a trustworthy seller I know, had fully disclosed the model number and problems with this radio, so I knew exactly what I was buying. Dan has a very good point, though: unless you know the seller to be honest, do your research and ask questions!

The ailing ICF-SW100

Vlado discovers the faulty ribbon cable (click to enlarge)

Back to my ailing unit: Vlado delivered the news about the ribbon cable via text message, and though I was well aware that the chances were high that was the ribbon cable, I was a little bummed, to say the least, to get the formal diagnosis.

Why? As Dan mentions above, you’ll find that the SW-100S upgrade kit Sony produced in the 1990s is no longer available new; sellers typically list these kits at prices in excess of $300 US. Out of my budget.

But Vlado, ever the intrepid engineer, had no idea I would be disappointed with this news; he was just giving me this FYI via text. Indeed, he seemed entirely unfazed, as in, hey, no serious internal damage here…

Another hour passed. Then came another message from Vlad; this one simply said: “Call me.”

Oh no, I thought. But I called, and Vlado answered cheerfully, “Hello? Tom, is that you? Sorry, I can’t hear you very well because your SW100 is playing too loudly. Hang on–let me turn the volume down!”

Vlad installs the replacement ribbon cable (click to enlarge)

“What!?!” I responded, in utter disbelief.

Yes, he’d got it working! It seems that Vlad had unearthed an old DVD player in his garage that he’d kept merely for parts. He opened it up, identified a ribbon cable with the right pitch, then cut and folded the cable to fit into the SW100. Ingenious!

That’s Vlado for you!

And should I be interested in replacing this used cable with a new one–or in repairing other Sonys–Vlad directed me to eBay listings for new cables which only total about $20, shipped. Truthfully, I’m in no hurry, as this one is functioning perfectly and changing out the ribbon cable seems to have no effect on stored memories, etc. With a single affordable eBay purchase of multiple cable sets, it occurred to me that Vlad would have enough replacement cables to repair the SW100 many times over…

So I bought the cables. (This one for the narrow cable and this one for the wider one.)

My “new” Sony ICF-SW100

Needless to say, I’m very pleased with my “new” (to me) SW100. It’s a little masterpiece of receiver engineering in such a tiny package. And since the ICF-SW100 is unquestionably the smallest portable I own–and is one of the few I own with a proper line-out jack–it may very well become my go-to radio for one bag travel.

It’s in the bag: listening to the ‘SW100 before I pack it for my next trip!

Stay tuned the review…

Vlado’s radio E.R.: the doctor is in

As I’ve said, Vlad is one of the most adept repair technicians I’ve ever known. At my prompting, he’s kindly agreed to let me promote his services here on the SWLing Post. Vlad acknowledges that he “likes a challenge,” adding that he enjoys nothing more than making repairs even when”parts are scarce” and radio”surgery” is required. Moreover, his bench fees will be quite reasonable, especially considering what you receive: new life for a failing radio. So, if you’ve got an ailing rig on your hands, and don’t mind waiting for Vlad to get to it, send it to his radio emergency room, where radios (like my Sony) have life breathed back into them once again.

Long live the Sony ICF-SW100! And long live Dr. Vlado, who makes this possible with his creative (and nearly miraculous) repairs.

To contact Vlad, simply contact me with a description of your radio and its problem and I’ll put you in touch with Vlado.

Guest Post: Richard tests the frequency stability of the Tecsun PL-880

Many thanks to SWLing Post contributor, Richard Langley, for the following guest post:

Frequency Stability of My Tecsun PL-880

Recently, while recording the audio on a particular SW frequency unattended over night, I decided to set my Tecsun PL-880 in USB mode with the 3.5 kHz RF bandwidth setting as I had previously noticed splatter QRM from a station 10 kHz below my frequency of interest. I adjusted the frequency to the nearest 10 Hz for natural-sounding voice. On playing the recording, I was disappointed to find that the signal had drifted in frequency and although speech was still recognizable, music was distorted.

