Immediately after packing up our table at the Dayton Hamvention, my buddies Eric (WD8RIF), Miles (KD8KNC), and I made the 30 minute journey to Bethany, Ohio, to visit the VOA Bethany museum.

Eric pointed out an article on the future of shortwave radio I published last year that the museum has posted in the hallway next to the control room (above). What an honor!

The satellite dish (above) was once used for VOA’s downlink/feed–now the West Chester Amateur Radio Association (WC8VOA) uses the dish for EME (Earth Moon Earth) contacts.

Back inside, WC8VOA has four full amateur radio operating locations stocked with Icom, Yaesu and Kenwood gear. The club president told us that an antique amateur radio station will soon be added.

Our docent took us on a tour of two vaults filled with vintage radio equipment and then a museum devoted to the legacy of WLW. The item in the photo above is a corona ball from one of the original towers–notice the holes from lightning strikes.

When Ohio-based R.L. Drake Company stopped manufacturing amateur radio equipment, samples of their full product line were donated to the museum.

The Museum is planning substantial renovations to restore the VOA Bethany Station and become a first class institution. During the restoration, the Museum is only open one day per month to the public: The third Saturday of each month from 1:00 PM – 4:00.

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

1 Reply

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.”

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

9 Replies

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).

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).

[Click photos to enlarge.]

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.

Even examples of some of their earliest radios are on the air and can be tuned to local and international stations.

This RCA “portable” (below), housed two batteries on either side of the center faceplate. Note the ad on the wall above–a couple enjoy the RCA as they recline on a beach.

Speakers of the day were pretty amazing, too–check out this hand-painted 1927 Air Chrome Double Cone Speaker, below.

The museum also has an extensive collection of studio and off-air recordings that can be played over an AM carrier throughout the building.

By the late 1920s and early 1930s, radio manufactures built gorgeous console radios, features in the living rooms and parlors of many lucky homes.

This E.H. Scott All-Wave 23 console (above and below) sported not only twenty-threee vacuum tubes, but a large, robust internal speaker. Radio collectors consider the All-Wave 23 to be one of the finest performing radios of the vacuum-tube era.

The museum also features the Zenith 12-S-232 tabletop radio with working shuttle dial–a futuristic band-switching mechanical wonder with a stunning dial.

A number of tabletop and portable radios that span the decades have found their homes in this museum. No doubt many SWLing Post readers cut their teeth on these classics!

I love the design of the Garod Model 5A2–wow! And I’m sure many kids of the fifties wished they had an official Hopalong Cassidy AM radio (below).

The museum, of course, also houses a large number of classic televisions.

Radio stations and benefactors have also donated many items used in the industry, both in broadcast and retail.

Brian was also kind enough to take me to the building, next door, where they repair radios and store others for eventual rotation into the collection.

Museum volunteers also teach radio repair and restoration classes.

The number of classic ham radios, home brew receivers and transmitters was simply amazing. Indeed, I felt like a kid in a candy shop!

By the end of the tour, I had decided to become a member of the National Capital Radio and Television Museum. Even though I live a few states away, I like knowing that my membership funds not only help preserve vintage radios and televisions, but also provide me members-only access to many of their scanned archives.
