Leeds Radio featured in the NY Times

(Source: NY Times)

WHEN an insurance company declared the merchandise at Leeds Radio “not pilferable” last year, it meant that the store’s hundreds of thousands of analog electronic parts — all manufactured before 1968 — were unlikely to be stolen anytime soon.

[…]And yet Leeds, one of the oldest electronics stores in the country, has plenty of paying customers. Located at 68 North Seventh Street in Williamsburg, Brooklyn, two blocks from the Bedford Avenue stop of the L train, it attracts a steady stream of musicians, hi-fi aficionados, ham radio buffs and the kind of people who build Tesla coils in their basements.

The 2,500-square-foot space smells like a vintage record shop (an odor Mr. Matthews describes as equal parts phenolic resin, adhesive, old cardboard and wire insulation) and appears shockingly disorganized. Cubist piles of boxes overflow with switches, capacitors, Bakelite knobs and watt meters. The floor glitters with the glass of shattered vacuum tubes.

Sounds like my radio room, though on a much, much larger scale…the part with piles of boxes, at least. Thanks to the Herculodge for leading me to the NY Times article. We actually posted another article about Leeds Radio when it was featured on WNYC. As both articles mention, radio parts shops like Leeds are certainly on the decline [understatement alert]–luckily, the internet opens up a whole world of mom-and-pop vendors like Leeds, though with a virtual store front, so there is still hope.

BBG: Radio audience far exceeds that of TV, internet

(Source: BBG)

(WASHINGTON, D.C.—November 15, 2011) U.S. government funded international broadcasters reached an estimated 187 million people every week in 2011, an increase of 22 million from last year’s figure, according to new audience data being made public by the Broadcasting Board of Governors.

[…]The record numbers, released in the BBG Performance and Accountability Report (PAR), measure the combined audience of the Voice of America (VOA), Radio Free Europe/Radio Liberty (RFE/RL), Radio and TV Martí, Radio Free Asia (RFA) and the Middle East Broadcasting Networks (Alhurra TV and Radio Sawa). The report details impact on audiences around the globe including people in the world’s most repressive media and political environments.

[R]adio remains the BBG’s number one media platform, reaching 106 million people per week, [while] television’s growth puts it at 97 million people. The Internet audience was approximately 10 million, with the largest online audiences measured in Iraq, Russia, Indonesia, Egypt and Iran.

In summary, BBG’s stats show that radio has fully 10 times the audience of the internet/SMS, and radio listeners surpass television viewers by 9 million. Clearly, radio leads the way because it is a basic technology that has been in place for decades, building a lasting infrastructure and audience. We’ve posted numerous articles proving that radio–specifically, shortwave radio–is still a viable and dynamic information medium, with no regard for borders, for the party in power, or for the economic status of the listener.

Indeed, radio is perhaps the only information medium–other than word-of-mouth–that informs both some of the most wealthiest and some of the most impoverished people on our planet.

Let’s keep it alive: remind your broadcasters that radio is a lifeline for many listeners across the planet.

WWII shortwave messages found on cardboard discs

The voices of Canadian servicemen fade in and out, at times clear and booming, at others distant and muffled. But for their families, these scratchy, static-laden messages were the sound of hope.

The men were prisoners captured during the Second World War by the Japanese army, which broadcast their messages home over Radio Tokyo. Short-wave radio enthusiasts on the west coast of the United States listened in, making a hobby of recording the messages onto cardboard discs and sending them to the soldiers’ families.

Complete with audio from the original discs, this is an article you should view in full at The Globe and Mail.

A review of the Degen DE321 DSP shortwave radio

This analog dial packs DSP!

The Degen DE321 is the first of a new type of radio hitting the market–a DSP-based receiver with an analog tuning dial. I was very intrigued by this radio since both it and the future Tecsun R-2010 are the newest of their kind. We’re still waiting for the R-2010 to hit the market, but the DE321 was introduced just a few weeks ago.

So, keep in mind that the DE321 I describe is not technically analog, although the dial and face appear to be.

Impressions

The Degen DE321 is slightly thinner than the Kaito WRX911.

My first impressions of this radio are very positive. The DE321 is small, slim, and fits nicely in the hand. While holding it the first time, I even noticed a small indentation where my index finger fits on the back of the radio underneath the telescoping whip antenna. Nice touch!

The DE321 also feels durable. It’s slightly thinner than the venerable WRX911–the radio I believe it best compares with in the analog world. It’s the first SW radio I’ve owned that can actually comfortably fit into the pocket of my jeans. Indeed, its size and form are fairly comparable to the typical smart phone.

For a very tiny built-in speaker, the DE321 has unexpectedly decent audio. In fact, it is easily superior to the WRX911–its tones are more mellow and there’s even a hint of bass response. I’m sure the DSP chip has been tweaked to produce audio suitable for this application.

The DE321 has a nice, sturdy back stand for tabletop listening. However, it takes quite a lot of pulling force to get it to pop out of its closed position; I keep fearing that I will break the stand when opening it up. For what it’s worth, I prefer this tension to radios that have floppy, lose back stands.

Tuning

The DE321 has a tiny red tuning light that works well when you receive a strong signal.