I decided to try to measure the stability of the receiver by recording the Canadian time signal station CHU on 7850.00 kHz in USB mode (CHU has no LSB component) over night for over nine hours. The receiver was operated with just its telescopic whip antenna indoors and the audio was recorded with a Tecsun ICR-100 radio recorder / digital audio player. I wrote a Python script to compute the audio spectrum of each one-minute segment of the recorded files using a fast Fourier transform (after removing a DC component). The script then looks for the largest peaks in the spectra centred on a specified frequency and prints out the frequency (to the nearest Hz) and amplitude of the peak. In case the signal has dropped below audibility, a threshold is set and if the detected peak is below the threshold (likely just detecting the random noise background), it is skipped. The specific centre frequency I was looking for was 1000 Hz, the frequency of the tone used to mark each second of the CHU broadcast except when the voice announcement and digital signal are transmitted. In AM mode, the spectrum would consistently show a peak at 1000 Hz but in SSB mode, the peak will vary depending on the receiver frequency setting and the actual frequency of the receiver’s oscillator.

The plot below shows the received CHU one-second tone frequency as a function of time (UTC) from when the receiver was first switched on.

StabilityPlot-CHU1000hz

It shows the tone frequency started out at about 1046 Hz slowly dropping in the first half hour to about 1012 Hz and after about an hour stabilized to 1011 Hz ± 1 Hz for the better part of an hour. (This shows that you may have to allow a receiver to “warm up” for perhaps up to an hour before attempting anything close to accurate frequency reading at the order of 10 Hz.) But then, over the course of the next seven hours when the signal was audible, the frequency slowly rose ending up at about 1034 Hz. The variation might be affected by the ambient air temperature (but this should have been nearly constant), air flow around the receiver, and perhaps the charge level of the receiver’s battery. On several occasions, I have turned the receiver on (after being off for many hours) and seen a CHU frequency offset of only 10 or 20 Hz. So, I intend to repeat this experiment sometime to check on the day-to-day frequency stability. This frequency stability measurement technique could also be used with WWV/WWVH by recording the 440, 500, or 600 Hz tones broadcast at different times during the broadcast hour.

Of course, it’s also possible to check the receiver’s frequency offset in real time by switching between AM and SSB modes while adjusting the receiver frequency in 10 Hz steps until the signal sounds the same in both modes. There is also freely available computer software for various operating systems that can display a real-time spectrum of audio passed to it through a microphone or line input. So, a CHU or WWV/WWVH test using such software could also be performed in real time. And alternatively, by tuning say exactly 1 kHz away from the transmitted carrier frequency in SSB mode, the software can be used to measure the audible heterodyne frequency to better than 10 Hz — even 1 Hz. This frequency can then be added or subtracted as appropriate to the dial reading (assumed accurate or with a noted offset) to get the exact transmitted carrier frequency.

By the way, it is possible to calibrate and reset the PL-880 using the procedure documented on the SWLing Post (click here to view).

As a side benefit of the analysis I carried out, we can also look at the quality of the received signal over the recorded interval. In this case, it is a measure of the level of a particular audio frequency rather than the RF signal+noise level we usually get from the receiver S-meter or other signal strength display. This is illustrated in the plot below for the CHU recording. As you can see, reception was mostly quite good between about 02:00 and 04:00 UTC and then became fair but above threshold level until about 05:30 UTC.

The signal was then essentially inaudible up to about 08:00 UTC when with bouts of fading it became audible again for an hour or two with sunrise approaching.

Dr. Phil’s radio articles: portable SDR and pocket DX

5 Replies

SWLing Post reader, Dr. Phil, recently contacted me regarding a collection of articles he’s written about DXing and radio modifications.

His site actually has a number of useful articles that I’ll plan to convert to future posts, with his permission.

