After switching off a number of high power transmitters in 2015, at the end of December the Dutch government has launched a public consultation on ‘opening up’ the medium waveband for radio and non-radio applications with ‘low power’ and with limited government regulation.

When referring to ‘low power’ this means both a power in the range of 1 – 5 watts (site coverage) and 50 – 100 watts (municipal coverage). The idea is that the same frequencies will be re-used across the country. They will be handed out on the basis of a first-come, first served basis. Deadline for comments is 14 February 2016.

Reader and contributor Dr. Ed Harris recently authored an excellent article in which he describes why shortwave radio remains a practical and accessible educational technology in today’s world.

And he should know.  Ed––a long-time DXer and world traveler, currently studying to be a ham radio operator––is also a professor of educational leadership at Oklahoma State University College of Education, where he teaches courses in leadership, ethics, and research. Additionally, he oversees the Brock International Prize in Education, which discovers and awards the best ideas in education and showcases them to the world.

Ed is also an Ears To Our World advisory board member––not to mention, a good friend: we’ve travelled together on behalf of Ears To Our World to offer support with educational technologies in parts of the world where they’re needed.

Ed has kindly allowed me to post his full article here on the SWLing Post, as I believe many of you will appreciate this.

Using  “Whole Earth” Criteria to Explain Why Shortwave Radio is Still a Superior Educational Technology

Ed Harris, Oklahoma State University – College of Education

            As a professor of education, I see concerted efforts across the planet to increase educational opportunities for all global citizens. Governments and institutions are acknowledging that education is vital to social and economic sustainability for everyone, everywhere. For some global citizens, the convergence of the Internet with modern instructional technologies has provided advanced and rewarding educational opportunities.  However, numerous geographical regions are still plagued by educational inequities that result in social and economic disparities.

While there are no quick fixes for these inequities and disparities, the issues can be boiled-down to two interrelated factors:  (1) isolation (i.e., insulation from available and accessible services) and (2) poverty (i.e., insufficient means to procure services). Isolation is a huge problem domestically and abroad. In all parts of the world, rural is rural.  In those areas where people are geographically or politically isolated from available services, the Internet and innovative technologies actually perpetuate educational inequities and widen the digital divide between the have and have-nots.  Moreover, in many areas, the lack of money for basic electricity and Internet subscriptions compound the problem, making educational inclusion virtually impossible.

A few years ago, a colleague and I published an article regarding the above dilemmas in light of the accessibility and sustainability of modern educational technologies.[1] We explained that although we live in the 21st Century, we could benefit significantly from the criteria that “Whole Earth Catalog” used to select sustainable, user-friendly tools for their publications.

For you non-Baby Boomers, the “Whole Earth Catalog” was a collection of creative articles and durable, practical tools published from 1968 to 1972 and sporadically thereafter.[2] Whole Earth editors did not just curate tools; they curated ideas and promoted a philosophy by which to use those tools. Whole Earth technologies were timeless and provided opportunities for personal growth and social development. Before any product was included in the Catalog, it must have met a rigid set of standards:

  1. High quality at a reasonable cost,
  2. Easily accessible,
  3. Useful and relevant to independent or self education, and
  4. Capable of launching a cascade of new opportunities.

Rather than applying the above criteria specifically to radio, we applied them to a wide array of instructional technologies. However, when shortwave radio is held up to the scrutiny of Whole Earth’s standards, readers can see below that radio clearly ascends to the top of the “ed-tech” pyramid.

Standard 1: A Good Tool Offers High Quality at a Reasonable Cost

EtonRadioHigh quality and affordability are obvious factors in any discussion on sustainable technologies. Educators must consider the cost of ownership and return on investment as they seek to adopt new educational technologies. While computers and mobile devices are quite popular in today’s educational settings, their cost prohibits them being used by many across the globe. On the other hand, shortwave radio is relatively inexpensive. Low-cost shortwave receivers can be purchased in almost every part of the world.             Moreover, simple, inexpensive shortwave regenerative receivers can be easily built with a few parts. Even in the most disadvantaged parts of the world, one can find shortwave receivers, and many radios now include hand-cranked devices that provide power without batteries. To add to radio’s cost appeal, listening is absolutely free and does not require special apps or subscription fees.

