Zimbabwe: are shortwave radios now illegal?

Analog Radio DialAccording to SW Radio Africa, it appears that shortwave radios could now be considered “illegal communicating devices” in Zimbabwe:

Police have announced a ban on ‘specially designed radios’ that are ‘not compatible with state owned stations’, claiming the devices would be used to communicate hate speech ahead of polls scheduled for this year.

In a move seen as an attempt to silence external radio stations, such as SW Radio Africa and VOA’s Studio 7, broadcasting to Zimbabwe via shortwave and medium wave, police spokesperson Charity Charamba threatened to deal with organizations that helped to distribute portable radios, saying recipients would also be arrested.

She told journalists at a press conference in Harare on Tuesday: “We have information that some people or political parties are engaging in illegal activities, that is to say they are distributing illegal communicating devices to unsuspecting members of the public.

“We strongly believe that the intentions of such people are not holy but meant to create and sow seeds of disharmony within the country, especially now that the country is about to embark on the referendum and harmonised elections.”

The shocking news comes as police upped their onslaught on civil society organization looking for subversive material, gadgets and recordings.

[…]Co-Home Affairs Minister Teresa Makoni revealed [..]that […] receivers only, without ability to transmit, are perfectly legal and that there is no law at present which disallows anyone donating radios to the public.

However the minister said she held lengthy discussions with Police Commissioner General Augustine Chihuri, who said he is concerned that NGOs always intensify distribution just before elections.

Makon[i] said: “I was very clear that airwaves are still restricted to other parties, that is why my party is distributing radios to our poor rural members…in the meantime he will have his engineers verify that the radios are simple receivers.”

Observers say this response ignores the fact that there is likely to be massive intimidation as the average police officer will not know the difference between a receiver and two-way radio communicators.

Shortwave Radio Recordings: Radio Australia, Jazz Notes

This Jazz Notes starts with a performance of "evidence" by  Thelonius Monk

This week’s Jazz Notes starts with the Thelonious Monk song”Evidence” interpreted by the Blaine Whitaker Group (Photo source: Ohio University)

This morning at 13:30 UTC, I enjoyed listening to 11,945 kHz, home of Radio Australia and their Wednesday music show, Jazz Notes. I recently posted a recording of Jazz Notes and described my fondness for this particular show. Moreover, I find that the sonic texture of the shortwave ether enhances the nostalgic character of one my very favorite music genres.

As on most mornings, the signal out of Shepparton, Australia, on 11,945 kHz was very strong; the audio fidelity was, in consequence, very impressive for a transmission emanating from some 9,800 miles away.

Pirate Radio Recordings: WMPR

RadioListening

“Mama, they’re playing your favorite dance music!”

For your listening pleasure: 32 minutes of pirate radio station, WMPR.

I recorded this broadcast of WMPR on 6.925MHz AM on February 17th, 2013 at 10:00 UTC. You’ll note that this recording sounds a little “brighter” than a typical shortwave radio recording.  This is due to the fact that I widened the AM filter to match the bandwidth of WMPR’s signal (about 17 kHz!).

Trevor Baylis, inventor of the wind-up radio, fights for patent rights

The Telegraph reports that British inventor Trevor Baylis, now 75, who created the first wind-up radio, is unfortunately struggling with patent laws in the UK. The eccentric gentleman (Trevor, I mean this as a compliment) cites the lack of government protection for inventors’ rights in Britain; unlike in the US and other countries, where patent theft is considered a criminal offense, in the UK it is merely a civil one.  Meanwhile, Bayliss, who has received many honorary degrees for his work, and an OBE from the Prince of Wales, is currently in a bit of a financial struggle.

This is sad.  Radio truly owes Trevor Baylis a great debt of gratitude; his invention spawned an era of self-powered technologies such as those we use at Ears To Our World, that have brought life-saving information and lighting to the most rural, remote parts of the world.  He has truly made a difference to people’s lives, especially where there’s no reliable access to electricity.

I still keep an original BayGen radio at my house, just like the one Baylis is pictured with above. It’s an amazing invention, indeed–loud, clear, room-filling shortwave audio from a radio that doesn’t require batteries; only a little winding, as simple as winding your wrist watch, delivers this remarkable sound.

The Telegraph tells the evolution of the BayGen radio into the Freeplay radio, and then Bayliss’ loss of revenue as the original patent for the clockwork radio was not honored when Freeplay began using the same mechanism, with a modification, to charge an internal battery. Ironically, Freeplay spawned The Freeplay Foundation, now known as Lifeline Energy,  a worthy organization with the goal of helping others.  And obviously, Baylis is not financial guru:  he did sell his shares in Freeplay and parted ways with the organization over a decade ago.

