Voice of Greece has become a relay of Radio Station of Macedonia, ERT 3

ERT3In response to my post and recording yesterday, TheGreekRadio.com commented on the current state of the Voice of Greece:

“After the forceful eviction of the redundant ERT employees from the Radio House in Athens, the shortwave frequencies no longer transmit the normal program of Voice of Greece as there is no such service produced in Athens.  This happened on the 7th of November, when you probably noticed the station ID change.

Mediumwave and shortwave frequencies have been now set to relay the radio program of “Radio Station of Macedonia” by the redundant employees of ERT3, from Thessaloniki. (This used to be the independent program relayed for a few hours before midnight on 7,450 until June’s ERT switch-off, when phone lines were cut and the “guerilla” program started). They keep doing a full program during the day, but being unemployed, it seems that they cannot carry on overnight.

The official interim public radio (one single service for entire Greece) so far does not care for [the take] over [of] the shortwave and mediumwave resources in Athens. Probably they do not have the staff to operate them, as only the necessary personnel was hired to keep the single radio service running on FM.”

Many thanks to TheGreekRadio.com for this informative explanation.

Thus it looks like VOG’s shortwave service might be easily cut–and without warning. We already know that the Greek government is considering dismantling the Avlis transmitting site.

FCC championing change that could “Bolster AM Radio”

FCC Commissioner Ajit Pai (R)

FCC Commissioner Ajit Pai

It appears that FCC Commissioner, Ajit Pai, is pushing a plan to revitalize declining AM radio station and listener numbers in the US. Read some of the details below or the full article on the New York Times website.

Many thanks to David Goren for the tip!

(Source: NY Times)

The [The Federal Communications Commission] announced late Thursday that it would begin seeking public comment on numerous changes[.]

[…]Because of interference caused by consumer electronics, smartphones and the like, AM radio often seems to deliver mostly static. The AM audience has fallen to 15 percent of all radio listeners, down from 50 percent as recently as 1978. While the FM audience has fallen as well, it draws more than five times the audience of AM.

[Steps include] eliminating a regulation requiring stations to prove that any new equipment decreases interference with other stations — a requirement that is expensive, cumbersome and difficult to meet.

The F.C.C. has also proposed eliminating or loosening rules that govern nighttime transmissions by AM stations. Those regulations currently require many AM stations to reduce their power or cease operating at night to avoid interference with other stations.

[…]The current regulations make it difficult for AM stations to locate towers where they will not interfere with nearby stations at night. They also put conflicting requirements on stations, mandating that they still cover most of their broadcast territory even while operating at reduced power.

The proposed new rules, the commission said, aim at keeping more stations on the air at night.

[T]he F.C.C. said it was ready to make available to current FM stations what are known as FM translators — empty spots on the FM dial where AM stations can broadcast. Those are particularly valuable in urban areas, where tall buildings with steel frames or aluminum siding can block AM signals, degrading reception.

40th Anniversary Montage of ILR Radio Stations

IRL-StationLogosHat tip to Mike Barraclough for sharing a link to this audio/video montage on the BBC website celebrating the 40th anniversary of Independent Local Radio (ILR) with air check clips from stations across the country.

Even if you have never lived in the UK, there’s some serious radio nostalgia in this montage.

Many of these ILR stations still broadcast today, and you can listen to the majority of them via TuneIn radio.

Frank’s maritime radio suggestions

In response to my previous post, The Best Shortwave Receiver for Your Boat or Yacht, Frank (VK3JFH/VP8DNM) writes:

“I have all three of the portables mentioned, the Sony SW7600GR, the Sangean 909X, and the Tecsun PL-660. The latter is currently my portable of choice. Having just read this post re radios afloat I took the time to suck down a fax from Charleville, Queensland.

Results shown..

This was with the Tecsun 660 attached directly to a (near) horizontal longwire at my home QTH, inserted directly into a Macbook Pro running CocoaModem 2.0 via the headphone socket on the Tecsun.
I have had similar results with the Sony and the Sangean

To all intents the result is as good as with my other radios ( K5000 etc.).

(Click to enlarge)

Screenshot of the weather fax image (Click to enlarge)

However if I was starting from scratch afloat I would get an Icom IC-718. Only $689.95 from Universal Radio. You may choose to simply use it as a receiver or as a Ham TX/RX. However it can also be ‘opened up’ with a simple diode snip to transmit on all the marine bands. Not strictly legal [nor is the IC-718 designed for those bands] but there are a lot of ‘opened’ 718s out there and in an emergency you can transmit a mayday on anything…. even a couple of jam tins and string although you may need a fair old length of string….

If you wish to transmit on your IC-718 you will need a tuner. I have an LDG IT-100 on mine.

Hooking up a consumer receiver to a marine antenna….? Simply make up a pigtail with a 3.5mm jack at one end and a BNC or SO -259 at the other.

Non-marine radios afloat…. ? I had an IC-735 aboard from Cyprus (1992) until Patagonia (2007). Since 2007 I have had an IC-706Mk2G afloat…. no problem with either one.”

Many thanks for your input, Frank!

The best shortwave receiver for your boat or yacht

[Updated: October, 23 2017]

SWLing Post reader, Bob, recently emailed the following question:

Yacht“My wife and I live on a boat and plan to go to the Bahamas this season. We cannot afford to install a SSB radio – costs $7K to $8K. But we need to be able to hear the weather reports and forecasts

So we are thinking of just getting a SW radio receiver.

A friend has purchased a Grundig satellite 750 but it does not seem to have the range, and he has not been successful connecting an antenna.

I think I need a SW radio I can connect to an antenna. I am thinking of a CommRadio CR-1 ?

