Radio Go Bag: JC recommends this affordable shoulder pack

Bag-TacticalSpeaking of backpacks and protective cases for radios, SWLing Post reader, JC, recommends an inexpensive tactical shoulder pack available via eBay.

JC writes:

I tend to want a little more protection and space so I use a tactical military type shoulder bag for my portable radio kit. It hangs nicely off the back of the passenger’s seat in my car and allows me to keep my PL-660, spare batteries, portable wire antenna, earphones, frequency lists, and other gear all together in a handy pack.

The price is about $13.60 w/ free shipping. It’s a great bag for my portable kit, and it’s built pretty sturdy. Any extra protection is better than none for a radio used out in the field.

Thanks for the recommendation! That is incredibly affordable and a great looking bag.

I’m very partial to Spec Ops Brand packs, but they’re quite pricey in comparison.


beomaster900-closeWhile quite out of my price range, this is a beautiful piece of radio art nevertheless. (I recommend viewing the close-ups on the listing to really see it.) The receiver/amplifier has Broadcast, Long Wave, Short Wave plus FM, and the ability to reproduce beautiful stereo for its time, according to user reports.These were produced during the mid-sixties until 1970. I miss the artwork involved in many older radios as compared to today’s utilitarian radios. We may have better components and features, but we do not have the beauty or style in many cases.

I’ll be watching with interest to see how this auction ends!

Protecting your investment: Troy’s radio case recommendations

IMG_1293Many thanks to SWLing Post contributor, Troy Riedel (the Amateur Astronomer), who writes:

I’m rather – uh – call it OCD re: equipment cases (and bags/packs).

All of my […]astronomy equipment is well secured & cataloged in several dozen cases.

I [also] wanted to protect my shortwave radios. I like the neoprene cases that Tecsun ships with their radios as they have a bit of shock absorbing capacity. I went online at Amazon & eBay and I bought “neoprene” cases of various sizes made for GPS units, external hard drives, and tablets.


Upon receiving them I’ve found the 3.5-4″ GPS cases are perfect for the Grundig G6 and similar sized radios.

IMG_1295 IMG_1290

Belkin “Grip” tablet cases are perfect for the Grundig G3/G5. And the larger “iLuv Gaudi” case is prefect for the YB400 & Sony ICF-SW7600GR. The iLuv even has memory foam. I feel I could drop any radio in this iLuv case from a reasonable height and the contents would be perfectly fine.

Including shipping, I spent $6 for the most expensive case and as little as $3.95 for the least expensive.


The iLuv memory foam case, in silver, was only $4.99 and free shipping via Amazon Prime. Some of the cases have exterior zipped pockets perfect for ear buds and a USB cable. The neoprene has the capacity to stretch a bit, so all of them are a snug fit. Though there is an extra 1/2″ on the iLuv case, the memory foam quality ensures a nice, tight fit.

I’ve attached a few pictures to illustrate my finds.

BTW, I also noticed today that The Worldwide Listening Guide is priced at $21.62 on Amazon. That’s down from $24.95 and a good deal with Prime.

Thanks so much for sharing your research, Troy. I have just added the iLuv case to my Amazon cart. Like you, I have a Sony ICF-SW7600GR and it gets taken to the field a lot. The 7600GR comes with a nice custom case/cover, but it offers little in the way of protection–$4.99 is a reasonable cost to protect one of my favorite portables.

Like you, Troy, I have a serious addiction to quality bags and cases.  I hope you know that you’re only enabling me! Ha!

Readers: Please share your radio case/bag recommendations as well!

Maritime emergency ham radio recording


An SWLing Post reader recently sent me the following YouTube video–a recording Hanz (W1JSB) made on the 20 meter ham band several years ago. Here’s his description from YouTube:

Several years ago I was tuning around the 20 meter amateur radio band and heard this lively, engaging, and impressive exchange on the maritime mobile frequency, 14.300 MHz.

Vessel ‘Elusive’ at sea in the North Pacific was being followed by another ship. The occupants felt threatened that it might be a pirate, so they called for help on the HAM

Volunteer radio operators around the country worked together to communicate and relay messages with the Coast Guard in California. They also came up with some brilliant ideas to stay safe and get direct help as soon as possible.

The following is a recording from my location in New Hampshire.

Many of us who’ve been long-time SWLs and ham radio operators have heard interesting broadcasts and exchanges on the HF bands. Please feel free to comment with your notable listening moments!

Bill recommends the Signal Identification Wiki


Many thanks to SWLing Post reader, Bill, who shares a link to this Signal Identification Guide:

Curious if any readers have been using this guide–seems like a convenient resource to ID those numerous signals on the bands. Entries show what each signal looks like on a spectrum waterfall display and provides audio clips.

Thanks for the tip, Bill!

Why Shortwave Radio is Still a Superior Educational Technology

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.