But to be fair, Baylis is an inventor, not a businessman.  I can see his side of the argument:  if you wish to build your life around inventing, your creations and intellectual property need to be properly protected. It should not require another degree–or another full time job–simply to protect your ideas.  If Baylis’ inventions had been properly guarded, he would probably still be churning out inventions at age 75 instead of fighting to keep his house and to protect other inventors from the same fate. Baylis–and The Telegraph, in turn–are placing the focus on beefing-up the patent laws in the UK to help protect innovations. In Baylis’ case, I believe it may be a lack of international protection that has had an effect on his bottom line.

How can we help Trevor Baylis?  We’re determined to find a way.  Stay tuned…

A review of the Degen DE32 shortwave radio: compared with the DE321 and Tecsun PL-380

The Degen DE32 (Click to enlarge)

The Degen DE32 (Click to enlarge)

The Degen DE32 is one of the latest DSP-based analog radios to hit the market. In the past, I have reviewed two others: the Degen DE321 and the Kchibo KK-9803. Tecsun had announced a version of their own–the Tecsun R-2010–which I had eagerly anticipated, but I now believe it’s been dropped from their future offerings. [Update: Not true–the Tecsun has been released as the R-2010D, see review].

I purchased my Degen DE32 from this China-based seller on eBay. To my knowledge, eBay is the only place the DE32 can be purchased, at time of posting. As with the other radios mentioned above, my expectations were quite low for this little radio.  After all, at $27 US (shipped), you can’t expect top-notch performance characteristics.

IMG_5886

The DE32 un-boxed (Click to enlarge)

The DE32 comes with a carry strap, USB cable, a carry pouch, slim rechargeable battery, and operating instructions in Chinese. It does not come with a USB wall adapter (you’ll have to plug it into a USB port on your PC or other USB wall charger) and it does not come with a Micro SD card (for digital audio playback).

Audio

The DE32 has a small built-in speaker. The sound is a bit tinny, but is actually better than I expected from a speaker of this size. It makes for comfortable listening at close range–especially of spoken-word broadcasts. Happily, plugging in a good set of earphones helps audio fidelity tremendously.  This is the only way I would listen to music on the DE32 for an extended period of time. On FM, in fact, audio via earphones is surprisingly good (again, for a $27 radio–check out the audio sample below).

(Click to enlarge)

Performance

The DE32 covers three radio bands: medium wave (AM), FM and shortwave (5.6-22 MHz). Performance between bands varies greatly. The best band, by far, is FM. Again, no surprise here, as the DE321 and KK-9803 performed quite well on FM.

Here’s a 20+ minute audio sample of a local classic rock radio station I recorded, 95.7FM The Ride:

From my home, I can pick up my benchmark distant NPR station quite easily if I hold the radio in my hand. If I place the radio in a window sill, its performance degrades somewhat and contains more static as the extra grounding (from holding the radio) made a positive difference. The audio, though, is still perfectly intelligible. Local FM stations come in quite clear and fidelity (through headphones) is excellent.

The Degen DE321 (left) and DE32 (right)

I found that strong local medium wave (AM) stations sound quite good on the DE32–better than its cousin, the DE321, by a small margin.

While traveling over the holidays in December, I recorded extended samples of local station (630AM WAIZ) with both the DE32 and the DE321. You can listen to audio samples below, but first it’s important to note that I recorded these (and the FM sample above) with my Zoom H2N digital audio recorder, with radios at a comparable volume and via an audio patch cord.

Note that these recordings represent what each radio sounds like via headphones, not their internal speakers.

This is WAIZ on the Degen DE32:

Compared with WAIZ on the Degen DE321:

You’ll note that the DE32 sounds a little fuller than the DE321, but reception is nearly identical on this local strong medium wave (AM) station. I also found that the DE32 was quite effective at nulling out local RFI (electrical noises) on medium wave. At the beginning of the recordings, above, you’ll hear the static increase and fade as I null out the noise by turning the body of the radio. The DE321 couldn’t null out the local noise quite as effectively as the DE32.

For medium wave DXing, though, you’re better off finding a different ultralight radio. The AGC simply can’t handle marginal signals. Indeed, the same AGC problems plague the shortwave bands as well. DXing would be very unpleasant as the AGC circuit simply can’t cope with weak signals or fading.  All in all, as with medium wave, shortwave radio reception is fine for most strong signals.

