2013 WRTH now available

WRTH has announced that their 2013 edition is now available online. Every year, I look forward to searching a new WRTH’s pages for the first time. What is the WRTH (World Radio and TV Handbook)? Click here to read my reviews of the 2010, 2011 and 2012  editions of WRTH. In the 2010 edition, I even include an interview with the publisher, Nicholas Hardyman.

One bag + radio = the way to go

Though I only travel with one carry on bag, it doesn’t mean I can’t accommodates my shortwave radio/recording pack.

Having just returned from nearly three full weeks of traveling, I’m more convinced than ever that my just-one carry-on bag approach makes absolute sense. In one bag, I’m able to take everything I need, including casual and business attire, toiletries, first aid and, yes, of course, my portable shortwave radio (never leave home without it!) and my Zoom H1 recorder.

One bag freedom

Years ago, while working for a fiber optics company in Europe, I learned the trick to keeping my cool during frequent air travel was simply to avoid, at all costs, checking in baggage. Over the course of several years, I honed the contents of my travel bag down to the bare essentials, and even for longer trips in developed countries, made the (correct) assumption that any supplies I required could be found at my destination.

My circa 1999 Eagle Creek convertible laptop bag has traveled thousands of miles. It’s just big enough to accommodate everything I need for several days or even weeks travelling.

For twelve years now, I have been using one of three Eagle Creek carry-on convertible bags. Two of these plain black bags look much like the ubiquitous vertical rolling luggage you see every day in major airports, but they hide two secrets: each can be converted into a full-fledged backpack, and each meets the most stringent standards for carry-on luggage. They’re also built to take a beating, which they’re getting, and have a lifetime warranty.

The third Eagle Creek pack is basically a roomy laptop (and radio) bag (see photo on left). It has no wheels, and can be worn with a shoulder strap…or, again, converted into a simple two-strap backpack.

When traveling alone, I can easily get by with only the third and smallest of my Eagle Creek pack: the laptop bag. It has a very roomy, padded compartment for my laptop, a middle compartment where I fit my bundled clothes, first aid, and radio pack (which also holds my Kindle), and a front section with organizers for office supplies and a convenient place to stash my travel docs and passport. It’s also a very simple to make this pack virtually pickpocket-proof.

This laptop bag quickly converts into a backpack–a useful feature when it’s fully loaded and you need both arms free.

Check-in-proof!

The benefit of using this particular Eagle Creek laptop bag (important: the one without wheels) is that–even if I’m being loaded in the last zone of a flight, even if the flight is fully booked, and even if the flight is on a De Havilland Dash 8-100–I always find a place for my bag on board, and never, ever, have to gate-check my bag. It will fit in a small overhead compartment, or at the very least, under the seat in front of me.

Though the compromise is that I travel light, the great benefit is that I never have lost any bags, rarely miss a connecting flight (it typically takes at least five extra minutes to claim even a gate-checked bag), and I zoom in an out of an airport. I have the luxury of sitting back and reading while I watch others panic at a gate, waiting for their appropriate “zone” to load.

From my seat, I watched US Air load wheeled carry-on luggage that they required some unfortunate passengers (who were already on the plane!) to check in.

Over the past decade, air travel has really changed. Most of the domestic flights I took throughout Europe a decade ago used to be only about two-thirds full. Here in the US, it appeared to be roughly the same. Today, however, airlines have cut back their offerings and frequently overbook flights. In fact, on a recent flight returning from Denver International Airport, the airline warned of penalty charges if passengers attempted to carry on more luggage or weight than allowed. The airline was making anyone with a wheeled bag–no matter how small–check it in.

Since I was in the eighth row seat, and I only had my Eagle Creek laptop bag on a shoulder strap, I waited until almost everyone else had boarded before I got in line. I walked straight into the 737, pulled my radio pack out of my laptop bag, stowed the laptop bag in the overhead compartment, and settled into my seat. No sweat. Meanwhile flight attendants were taking extra baggage from travelers in the back of the plane and checking in their luggage on the spot. Though their bags met overhead compartment criteria, there simply wasn’t enough room.

Confession time: So, I am something of a pack addict…!

My wife recently pointed out that, besides radios, I have too many packs. I’m convinced I do this because I’m always searching for the best, most versatile way to travel. Most of the packs I buy these days are smaller ones to compliment my Eagle Creek packs. I’m a choosy pack connoisseur, too: I often save my dollars and seek something made in the US–or in Europe, Australia or South Africa (true of pack-maker Karrimore, at one point). I don’t typically like the mass-produced stuff, which I find is not as well-made. My original three Eagle Creek packs were made in the USA, but after the company was featured on the American TV talk show Oprah, receiving the host’s endorsement, the unfortunate result is that the company’s products have since (in my opinion) been compromised and manufacturing moved overseas, likely to keep up with new demand.