I asked Dr. Phil for links to two of his most popular publications. He replied:

My two big recent articles are shown below. One is about “Pocket Radio DX”: using under-$20 radios to DX (started in 2003). Click here to download as a PDF.

The other is about using an $18 NooElec TV-tuner as a MW and shortwave receiver. Click here to download as a PDF.

Brilliant! Thanks so much for sharing these, Dr. Phil!

I actually have a Sony ICF-S10MK2, which I consider to be a capable and useful little AM/FM receiver for the sub $20 price. I’ve also been very tempted to purchase an RTL-SDR dongle, so I may go ahead and bite the bullet on one of the NooElec SDR dongles.

The Radio Broadcaster Who Fought the Cold War Abroad but Remained Unheard at Home

By DOUG RAMSEY

During the Cold War, listeners in captive nations behind the Iron Curtain huddled around radios in basements and attics listening to the imposing bass-baritone voice of the man who sent them American music. His greeting—“Good evening, Willis Conover in Washington, D.C., with Music U.S.A.”—was familiar to millions around the world. At home, relatively few people knew him or his work. A proposal for a postage stamp honoring Conover may give hope to those who want the late Voice of America broadcaster to be awarded a larger mark of distinction.

For 40 years, until shortly before his death in 1996, Conover’s shortwave broadcasts on the Voice of America constituted one of his country’s most effective instruments of cultural diplomacy. Never a government employee, to maintain his independence he worked as a freelance contractor. With knowledge, taste, dignity and no tinge of politics, he introduced his listeners to jazz and American popular music. He interviewed virtually every prominent jazz figure of the second half of the 20th century. His use of the VOA’s “special English”—simple vocabulary and structures spoken at a slow tempo—made him, in effect, a teacher of the language to his listeners.

Countless musicians from former Iron Curtain countries have credited Conover with attracting them to jazz, among them the Czech bassists George Mraz and Miroslav Vitous, the Cuban saxophonist and clarinetist Paquito D’Rivera and the Russian trumpeter Valery Ponomarev. On the Conover Facebook page established in 2010, Ponomarev wrote that Conover had done as much for jazz “as Art Blakey, Duke Ellington, Horace Silver, Count Basie, Charlie Parker, Miles Davis and Dizzy Gillespie.” Conover’s New York Times obituary said, “In the long struggle between the forces of Communism and democracy, Mr. Conover, who went on the air in 1955 . . . proved more effective than a fleet of B-29’s.” In his publication Gene Lees Jazzletter, the influential critic wrote, “Willis Conover did more to crumble the Berlin Wall and bring about the collapse of the Soviet Empire than all the Cold War presidents put together.”[…]

Regular SWLing Post readers know that I’m a huge fan of Willis Conover. Much like VOA’s Leo Sarkisian, Conover represented some of the best diplomacy this country has had to offer. [I’ve actually had the honor of meeting and interviewing Leo Sarkisian at his home in Maryland, a few years ago–one of the highlights of my career.]

Are there any SWLing Post readers out there who listened to Willis Conover from behind the “Iron Curtain?” Please comment!

Radio Cook Islands

In 1993 I was fortunate to have the opportunity to visit Rarotonga with my wife, courtesy of a nice award through my company which afforded me an all-expenses-paid trip anywhere we’d like to go.

I chose the South Pacific island of Rarotonga, partly because I wanted to visit Radio Cook Islands after listening to their “island music” on 11760 and 15170 kHz through my teenage years.

During our visit to the island I recorded 90+ minutes of RCI on 630 kHz with a local quality signal using a Grundig Satellit 500 and a Marantz PMD-221 recorder.

Recordings

The programming of Radio Cook Islands is bilingual, and announcers are fluent in both English and Cook Islands Maori. Music selections on RCI encompass all styles, to appeal to many age groups. These recordings was scheduled to include as much local music as possible.

RCI programming includes all the hallmarks of a small, non-professional station: stuck records & tape carts, dead air, poor modulation, and other miscues.