Standard 2: A Good Tool is Easily Accessible

In the “Whole Earth” days, accessibility was expressed in terms of how easily the technology could be mailed or shipped. For instance, while large harvesting combines were not seen in the publications, sickles, pocketknives and books were prominent. An inaccessible tool is useless, while an accessible tool is invaluable.

Academic fields such as Educational Technology differentiate between (1) availability, which concerns how readily obtainable a technology is, and (2) accessibility, which concerns the skills one needs to successfully employ the technology in the manner intended. An example might be digital library services. Most universities make available a wealth of research materials online for anyone who has university credentials to log in to their system. However, while these materials are available, they are not necessarily accessible to users who are unable to navigate the library website, remember his or her login credentials, or have the search skills to interact efficiently with digital databases. Thus, when adopting new educational technologies, both availability and accessibility must be considered and planned for.

Earth-ClipArtRegarding the accessibility of shortwave transmissions, radio may be the most available and readily accessible technology in the world. Shortwave radio remains the only medium capable of direct communication from one country to listeners in another country without intermediaries such as satellites, cable companies, or Internet providers. Shortwave signals can be accessed anywhere on the planet, and radio is a safe way of providing information to areas of conflict or during an emergency.

Unlike most other radio communications frequencies (such as those used by FM radio, WiFi networks and Mobile Phones) which are limited to local or line-of-sight propagation, shortwave radio signals bounce off the ionosphere and blanket earth with broadcasts and information.  Every corner of the globe can receive shortwave radio broadcasts with even a simple $20 portable radio. When radio is seen as an available, accessible, and affordable educational tool, potential educational opportunities sources dramatically widen and serve to bridge the digital divide.

Standard 3: A Good Tool is Useful for Self-education

ETOW-Uganda-RadioFor educators, self-directed learning (SDL) is a top goal in the educational process. In SDL, the individual learner takes the initiative and the responsibility for what occurs and has the opportunity to choose from a range of available and appropriate resources. Thus, since opportunity and choice can empower a person to grow in his or her capacity to be self-directing, these factors should be nurtured and promoted in educational processes.

The Internet is example of a technology that nurtures self-direction and promotes both informal and formal learning opportunities. However, even the Internet does not surpass radios usefulness in self-education. Research indicates that radio is more than just music, news and entertainment. Rather, radio listening can meet educational needs such as individualized learning, belongingness, self-esteem, independent learning, and even self-actualization in a variety of different ways. Listeners can engage simply by selecting the format type that meets their requirements at any specified period of time.[3]

Moreover, radio listening is edifying because listeners hear current events and ideas from different perspectives across the world. The choices of the learner in radio listening are paramount because he or she can choose the station, choose what they want to get from the experience, and choose with whom they would like to share that experience.

Standard 4: A Good Tool Launches a Cascade of New Opportunities

Opportunity-ClipArtWhole Earth editor Kevin Kelly often reminded readers that all technologies create their own set of problems; however, superior technologies result in new opportunities and ways to solve problems.[4]  Whole Earth was at the forefront of reminding readers of the cycle of  (1) new tool, (2) new challenges, and then back to (3) new tools. In educational terms, when a learner completes a learning cycle, he or she is not only gaining personal and professional knowledge and skills, but impacting future learning as well.[5] The cyclical cascade of opportunities from shortwave radio is impressive. For example:

  • The opportunity of creative imagination and proactive listening. Radio listening feeds imagination and brings an auditory dimension to our lives. It allows for networks of mental associations, and facilitates the listener to vicariously “visit” new places and new cultures. These opportunities serve to facilitate the formation of identity, purpose, and listening skills vital to good communication.[6]
  • The opportunity of connections. Radio listening broadens connections and increases community. Radio listening helps both in making connections of desperate pieces of information and in being connected with each other and to the world. Understanding the interconnection of knowledge is vital in the learning process. Radio listeners hear different perspectives from around the world and are automatically put in the arena of connection making and discernment. Also, radio listening can be a community endeavor in itself.
  • The opportunity of inherent learning about radio. The radio is an educational device, and subjects that can be integrated in radio listening include geography, sociology, politics, mathematics, and a host of others. However, the radio device itself is instructional. Understanding electronics, circuit construction, safety, modes and systems, propagation of radio frequency signals, serving equipment, and progressing host of others.

Summary and Challenge

A good question would be, “Well, did Whole Earth Catalog include shortwave radios in their publications?” The answer is yes. In almost all their publications, radio – i.e., shortwave, amateur, electronics, books/guides, education, and/or communication – was referenced in some way. For example, on page 259 of the special 1994 publication, THE MILLENNIUM WHOLE EARTH CATALOG: Access to Tools and Ideas for the Twenty-first Century, the Sony ICF-SWIOO Receiver was showcased. In that edition, the authors commented, “No alternative yet proposed (satellite radio, personal wireless computer gizmo) offers the same combination of a cheap, portable receiver and program content that crosses borders unfiltered by any government or corporate gatekeeper.”

While technology is constantly evolving, the wisdom of Whole Earth prevails — the wisdom inherent in using technologies that promote a sustainable lifestyle. In education today, we are continually seeking innovative, timeless, and empowering technologies to promote sustained learning for all.  Just as the publishers of Whole Earth Catalog understood, educational technologies are best adopted from grassroots efforts, and those technologies adopted, must empower users to take learning, teaching and research to deeper, more meaningful levels.

The radio has been with us for a long time, is still be a superior instructional technology, and can have an important place in education. However, those of us who have this vision must collaborate to regenerate enthusiasm for this valuable medium as well as devise cost-efficient, user-friendly, and sustainable solutions. Some suggested goals could include the following:

  • Develop school broadcasts that include curriculum-based content and professional development content for educators;
  • Develop and utilize existing language learning programs aimed to teach a variety of languages;
  • Utilize interactive radio technologies that allow for asynchronous feedback and communication;
  • Develop cooperative relationships with regional governments and/or educational institutions to store and broadcast programs for broadcast to the peoples in their respective areas.

Innovative ideas, interconnections through sharing those ideas, and purposeful inclusion of technologies in today’s educational landscape echo the rationale behind Whole Earth Catalog. So in striving for sustainable tools for 21st Century education, as Whole Earth readers were reminded in every issue of the Catalog, we must seek technologies and skills that empower individuals to take ownership of their education, shape their environments, and especially, share the adventure with whoever is interested. When addressing these challenges, shortwave radio is still a viable, superior educational solution.

A Review of Multipsk Software for Digital Modes and More

http://ak3q.com/wp-content/uploads/2016/01/MPSK2.jpg

Over the last year or so I have been using a really full-featured digital mode software called Multipsk, and it has become my go-to software for most digital modes. Back in September 2015 I wrote an extensive review of the software for The Spectrum Monitor (TSM) which Owner/Editor Ken Reitz has graciously allowed me to post on my blog at All Things Radio. Thomas has written numerous articles for TSM, and will attest to its emphasis on so many aspects of the radio hobby. If you are not a subscriber already you really do not know what you are missing!

The program boasts over 75 modes, not counting some of the many sub-modes or variations, and new modes are being added all the time. There is a free version and a registered version, with the paid mode costing around $45 (U.S.) The free mode will handle a lot of really great modes, but I confess, it was the additional “professional” modes which really made purchasing the registered version a must for me. Whichever way you go, you will not be disappointed. As I have noted on my blog and in the article itself, I consider the registration fee some of the best money I have ever spent for computer software.