For a guy who was raised on analog tuning, yet now almost exclusively uses digital portables, the DE321 is a strange animal. When I first started tuning the radio, I noticed that the tuning wheel feels slightly “sticky.” At first, I thought the stickiness of the analog encoder was causing the tuning to skip over stations, as the action was not as fluid as most analog-tuned radios. Upon further investigation, I realized that it’s not the slightly sticky tuning wheel producing the tuning “skips,” rather, it’s the fact that the tuning is actually digital, thus I was hearing the “steps” between frequencies, which tricked my brain, translating into the sensory experience of wheel stickiness. Still, since the tuning wheel isn’t terribly fluid, I am not discounting some real frequency skipping at times.

I’m guessing that the steps are near 5 kHz on the shortwave bands, and that the single bandwidth is rather wide. The tuning steps on medium wave and FM seem to be appropriate for international use.

On a side note, the tuning experience is exactly opposite to that of the Grundig S350DL–an analog-tuned radio with digital display. The S350DL’s tuning feels sloppy and flexible, and the receiver is prone to drifting. The DE321, on the other hand, has a vague analog tuning display, but with precise, incremented tuning behind the scenes.

I’m pleased to note that the DE321’s stability is rock-solid and does not drift.

For casual band scanning, I find that the bandwidth and tuning steps are well placed. Happily, there is no noticeable muting between tuning steps.

Performance

For this review, I compare the DE321 to the analog Kaito WRX911. The two have the same approximate size and price. In the near future, I’ll also compare reception with SiLabs DSP-based radios like the Tecsun R-2010 and the Tecsun PL-380. (Check back for these comparisons soon.)

On the shortwave bands, I feel that the sensitivity and selectivity are well-balanced. When I compare reception with the WRX911, the DE321 seems to pull in faint signals out of the murk a little better than the WRX911. However, I do notice some “pumping” as the AGC tries to cope with faint signals; it reminds me a bit of the Tecsun PL-310 in this respect. Sometimes I also notice that faint signals can range from being very faint to stepping up to clear and strong very quickly–the switch sounds like the DSP moving from not having enough signal to digest, to having enough to do its job. This can be a little frustrating as broadcasts may sound strong one minute, become weak within a fraction of a second, then pop back up again. I only observed this phenomena, however, when processing weak signals. Normal broadcast stations come in quite clearly.

Though I chose not to spend much time evaluating FM and AM (please comment if you have done so), I found the FM and AM (MW) performance to be on par with other radios using the SiLabs DSP chipset. I may expand upon this in the review later. (Update 16 Mar 2012: With more time spent on AM (MW) I realize performance on this band is sub-par–see comments).

Summary

Positives:

  • For a tiny speaker, the sound is surprisingly full
  • Sensitivity and selectivity are both good
  • Nice form–slim, and easily fits in the hand
  • Simple (see negative)
  • Inexpensive
  • Exceptionally wide FM bands (64-108 MHz) (see negative)
  • Unlike its analog counterparts, has absolutely no frequency drift

Negatives:

  • Back stand hard to pop open–though sturdy, it feels vulnerable as a lot of force is needed to open it
  • Tuning wheel feels slightly “sticky”
  • Absolutely no bells and whistles (see positive)
  • FM is in 2 bands, FM 1 and 2 (see positive)
  • AM (MW) performance is very weak
  • Though it looks analog, digital tuning produces slight “stepped” sound/ sensation, unlike the fluid experience of tuning a true analog radio

In conclusion, I think the DE321 is a great buy. It’s certainly a steal at $21 US, shipped. Though I simply find the idea of a rather vague analog encoder and display combined with the precision of a digital tuner a tad quirky–even backward–at the end of the day, the audio is very pleasant and the form perfect for slipping into your pocket.

I’m very eager to see how it stacks up against the soon-to-be-released Tecsun PL-2010.  Stay tuned as I compare these in the near future…

Like most Degen (and Tecsun) radios, the DE321 is only available from eBay sellers in China/Honk Kong. I would normally call this a negative, since there is no real warranty for those of us living outside the country of origin. Still, I’ve been most impressed with purchases I’ve made from these highly-rated sellers. I believe they would help you if a problem were to arise and my experience is that they do a second QC (quality check) of their own, prior to shipping. The Degen DE321 in this review was purchased from eBay seller

Chase some pirates this weekend!

Start your search for pirate radio stations in the watering hole at 6,925 kHz and tune up to 7,000 kHz.

As I sit here in front of my radios this Friday evening, I notice the news on National Geographic that we have one of the largest sun spots to face us since 2005. This sunspot is the size of Jupiter! It’s all a little too coincidental on 11-11-11.

It can only mean one thing…

Turn on your radio and tune in some pirates!

For those of you new to pirate radio, most–but not all–activity can be found between 6,925 – 7,000 kHz (i.e. just below the 40 meter ham radio band). Pirates are not professional broadcasters, thus work  a day job during the week. That’s why you’re most likely to hear pirates Friday, Saturday and Sunday evenings.

Pirate signals are often faint–though perhaps old Sol may help a bit, depending on other conditions. For what it’s worth, I just heard a pirate on my tiny Degen DE321 portable (that review out tomorrow). Very good sign, indeed.  Just in case, consider reading our post on using SSB to help dig pirate signals out of the static.

What are you waiting for? Go chase some pirates!