However, that’s part of the flavor of local radio, and these errors are heard throughout this recording. Particularly noticeable is the bassy, over-modulation of the studio announcer during sign-on announcements.

Recording 1

Notes: National anthem & hymn; sign-on announcements & music.
Music; weather; sign-off announcements & national anthem.
Local & regional news; weather; ads; music.

Recording 2

Notes: “Party Time” music request show; weather; local ads; more music.

Sadly, RCI will likely never be on shortwave again; a fire in the local tele-comm building a few months before my 1993 visit destroyed RCI’s transmitter. I had an amusing exchange with the secretary when I visited; she insisted that their station was still on shortwave. Of COURSE we’re on the air she said, because “the frequencies are published right here in the newspaper!” The engineer and announcer confirmed, though, that the silence on their former frequencies was for real. They indicated they were covering the outer islands just fine with FM translators and had no intention of restarting shortwave.

RCI’s headquarters is in downtown Avarua, and their 5 kw transmitter (reported at half power, 2.5 kw in Dec. 2012) and modern quarter-wavelength vertical antenna is located in the town of Matavera (northeast side of Rarotonga).

Bing.com maps view of Radio Cook Islands antenna, 630 kHz at Takitumu Primary School, Matavera.

The antenna is in the yard of Takitumu primary school; see photos from Bing Maps and Panaromio [above].

It sure brings back a flood of good memories when I listen to these MP3s! I’d love to visit the Cooks again sometime.

Many thanks for this wonderful stroll down memory lane, Guy–radio nostalgia at its best!

I, too, would love to visit the Cook Islands someday–it is on my bucket list. In the meantime, I’ll enjoy your recordings. Again, many thanks for your guest post!

Virtual Radio Challenge III: Thru-hiking the Appalachian Trail

2 Replies

The Franconia Ridge, a section of the Appalachian Trail. (Photo source: Paulbalegend at en.wikipedia)

On this blog, I often write about selecting the “right” radio for home, boating, preparedness, off-grid living, or, of course, travel. As a result, sometimes I like to go through the mental exercise of imagining a scenario that might be, well, a touch extreme.

After all, as I’ve often said, SWLers come from such interesting walks–even hikes–of life, and often pose the most intriguing questions.

Indeed, I occasionally receive rather “extreme” questions from our readers, questions that push the limits of the hobby in the most exhilarating way, demanding highly specific needs in a radio. And (I readily admit) I thoroughly enjoy these questions. Such queries give me a chance–and good excuse, really–to be imaginative and innovative, to push beyond mere practical or monetary constraints to consider unique environments, weather conditions, durability needs, power requirements, and/or resource availability…all great fun.

If you enjoy this kind of brain game, too, check out our virtual challenge that follows–and, oh, and did I mention…

This time, there’s a prize

The CountyComm GP5/SSB

Dennis Blanchard (K1YPP), Appalachian Trail thru-hiker and author of Three Hundred Zeroes, which chronicles his adventures on the trail, will select his favorite entry in this reader challenge, and Universal Radio will reward the entrant with a new CountyComm GP5/SSB portable receiver! Woot!

So, should you agree to take it on, you’ll need to complete and submit your entry by August 8, 2015 at 06:00 UTC.

Thru-hiking the Appalachian Trail

[This scenario is based on an actual reader question.]

Virtual Location: The Appalachian Trail

Accommodation? Tents, hammocks, and lean-tos on the trail; occasional hotel or hiker guest houses

Electricity? Other than rest days, you’ll be completely off-the-grid

Internet? You can choose to carry a smart phone with you on this hike. Since most of the trail is in rural, remote areas, Internet access will be sporadic on your journey.

Your budget? $300 US must cover all of your radio requirements (radio, antenna, batteries, battery chargers, and all accessories)

Your radio(s)–??? You’re searching for portable radio gear that can receive shortwave, AM (medium wave), and FM. You’ll also need NOAA weather radio functionality to help you plan each day on the trail and make accommodations for frequent spring and summer thunderstorms (and occasional spring snow or sleet).

