Jim’s shortwave listening post is a Navy ship

USNS Button - 02

SWLing Post contributor, Jim Clary (ND9M/VQ9JC) contacted me in June to obtain details about the BBC’s Midwinter broadcast to the British Antarctic Survey Team. Jim has been working on board the USNS Sgt William R Button since mid-June. While on board Jim has no web access, but he can send and receive emails and some files. I kept Jim informed about the time and frequencies of the BAS broadcast.

Jim had hoped to make a recording of the Midwinter broadcast at sea, but timing and some technical problems got in the way and he missed the bulk of the 30 minute program.

That’s okay, though, because Jim is an avid SWL and ham radio operator. During time off, he has logged a number of stations, so I asked if he would consider making a recording for us.  I mean, SWLing from a Navy ship?!  How cool is that?!

Within a week, Jim sent me a recording of the Voice of Korea. Here are some of his notes:

I’d heard [the Voice of Korea] many times before when Stateside (and they were Radio Pyongyang at the time), but their signals were always weak and had major polar flutter. Out here, the signal was in-my-face loud, so even though the station is not much of a rare DX catch, I wanted to get them on tape.[…]

[M]y location is the east southern Atlantic Ocean, not far from St. Helena.

[…]My ship is named USNS Sgt William R Button. The ship has been active since the mid 80s and was a “motor vessel” (M/V) until we became a Navy asset in 2009.

[…]My receiver that I’m currently using is my QRP rig, a Yaesu FT-817ND. I changed over to a Navy antenna that I’m feeding with about 70 feet of 75-ohm RG-6 cable. There’s obviously some signal loss from both the length and impedance mismatch of the coax, but at these freqs it’s fairly negligible.

The antenna itself is an AS-2815/SSR-1 that’s mounted above the wheelhouse (bridge) of the ship. I can’t really describe the make up of the antenna simply because I don’t see why it works so well but it really does a good job. If I’d figured out where its feed point is a couple weeks ago, I would’ve had no problem logging the BBC’s Antarctic service!

Many thanks, Jim! We look forward to any other recordings you wish to share!

“Thought I’d forward you this information on the annual “Night of Nights” event on July 12 (U.S. local time)/July 13 UTC, which provides an opportunity for shortwave QSLs – assuming the listener understands Morse code!

I’m sure you’re familiar with this one-night-a-year happening, in which maritime radio stations rise from the dead and transmit Morse code messages again for a few hours.

As a guy who honed his CW sending skills by listening to these stations’ constantly repeating messages, I have a sense of nostalgia and gratitude toward these stations, which helped me obtain my first Novice license, WN9ICB, at the age of 15 … less than 2 months after I taped the WWV recording that I submitted.”

Many thanks for the notice and sharing your nostalgia! Brian also forwarded an announcement from the Maritime Radio Historical Society of America. The MRHS describe the event:

It’s that time of year again. Time to honor all those ops who came before us by preserving their skills, traditions and culture through on the air operations.

Why 12 July? Long time True Believers know the story. But it may be worth repeating for new arrivals and to remind everyone of the traditions we hope to keep alive.

On 12 July 1999 some very tough looking grizzled old radio pioneers had tears in their eyes as the last commercial Morse code radiogram was sent. It was the end of an era. And as the last beeps faded away into the static they witnessed the end of the career to which they had devoted their lives.

These men – and some women – had stood watch over the airwaves on shore and at sea. Theirs was mostly the business of maritime commerce. But when their ship was in peril they were called upon to send the most electrifying three letters in radio, S O S, knowing that all their fellow radio operators would press their earphones close to get every scrap of information and bring aid to their stricken ship.

Once, our coasts were dotted with great Morse code radio stations, all communicating with ships at sea. They’re all gone now… all except one, the one they called the Wireless Giant of the Pacific, located at Point Reyes.

On that sad day in 1999 another event took place. The Maritime Radio Historical Society (MRHS) was formed. We made it our life’s work to honor the men and women of wireless by restoring that wireless giant. One year and one minute later the giant’s voice once again spanned the oceas as we picked up the thread and kept the faith with our colleagues of the air.

Every year since, in an event that became known as the Night of Nights, Morse code station KPH has returned to the air, joined by KFS and the station of the MRHS, KSM.

This year our friends and colleagues at USCG station NMC have labored mightily to bring that storied call sign back to life on Morse code for the evening along with NMQ in Cambria, CA..

And station NMW in Astoria, OR will be on the air as well.

Stations WLO and KLB will join us again as hey have in years past.

This is a global and local event. Hundreds of listeners around the world will be waiting with their earphones on, waiting for the signals of the great station to once again arc over the dome of the Earth to their receivers.

You can be with us in person!

My buddy, Mike (K8RAT) also notes that this “Night of Nights” event may witness the last ever Morse communications from the US Coast Guard stations. Indeed, this is mentioned in the MHRS newsletter:

This may very well be the last time ever that USCG stations can be heard on the air using A1A (Morse) emission. As new equipment is installed the hardware and wiring for Morse has been progressively removed. And the personnel who knowledgeable in the art retire or are reassigned. So be sure to listen for these stations.

I’ll not only listen to this Night of Nights, but hope to record some of the stations as well.

The frequencies for this event are numerous! I have listed the USCG (NMC) frequencies below, but please check the MHRS newsletter for MRHS and other maritime station frequencies.

Again, Brian, thanks for the heads-up!

Happy listening, everyone!
