VOA Launches Rohingya Language Program

Today the Voice of America’s Bangla language service started a five-day-a-week radio show in Rohingya, the language spoken by Muslim refugees that have fled Myanmar. More than 800,000 people have taken refuge at the Kutupalong camp, one of the world’s largest refugee camps at the Myanmar-Bangladesh border.

Titled Lifeline, the 30-minute radio show, is available through short and medium wave signals. The program focuses on the lives and needs of the refugees, providing them with valuable information on security, family reunification, food rations, available shelter, education and health including vaccinations and water purification. In addition, a daily segment of the program offers the refugees the opportunity to share their stories, extend greetings to their families and learn about the hazards of joining extremists groups. One overarching objective of the broadcast is to counter Muslim extremists’ narratives and recruitment efforts in the camps and inform the Rohingya about the U.S. and the international community’s involvement in the crisis.

“After visiting Cox’s Bazaar and the Kutupalong refugee camp last year, it became obvious to me that we needed to address the informational needs of these people caught in the fastest growing refugee crisis in the world today,” said VOA Director Amanda Bennett. “Providing them with a reliable and authoritative source of news, as well as practical information that will improve their lives, is what the Voice of America does well in various hotspots around the world.”

Prior to launching the Rohingya language program, a VOA Learning English team travelled to the Rohingya refugee camps in Cox’s Bazar, Bangladesh, in March of this year at the invitation of the United Nations High Commissioner for Refugees. The VOA instructors offered six days of intensive training on teaching techniques and methods for 100 selected English teachers. The teachers, in turn, will use the acquired knowledge to train another 5,000 of their colleagues in the camps.

Imre’s HanRongDa HRD-737 modification increases sensitivity

Many thanks to SWLing Post contributor, Imre Olajos, who writes:

Hi, HRD 737 lovers! I have a good news!

I  (became brave enough to) modify my HRD-737.

I tried reverse-engineering- but I gave up. No numbers on IC-s. I found specifications for the analog switches (one for each band ) and found information about the transistors around those analog switch IC-s. Nice, 1 GHz fT transistors, all surface mount, so I gave up that line.

I found an NPN SM transistor in a damaged TV remote. It is only a 300 MHz transistor but
I had no better than that, so I started to build a little antenna amplifier circuit, wide band and simple.

I lost a few SM capacitors during the soldering but I have plenty of those. So the 1/4 square inch circuit board was finished last week. I tested it with an external 3 volt battery and I found it good working. Today ( 07-27-2019 ) I opened up the HRD-737 and wired it into the radio.
The results are much better than I expected. The HDR-737 became a good shortwave radio!

When I touch the built in antenna by my finger, radio is sensing the touch and station comes in. This effect was not there before. Radio became more sensitive on CB band than my Realistic DX392.

I have a YouTube channel [in the following video/slideshow] and I will show you the little ugly but great working circuit in the radio:

Later on next week I will try to record some video of the shortwave reception and post up it on the same YouTube channel.

I am a shortwave lover since 50+ years and I will be very happy to share the good news with others. Now I can listen my Greek music on this little radio, on 9420 kHz. Yes, the radio became [more sensitive than I had hoped].

You can see my other shortwave radios on my YouTube channel too, Have fun and never give up the hope!

Many thanks, Imre, for sharing and documenting this modification. One of the lessons here, too, is that if you have an inexpensive radio like the HanRongDa HRD-737 and you feel tempted to try a modification, there’s little to lose. It’s not like modifying a $1000 transceiver–just dig into the little radio and give it a go. If you harm the radio, you’ve only invested $37 or so in the project. That’s a much better solution than letting it sit on a shelf collecting dust because it’s not sensitive enough! Well played, Imre!

A photo tour of the 2019 WCARS hamfest

Yesterday, I attended the WCARS hamfest in Waynesville, North Carolina, with my friend Sébastien (VA2SLW) who is currently on vacation in the area.

The WCARS hamfest is a smaller regional hamfest, but it attracts a lot of folks from the mountain regions of north Georgia, Tennessee, South Carolina, North Carolina, and beyond.

The WCARS hamfest flea market always has quite a variety of radios, including a number of great vintage models. I’ve been very lucky in the past finding excellent deals, too. This year, I (reluctantly) passed up a few deals knowing I’m also attending the Huntsville Hamfest in August and the Shelby Hamfest in September.