What do you think?”

Thanks for your question, Bob.  I’m going to give you a few suggestions, then open this one up to your fellow SWLing Post readers, as I suspect there may be some with experience setting up and using an HF receiver on the water.

ImportantAs Bryan commented, just after I posted this review, readers should note that none of the receivers/transceivers I offer here are designed for maritime use, thus they lack features like GMDSS, DSC and DGPS and have no extra protection from the corrosion of salt water on their circuit boards.

Receivers

The CommRadio CR-1

The CommRadio CR-1

For my part, as an inlander, I think you’re on the right track with the CommRadio CR-1 or CR-1a.  Not only will it cover the entire HF spectrum (for HF weather fax, RTTY and many ship-to-shore communications), but it also covers VHF (64 – 260 MHz) and UHF (437 – 512 MHz) frequencies. The CR-1 is also a very stable receiver and covers all of the modes you’ll need (upper side-band, lower side-band, AM and FM).

If you’re space conscious, fortunately the CR-1 has a very small footprint; you could mount it nearly anywhere. The CR-1 also has a built-in battery pack and can run/charge on an array of DC voltages (6-18 VDC).

You may also wish to consider the Alinco DX-R8T (see our review) or the Icom R-75. The Alinco has a detachable face plate, thus may also be easily accommodated. The Icom R-75 is a great receiver for your application, as well, but is larger than the CR-1 and does not have a detachable face plate option.

Again, I think you’re on the right track with the CommRadio CR-1.

Another option to consider…general coverage ham transceiver

The Kenwood TS-480SAT is full-featured, small, and has a detachable face plate.

The Kenwood TS-480SAT is full-featured, small, and has a detachable face plate.

Here my advice is going to sound a bit like that which I gave reader Phil recently: I would strongly urge you to get your amateur radio license.

It’s a simple process–even elementary kids do it–and the license no longer requires a knowledge of Morse code (CW), (although I am a devotee of code and would suggest pursuing a knowledge of this at a future date).

Moreover, the testing material will make for an excellent primer on radio communications, so if something goes wrong in the middle of the ocean, you’ll be better prepared to diagnose and fix it.

The Yaesu FT-857D

Additionally, in case of an emergency, a ham radio transceiver would provide yet another means of calling SOS to a community that is well-versed in handling emergency communications.

Check out this previous post for suggestions on getting your amateur radio license.

Ham radio transceivers also offer excellent stability and the modes you’ll need to decode any voice or digital mode.

Keeping in mind that you’ll need a transceiver 1) in the same price range as the CR-1, 2) that is compact or has a detachable face plate, 3) has a general coverage receiver, and 4) is rated for 100 watts of output power, I would suggest the following:

The Linco DX-SR8T

The Alinco DX-SR8T

  • The Alinco DX-SR8T. While not a small radio, this rig has a detachable face plate (with optional extension cord), a sensitive receiver and is a great value at $520 new. I favorably reviewed the receiver-only version of this radio two years ago. I’ve heard that the receiver in the DX-R8T is identical to the one in the DX-SR8T. I would purchase this from Universal Radio or Ham Radio Outlet.
  • The Elecraft KX2

    The Elecraft KX3 or Elecraft KX2 are two of my favorite general coverage transceivers–I own both. They can both be powered from a modest 12 VDC source and/or internal batteries. Both are limited to QRP (12 or 15W) transmit power, but an external portable 100W amp can be added. Both are exceptional radios in terms of performance.

  • The Kenwood TS-480SAT. Also worth considering, this transceiver has an excellent receiver with better filters and a smaller footprint than the Alinco DX-SR8T. Though it costs nearly twice as much as the Alinco, it’s on sale until 11/30/13 for $974 from Universal Radio.
  • The Yaesu FT-857D.  This is probably the most compact among the transceiver options listed above. The FT-857D has been on the market for many years and has proven itself a capable mobile transceiver. The detachable face plate could easily be mounted anywhere you wish. The Yaesu FT-857D can be purchased at Universal radio or Ham Radio Outlet.
  • The Icom IC-7000 is an excellent choice for maritime operation. It's possible to find a used one at a good value.

    The Icom IC-7000 is an excellent choice for maritime operation. It’s possible to find a used one at a good value.

    Also consider buying a good-quality used general coverage transceiver from a reputable retailer like Universal Radio, Ham Radio Outlet, The Ham Station or Amateur Electronic Supply. Search for the three models listed above, but I would also consider the Icom IC-706MKII and the Icom IC-7000.

Of course, you will need a good HF antenna for any of these options to work, even the CommRadio CR-1; a radio, after all, is only as good as its antenna.  The type of antenna you can use will be limited by your ability to mount it on on your boat: some are limited-space wire antennas, others are whip antennas.  Make sure the antenna will resonate on the frequencies important for your maritime travels.

Fortunately, most of the retailers listed above have experience in this capacity.

Portables

If I were on a boat, I would also carry a portable shortwave radio as a backup. Some to consider are the Tecsun PL-660, Tecsun PL-880Sony ICF-SW7600GR or the Sangean 909X. All of these have SSB mode and good sensitivity, selectivity and stability, although the Sangean ATS-909X requires an external antenna for optimal sensitivity.

There are also a few compact travel radios worth considering as well, although sensitivity generally isn’t as good as the larger, full-featured portables mentioned above. I would consider the CountyComm GP-SSB, Digitech AR-1780, or the C. Crane CC Skywave SSB as a nice spare radio to tuck away on board.

Hope this helps, Bob!  Happy sailing!

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)

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

The Tecsun PL-380 receives circles around the DE32 and DE321 on shortwave and medium wave (Click to enlarge)

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.
