Guest Post: A visit to Tokyo’s Akihabara district

Many thanks to SWLing Post contributor and word traveler, Chris Johnson, who shares the following:

This past year while traveling for business in Japan I decided to explore a district within the city limits of Tokyo known as Akihabara or better known to locals as the “Electronics District”.

After jumping off the train I found my senses bombarded by a cacophony of sounds and enough neon from the street to the sky to put your senses into overload. The streets were crowded and the stores were filled with every modern electronic device known to man.

Click here to watch video.

My imagination ran wild, I started wondering what this place would have been like in the 1970’s when some of the most cutting edge electronics were CB radios or shortwave receivers, the different brands, models etc… Perhaps some of that still existed here so I started wandering the streets and found more of the same you would find in a big box store but multiplied by 10, overwhelming.

Just when I was ready to give up the search I turned the corner down a side street and discovered a red awning with “Tokyo Radio Department Store” emblazoned on it, I felt like I discovered a lost treasure amongst the modernity.

I walked through the main entrance and was immediately drawn down a maze of narrow corridors that were staffed with small stores and stalls that sold electronic parts both popular and obscure, it was incredible. That was just the first floor with 3 more above to discover, I thought to myself if I ever wanted to build a transmitter this is the one place in the world where you could shop and find all the parts you need.

As I ventured up the narrow stairs to the floors above once again I felt like I found a treasure of gold, before me were shelves and displays crammed full of radios, some I haven’t seen in many years and some from the recent past .

This was like a Hamfest and eBay together under one roof. Truly incredible as you will see in the pictures below. I couldn’t get close to some of the ones wrapped in plastic but maybe a sharp eyed enthusiast can Identify them. I highly recommend anyone traveling to this part of Asia to check out this hidden gem you will not be disappointed.


Thank you so much for sharing this photo tour, Chris! I mean…WOW! There are so many radio gems here. I see some classic solid-state receivers, ham radio transceivers and even valve gear I’ve never seen before. Amazing!

Thank you for taking the time to share your tour of the Akihabara district of Tokyo!

Post readers: Please comment if you’ve ever visited the Akihabara district or any other “Radio Row” districts in the world. please consider sharing your photos!

Any reviews of the JINSERTA Mini portable radio?

Many thanks to SWLing Post contributor, Marc Thomas, who writes:

I was wondering if anyone has tried this $40 receiver that seems to have an exceptionally broad frequency coverage:

SW: 2-30MHZ, 5KHZ STEP
AM: 520-1720, 9K/10K STEP SEL
FM: 87.5-108MHZ, 0.1MHZ STEP
AIR: 118-138MHZ, 5K/50K STEP SEL
VHF: 30-223MHZ, FM-N/FM-W
CB: 25-28MHZ, 5KHZ STEP

Links to several sellers:

Not sure I like the proprietary looking battery.

Thanks.

I am not familiar with this radio, Marc, other than I can see the physical similarities with the Eton Mini. The Eton Mini, however, does not have the VHF coverage of this radio.

Post readers: Is anyone familiar with the JINSERTA Mini? If so, please comment!

75 years ago today: “Christmas Eve at the Front,” a ground-breaking global broadcast

How would Christmas Eve at the Front have sounded on a radio back in 1943?  Something like this…


Christmas Eve, 1943:  America’s third in WWII.

On this day, exactly three-quarters of a century ago, America tuned into a special live broadcast that would not only engage American listeners, but also every major network in the US at the time: CBS, NBC, and Mutual Broadcasting Company.  The simulcast program, “Christmas at the Home Front,” starred troop entertainment veterans Bob Hope and Bing Crosby, as well as numerous others including screen actor Lionel Barrymore–also well-known for his regular portrayal of the miserly Scrooge in NBC’s annual radio drama “A Christmas Carol”–and featured an address by then-President Franklin D. Roosevelt.

This broadcast also included live audio feeds from North Africa, Italy, New Guinea, Guadalcanal, New Caledonia, China, India, Panama, Alaska, Pearl Harbor and even Navy ships in undisclosed locations. Keep in mind, this was 1943. These audio feeds weren’t carried over the Internet or a satellite network, they were shortwave radio signals from remote sites–signals that were bounced off of the ionosphere and back to the studios where they were incorporated in a live radio show.  No doubt, this holiday special required months of planning to orchestrate and perhaps even a leap of faith to execute.

Being something of a WWII radio buff, I’ve listened to this recording a few times in the past. And after receiving Bill’s message about it recently, I listened again; the audio obviously came from a recording at NBC studios, very pristine considering the recording’s age and the number of times it’s likely been copied or changed formats, but also with demarcated track switches, not exactly as it would have sounded on the air at the time.

