Paul discovers Firedrake in an unexpected place

Many thanks to SWLing Post contributor, Paul Walker, who writes:

From time to time, I get some interesting shortwave catches here in Alaska.

Sometimes on 10 MHz, I get WWV. Sometimes I get WWVH. Sometimes I get BPM China. And from time to time, I’ve heard all three at once.

Well this clip is something a bit different…

From April 20, 2016 at 1707 UTC here is my Tecsun PL880 connected to a 225 foot long wire with audio set at 3.5 kHz while tuned to 10,000 kHz (10 MHz).

This time, I am hearing WWVH Hawaii and […] the Chinese Firedrake jammer. What’s happening is Firedrake is jamming the Sound of Hope on 10005 kHz and the signal is so wide, it’s [competing with] WWVH.

I am making no adjustments to the dial tuning or audio settings as this happens. Listen to how things fade in and out.

Star Wars sound designer is, indeed, a radio enthusiast

StarWars-LogoSWLing Post readers may remember a post I recently published in which I believed I’d identified a familiar shortwave time signal station in the Battle of Hoth scene from The Empire Strikes Back. If you haven’t read this post, feel free to do so and listen to the embedded video/audio clips.

Upon hearing this, I went so far as to muse that the Star Wars sound designer might be a radio listener. I asked our readers if anyone could confirm this–?

Well, we’ve got our answer!  I’m truly indebted to an SWLing Post reader who passed my post along to his friend, Ben, who could provide this definitive response:

“This is Ben Burtt, sound designer of the Star Wars films. A friend sent me a link to this blog thinking I would like to comment.

Ben and old recorders

“The answer is yes, I have always been a ham radio enthusiast.”


“My grandfather, Harold Burtt, operated W8CD out of his home in Columbus, Ohio 1930s-1960s. I was enthralled as a kid listening to the sounds on his receiver. I heard alien worlds and cosmic ‘voices.’

“So not only did I record his radio, but continued to do so on the Star Wars series and Star Trek as well.

My memory of the Hoth transmission was that it was WWV but it could have been CHU since I was recording all that interested me on the dial.”

Terrific! Thank you, Ben, for taking the time to respond. As I said, you’ve certainly started off this radio enthusiast’s year on the right wavelength…no doubt some of our readers will agree.

Indeed, the powerful sonic experience of the Star Wars and Star Trek films has, in my estimation, helped shape many of us into the radio/sound enthusiasts we’ve become–myself certainly included. Thank you, Ben, for this!  You’ve sharpened my ear to a greater appreciation of sound, especially filmic sound, and your work in particular.    

For readers who are less familiar with Ben Burtt’s work, check out his Wikipedia page and IMDB profile–you’ll find he’s been the sound designer on numerous influential films including the recently released Star Wars: The Force Awakens.

A special thanks to Ben Burtt for sharing these wonderful photos and kindly giving me permission to use them here on the SWLing Post.  I must say, considering my love of radio in the thirties, I especially like that photo of Harold Burtt (W8CD) in his shack.

Time station CHU in The Empire Strikes Back

Fullscreen capture 12202015 40448 AM

Earlier today, I published a post noting that I thought I heard the time station WWV in a scene of The Empire Strikes Back.

SWLing Post reader, RadioGeek, quickly corrected me: that’s Canadian time station CHU‘s data pips I’m hearing, not circa-1980s WWV.  Cool!

Listen for yourself

Here’s the clip from The Empire Strikes Back, Battle of Hoth: listen at 25 seconds and at 40 seconds (the clip starts at 23 seconds):

Now listen to the recording of CHU I made only moments ago–note the tone and duration of the data pips:

No wonder I mixed up CHU and WWV; I’ve listened to both for propagation since I was a kid.

I wonder which of the Lucas Film sound engineer(s)/artist(s) chose CHU for this scene? Anyone know, by chance? Or can anyone find out?

No doubt, that sound designer is an SWL or ham radio operator. Perhaps this may also explain the SSB-esque radio dialog between fighter pilots throughout the Star Wars films:

Please comment!

The Empire Strikes Back: Is that WWV I hear?

Fullscreen capture 12202015 40448 AMWith all of the Star Wars: The Force Awakens hype going on, I remembered that, as a kid, I thought I heard WWV in a scene from The Empire Strikes Back.

I looked through some video clips of the movie online and discovered it again this morning: I heard the WWV-like sound in the Battle Of Hoth scene. [Update: RadioGeek suggests this may actually be CHU’s date pips.]

This video clip will start around the :23 second mark; start listening for the metronomic tick in the background around :25 seconds and then again at :40 seconds:

I may be mistaken, but I believe that sounds like 1980s era WWV. Has anyone else noticed this?

WWV History: Richard’s QSL cards

Commenting on our post about Myke’s new release of At The Tone, SWLing Post contributor Richard Langley writes:

I must have first heard WWV shortly after putting together the Knight-Kit Span Master I received for Christmas 1963. I still have my log books from my high school days, which include an entry for Radio Habana on 29 December 1963 for which I subsequently received a QSL card. But I guess I didn’t log all my receptions. The first entry for WWV is dated 3 June 1966 in the last year of WWV’s operation from Greenbelt, Maryland (on government land that subsequently became the site of NASA’s Goddard Space Flight Center).


I have a QSL card for the reception of the 5 MHz signal featuring a drawing (in pink) of the Jefferson Memorial [see above].

The next entry is dated 1 December 1966, the first day of WWV’s operation from Fort Collins, Colorado.


I have one of the special QSL cards issued for confirmation of first-day reception for my report on the 20 and 25 MHz signals [see above].

I’m sure I heard WWVH early on too but my first log entry is dated 29 March 1967. I never did QSL them.

Richard: Thanks so much for sharing these special QSL cards. Wow! I had never seen the first day card from WWV Fort Collins before–what a treasure you have there!