As an added bonus, the free or registered version can be run on as many computers as you have in your home, and multiple instances of the program can be run on the same computer provided they are in separate directories. This is a great feature, and it means there is basically nothing going into the Windows registry file–the program runs right from the directory. My only problem is not having enough antennas to have as many instances of the program running as I would like!

I hope you will take time to read my review and then get the program–I think you will be suitably impressed as I was! (I have it running on XP machines through Win10, so compatibility should not be an issue.)

The Worldwide Listening Guide: the content DXer’s handbook

WWLG-7th-EditionI’m very pleased to have just received the 7th edition of John Figliozzi’s Worldwide Listening Guide (WWLG), the latest, most updated version of the excellent guide I’ve often reviewed.

As I’ve said, you may want a copy of the WWLG in your shack, especially alongside your computer or Wi-Fi radio.

SWLing Post readers know that I’m a huge fan of the Word Radio TV Handbook (WRTH); it’s my go-to guide for radio frequencies and schedules. Well, Figliozzi’s Worldwide Listening Guide is my go-to for programming and content, not only helpful on the shortwaves, but also handy when tracking online content.

WWLG: The Content DXers Guide

Like many SWLs, I’m something of a “Content DXer:” I love chasing obscure programming––news, documentaries, music, and variety shows, anything the broadcasting world has to offer.  For this, I often turn to Wi-Fi radio.  Wi-Fi radio offers the discerning listener the ability to track down fascinating regional content from every corner of the globe––content never actually intended for an international audience.

But the fact is, there’s so much content out there, it’s hard to know where to start. This is where the WWLG comes in: Figliozzi exhaustively curates more than 4,000 programs (!), indexing their airing times, stations, days of broadcast, program types, frequencies, and web addresses. Additionally, he sorts the programs by genre:  arts, culture, history, music, sports, and more. And Figliozzi also includes a well-thought-out directory of at least forty genres.   In short, this directory has helped me not just locate, but identify, programming I would never have known about otherwise.

Frankly, I’m not sure how Figliozzi manages to curate such a vast assortment of programming.  But I’m happy that he does, and especially, that he offers it for the SWL’s benefit––!

Thus the WWLG  has become a permanent reference book in my shack, alongside my trusty WRTH. There’s a surprising amount of information packed into this slim, spiral-bound book…enough to keep even a seasoned DXer contented for years.

The 7th edition of Worldwide Listening Guide can be purchased here:

With a retail price under $25, I feel like the WWLG is an excellent bargain.

Alexander reviews the Avion AV-DR-1410 DRM receiver

81-58a+inIL._SL1500_

Many thanks to SWLing Post contributor, Alexander (DL4NO), for the following review of the new Avion DRM receiver:

A review of the Avion DRM receiver

by Alexander von Obert (DL4NO)

The Avion AV-DR-1401 DRM receiver has appeared on the SWLing Post before in a previous review.

Amazon India does not sell the Avion outside of India. As it happens, I found someone who was willing to buy it for me and bring it with him from India to Germany.

The first impressions were quite disappointing. This feels more like a prototype, not a polished product:

  • The power supply produces lots of interference and runs quite hot. Unless I find another power supply, I can either charge the battery or listen to the radio.
  • The handle rattles. Such things often are symptoms for the whole product.
  • The firmware fails in many ways: update errors of the display, very confusing user interface.
  • No acceptable field strength indicator, especially in DRM until a signal is decoded. If you have a selective antenna you need to switch to AM to tune it. And then you tune it by ear or by numbers. No bar of any kind.
Avion AV-DR-1410 DRM

Radio Romania

Radio Romania produced very good signals this evening in southern Germany on 41m. But with the built-in antenna, DRM reception was impossible even in my shack directly under the roof. A Degen 31MS selective active antenna indoors enabled sketchy reception of Radio Romania and All India Radio on 41m. Reasonable reception was only possible with my external antenna.

All India Radio

All India Radio

Just imagine why I took the trouble to get the receiver! It is a far cry from what I really wanted: a modern replacement of my trusty Sony ICF7600D from the 1980s. I had to retire it for mechanical reasons after it travelled with me for 20 years.