So I did what any self-respecting radio geek would do: I fed the recording into an AM transmitter to recreate the sound as it might have played on American radios of the time, and made an off-air recording of the entire broadcast.

Hopefully now, with the help of this recording, you may be able to imagine what families on Christmas Eve in 1943, huddled around their radios, might have experienced as they strove to feel a little closer to loved ones serving in the war, while enjoying a little light entertainment and absorbing the latest message from their president.

But it’s also meaningful to note that times have certainly changed since 1943.  Without a doubt, it’s often easy to be lulled into a nostalgic appreciation of that time, and former times generally, made all the rosier by the present knowledge that the outcome of the war was, in many respects, favorable to us.  But those who know history know the truth: that war is hard, that our struggles both here and abroad were real, and that people died–as many as 85 million.  When the drama was over, the fallen did not rise again to play in another film; they were gone, forever.  This is the grim shadow that lies beneath the warmth of entertainment broadcasts like this one.

Fortunately, our civilization continues, and will always view the war and the political circumstances surrounding it through the fading glass of advancing time and hear it through the crackle of increasing distance.  And fortunately, our then-enemies are now among our strongest allies.  We have a diverse and international audience here at the SWLing Post, so I hope this recording is recognized for what it is: simply a moment in entertainment history that the passing of time allows us to enjoy, during a war the likes of which we hope never again casts such a shadow over us.  One such was enough.

Now sit back, close your eyes, and set your time machine’s dial back to Christmas Eve, 1943…

Imagine you’ve just turned on the family console radio, the frequency dial gradually warming with its familiar glow, and have tuned to your local NBC station; soon, the voices of well-known entertainers begin to fill the parlor and the rest of the household, their tasks or play momentarily abandoned, quietly join you there to listen…

Quick Look: the RADIWOW R-108, a new DSP shortwave portable

Last week, I received a new portable shortwave radio by the post from China: the Radiwow R-108.

The brand, Radiwow, was new to me, but I suspect they’re linked in some way to the folks behind XHDATA. They contacted me around the Thanksgiving holiday and inquired about evaluating this new portable receiver. I replied, asking a few questions about the unit–you see, I don’t typically agree to take a look at a new product if I think it could simply be a re-badged version of something currently on the market.

Their reply was simple:

“Yes, it is shortwave radio, like PL-310ET radio but add air band, and better reception performance. Your tracking number is…”

So evidently, it was already on the way.

Radiwow claims the performance is better than that of the venerable Tecsun PL-310ET. This, I will have to test because the PL-310ET is certainly a workhorse Ultralight radio. And the R-108 includes air band? Sounds like a CC Skywave without weather radio. That could be quite appealing if the price is competitive.

And it seems this little radio fits neatly into the requirements of Ultralight DXing, thus I hope Gary DeBock and Guy Atkins might take a look as well.

In addition, the R-108 includes longwave frequencies. Something I know will please a number of our readers.

Here are some of the key points I gleamed from a digital copy of the owner’s manual:

Radiwow R108 Features:

  • Frequency range:
    • Longwave: 150-450 kHz)
    • Mediumwave/AM: 520-1710 kHz w/10 kHz steps, 522-1620 kHz w/9kHz steps
    • Shortwave: 1711-29,999 kHz
    • FM: 87.5-108 and 64-108 MHz
    • AIR: 118-137 MHz
  • ATS memory scans on all bands
  • 500 available preset memories
  • Squelch control
  • Direct keypad entry of frequencies
  • Clock function with sleep timer, snooze and alarm (buzzer or radio)
  • Keylock
  • FM stereo
  • AM bandwidths: 6, 4, 3, 2, and 1 kHz selections
  • Music/Voice audio modes
  • Built-in intelligent charger for included 3.7V 1500 mAh Li-ion battery pack

By the way, I suspect Radiwow is linked to XHDATA because 1.) they knew my shipping address without asking and 2.) their website prominently features the XHDATA D-808.

In addition, the only other place I could find the R-108 listed on the Internet is via AliExpress. As with the introduction of the XHDATA D-808, the AliExress price is (today) absurdly high. To me, this indicates that the page is simply a placeholder until the first production run is ready to ship.

I have a PL-310ET and you can count on me to compare the two sometime after the holidays.

In the meantime, I thought I’d share a few photos of the unit.

I must admit, the front panel of the radio looks familiar, but perhaps only because most other DSP portables have a similar layout. Please comment if you know of an identical portable.

Follow the tag Radiwow R-108 for updates.

WRTH 2019: A look inside

I received my copy of the 2019 World Radio and TV Handbook (WRTH) directly from the publisher earlier this week. It arrives annually–without fail–just prior to my Christmas holiday travels.

