SIGSALY and the unlikely history of the Bell Labs Voder

SIGSALY

One of my favorite podcasts, 99% Invisible, recently featured a story on the Bell Labs’ Voder and how its innovation lead to one of the best kept secrets in WWII high frequency communications: SIGSALY.

The episode is called Vox Ex Machina and, trust me, it’s a gem.

Stop whatever you’re doing today and listen to this brilliant little documentary.

I’ve embedded the SoundCloud audio of the episode above, but you can also listen via the 99 Percent Invisible website.

Video: Listening to Radio Australia via the BST-1 car shortwave radio

Car-Shortwave-Radio

I’ve been evaluating the BST-1 car shortwave radio for a review that will soon appear in The Spectrum Monitor magazine.

I must admit: it’s mighty fun to be able to listen to shortwave broadcasters through my vehicle’s audio system.

Last week, the BST-1 saved my sanity, too. You see, I was in a rush to get to a morning appointment in town when Murphy’s Law stopped me dead in my tracks!

A construction crew began resurfacing a two mile (unavoidable) stretch of asphalt road on my route. As the road crew set up their gear, I was forced to wait a full 20 minutes (!!!!) before being allowed to pass.

Fortunately, I remembered that I had the BST-1 hooked up in the car. I tuned to 9580 kHz and there was Radio Australia. Somehow, hearing my staple broadcaster soothed my nerves. I accepted that I would be late for my appointment and simply enjoyed the moment. In your face, Murphy–!!!!

Here’s a very short video I made while stopped:

Hammarlund HQ series: A digital display modification

HQ-DisplayMany thanks to SWLing Post reader, Jeff (KB7AIL), who shares the following:

Saw the article on the DC meter in a Hammerlund HQ180.

Another mod I have seen is replacing the meter with a digital display.

http://www.electronicspecialtyproducts.com/dd101.html

It integrates with the HQ180 nicely.

They also have digi-displays in cases or use with other receivers/transceivers.

Very cool, Jeff. While I know a digital display might kill the vintage look for some enthusiasts, I have to admire such a useful modification to replace a broken Hammarlund clock/meter.

As Jeff mentions, Electronic Specialty Products has a number of external digital display boxes as well. Check out their full line of products on the ESP website.

Historic ‘Radio Row’ Finds a Home on the Internet

(Source: 73 Radio Row press release)

A new website designed for radio amateurs, SWL’ers, CB’ers and all communications hobbyists has launched on the Internet recreating the atmosphere of the famed Radio Row in New York City.

According to its founder, Richard Fisher, KI6SN, “’73 Radio Row’ takes its cue from an era when New York’s legendary radio district bustled with communications fanatics shopping for surplus and used gear along Cortlandt Street in Lower Manhattan.” 73 Radio Row’s Web address is: http://www.73RadioRow.com

The site features used radio receivers, transmitters and transceivers, as well as unbuilt kits, new/old stock antennas, Morse instruments and station accessories of all kinds.

“We are crazy about radio, the same as everyone else,” Fisher said. “RETRO is NOWtro.” For complete details, visit: http://www.73RadioRow.com or write to: 73RadioRow@gmail.com. Call (951) 395-1923.

I discovered 73 Radio Row right after it launched–I ordered a portable ER TiCK Deluxe Keyer for the very affordable price of $26 US shipped.

The keyer was dispatched immediately and I received it within a couple of days.

I know Richard Fisher (KI6SN) quite well and can certainly vouch for his integrity. In fact, he’s even giving a portion of 73 Radio Row proceeds to Ears To Our World–what a nice guy!