Red Oxx actually designed their Air Boss bag for one-bag travelers like me. It even meets the strictest international carry-on standards.

Since a good friend just sang US company RedOxx’s praises, I’m currently drooling over the RedOxx’s Air Boss and SkyTrain. Both look like they would do the trick, but make me slightly nervous because they are a couple of inches larger than my trusty-if-“rusty” Eagle Creek laptop bag, in two dimensions. If RedOxx’s uber-affordable Extra Small Aviator Bag had a shoulder strap and could accommodate a small laptop, I would even consider trying that bag–perhaps in combo with their Gator Carry-On Bag, this would make sense (but that would make for two bags, not sure about that).

Could I fit all of my stuff in the Red Oxx extra small aviator bag? T’would be a challenge!

I suppose I could also consider the US company Tom Bihn Tri-Star, though it is probably more bag than I really need.

Note that although these bags are pricey, all come with a no-hassle, no-questions-asked, lifetime warranty–the Redd Oxx warranty, in particular, is worth a read–both companies are also noted for excellent customer service and the bags should last my lifetime.

Unless, that is, I find another that I want to test drive. Filled with of radio gear, of course. Ah, well…My wife appears to be right.

Have radio, will travel

I suppose the reason I’m entertaining this slightly off-topic travel subject is not just due to my recent travel, but because I’m now enlightened enough to realize that traveling light never means traveling without a radio. With some careful planning and packing, choosing the right bag–and travel-companion radio–the whole world is waiting for you.  And you won’t find yourself spending your travel time–and radio listening time!–watching bulky suitcases drift round on the conveyor belt at baggage claim, as you wait for yours.

Anyone else out there have a similar bag addiction?  Got one you like? Radio travelers, share your thoughts!

Perhaps listening is good for us

I’ve always believed that, over time, the process of listening through static to hear a distant shortwave broadcast, has been good for not only increasing my listening skills in general, but has been healthy for the grey matter. Seth S. Horowitz, auditory neuroscientist at Brown University, has just substantiated this belief in his NY Times piece, The Science and Art of Listening:

[…]Hearing, in short, is easy. You and every other vertebrate that hasn’t suffered some genetic, developmental or environmental accident have been doing it for hundreds of millions of years. It’s your life line, your alarm system, your way to escape danger and pass on your genes. But listening, really listening, is hard when potential distractions are leaping into your ears every fifty-thousandth of a second — and pathways in your brain are just waiting to interrupt your focus to warn you of any potential dangers.

Listening is a skill that we’re in danger of losing in a world of digital distraction and information overload.

And yet we dare not lose it. Because listening tunes our brain to the patterns of our environment faster than any other sense, and paying attention to the nonvisual parts of our world feeds into everything from our intellectual sharpness to our dance skills.[…]

Hurricane Sandy: Getting prepared

Self-powered radios can be your link to your community and to the world in the wake of a hurricane or other natural disasters.

I don’t know of many people living in eastern North America who aren’t a little nervous about what Hurricane Sandy could bring in the next few days. Several models point to some pretty severe weather and predict power outages in the wake of storm surge, high winds and rising water levels.

Of course, it’s difficult to prepare this close to a weather event as supplies are typically low and demand is high. We radio enthusiasts are well aware of the importance of radio supplies, but there’s so much more to include to have preparedness basics in place.

Sandy may or may not pan out to be a memorable weather event, but we can take this opportunity as a reminder to be prepared.

No matter where you live, spend some time preparing for natural disasters or interruptions to public utilities. We have several helpful posts on the SWLing Post which can help you with this very thing. If you do nothing else, make sure you at least read this post and this post.

Radio World looks at DRM

(Source: Radio World)

By: Ernie Franke

Once touted as the “Savior of Shortwave,” Digital Radio Mondiale has not lived up to its hype. Proposed in 1988, with early field-testing in 2000, inaugural broadcasting in 2001 and its official rollout in 2003, DRM has had a lackluster career over the last decade.

With the allure of FM-quality audio and fade-free operation, it had appeared that DRM might revive the shortwave community. Unfortunately, it has been overcome by other events, some technical and some social. The main weakness has been alternate sources of information and entertainment, fueled by the very technology that gave DRM hope.

Additionally, in areas of the world without ubiquitous social media, DRM has yet to realize receivers at a moderate cost with adequate battery life. The very processing technology that allows improved operation using the more complex DRM waveform costs more and consumes more power than the standard AM receiver. A quick look at standalone DRM receivers over the past decade shows almost a dozen companies entering the market, only to retreat when the promise didn’t materialize.

[…]The rise of the Internet has influenced many broadcasters to cease their shortwave transmissions in favor of broadcasting over the World Wide Web. When BBC World Service discontinued service to Europe, North America, Australasia and the Caribbean, it generated many protests. The shifting of resources from shortwave to Internet and television by the Broadcasting Board of Governors, which oversees U.S. international broadcasting, further reduced broadcasting hours in the English language. […]Although most of the prominent broadcasters continue to scale back their analog shortwave transmissions or completely terminate them, shortwave is still common and active in developing regions, such as parts of Africa and South America.[…]

The article then goes into an in-depth look at both the reasons for and technology behind Digital Radio Mondiale–both on the broadcasting and receiving ends.