I look forward to receiving this excellent staple radio reference guide–and this is their 73rd edition! The WRTH has never disappointed, so my expectations are always quite high.

Once again, the WRTH lived up to my expectations.

WRTH’s team of noted DXers from around the world curate frequencies and broadcaster information by region; while I’m not sure how they orchestrate all of this, the end result is truly a symphony of radio information. In addition to broadcaster listings, WRTH’s radio reviews, feature articles, and annual HF report make for excellent reading.

But the WRTH isn’t just a frequency guide: the publication always devotes the first sixty or so pages to articles relating to various aspects of the radio hobby. Following, I offer a quick overview of these.

The first article always features a WRTH contributor:  this year, they feature Kai Ludwig who is their contributor for Germany. His lifelong passion for international broadcasting started in what was then East Germany–he watched with interest as the broadcasting world change around him as the Iron Curtain fell.

The second set of articles is always my favorite: WRTH receiver reviews.

The AirSpy HF+ SDR

This year, WRTH begins with a review of the WinRadio Excalibur Sigma SDR receiver–which essentially set a new benchmark.  They also review the SDRplay RSPduo, AirSpy HF+ (which truly impressed), the Reuter RDR51 “Pocket” SDR, XHDATA D-808 and the new Icom IC-R30 wideband handheldWhat I love about the WRTH review selection is they span products ranging from £70 all the way up to £6200! Certainly, choices for everyone.

 

The next feature article, written by none other than Dave Porter, focuses on curtain antennas–the true work horses of international broadcasting. His article speaks to the history and theory behind curtains and notes several types often used by international broadcasters. A must-read!

Hans Johnson’s feature, Broadcasting For Peace, tells the inspiring story of how two stations with one mission helped promote peace in a troubled region of Africa. It truly is amazing how these stations gave their listeners a voice and hope.

The following article highlights a broadcaster on the opposite side of the globe: V7AB in the Marshall Islands. For this feature, journalist Mika Mäkeläinen traveled to the Marshall Islands and visited this powerful national AM broadcaster.

Speaking of powerful broadcasters, TWR Broadcast Engineer, Dave Pedersen, authors an article outlining the reasons for and challenges of operating and maintaining TWR’s Bonaire MW transmitting station.

Next, WRTH spotlight the annual Digital Update which summarizes the dynamic state of digital broadcasting. I’ve found this feature to be incredibly informative as we see how digital broadcasting is penetrating both domestic and international services.

The final article–a tradition–is the WRTH  HF propagation report/forecast by Ulf-Peter Hoppe. Always an informative read despite the fact we’re in a solar low!

The 73rd is another fantastic edition of the World Radio TV Handbook. As I say every year, I’ve never been disappointed with WRTH. Their publishing standards are such that the quality of their reviews, their writing, and (most importantly) their broadcast listings are simply unparalleled.

For DXers who collect QSL cards, you’ll find that broadcaster contact information in WRTH is often more up-to-date than a broadcaster’s own website. When readers contact me asking for QSL information from an obscure broadcaster, the first place I search is the current WRTH. Remember: their information is based on volunteer contributors who specialize in specific regions of the world–the most knowledgeable regional DXers keep this publication accurate.

Purchase your copy of WRTH 2019 directly from WRTH’s publishers, or from a distributor like Universal Radio (US), Amazon.com (US), Radio HF (Canada), or check BookDepository.com (International).

Washington State’s Long-lost ‘Magic Radio’ Santa Gets New Life

This is what the announcer said at 4:30 p.m. one day about a week before Christmas 1950 over the airwaves of radio station KELA in Lewis County: “Yes, stand by for Santa Claus! The Beacon Store, Santa’s headquarters for southwest Washington, presents the most important radio program of the year, Santa’s very own. Santa’s Magic Radio! We’re going to take Santa’s Magic Radio and talk to Santa at his North Pole headquarters! So, stand by for Santa Claus!”

First of all, let me be very clear: I believe in Santa Claus. Second, I’m a sucker for grownups who do things to make the lives of kids more magical. When I was a little kid in the 1970s and was in my “doubting Santa” phase, I’d hear local and national media reports about NORAD tracking Santa’s sleigh, and my doubts were instantly – and permanently – erased.

Fast-forward about 40 years, and I learned this week that there were some grownups in Lewis County who did a pretty special thing every year to help Santa and local kids.

For about three weeks before Christmas, from sometime in the 1940s to sometime in the 1980s, radio station KELA in Centralia/Chehalis would use a “Magic Radio” to connect with Santa Claus at the North Pole for 15 minutes each day. With the swirling sounds of a blizzard in the background, and with help from a fast-talking elf named Tommy Tinker, Santa would read letters from local kids about what they wanted for Christmas.