Tecsun PL-380: What a difference an extra $23 makes

On shortwave, I decided to also compare the DE32 ($27) to the Tecsun PL-380 ($50). I tuned to a Radio Australia broadcast on 11,945 kHz. The comparison between these three portables is interesting:

First, the Degen DE32:

Now, the DE321:

Both the DE32 and DE321 struggled to receive the Radio Australia signal. In fact, if you really wanted to hear those broadcasts and had to listen on either radio for 30+ minutes  it would be frustrating and fatiguing. Notice, however, the difference when listening to the same broadcast with the Tecsun PL-380:

The Tecsun PL-380 receives circles around the DE32 and DE321 on shortwave and medium wave

There’s no comparison, really. In other words, you can hear it. The PL-380 has a lower noise floor, a fuller sound and no AGC problems as with the DE32 and DE321.  Hence the reason I always take the PL-380 while travelling–and as a back-up if I plan to record a broadcast on-the-go.

On the shortwaves, as with medium wave, the DE32 is respectable when tuned to a strong signal. For comparison to the weaker signals above, here is a short recording of the DE32 tuned to Radio Havana Cuba:

Not too bad, really. Keep in mind, though, that in my part of North America, Radio Havana broadcasts are so strong that I can pick them up without even extending the whip antenna on most portables.

Conclusion:

I haven’t tested the digital audio playback on the DE32 yet, although I expect the audio to be pleasant enough.  Of course, it lacks a display to show any information about the audio you’re playing, but it would be great to load a few podcasts or audio books on.

In summary, I’ve tabulated the pros and cons below from the moment I took the DE32 out of the box, below. Note that these pros and cons take into account the $27 price level of this radio:

Pros:

  • Very portable and lightweight
  • With micro SD card, storage for hours of pre-recorded content (though not tested in this review)
  • Adequate shortwave coverage (5.6 to 22 MHz) (see con)
  • Good audio fidelity, via headphones, on strong stations, slightly better than the DE321
  • Above average FM reception
  • Great nulling ability on medium wave (AM)
  • Features a built-in LED light (see con)
  • Overall build quality seems to be acceptable
  • Standard analog volume control (not digitally incremented levels)
  • Red LED tune light (see con)

Cons:

  • Shortwave sensitivity and selectivity are poor
  • Shortwave coverage lacks the lower tropic bands
  • Bandwidth is not adjustable and too broad for crowded conditions
  • AGC (as with many DSP portables in this class) cannot deal with weaker DX stations
  • Medium wave (AM) imaging on the shortwave bands if strong local station present
  • Antenna slightly loose in antenna hole when fully extended
  • No battery level indicator
  • No back stand
  • Tinny sound from tiny built-in speaker
  • To operate LED flashlight, you must press a button continuously to keep illuminated and LED  bulb orientation does not help with reading display in dark (see pro)
  • No option for standard AA or AA batteries–only included li-ion rechargeable pack
  • LED tuning light only works with very strong stations (see pro)
Conclusion? Though slim, lightweight and inexpensive,  I wouldn't find the DE32 DSP radio/digital audio player a useful radio in my collection.

Conclusion? Though slim, lightweight and inexpensive, I wouldn’t find the DE32 DSP radio/digital audio player a useful radio in my collection.

If I were you, would I buy it?

If you’re looking for a very inexpensive MP3/Digital Audio player with AM/FM and shortwave, and your expectations are fairly low, the Degen DE32 is a reasonable $27 piece of kit. Especially if you only plan to use the FM band.

If the digital audio playback abilities are not important to you, I would go with the cheaper ($18 US) Degen DE321.

But if you really want performance on medium wave and shortwave, and you could care less about digital audio playback, spend the extra $23 ($50 total) and buy the Tecsun PL-380, instead.  As you can hear above, it’s a much, much better receiver.

Shortwave Radio Recordings: The Mighty KBC

tom-petty

This episode of The Giant Jukebox features one of my favorites from Tom Petty and the Heartbreakers

The Mighty KBC broadcast again early this morning (from 00:00-02:00 UTC) on 9,450 kHz. Their signal was quite strong into North America and there was very little interference of any sort. As we’ve come to expect, the KBC’s Giant Jukebox of music has a lot of rock-n-roll variety, spanning the decades.

And as I’ve mentioned before, perhaps what I love most about The Mighty KBC is their format; it harkens back to the day when my local radio stations had professional DJ’s behind the mic, people who loved music and loved their job.  Thanks to Eric and The Mighty KBC for blasting the Giant Jukebox across the planet! I look forward to their broadcast every weekend.

You can listen to the full recording below in the embedded player, or simply right click this link and save the MP3 file to your computer:

You’ll notice that Kim Elliott has another installation of digital text modes in this broadcast. At about 01:30 UTC, Olivia 8-2000 will be centered on 1500 Hertz, and PSKR125 centered on 2800 Hertz. At just before 02:00 UTC, images in MFSK32 will be at 1000 and 2000 Hertz, with another image in MFSK16 at 2600 Hertz.
