ARS Technica: People turn to ham radio in aftermath of Nepal earthquake

Elecraft-KX3

Many thanks to SWLing Post reader, John Drake, who shares this excellent article from ARS Technica:

“On Saturday, Nepal was shaken by a massive earthquake that registered a 7.8 on the Richter scale, causing widespread destruction in areas of dense population, and preventing aid workers from reaching more isolated villages in the mountainous regions. As of Tuesday, at least 5,000 people were dead and at least 10,000 were injured. Hundreds of thousands of people have been left homeless.

With any natural disaster, communication can often become a matter of life and death, and if phone lines are broken and cell towers crumble, relaying messages to the outside world and coordinating rescue efforts becomes that much more difficult. Add to that the fact that Nepal’s government is woefully unprepared to handle such a humanitarian crisis, and chaos reigns.

Still, some volunteers are trying to impose order on the chaos. After the quake, which shook cities in India as well as Nepal, volunteer ham radio operators from India traveled to the region to relay messages from areas whose communications infrastructure is broken or overloaded. Ham radio, also called amateur radio, is a means of sending and receiving messages over a specific radio frequency, and it is often used in disaster situations because it operates well off the grid; transceivers can be powered by generators and set up just about anywhere.

Amateur radio has taken a back seat with hobbyists in recent decades as other means of wireless communication have become cheaper and easier for people to use (you don’t need a special license from the FCC to operate a cell phone, although sometimes it seems like we’d be better for it if that were the rule). The decline in participation rates is unlikely to change substantially in the US, and the Times of India noted that awareness about ham radio is still low in India and nearby areas. Still, it has proven to be effective as a means of communication in Nepal in recent days.”

Continue reading on ARS Technica…

Transceivers like the Elecraft KX3 (above) are perfect for aid workers in need of communications in the aftermath of a natural disaster. Many modern transceivers (like the Kx3) can run for hours at a time off of battery packs, can be deployed almost anywhere and can easily be attached to amplifiers if needed.

It may take a license to operate amateur radio, but frankly it’s a fairly low barrier of entry. Morse Code tests are no longer required here in the US and all of the questions and answers are multiple choice and in the public domain.  Indeed, I found the Technician (and former Novice) license test to be incredibly educational; especially with regard to radio propagation and basic electronic principles.

Everyone should support their amateur radio clubs who actively hone their emergency communication skills. As the ARRL often quotes: “When all else fails…amateur radio.” Even if you don’t have a license, amateur radio clubs welcome visitors. You can find a fairly comprehensive list of amateur radio clubs (in the US) via the ARRL.

A Photo Tour of the National Capital Radio and Television Museum

On Tuesday afternoon, I made a pilgrimage the to the National Capital Radio and Television Museum in Bowie, Maryland, USA.  The museum is located in a modest and beautiful historic house on the corner of Mt. Oak and Mitchellville Roads in Bowie.

Museum Curator and volunteer, Brian Belanger, kindly gave me a private tour of the museum collections (the museum is closed on Tuesdays). Brian

Many thanks to Brian for taking time out of his day for the tour, and for allowing me to take some photos for the SWLing Post!

The museum has a number of display rooms with radios broadly grouped by style and decade. The first room offers examples of some of the earliest radios produced–including the venerable crystal radio (below).

Like Brian, numerous volunteers work to keep the collections in working order. This isn’t a place where vintage radios come to die; they actually come to life here.

The Hallicrafters SX-88: a rare find and a gem of engineering

Hallicrafters-SX-88

Yesterday while glancing through the QTH.com classifieds ads, I noticed a rare boat anchor for sale: the Hallicrafters SX-88.

The seller, Jeremy, describes this SX-88 as follows:

Hi [t]here, I have one SX88 in minty shape and is one of a handful that came in military green on [the] front panel for evaluation by the military. This is an exceptional radio in amazing condition. I can provide pics for someone who is seriously interested. I am open to a fair offer on radio. Please, no low-ballers. We all know what [it’s] worth…

Halli-SX-88-QTH-Ad“We all know what it’s worth–?

Well, it just so happened that my good friend (and Elmer, or ham radio guru) Mike Hansgen (K8RAT) had recently provided me with a little history lesson on the subject of the SX-88, so I did know what this rig is worth: a great deal of money.

But curiosity got the best of me, so I contacted Jeremy (a nice fellow, by the way) and asked what he was expecting to receive in exchange for his Hallicrafters SX-88? Jeremy’s reply:

“…$5,500 USD will take it. It is a very rare unit; it was… only one of about 6 [painted green]…for presentation to the military for evaluation.

That price is firm. [I] will not negotiate downward, and shipping [from Ontario, Canada] is extra.”

After receiving this response from Jeremy, I happened to think that I have the reference guide to rare/used shortwave receivers: Fred Osterman’s Shortwave Receivers Past and Present 4th edition. (Click here for more info.)

Osterman’s wonderfully comprehensive guide mentions that the SX-88 is a “highly regarded, rare and collectible model.” As for the rarity of the SX-88, he describes it thus: “Extremely Scarce.” The used price range he gives is from $3,500-7,000 US.

I also have Chuck Dachis’ book, Radios By Hallicraftersin it, he states that the SX-88 is, “the most sought-after Hallicrafters model.” Wow.

After thanking Jeremy for his response, he replied:

“It’s a lot of money for a receiver for certain, but it is a fantastic shortwave receiver as the audio that comes out of it is amazing.

It has 10 watts of audio and into a big speaker–it is second to none. The fidelity is amazing and it is the king of its kind. [For those who like] tube rigs, it is the best of its kind.

For ham purposes on AM it is amazing, and on CW I find it incredible to use.

[W]hen they built this thing they intended to pull all [the] stops out and build the best radio they could for the day with the military in mind. It was an engineering marvel for the day.

Anyway, I have played with it for years now and need to thin out the herd.”

Impressive. And while I just don’t have that kind of money to fork out for a receiver, I did ask myself the question: “If I had $5,500 to blow, would I get that Hallicrafters SX-88?”

And my answer? Yes.  In fact, I would personally drive to Jeremy’s home in Ontario and bring it back; no way I’d trust it to a parcel carrier or the post office…

Come on, you may say. For a guy who rarely pays over $50 for a vintage receiver, how could you possibly justify that kind of financial and time commitment–?

Well, let’s think of it this way.  I remember when when I paid well over two thousand for my first laptop in college. How much is it worth now? Maybe twenty dollars–?

Many people have retirement funds in investments, some of which are in a variety of innovative companies that they actually patronize–for example, Apple or Microsoft.  But how often can you find an investment that you can actually play with? One which you can turn on, tune in, work the controls, and enjoy?

Yes, I’m sure this is just the sort of justification voiced by many a vintage car collector…So, why not for a museum-worthy radio? After all, they’re not making these anymore.

I expect this Halli will not only hold its value, but will probably increase in value over time.

Ah, well; fun to ponder.  My question to you: Would you buy a $5,500 vintage receiver if you had it to spare?

If your answer is yes, and you do have the money, then you might want to contact Jeremy.

I’m very curious if there are any SX-88 owners among our readership? If so, please comment with your thoughts about the ’88!

And for the rest of us, just so we can revel in the vicarious pleasure of ownership, I’ve included some additional information about the Hallicrafters SX-88 below, including two videos.