In India, they might not have the industrial infrastructure they have in China or Japan, but an intensive firmware update is urgently needed. Software is something they are good at in India. Many problems could be solved that way:

  • The volume knob has no stop and must be pressed for a few seconds to turn the radio on or off. A short press could be used to switch it between volume and tuning.
  • A reasonable field strength indicator should be introduced.
  • The remote control does not work reliably.
  • With the “mode” switch I can select AM, FM, or DRM. But I have not found anything that the “band” switch could be doing.
  • The “scan” switch works on FM and puts all transmitters found into the favorites. But neither is that the function I would expect it to do nor does it work on other bands.

From my preliminary tests I fear the unit has massive large-signal problems. For example, I heard distorted signals of Radio Romania on bands where they were not transmitting at all. I use an active antenna but this is the same I use for the DX Patrol or SDRplay RSP, therefore I know that my antenna is not to blame. I also see this as an indicator about the DRM signal of Radio Romania.

I could not help but open the Avion receiver: [the internal antenna worked so poorly, I wanted to investigate].

I must say that the rattling handle was an accurate indicator of production quality.

Inside the Avion

Inside the Avion

See “Inside the Avion” image above (click to enlarge). The back side on the left was originally covered by an aluminum shield. I had to remove it as the wires are quite short–one cannot put the two parts flat on the bench otherwise. You see that they tried to improve the shielding on the right.

AVION internal antenna preamp

Avion internal antenna preamp

See “Avion internal antenna preamp” above (click to enlarge). The circuit board at the lower left corner of the first picture is the preamp for the internal antennas. In the lower left corner is the telescopic antenna connection. The wire here was extremely short–either it broke before and made contact by chance or I broke it when I dismounted the circuit board. At least I did not force it (still a bad manufacturing practice).

If you examine the circuitry, you see very bad practices: C2 directly connects the antenna to the base of Q2. It must be a bipolar transistor considering R3/R4. At least there is DN1 which seems to be protection diodes. On the whole board I can find no inductivities at all. There is absolutely no band limiting.

AVION broken shilding wire

Avion broken shilding wire

See “Avion broken shielding wire” above. The shielding wire had broken from the soldering. That was definitely not my fault. At the yellow isolation, a second wire is connected. That is the wire routed around the backside without any connection. This doesn’t make sense to me.

Avion crushed battery holder

Avion crushed battery holder

See “Avion crushed battery holder” above. The battery holder is fixed together with the aluminum shielding. The worker crushed the lug of the battery holder while mounting the shield. A few other threads were torn, too. A typical case of too much strength.

Avion seems to know about the inherent RFI problems of this receiver, but could not solve them. No wonder I have to use an external antenna.

Perhaps I will replace the antenna preamp with something reasonable.

Otherwise this radio will gather dust here.

Thank you for your report, Alexander–I’m sorry to hear about your experiences with the Avion, especially after the trouble you went to obtaining it.

So far, I’ve heard no truly positive reviews of the Avion AV-DR-1410. Sadly, it sounds like a radio to avoid.

Mike IDs a Hallicrafters Skyrider in Avengers scene

Avengers-Ultron-Hallicrafters-Radios

In response to my post about finding a glowing Hallicrafters radio in a scene from the Avengers: Age of Ultron, SWLing Post reader, Mike (AC4NS) writes:

“I put the pic in Lightroom and pulled it out of the shadows.

It is definitely a Skyrider and not an SX-28.”

Wow–I’m amazed there was enough information in that photo to pull it out of the shadows! You can see the silk screening and the SEND-REC. switch in the lower right corner.

Again, here’s my Hallicrafters SX-24 Skyrider Defiant for comparison:

My Hallicrafters SX-24

I know why they used a Skyrider in the film; the warm glow of the dials and signal meter were simply irresistible! (At least, they are for me!)

Thanks for helping ID this, Mike!