Virtual scenario: Imagine you’re a recently-retired stockbroker fulfilling a lifelong dream of thru-hiking the Appalachian Trail. You have cleared out most of the year for uninterrupted hiking, starting in Georgia and ending in Maine. You’re covering all of your logistics, travel, and living expenses while on the trail.

Being an avid shortwave radio listener, you see this hike as an opportunity to spend quality time listening to radio–while hiking and camping–in remote areas that are completely removed from urban radio interference you experience at home.

Although you’re looking forward to “unplugging” from the world of stock trading, you’re still keen on listening to international and local news so you’ll know what’s happening in the world of finance and business.

It goes without saying that you’ll carry all of your supplies–your food, camping supplies, clothing, etc.–and all on your back. Minimizing your backpack weight is clearly of utmost importance.

Limitations

Rather than making this virtual challenge more restrictive, these limitations are designed to make the challenge more fun and set a level playing field for all respondents.

Again, you’re limited to a (virtual) budget of $300 US to procure your supplies; ideally, this includes shipping costs of the purchase
You can select new, used or homebrew/kit gear, but must base your choices on reality (i.e., actually find item(s) online and document the price and time of availability). If you “shop” eBay, make sure you’re using the final purchase price, not the current or opening bid. If you do locate something used on eBay, QTH.com, QRZ.com or at Universal Radio, for example, include the link! (Just to add to the fun.) If you enter a homebrew radio, it should be based on something you’ve either built or used and must include a photo. Of course, you can use multiple radios, but keep in mind the amount of space and weight these will take up in your backpack.
Your main objective is to listen to international and local broadcasters and NOAA weather radio. If you’re a ham radio operator, by all means, you’re invited to include a transceiver in your trail kit (indeed, many do have AM/FM/SW reception), but keep in mind that our accomplished A.T. thru-hiker judge will base his decision on the best set up for listening to NOAA weather radio and international, local and broadcasters.
Remember, you’ll be stuck with this radio once you hit the trail! So choose something you’ll love to operate, and don’t forget your vital accessories. Note that there are many points of the Appalachian Trail that are in proximity to towns and cities; you can get additional supplies there as needed.

About the Appalachian Trail…

If you’re not familiar with the Appalachian Trail, you’ll find a wealth of information about it at the Appalachian Trail Conservancy’s (ATC) website. The following is an ATC description of the trail:

The Appalachian Trail is one of the longest continuously marked footpaths in the world, measuring roughly 2,180 miles in length. The Trail goes through fourteen states along the crests and valleys of the Appalachian mountain range from the southern terminus at Springer Mountain, Georgia, to the Trail’s northern terminus at Katahdin, Maine.

Known as the “A.T.,” it has been estimated that 2-3 million people visit the Trail every year and about 1,800–2,000 people attempt to “thru-hike” the Trail. People from across the globe are drawn to the A.T. for a variety of reasons: to reconnect with nature, to escape the stress of city life, to meet new people or deepen old friendships, or to experience a simpler life.[…]

FUN FACTS

The Trail is roughly 2,180 miles long, passing through 14 states.

Thousands of volunteers contribute roughly 220,000 hours to the A.T. every year.

More than 250 three-sided shelters exist along the Trail.

Virginia is home to the most miles of the Trail (about 550), while West Virginia is home to the least (about 4).

Maryland and West Virginia are the easiest states to hike; New Hampshire and Maine are the hardest.

The total elevation gain of hiking the entire A.T. is equivalent to climbing Mt. Everest 16 times.

The A.T. is home to an impressive diversity of plants and animals. Some animals you may see include black bears, moose, porcupines, snakes, woodpeckers, and salamanders.

Some plants you may encounter include jack-in-the-pulpit, skunk cabbage, and flame azalea.

HIKERS

About 2 to 3 million visitors walk a portion of the A.T. each year.