Below, you’ll find a selection of photos from the hamfest. Note that you can click on the image to enlarge it and I attempted to include price tags when possible:

Review of the C.Crane CC Buds Solo In-Ear Single Earbud (and a chance to win one!)

A few weeks ago, C. Crane sent me one of their newest radio accessories: the CC Buds Solo Single Earbud.

Here’s the description from the C.Crane product page:

Single Earbud Optimized For Voice

The CC Buds™ Solo single earpiece provides a unique advantage over traditional earbuds because it allows you to interact better with others while listening to radio, podcasts or audiobooks (your boss will love you). The integrated stereo to mono plug works with smartphones, radios, tablets, and most other audio devices.

The Solo can give you a safety advantage when running, biking, or walking because you are more likely to hear if danger approaches. The cable is Kevlar™ reinforced for maximum durability. It is perfect for scanner radio listening. Can work well for law enforcement when greater awareness is needed.

Audio is tuned for superior voice clarity. Included are three silicone and three compressible foam covers––sized small, medium, and large. The small covers usually fits a small ear comfortably. Standard 3.5 mm headphone jack. Cord Length 48″.

At first blush, the idea of a single earpiece smacks of vintage solid-state radios. I’ve a number of classic portables that were designed around a hard-plastic single earpiece–anyone else remember those?

In fact, my Sony ICF-5500W (above) even has a little compartment to house its custom earpiece.

The Sony ICF-550W’s unforgiving 1970s era earpiece.

In my youth, I carried a hard plastic single earpiece with me everywhere, especially at school, because it made listening to the radio and still having some situational awareness possible. [Unfortunately, I was known to listen to the radio during classes…what a renegade I was back then!]

If you, too, used those hard plastic earpieces, I doubt you’d have ever described them as “comfortable.” I never found them even remotely so. Those earpieces were functional, but the audio they produced was tinny and it was always difficult to keep them in my ear.

Think of the CC Buds Solo as the earpiece we all wish we could have had back then!

The Solo includes numerous earpiece options, a carry bag and owner’s manual.

Here are some of the CC Buds Solo pros:

  • The audio quality is superb for spoken word
  • The earpiece is very comfortable (see notes below)
  • The audio plug allows for mono listening on stereo devices (obviously a must in 2019)
  • Features a super-strong Kevlar-reinforced cord
  • Includes a clothing clip that acts as strain relief
  • Ships with a small, soft carry bag

So does the Solo deliver what it promises? Yes, it does.

What I really love is the number of soft silicon and foam earpieces that ship with the Solo: a total of seven options, when including the default earpiece.

If you’ve ever used in-ear earbuds, you’ll understand the importance of swapping out the soft earpieces to a size that best suits your ears––that is, to a size that makes for a comfortable seal.

The Solo might also be useful if your hearing is a bit better in one ear than the other.

Unlike single earpieces of old, it’s actually a pleasure to use the CC Buds Solo earpiece.

Before using the Solo, I would often wear only the right earpiece of my stereo earbuds when I needed to be able to hear the environment around me. This obviously isn’t ideal because the left earpiece would dangle, catch on my shirt or otherwise get in the way, and often lead to jerking out the right earpiece. Not to mention, it led to an awkward muffling (or altogether missing) of some of the sound in that other dangling earbud when stereo sound is split or processed differently for each ear. Clearly, not the best way to listen.

Note the adjustable clothing clip.

Now, when I’m driving, working, or walking, I can use the Solo clipped it to my shirt; it’s a more simple and annoyance-proof solution that allows for greater mobility and permits me to hear all of the intended sound.

I’ve only used the Solo for spoken word; primarily AM/SW broadcast band listening and for listening to podcasts.

These days, while I’ve been at work on a home renovation, podcasts have become an essential part of my day by helping me pass the time while painting, sanding, cleaning, mowing, doing yard work, or carrying out other tedious tasks. A good podcast definitely keeps it fun. The Solo makes podcast listening easy.

And of course, the Solo is also a great solution for listening to audio books, too.

I’ll admit, when I first saw the product announcement for the CC Buds Solo, I was curious if there’d still be a market for a mono earpiece. I suppose I proved it, myself, as I have found it quite useful when I don’t need the total isolation or stereo sound from two in-ear earbuds.

Well played, C.Crane!