Try that with an iPhone!


With the help and guidance of my good friend Charlie, we just repaired and aligned this BC-348-Q receiver. BC-348s were built to withstand the extreme temperatures (-60F) and vibrations on board the B-17 and other bombers, where they were used extensively in World War II. I picked this beauty up at the 2012 Dayton Hamvention for $40.

Next year, this radio will be 70 years old.

This morning, I have it tuned to Radio Australia’s Saturday Night Country on 11,660 kHz shortwave. It’s “connecting” to a wireless network over 9,800 miles away and producing beautiful, warm audio.

The Ten-Tec Hamfest–and my new (vintage) LS-166/U military loudspeaker

My only purchase at the Ten-Tec hamfest flea market this year, the LS-166/U military loudspeaker

This past weekend was the Ten-Tec Hamfest, which is held each year at the Ten-Tec factory in Sevierville, Tennessee, USA. I’m particularly fortunate in that I live within a few hour’s drive of the factory, so I make it a point to attend the Hamfest each year.

Hamfests, for those of you not familiar with them, are basically flea markets or swap-meets for amateur radio operators and radio enthusiasts of all stripes.  It’s a place to reunite with hobbyist friends and to trade, sell, or purchase new or used radio equipment. The Ten-Tec Hamfest is free, draws a sizable crowd, and what’s more, attendees get the opportunity to try out Ten-Tec radio equipment and tour the factory where their products are made. The Hamfest also coincides with the annual SEDCO DXer/Contester Conference, which is held in the same town, and begins just as the Hamfest winds down.

This year, I had not intended to buy anything. Still, I’m pleased to admit I bought only one item…

The LS-166/U loudspeaker is built like no other–it’s even gun blast resistant! Its rigid cone is well protected by thick metal screen and mesh.

My purchase:  an LS-166/U loudspeaker. This small speaker has been used extensively in military operations around the world. It’s built like a tank, was perhaps mounted in some, but used primarily used in Jeeps, trucks, and on portable radio packs. The case is made of metal and extremely durable. The two watt speaker has a permanent magnet.  It is also fungus, gunblast, and immersion resistant:  if you drop this speaker, you don’t need to worry about damaging it–rather, you may need to worry about the floor (or your foot).

Side view of the LS-166/U: though heavy, its dimensions are only 4.75 x 4.75 x 3″.

The really cool thing about this speaker is that it contains an audio transformer that–via a switch on the side–will allow you to chose between a 600 ohm primary and 8 ohm secondary impedance. The speaker sounds crystal clear, even though mine has obviously received extensive usage. That’s the great thing about military gear–it was designed for functionality, often over-engineered, and certainly built to last!

The LS-166/U is not for listening to music–it was designed primarily for radios that require a high impedance load, and for voice audio clarity. If you’re receiving orders over the radio from your commander, the LS-166/U will punch through the noise from your vehicle and surroundings. It sounds “tinny” if used to listen to shortwave broadcasters, but is actually quite effective when used to listen to amateur radio transmissions and morse code. The 300 Hz to 7 kHz frequency response is ideal for this type of application.

The schematic is printed on the inside of this back plate, which is easily removed with a plain head screw driver

The first rig I hooked up the LS-166/U to was my Hammarlund SP-600, which has a 600 ohm output. Though I know I can hook up a larger, more responsive speaker for better fidelity, there is something rewarding about hearing a speaker that has seen so much service being used once again, and still playing as if new.

As you can see from the photo below, mine lacks the knob on the side of the case.  I’ll be looking for one of these at the next Hamfest–or may just order one from Fair Radio.

If you happen to locate the LS-166/U loudspeaker at your local Hamfest, grab one! There are a lot of them floating around and they’re usually quite affordable–typically between $10-20 US (more if mint). I was lucky to pick mine up for $4. Not only is it an affordable piece of military radio history, but I think it would make an excellent external speaker for amateur radio use during outdoor events like Field Day. Indeed, I think this speaker will weather any radio challenge!

So, what else did I see at the Ten-Tec Hamfest this year? Quite a few classic receivers. Though I didn’t take many photos, I did snap a few gems…

This aluminum radio speaker reminds me of the external speakers found on radios in the early 1900s. The seller had made a custom wooden base for this one (click to enlarge)

If you visit the Ten-Tec factory, tour their radio museum, housing nearly every radio Ten-Tec has produced. One example is the  SP-325 (on bottom) a shortwave receiver which once served the US government as a training radio. They’re fairly rare, but can be found occasionally on eBay. (click to enlarge)