The A.T. has hundreds of access points and is within a few hours drive of millions of Americans, making it a popular destination for day-hikers.

“Thru-hikers” walk the entire Trail in a continuous journey. “Section-hikers” piece the entire Trail together over years.

“Flip-floppers” thru-hike the entire Trail in discontinuous sections to avoid crowds, extremes in weather, or start on easier terrain.

1 in 4 who attempt a thru-hike successfully completes the journey

Most thru-hikers walk north, starting in Georgia in spring and finishing in Maine in fall, taking an average of 6 months.

Foods high in calories and low in water weight, such as Snickers bars and Ramen Noodles, are popular with backpackers, who can burn up to 6,000 calories a day.

You’ll want to do your research before choosing gear for the Appalachian Trail Virtual Challenge! The more thought you’ve put behind your choices, the more likely your entry will be selected by our judge. Speaking of which…

Dennis Blanchard (K1YPP) is uniquely qualified for this challenge since he thru-hiked (which is to say, hiked in entirety) the Appalachian Trail in 2007, and carried at least one radio with him on much of the trip. He understands the advantages and limitations of operating from the trail. If you have no concept what it would be like to plan for and hike the trail, you might consider checking out his interesting and informative book, Three Hundred Zeroes, which chronicles his adventures on the trail. Dennis has kindly agreed to pick his favorite entry from reader responses. Click here to read an interview I posted with Dennis on my ham radio blog, QRPer.com.

The selection process

Once our A. T. reader challenge closes on August 8, 2015, I’ll share all the entries with our kind judge. Depending upon the number of responses, of course, Dennis should have a favorite picked within one to two weeks of the challenge’s close. We’ll announce the winner here on the SWLing Post, and shortly after, Universal Radio will reward the selected entrant with the new CountyComm GP5/SSB!

And note…we’ll also share a number of stand-out entries here with our readers!

If you wish to enter this reader challenge, please use the form below to submit your entry (or click here for the form). Entries must be received by August 8, 2015.

Good luck and have fun!

James’ vintage transistor radio collection

23 Replies

In response to my recent post about the vintage Arvin 68R58 transistor radio, SWLing Post reader, James Patterson, has shared photos of his collection in New Zealand. James has captioned each photo below:

This portable Sanyo was bought at a “Second Hand” shop. It had badly corroded battery connections. I repaired it and it works fine now.

Very early National portable with twin speakers, broadcast [band] and [shortwave. Works very well.

This PYE Caddy was actually made here in New Zealand. I believe the design was from the UK though. It still works very well.

The PYE Caddy without the plastic cover.

Very popular in their day, the RED National Panasonic pocket AM Transistor 6. Works well.

Very early AIWA pocket Transistor 6. Still works well.

The “Murphy 8” Transistor radio. Broadcast band only. Wooden case in fab condition. Works very well.

This is the rear view of the “Murphy Transistor 8.” I gave it a new battery holder.

This is a “Murphy Transistor 7+” Im not sure what the “+” means because it does have only 7 transistors. Very good performer for its age. Wooden case is identical to the previous Murphy 8.

This is the rear view of the “Murphy Transistor 7 plus.” All very original, and works fine.

This National Panasonic DR 28 is not part of my early AM Transistor radio collection. It is, however, part of my shortwave radio collection.

Many thanks, James, for sharing photos from your collection! You certainly have some gems in there. I was not at all familiar with the New Zealand-made PYE Caddy, in fact. I’m curious if other radios were made in New Zealand in the past.

I bet you and I might agree that the Panasonic DR-28 (a.k.a. RF-2800 in North America) hardly feels “vintage,” but at 37 years old it certainly qualifies by most standards–hard to believe. The RF-2800 pops up on eBay quite often and has certainly held its value well. (Click here to search.)

Seeing the DR-28/RF-2800, in fact, is making me lust even more after the venerable Panasonic RF-2200! Alas…so many radios!
